Hi Readers! Visual representations are cyber attack maps, which display in real time (or close to real time) where Internet-based attacks occur, the nature of the attacks like a DDoS attack, a botnet traffic attack, a scan, and occasionally the affected services or countries. They are dramatic, arcs and heatmaps and blinking dots, but do not just look cool. This is a plain, useful way of explaining how these maps are useful in cases of recent attacks, some real-life examples and their limitations.

Quick respond to situational awareness

Several seconds and minutes count when the Cyber attack starts. Cyber Attack maps provide the security teams, with a real-time shared perspective of what has been happening within networks and regions. That assists teams to identify gigantic DDoS bursts, abrupt bot traffic or targeted scanning, which might be a preliminary step in a larger intrusion. Security vendors (and national CERTs) use this live feed to allocate triage and mitigation resources in the areas they are most needed. 

Assist in mitigating and Reducing impact

Cyber Attack Maps are more than pretty, they feed dashboards and automated systems which have the potential to initiate defenses. As an example, DDoS protection systems such as those sold by Arbor/NETSCOUT or Imperva will combine the global threat intelligence displayed on cyber attack maps in order to determine when to redirect traffic, when to use scrubbing centers, or when to apply rate-limiting – all of which can halt an outage within minutes. Such integration is among the factors that made certain recent waves of DDoS threats contained in hours. 

Transparency and Awareness of People during National Events

Now Cyber Attack maps aimed at the public when the targeted government or large service include information that can be used to communicate the extent of the event to the citizens and partners without exposing sensitive forensic information. In a DDoS attack that occurred against multiple Italian government locations and airports near the end of December 2024, increased visibility of the attack and timely response minimized the impact on service disruption of the attack, demonstrating that visibility and coordinated response are important factors. Thus, in this case it is mandatory to have the cyber attack maps. 

Facilitating Threat investigation and trend identification

Cyber Attack maps receive telemetry like the scan logs, botnet C2 sightings, volumetric traffic streams. That past and real-time data allow analysts to discern new trends – e.g., there are a bunch of specific exploit scans before a ransomware or data-exfiltration campaign can occur. This assists teams to predict the subsequent stages of an attack and fixing sensitive services in less time. Among the key protegees (such as cloud and software providers), telemetry and maps are used to contribute to broader threat intelligence. 

Enhancing inter-organizational cooperation

Maps are a ubiquitous point of reference to ISPs, CERTs, network operators, and enterprises since they are both visual and usually publicly available. The sharing of a common picture also facilitates easier exchange of Indicators of Compromise (IoCs), blocklists, or routes of traffic scrubbing between organizations, which enhances better protection to the community. There are guides and posts referring to them as the best cyber attack maps, but they also highlight their importance as conversation starters within security communities. 

Awareness, policy support, and Training

SOC teams and executives can learn more about attack history with the help of attack maps: Cyber attack maps demonstrate how the attack will occur in time and geography. Observed trends such as an increase in bot activity or attacks driven by AI can guide policy-makers and operators of infrastructure to make investments in resilience and focus on hardening of critical services. Industry reports have mentioned that attacks are increasing in pace and automation, and thus such visibility is more important than ever. 

Critical constraints: Cyber Attack maps’ Prohibition

It is also necessary to understand what attack maps are not fixing:

1. Partial view / sampling bias: A lot of the maps indicate database of one or more sensors, partners, or honeynets, but not of the entire internet, and therefore may miss or undercount attacks. 
2. Identifying the source is not easy: Maps can display an origin IP or a nation, but attackers apply spoofing, VPNs, botnets, or compromised servers, respectively, therefore, geographic arcs can be false. 
3. False positives and noise: Automated scanning and the legitimate large traffic flows may be interpreted as attacks; before the drastic actions, the analysts need to confirm the map alerts. 
4. No alternative to profound forensics: Maps provide superficial, fast knowledge. Root-cause analysis, endpoint forensics, and incident response teams are still required to contain, respond to, and understand what happened.

Practical Implication – The way they should be applied in organizations

Embed map feeds in your SOC – be an expedient alert channel, slap them together with internal telemetry like the firewall, EDR, and SIEM

Auto safe mitigation – with high-confidence patterns (e.g. volumetric DDoS) enables rate-mitigation or scrubbing to be automatically triggered. 

Disclose findings to the peers and CERTs – group intelligence reduces reaction time and lessens collateral damage. 

Exercises and planning Activities: Use maps in exercises and planning — run tabletop incident-response five to map scenarios to enhance preparedness.

Final thought

Cyber attack maps do not work magic but it is a strong situational tool. They can alleviate attacks and their effects together with rapid reaction to incidents and cooperation among different organizations, when supported by good telemetry. However, do not forget their limitations: map alerts should be considered as an initial warning mechanism that has to be followed with due validation and forensic investigation.

Hi Readers! With the ongoing shift of businesses towards cloud storage, there remains a question—that of how to ensure the security of organization’s sensitive data that is stored in the different platforms. In due time, that is where the Cloud Access Security Broker software, in short CASB comes into play. As the middlemen between the users and the cloud services, the tools embody the modern cloud security’s backbone. Let us now witness the main features of CASB, its necessity, operation, and the very best of CASB among the world’s cybersecurity leaders in 2025.

What Does Cloud Access Security Broker Software Mean?

Cloud Access Security Broker (CASB) is a cybersecurity service that stands in between the users and the cloud service providers. It ensures that the organizations are able to securely execute the cloud applications such as Google Workspace, Microsoft 365, Salesforce, and AWS without the risk of sensitive data getting compromised.

To put it differently, you can visualize the CASB as a guard dog that is always aware of who is accessing your data, from where, and for what purpose.

CASB solutions come in handy for the companies to:

• Apply the security measures
• Find and block the intruders
• Adhere to the rules and regulations
• Protect the private data over the shared cloud spaces

If you want to know all the details, then look at the enlightening Cyber News – Cloud Access Security Broker software. 

Why CASB Software Plays a Major Role in 2025?

The move to remote work and multi-cloud environments has greatly increased the complexity of security issues. The use of traditional firewalls and on-premises tools is no longer effective.

Here are the reasons why CASB software has become a must-have:

1. Cloud Expansion – Companies are using a multitude of cloud apps on a daily basis. CASBs are the ones who ensure that the access is secured in all of them.
2. Data Leakage Prevention – CASBs are the ones who constantly keep an eye on data in motion and even data that is stored, and they intervene when there is an unauthorized sharing or uploading attempt.
3. Compliance Assurance – Due to the existence of laws such as GDPR, HIPAA, and ISO 27001, CASBs have evolved into an automated system that facilitates compliance reporting.
4. Threat Protection – The first thing to go after is the most vulnerable part; advanced analytics and AI can even prevent this by making a call on detection of suspicious behavior or an account takeover.
5. Visibility and Control – With the help of CASBs, organizations can be sure that they have complete visibility of all types of Shadow IT; thus, employees cannot use any apps without permission.

What is the Working Principle of a CASB?

In order to understand how Cloud Access Security Broker software works in the background, we should look at its four main aspects, which together form the “CASB Framework”.

1. Visibility – Keeping an eye on cloud consumption and recognizing the usage of unauthorized or risky apps.
2. Compliance – Making sure that the use of data follows the industry and company standards.
3. Data Security – The goal here is to encrypt, tokenize, and set access rules, in order to keep the sensitive information safe.
4. Threat Protection – This software is beneficial in the detection of deals with malware, insider threats, that is not of the unusual behavior.

In reality, a CASB works by connecting to your current security solutions (such as firewalls and identity management tools) that are already in place, thus forming one consolidated layer of protection against attacks through cloud ​‍​‌‍​‍‌​‍​‌‍​‍‌apps.

Major Advantages of Cloud Access Security Broker Software

To see the immediate gains that businesses reap on using CASB tools a little closer, we shall consider the immediate gains:

1. Unified Cloud Security

CASBs monitor and enforce as opposed to having to handle several security tools per app.

2. Enhanced Visibility

This software is known for the cast of the shadow IT, which many of the employees use, like the unsanctioned apps that they use and have the chance of leaking data.  

3. Advanced Threat Detection

Through machine learning, CASBs will be able to identify suspicious logins or data transfers in real time.

4. Comprehensive Command over Compliance

Now it is obvious that this software is meant to streamline any of the compliance issues associated with the  automated audit trails and reports. It can be the GDPR, HIPAA, or CCPA.

5. Data Loss Prevention (DLP)

Cloud automatically recognize and prevents attempts to share/upload sensitive data to unsafe locations.

Leading CASB Solutions in 2025

The following are some of the best Cloud Access Security Broker Software products that have created ripples in the field of cybersecurity based on their performance, features, and reliability:

1. Microsoft Defender for Cloud Apps -Deeply integrated with Microsoft 365 and Azure, and provides the best level of data protection.

The Future of Cloud Access Security Broker Software

With the development of the cloud environment, CASB solutions are converging with the Secure Access Service Edge (SASE) platforms. This merger brings together CASB, SWG (Secure Web Gateway), and ZTNA (Zero Trust Network Access) into a single and formidable cloud security framework.

CAEBs will be further developed by artificial intelligence and automation to become more proactive in identifying risks and anticipating security threats.

Threat actors successfully breached the financial system of dozens of large firms by exploiting a hidden security flaw in Oracle’s widely used E-Business Suite (EBS). The attacks probably started months ago and incorporated a highly sophisticated approach —‘fileless’ malware — to access the large pool of sensitive data from endangered databases before asking for ransom from targeted companies. In this article, we will explain Oracle EBS attacks that recently left netizens shocked and concerned. 

The Zero-Day and Scope of Oracle EBS Attacks

The attacks were first noticed by Google Threat Intelligence Group (GTIG) and Mandiant after the use of Oracle EBS by the industry leaders. EBS is basically a tool for managing the finances of large companies, which started receiving extortion emails due to the recent Oracle EBS attacks. The main issue lay in the highly critical security flaw that Oracle failed to fix —CVE-2025-61882. This type of vulnerability is called ‘zero-day’, which enables hackers to launch unauthorized code on a target’s infrastructure without a password. 

Security researchers unveiled that the campaign successfully impacted many of the firms and allowed the invaders to steal a large amount of data. The scale and sophistication of the operation instantly warned of the involvement of a key, well-resourced attacker. It has been confirmed that CI0p was involved in the attacks, and they were successful in breaching data from the EBS starting in August. 

At first, Oracle stated that the attacks may include exploitation of unknown vulnerabilities patched in July. However, on October 4, the tech giant confirmed that a zero-day flaw had been exploited. 

Here is how you can prevent your business from account takeovers using IP Intelligence. 

A ‘Fileless’ Malware

To make the Oracle EBS attacks possible, the threat actors used sophisticated, multi-stage malware, which was developed mainly to prevent detection. Instead of installing conventional software files, the invaders incorporated a corrupt template within the endangered Oracle EBS databases. 

According to researchers, two main branches of these tools, named ‘fileless’ malware, were incorporated into the Oracle EBS attacks. They remain in memory or within the database structure, making it difficult for standard security software to identify them. GoldVein.Java was dubbed a downloader to extract a second-stage defense. 

The second category was complicated, as well as a multi-layered chain of Java programs:

• SageGift began the process
• SageLeaf followed, sowing the seeds
• SageWave was the last deployment tool that allowed hackers to access and steal data. 

Extortion and Financial Operation

The final goal of Oracle EBS attacks was financial. After stealing the data, the invaders sent extortion emails directly to the organizational executives, asking for money in exchange for data protection. The emails tried to use the image of the notorious ransomware group CI0p, a strategy often used to increase concern and compliance. 

Nevertheless, the forensic analysis conducted by Mandiant and GTIG revealed that the digital fingerprints are of a different group that is equally harmful. Oracle EBS attacks a collective known as FIN11. This group is not renowned for large-scale data theft, and the approaches and techniques used in this attack strongly suggest past operations related to the group. Historically, FIN11 targets widely used company software with zero-day flaws to increase its number of targets. 

Exploitation Started Earlier

One of the most concerning facts unfolded by the reports is the timeline of Oracle EBS attacks. The attacks were publicly announced in early October, but the exploitation of the zero-day flaw started back in July 2025. 

This timeline is critical since it happened just before Oracle launched its scheduled security patches for other concerns in July. This suggests that the invaders were either testing their extortion campaign or actively targeting the systems for two months before the security experts could identify the vulnerabilities. This is how the cybercriminals remained undetected from the beginning. However, the full extent of Oracle EBS attacks and their impact is still unknown. 

Here is how to prevent ransomware attacks by strengthening network defenses. 

Proof-of-concept (PoC) Was Real?

Indicators of Compromise (IoCs) posted by Oracle revealed that the leaked Proof-of-Concept was original, which was later confirmed by an analysis of the PoC carried out by a security company WatchTowr. 

The exploit chain shows a higher level of effort and experience, with a minimum of five different bugs brought together to make Remote Code Execution possible. The cybersecurity industry expects other hackers to use CVE-2025-61882 in their arsenal, and they may still have sufficient targets to target. 

As reported, Censys experienced more than 2000 internet-exposed cases of Oracle EBS. The Shadowserver Foundation has found more than 570 significant vulnerabilities. Both Censys and Shadowserver experienced a higher number of Oracle EBS attacks in the US and China. 

The overall sequence of events was broken down by a recent report. 

• Send an HTTP POST request including a curated XML to /OA_HTML/configurator/UiServlet to influence the backend server to send arbitrary HTTP requests using a Server-Side Request Forgery (SSRF)
• Utilize a carriage return/line feed injection to launch arbitrary headers in the HTTP request influenced by pre-authenticated SSRF
• Utilize this vulnerability to transfer requests to an internet-exposed Oracle EBS application and inject a harmful XSLT template.
• The Oracle EBS attacks exploit the opportunity that the JSP file can load an unknown stylesheet from a remote URL. This, unfortunately, opens the door for the threat actors to make the arbitrary code execution successful. 

The company stated that this combination allows an attacker to control request framing through the SSRF and then make use of the same TCP connection to chain more requests. This increases reliability and reduces noise. 

CI0p has been using many vulnerabilities in Oracle EBS since July-August and has successfully stolen huge amounts of data from multiple victims. Evidently, the company believes that CI0p is involved in this, and they expect to see the full extent, indiscriminate exploitation from different groups within days. If you work on Oracle EBS, this is the time to stop. Patch instantly, explore aggressively, and strengthen the controls quickly. Instead, you can choose these applications for your industry. 

Google recommended that the Oracle EBS users use emergency patches instantly, track malicious templates in the database, limit outbound internet access, track and analyse network logs, and use memory forensics. The company also published a list of indicators of compromise.

Apple has warned about the data privacy concerns related to the Google-owned Chrome browser to its large user base of 1.8 billion iPhone users. The brand has asked users to remove the Chrome browser due to the rising privacy and security issues. Apple identified the increasing issues with the way Google Chrome obtains, stores, and uses users’ data without taking consent. This raises concerns about the integrity of Google’s management of personal data. 

Apple’s warning is associated with the wider influence it has on users towards its own Safari browser, which the tech giant claims is a more privacy-conscious alternative. The company posted a YouTube video in which Apple highlighted the potential risks posed by Chrome and practices that have come under scrutiny from privacy advocates, decision-makers, and regulators. Let’s disclose the case in this article. 

Google’s Data Practices Under Scrutiny?

The basis of Apple’s complaint against Google Chrome lies in the way it tracks and stores user information. For Apple, Chrome’s dependence on third-party tracking cookies, which monitor the online behaviour of its users, is a potential breach of user privacy. These tracking cookies gather data about the browsing habits of the user, their basic information like age, location, search history, and sometimes their banking details. These are all collected without informing the users. This information is then used to create personalized advertisements that Google uses to target people with specific interests. 

Apple’s warning to avoid Chrome comes during the increasing concerns for the governments across the world, mainly in the Western countries, where regulators have already charged a hefty amount from Google for similar privacy breaches. These penalties are the outcome of accusations that Google breaches data protection laws, such as the General Data Protection Regulation, by collecting user data without their knowledge. Similar concerns were already raised by Cisco Talos, which we covered in our previous article. 

How Safe is the ‘Do Not Track’ Option?

Although Chrome offers an option- ‘Do Not Track’, Apple has cited that very few users are aware of its limitations. The industry experts state that this feature does not offer proper privacy protection and may not be effective in stopping Chrome from extracting data. The feature is often considered something beyond a symbolic gesture. Hence, users may feel that their data is in control, but Google continues to collect large amounts of data in the background. 

Furthermore, Apple has questions about the transparency of the data practices of Google. Even after the claims made by the firm, there is no guarantee that Chrome is properly adhering to the data privacy standards and avoiding tracking. Critics have argued that Chrome users may struggle to protect data collection without reliable protection. They could be vulnerable to personalized ad targeting and other types of digital surveillance. 

Political and Government Involvement

This scenario took a dramatic shift in 2024, when the White House presented the option to solution to sell its Chrome browser to the US government as a way to overcome the increasing security and data privacy concerns. This recommendation was associated with the broader discussions regarding controlling Big Tech firms, mainly related to the amount of data they gather and their impact on the public’s faith. 

This matter became even more prominent when members of the Trump rule publicly forced Google to sell the Chrome browser or face potential penalties. This administrative case was influenced by growing concerns over national security, data sovereignty, and the need for robust privacy protections in the digital era. This pressure turned into the new debates over whether some tech giants like Google should be under pressure from stricter government regulations. 

Chrome’s Data Collection Practices

In the first quarter of 2024, a major news portal released an in-depth investigative report that focuses on the scope of Chrome’s data collection practices. The report revealed that Chrome’s data collection extended far beyond casual browsing behaviours. The browser was found to keep an eye on and record a variety of personal information, including age, location, preferences, and detailed search patterns of the users. However, it was more disturbing that Chrome’s tracking mechanisms could collect more sensitive information like bank account details and login details. This type of surveillance has the potential to make people prone to serious privacy issues. We discussed the weak security of Google Chrome previously. 

Growing Need for Strong Privacy Management

Since the digital landscape is increasingly influenced by firms like Google, the data privacy concerns have never been so prominent. The access to large amounts of personal data for the company has raised alarms, mainly as these firms monetize this data through personalized advertisements and other ways. Do not worry, Microsoft 365 Cybersecurity safeguards sensitive data in high-end industries. 

In turn, Apple has increased its commitment to user privacy, which makes it a winner of data protection in the world of digital tracking. With its recent alarms about Chrome, Apple sends a clear message that it focuses on privacy and wants to safeguard the fundamental right. 

Since the battle over privacy rights has been surging, it is yet to be seen how the government and tech firms will adapt to the evolving world of data security and digital privacy. However, it is obvious that users are increasingly becoming aware of the problems related to their browsing behaviour, and they are looking for more transparency, control, and protection from the firms that gather their data. If you want further security, you can explore our iOS application Penetration testing for end-to-end security. 

Summary

Overall, Apple has recently issued a warning to users to stop using Google Chrome due to rising data privacy concerns. Google claims to safely collect and store the data, but it is unclear whether it stands by its words. Apple finds the accelerating concerns over user data, which pave the way to its Safari browser. The data collection practices by Google Chrome have been scrutinized over the years. Hence, they need stronger regulations and transparent policies to tackle this situation. I believe it is important for such a tech giant to maintain its reputation through compliance.

In this digitally advanced landscape, ransomware attacks have undergone a dramatic shift, becoming one of the most severe and disruptive types of cybercrime. Ransomware causes a loss of billions of dollars globally, ranging from personal data breaches to large-scale business disruptions. With the attacks being advanced and frequent, the main concern lies in whether you can prosecute ransomware criminals with a legal note. Well, the question can not be answered in a simple sentence. Although there are legal measures to address cybercrimes, prosecuting ransomware criminals is not an easy process. Hence, this article is particularly prepared for law enforcement agencies, which often find it challenging to overcome these issues. 

What is a Ransomware Attack?

Ransomware is harmful software that invades the victims’ data, making it inaccessible until the victim pays the ransom, generally in cryptocurrency. The attackers often threat to leak, dismantle, or withhold sensitive data if their demands remain unmet. Although some ransomware criminals target the general public, the majority of cases target businesses, healthcare firms, and governmental bodies, which are likely to pay a substantial amount to the criminals to avoid operational disruptions or reputational damage. We have our separate article entirely on understanding Ransomware that you must learn to avoid it beforehand. 

Hindrances to Prosecute Ransomware Criminals

Anonymity and Encryption

One of the biggest challenges in prosecuting ransomware criminals is the anonymity. Criminals generally use dark web apps and cryptocurrency to conceal their transactions, which makes it problematic for authorities to track their identities. The use of safe communication channels further protects the cybercriminals from identification. The technologies ensure that the location, identity, and financial information remain confidential from criminals who complicate the case.

Jurisdictional Problems

Ransomware attacks often expand across borders, as criminals can operate from different countries where legal regulations are either weak or non-existent. A significant issue for international law enforcement is the lack of universal legislation for prosecuting criminals that involved in multinational crimes. For example, a criminal in Russia targeting an organization in the UK may never face prosecution if they do not appear in a jurisdiction that finds the case a crime. Even if the criminal is caught, there could be legal hurdles preventing them from being criminals to face penalties in the victim’s country. 

Advanced Attack Means

Sophisticated ransomware groups are increasingly growing. Many are now operating as Ransomware-as-a-service models where developers rent out their ransomware tools to other criminals in exchange for a share. This complicates the prosecution procedure since it can be problematic to find who is actually responsible for the attack. Moreover, many criminal groups use double extortion strategies where they not only access data but also threat to disclose the data publicly. This is what makes it challenging for law enforcement to get back the data or cover the damage. Recently, we talked about a new ransomware Lorenz which is causing concerns for the businesses globally. 

Lack of Reporting and Underreporting 

Even after the increasing cases of ransomware attacks, many victims, mainly smaller organizations, choose not to report the crime. The risk of reputational loss or regulatory scrutiny can result in a lack of transparency in the reporting procedure. This underreporting affects the ability of the legislation to navigate the scale of the vulnerability and create actionable steps to prosecute the perpetrators involved in these attacks. 

Existing Legal Frameworks and Mechanisms

Although prosecuting ransomware criminals could be complex, there have been some efforts made at both the national and international levels to reduce these cases and bring justice to the victims. 

International Cooperation

Several international institutions like Interpol and Europol are making efforts to improve collaboration between nations on cybercrime scrutiny. Furthermore, countries are trying to establish bilateral agreements to share cybercrime intelligence. However, several countries are still lagging behind when it comes to strong legal frameworks for managing such crimes. 

US Measures and the Department of Justice

In the US, the Federal Bureau of Investigation and Cybersecurity and Infrastructure Security Agency are trying to disrupt ransomware networks. Recently, the US Department of Justice has handled many high-profile ransomware cases. For example, the REvil ransomware group was arrested in 2021. The US government has also prioritized going after the payment infrastructure, which features ransomware operations like cryptocurrency exchanges, which allow illegal transactions. 

Furthermore, Executive Orders and legislation like the US Cybersecurity Maturity Model Certification and the Ransomware State and Local Government Cybersecurity Act are influencing the firms to improve their cybersecurity protections and report ransomware cases in real time. 

Legislation and International Standards

From the legislative point of view, many countries are imposing stringent penalties and legislation aimed at fighting against ransomware. For example, the General Data Protection Regulation in Europe requires the victims to report the ransomware attacks within 72 hours of happening. Failure to comply can lead to huge penalties, which makes reporting an important task. 

International Acts like the Budapest Convention on Cybercrime are also involved in developing a standardised legal approach to cybercrime. However, the enforcement of this legislation remains challenging because of the conflicting national interests. Previously, we discussed some select strategies to manage ransomware attack successfully. 

Final Verdict

To answer the question of whether the prosecution of cybercriminals is possible or not, we need to discuss every possible aspect. In simple terms, the answer is both no and yes. Although there are some legal ways to prosecute ransomware criminals, the success rate is low and relies on different factors like international cooperation, potential to find out and track the invaders, and the legal tools for law enforcement. The nature of cybercrime, mainly ransomware, needs a global approach that integrates technology, policy, and collaboration. 

With the improvement of investigative tools and techniques, there is an increasing chance of prosecuting the ransomware criminals. Despite this, there are some challenges that suggest time and resource-consuming ways to hold the perpetrators accountable. Therefore, the authorities should focus on building a more strong and robust legal system. Nevertheless, due to the rising global cooperation, better legal frameworks and innovative approaches, we can expect that the ransomware criminals will face legal consequences and victims will find justice.

Considering the ongoing movement of digital technology, building a robust information technology (IT) infrastructure is of paramount importance. The IT sector brings together innovation and interconnectedness to ensure the safety of digital assets and private data. Science companies are becoming increasingly dependent on the IT infrastructure, and they are becoming more prone to cybercrimes and risks. Vulnerability Assessment and Penetration Testing (VAPT) has thus become a mandatory requirement for the IT field to protect the major defense against significant cybercrimes. Let’s begin with the basics and understand how this mandatory requirement benefits the companies. 

What is VAPT?

VAPT is a methodological technique that improves a company’s security posture by detecting, prioritizing, and managing risks within its infrastructure. It also helps you comply with the different industry standards throughout the year. VAPT is also defined as the process of identifying and tracking all potential threats in the infrastructure with the aim of mitigating them. It is carried out by security experts who have experience in offensive exploitation. If you are looking for a reliable VAPT expert, then you should check these VAPT services. In simple terms, VAPT is a proactive hacking task wherein you simulate a hacking attempt on your IT infrastructure prior to potential criminals.

What are the Different Types of VAPT?

There are six types of VAPT that we will discuss in this section:

Organizational Penetration Testing

Organization penetration testing is a holistic approach that simulates real-world crimes on the IT infrastructure, including cloud, networks, APIs, web, and mobile applications. It is followed by a multi-pronged approach which leverages vulnerability evaluations, social engineering techniques, and use kits to find out risks and related attack actors. 

Network Penetration Testing

Network penetration testing uses ethical hacking approaches to consciously probe your network defenses for vulnerable data storage and transfer risks. Standard techniques of Network penetration testing include scanning, fuzzing, exploitation, and privilege escalation. In this type, the experts map out the network architecture, find out the systems and services, and then focus on automated tools to gain unauthorized access. 

Web Application Penetration Testing

Experts like IEMA use both manual and automated tools to examine the weaknesses in authentication, authorization, input validation, and business logic. The experts try to inject malicious code, manipulate sessions, and use logic flaws to find out, prioritize, and overcome risks even before the attackers. We have previously discussed the top 5 reasons to conduct VAPT of web applications that you must learn. 

Mobile Penetration Testing

Mobile penetration testing considers static and dynamic analysis to identify vulnerabilities in the code of the mobile app, use business logic vulnerabilities and weaknesses of inter-app communication to spot common vulnerabilities and exposures (CVEs), and zero days. 

API Penetration Testing

Application Programming Interfaces (API) VAPT copies real-world attacks by mindfully requesting to discover vulnerabilities like broken authentication, injection flaws, authorization flaws, and IDOR. 

Cloud Penetration Testing

Cloud penetration testing aims to evaluate the risks in your cloud configurations, APIs, access controls, and storage mechanisms. It focuses on different automated tools and manual testing. 

Is VAPT Mandatory?

The VAPT evaluates the vulnerabilities during the data and information security examination. Furthermore, the assessment helps in making the right measures to safeguard against cybersecurity threats. It offers companies key insights into their security posture by finding out the areas for immediate intervention. ISO 27001 information security standards require VAPT for firms looking to maintain data integrity and safeguard customer trust. 

Benefits of VAPT for the IT Field

We have already discussed the real benefits of VAPT in our previous article. However, its benefits in IT is discussed here. A company can reap off the advantages of VAPT assessment with the ISO 27001:2022 standard. The importance of ISO 27001:2022 certification lies in:

• IT companies should prioritize VAPT to ensure strong security postures. Furthermore, it helps the firms to safeguard their information assets against potential cyber vulnerabilities and privacy breaches. 
• VAPT encrypts valuable data of customers and clients from criminals by finding possible weaknesses in a network or system. Businesses should carry out a risk assessment to detect potential threats and take steps to proactively mitigate them and reduce the risk of data breaches from criminals and invaders. 
• VAPT mimics a real-world attack to examine the efficacy of the existing security measures. Furthermore, this procedure helps in finding out the loopholes in network security and makes their defenses strong against cybercrimes. 
• VAPT protects the confidential data and the company’s reputation. A single cybercrime can have severe impacts, including monetary losses, reputational damage, and legal repercussions. 
• IT companies should thus adhere to the information security and data privacy legislations like GDPR, ISO 27001, SOC-2 Certification, and so on. Performing regular VAPT assessments can help companies adhere to the international as well as national legislation. 

Process of VAPT 

Phase 1: Planning & Scoping

In this phase, businesses need to define the goals, objectives, and boundaries for conducting VAPT. It encompassess navigating the important assets to be tested, deciding the methodology, and compliance prioritizations. 

Phase 2: Information Gathering

In this phase of VAPT testing, the team collects data regarding the target systems, network architecture, and possible risks using publicly available information and effective tools. 

Phase 3: Vulnerability Assessment

This stage focuses on vulnerability assessment using advanced scanners and automated tools. It also identifies the possible weaknesses in the infrastructure, security posture, and configuration settings. 

Phase 4: Penetration Testing

In this step. Security experts try to exploit identified risks using hacking methods. This simulates the real-world attacks to evaluate the probable impact and efficiency of the existing security measures. 

Phase 5: Reporting & Mitigation

After penetration, the team delivers a complete VAPT report that highlights the vulnerabilities, exploitation, and recommendations for mitigation. This stage requires a structured plan to address identified risks and strengthen the organization’s existing security posture. When patching is delayed due to third-party components, organizations should remediate vulnerabilities through virtual patches, which are recognized as compensatory controls by all major compliance frameworks.

Phase 6: Rescan & Certificate Issuance

In this final stage, the experts often provide rescans to check all, generate proper reports and issue VAPT certification, which features compliance audits. 

Summary 

VAPT is a key tool for finding out and mitigating information security risks and vulnerabilities. Furthermore, the evaluation tracks the organizational compliance with the legislation and standards to safeguard the user’s confidential and sensitive data.

Whether you are using an Android phone or an Apple iPhone, there is a risk of security since organizations like Google or Facebook refuse to provide ownership to their users over the data share. Although Apple claims to sell products and services in accordance with customer privacy, there is no guarantee that the company will continue to keep its promises or uphold its previous commitments. 

Technically, smartphone manufacturers, app developers, and social media channels should obtain consent from users before accessing their data or content. However, in practical, this does not work that way. The New York Times reported that ‘your apps know your every detail and they are not a secret anymore’. Thus, we are here to help you with some effective steps to make your smartphone private and protect your privacy. 

Why is Your Smartphone Privacy Important?

There are several reasons why your privacy on smartphones is important.

Data is a Goldmine

In this world of data-driven businesses, your personal data is more valuable than ever before. Big tech businesses like Google, Facebook, and others make billions of dollars by gathering, analyzing, and selling your personal information. Your location, browsing behaviour, search history, and even personal conversations are used to establish detailed profiles. This is done to target the advertisements more effectively. However, do you know that this information is often collected without your knowledge and sometimes even without consent? Hence, by using a smart lock like WebParsab, you can secure your smartphone. 

Targeted Manipulation

Modern technology is designed to continuously engage you, but sometimes it manipulates you too. With the large amount of data obtained from your smartphones, companies can predict your next move and influence your decisions. It could encourage you to make impulse decisions or refine your political views. For example, social media platforms use algorithms to track your behaviour and actions to engage you more. This is often driven by your personal data, including likes, comments, and content that you would have shared. Thus, when you interact more with the site, it learn more about you and your preferences. 

Hence, by ensuring you make your smartphone private, you can protect yourself from such type of manipulation. When you use a smartphone that focuses on privacy, you stop the algorithm from entering your private spaces. 

Identity Theft

Cybercriminals mainly target smartphones for sensitive data, including personal information and financial credentials. We have already discussed some recent data breaches, including the Salesloft data breach and US data breaches. The personal data of millions of customers and the general public, including email IDs, mobile numbers, and even financial credentials, has been exposed to vulnerabilities. If the information is accessed by the wrong hands, it can be used for fraud purposes, like accessing bank accounts or making unauthorized transactions. 

Surveillance 

Smartphones continuously gather data on your actions, behaviours, and preferences. Even if you are not using applications, they can still collect data in the background. The apps can then send data to third-party firms. This type of surveillance impacts your personal freedom and makes you feel like someone is watching you. 

Right to Privacy

Privacy is a fundamental human right that must be respected and not compromised for the sake of convenience. However, in his technologically advanced environment, privacy is often considered a luxury that should not be taken for granted. No one should be forced to compromise their privacy in exchange for a smart device. 

How to Make Your Smartphone Private?

Turn off Location Services

Our security professionals suggest turning off the location services on your iPhone or Android device as the best way to make your smartphone private. Make sure you allow those apps to use your location that clearly need the information to function properly. 

Turn off Location Services on iPhone

• Go to settings
• Click on Privacy & Security
• Hit on Location Services
• Turn on the Location Services 

Turn off Location Services on Android

• Go to settings
• Scroll down and click on the location
• Tap Location, then turn off the ‘Use Location’ option

Avoid Mobile Applications

Data sharing goes both ways. Facebook always tracks your online surfing behaviour even if you are not on Facebook at that time. This is because many sites share data on you with Facebook. You can check the data and clear it out. Follow the steps below:

• Go to the settings & privacy 
• Click on Settings
• Choose Meta Accounts Center
• Hit on your information and permissions
• Turn your activity off, Meta technologies

It is recommended to avoid applications like Facebook Mobile that access as much personal data as possible from your smartphone.

Use a Browser with Incognito Mode 

You can start using a browser that has an incognito mode, like Google Chrome. Incognito mode in Chrome is a privacy feature that enables you to browse the internet without storing any past data, internet cookies, site information, or personal data. When you launch incognito, Chrome stops tracking the web pages you visit, the files you access, and your browsing history. After closing the incognito tabs, Chrome removes all the data. Hence, it is particularly beneficial for secure browsing, which can make your smartphone private. 

Turn on Chrome Incognito Mode on MacOS

• Open Chrome
• Click on three dots
• Go to a New incognito window
• Continue browsing 

Turn on Chrome Incognito Mode on Windows

• Launch Chrome on your Windows device
• Click on three dots
• Go to the New Incognito window
• Start browsing 

Focus on Default Settings

Keep a close eye on your smartphone’s default settings and ensure that they never disclose more information about you without your explicit consent. Most smartphones have encryption settings that can be controlled through the security menu. 

iOS Device

• To check whether your iOS device is private, follow these steps:
• Visit the Settings menu
• Click on Touch ID & Passcode
• You will be asked to enter the screen lock pattern or code
• Go to the bottom of the page that would show data protection is enabled

Android Device

• Ensure your device is at least 80% charged
• Go to security and select the Encrypt phone option 
• Make your smartphone private

Database activity monitoring is no longer a mere compliance checklist, but rather the last line of defense when the perimeter has already been breached. In fact, a report by Verizon revealed that around 30% of the breaches included web-app attacks. They are one of the most common ways used by cybercriminals to access organizational databases. After having access, the criminals move fast. Databases have become the most important assets for organizations that comprise customer records, monetary details, and IPs. Do you know what is dangerous? Many organizations do not have comprehensive visibility into what is actually going on inside their databases.

It is worth explaining about database activity monitoring and the solutions designed to fix this rising issue in the near future. Here we will discuss everything about database activity monitoring and how the solutions can help your business in hybrid systems, insider threat identification, and overall compliance. Let’s begin with the basics. 

What is Database Activity Monitoring?

Gartner defined Database Activity Monitoring (DAM) as a suite of tools that are used to support the ability to spot and report the malicious activities, or other suspicious behavior, with less impact on the user operations and productivity. DAM tools support compliance by producing auditable reports for legal requirements like GDPR, HIPAA, SOX, and PCI-DSS. Compared to legacy logging, DAM provides enriched visibility across hybrid environments, supporting security teams’ focus on risks before any incident occurs. 

What to Consider Before Selecting a DAM Solution?

The real world is not organized, and databases are not all cloud-based. Hence, when it comes to selecting a DAM solution for your organization, you should consider more than a solution that logs SQL statements. You should also consider something designed for complication, compliance, and speed pressure. Here are some things to consider:

Deep Activity Visibility 

An effective solution does not just record someone’s query but shows who did it and what data they bypassed, which app they used, if they used elevated privileges, and if it breached the policy. This encompassess SELECTs, INSERTs, schema changes, and admin commands. 

Complex Infrastructure Support

Many organizations still depend on a combination of old systems, on-premises databases, cloud-based services, and containerized apps. Hence, your DAM solution should manage all of it. This implies agent-based and agentless support, wider database protection, and no dependence on a single cloud vendor’s infrastructure. 

Zero Trust Friendly 

Role-based access is the need of the day. Attribute-based, time-limited, and behaviour-informed access reforms are where you should be. The ideal solutions consider these policies directly within the database session without the need for major application redesign. 

Real-time Enforcement and Response

Logs after the incident are of no use. A genuine solution allows you to react right away. This means triggering alerts, hindering logins, or starting SOAR workflows when policies are breached. Inclusion with SIEM and SOAR platforms such as Splunk, Cortex XSOAR, or QRadar is no more optional but expected. 

User Behaviour Analytics

It is not sufficient to get get alert whenever someone queries longer than usual. Hence, effective solutions must monitor behavioural patterns over time. They segregate what is normal and flag deviations that may point to insider threats, hacked accounts, or misused service details. 

Top DAM Solutions for Organizations

The industry of database activity monitoring solutions is saturated with many providers. However, clarity is very rare. Some tools are quick to implement but ineffective when it comes to analytics. Another solutions delve into compliance but lacks flexibility in hybrid ecosystems. Some of the solutions are better in both, but only if your architecture is sufficient. 

IBM Guardium

IBM Guardium delivers real-time visibility into the database activity across complicated, hybrid systems. It backs up structured as well as unstructured data sources and implements access protocols consistently across cloud and on-premises ecosystems. What is unique about this solution is its ability to expand across vast infrastructure while using risk-based analytics to find suspicious patterns. Guardium goes well with solutions like QRadar and Splunk, which help the teams to act rapidly whenever a breach occurs. 

Imperva Data Security Fabric

Imperva’s data activity monitoring is designed for the cybersecurity teams that need robust policy implementation without compromising speed. It tracks data access in real time, bans unauthorized queries, and pushes behavioural profiling to spot the insider risks. The unique thing about this solution is its combination of data discovery, risk analytics, and blocking features within a single solution. It complies with SIEM systems and offers default policies for compliance frameworks such as PCI-DSS, SOX, and GDPR.

Oracle Audit Vault and Database Firewall

Oracle Audit Vault and Database Firewall is a flagship DAM solution for enterprises. It integrates accurate auditing with a network-layer firewall that tracks and blocks SQL traffic before it accesses the database. The core benefit of this tool is its deep integration with the database stack of Oracle, which allows efficient tracking without the intricacy of third-party vendors. The solution supports unified policy imposition and default compliance reporting for frameworks such as SOX, PCI-DSS, and GDPR.

It provides real-time activity monitoring, risk assessment, and policy-based measures in a single platform. The distinguishing feature of this solution is how it automates compliance workflows across vast, fragmented systems. This makes it very beneficial for enterprises under pressure to address audit requirements faster. 

Broadcom Data Loss Prevention

Broadcom solutions include DAM as a part of its larger data protection tactic. Its main benefit is its comprehensive visibility across endpoints, networks, and databases, which allows the teams to map out the insider threats with database access patterns. Compared to the individual DAM solutions, Broadcom’s Symantec tool emphasizes finding policy violations associated with sensitive data exploitation. It also facilitates strong categorization and incident response. It integrates well with risk analytics and orchestration tools. Overall, these features make it a preferable option for companies involved in broader DLP strategies. 

Thales CipherTrust Data Security Platform 

Thales delivers strong database activity monitoring through its CipherTrust Platform, designed for data-at-rest security across both hybrid and multi-cloud ecosystems. It offers detailed auditing, real-time alerts, and an access log for structured databases without the need for immediate logging. 

The most striking fact is its emphasis on data-centric encryption, together with tokenization, security, and access controls in a single approach. It supports adherence to GDPR, HIPAA, and PCI-DSS and blends well with organizational SIEM tools. You can also read these essential cybersecurity solutions to manage the risks.

There has been an increasing number of attacks targeting users in their web browsers recently. Browser risks cause severe security risks, exposing users to vulnerabilities such as scripting exploits, harmful redirects, malware injections, and other risks. These browser-based attacks compromise credentials, steal personal data, or hinder website integrity. Considering this, the present article explores the browser-based attacks and why they have been increasing recently. This article will also cover how these security risks can be reduced. 

What is a Browser-based Attack?’

Mostly, invaders do not think of themselves as targeting your web browser. Their ultimate goal is to impact your business applications and data. This means targeting third-party services that are now heart of business IT. The most common attack strategy presently finds invaders log into third-party services, use the data, and monetize it through extortion. You can recent recent Salesloft data breaches and other Salesforce attacks to find the consequences. 

The most effective way to do this is by targeting those who use the apps. And due to the changes to the working practices, your users are more accessible than ever before to the external invaders. The customers are also exposed to a wider range of potential attacks. 

Previously, email was the main communication platform with the broader audience, and work happened locally- on your device and within your secured network environment. This made email and the endpoint a higher priority from a security point of view. However, presently, the modern work going on across a network of decentralized internet apps and more varied communication channels, apart from email, makes it difficult to prevent users from engaging with malicious content. Considering the fact that the browser is a place where business apps are accessed and used, it is obvious that attackers will target there too. 

Exploitation of Vulnerabilities 

Exploits are weaknesses in browser code or design that are used by attackers. No browser is entirely immune to the attacks. Security flaws are there, which makes updates the most important. Even commonly used browsers such as Chrome and Edge need regular patches to fix threats. The open web also allows cyber attackers to cause cyber threats, and this increases the need for strong security mechanisms. 

Several browser attacks exploit technical vulnerabilities in browser architecture and implementation. Browsers may lag behind in finding unsafe websites, they allow access to unsafe plugin repositories, or allow harmful extensions. Web applications may also include unpatched vulnerabilities, which make the login portal unsafe. 

Public-facing apps are common targets for exploitation, especially if they have unpatched vulnerabilities or fragile security measures. Companies can also increase the risks of browser-based attacks through unsafe web practices. They often fail to scan downloads for viruses. You can try these strategies to secure yourself from new types of malware. Security teams may not check new services properly or lag behind in monitoring th device or app usage. This leaves room for the attackers. 

Risky user behaviour is another important browser security concern. For example, workers may not understand the risks associated with the unsolicited email attachments or included links. They may download files from strange sources or use the password on different web services. Third parties can also be exposed to security risks through corrupted scripts, fragile security, or old software. Criminals exploit vulnerabilities in externally sourced services to induce malicious code or steal data. Ineffectively secured APIs, third-party plugins, and content management systems can also cause cyber risks to the browsers. 

Key Browser-based Attacks that You Must Know

Phishing for Credentials and Sessions

The most common way for the attackers to harm the business app is to phish a user of the app. You may not necessarily think of phishing as a browser-based attack, but that is exactly in reality today. Phishing tools and infrastructure have changed a lot in the past. The changes in IT mean there are several vectors for phishing attack delivery and apps to target. 

Attackers can share links through instant messaging apps, social media, SMS, and malicious ads, and use the in-app messaging feature and send emails directly from SaaS services to break email-based measures. At the same time, there are now many apps adopted by organizations to target, with different levels of account security configurations. 

Malicious Copy and Paste

One of the challenging security trends in the past year has been the growth of the ClickFix attack technique. It was previously known as Fake CAPTCHA, and the attacks try to fool users into running harmful commands on their devices. This is generally done by resolving the verification task in the browser. 

Practically, by solving the riddle, the users are actually copying malicious code from the clipboard and running it on their device. It generally informs the users that clicking prompts or copying them and running commands can result in cyber attacks. Such attacks are being utilized to deliver infostealer malware, using theft session cookies and details to access the business applications and services. 

Malicious OAuth Integrations

Malicious OAuth integrations are another significant way for attackers to impact an app by fooling a user into authorizing an integration with a harmful, trapped app. This is mainly called consent phishing. It is an effective way for the attackers to decode the authentication and access measures by sidestepping the usual login process to control the account. This includes phishing-resistant multi-factor authentication methods, such as passkeys, as the standard login process is not used. 

Malicious Browser Extensions

Harmful browser extensions are another way used by the attackers to hack your business applications by noticing and capturing logins as they occur, and stealing session cookies and credentials saved in the browser cache and password manager. 

Attackers conduct this attack by creating their own insidious extension and fooling your users into installing it or controlling an existing extension to get access to the browsers. It is quite easy for the criminals to purchase and inject malicious updates into the already-existing extensions and easily bypass the security measures. 

How to Prevent Browser-based Attacks?

Browser-based attacks are continuously advancing, which makes strong security measures very important. Customer browsers have security gaps that are used by attackers. Businesses, thus, should implement a comprehensive approach to minimize the risks. Here are some of the key ways to prevent browser-based attacks:

Patch browsers and extensions: Unpatched browsers cause security concerns. Hence, it is important to use patches to secure the browsers. 

Use safe web pages: Safe websites have HTTPS before the actual name, and they use a padlock symbol in the browser address bar. 

Maintain secure websites: Companies should protect websites against common browser attacks and threats. For this, you can implement secure coding techniques to create web assets. 

Use safe browsing tools: Chrome and Mozilla have security features like Incognito Mode. However, you should always consider safe browser extensions that protect traffic, sort out content, and scan for viruses.

Recently, a consortium of academics from ETH Zurich and Google has found a new type of RowHammer attack focusing on Double Data Rate 5 (DDR5) memory chips from South Korean semiconductor vendor SK Hynix. The Phoenix RowHammer Attack has the potential to bypass strong, modern protection mechanisms adopted to prevent the attacks. 

ETH Zurich reported that triggering RowHammer bit flips on DDR5 devices from SK Hynix is possible on a greater scale. They have also proved that on-die ESS does not prevent RowHammer and thus, the end-to-end attacks are still possible with DDR5. Here, I will discuss everything about the Phoenix RowHammer Attack and its potential impact. 

What is the Phoenix RowHammer Attack?

RowHammer is essentially a hardware vulnerability that allows multiple accesses to a row of memory in a DRAM chip to cause bit flips in adjacent rows. This results in data corruption, which can be used as a weapon by bad actors to acquire unauthorized access to data. Unsurprisingly, it escalates privileges and even results in denial of service. 

Although first shown in 2014, future DRAM chips are likely prone to RowHammer attacks as DRAM producers rely on density scaling to boost DRAM capacity. Reportedly, in 2020, it was found that ‘latest DRAM chips are more prone to RowHammer because as device feature size reduces, the number of activations required to trigger a RowHammer bit flip also decreases. 

More research in this subject has show that the vulnerability has many parameters and that it is sensitive to multiple variables, including environmental conditions, process variation, stored data patterns, memory access patterns, and memory control policies. 

What are the Mitigations for the Phoenix RowHammer Attack?

Some of the major mitigations for Phoenix RowHammer Attack include Error Correction Code and Target Row Refresh. However, these countermeasures have been proven ineffective against the advanced attacks like TRRespass, SMASH, Half-Double, and Blacksmith. 

The recent findings from ETH Zurich and Google revealed that bypassing sophisticated TRR fences is possible on DDR5 memory. This opens the door for what the researchers refer to as ‘the first-ever Row-Hammer privilege escalation exploit on a standard, production-grade desktop system equipped with DDR5 memory’. 

In simple terms, the end result is a privilege escalation exploit that acquires root on a DDR5 system with default settings in as less as 109 seconds. More importantly, the Phoenix RowHammer Attack benefits from the fact that mitigation does not sample some refresh intervals to flip bits on all 15 DDR 5 memory chips in the test pool, which were generated between 2021 and 2024. You can gain more knowledge on DDR5 here. 

Significant exploitation scenarios include such bit flips, allowing for focusing on RSA-2048 Keys of a co-located virtual machine to bypass SSH authentication and using the Sudo binary to increase the local privileges to root user. 

What’s the Recommendation?

As DRAM devices in the wild cannot be updated, they will continue to be vulnerable for several years. Hence, the researchers recommend increasing the refresh rate by 3x, which can stop Phoenix from affecting bit flips on the test systems. After the research teams explained two different Phoenix RowHammer Attacks, the disclosure was made by teams from George Mason University and the Georgia Institute of Technology, named OneFlip and ECC.fail. 

Although OneFlip causes a trigger to a single bit flip, changing Deep Neural Network mode weights and triggering unintended behavior, ECC.fail is defined as the first end-to-end Phoenix RowHammer Attack, which is strong against DDR5 server machines with ECC memory. 

The researchers also reveal that servers have additional security against memory data corruption, such as error-correcting codes, unlike their PC counterparts. These can spot bit flips in memory and significantly correct them. ECC.fail circumvents these security measures by intentionally triggering RowHammer bit flips at specific memory locations. To learn more about prevention measures, you can read on ‘how to prevent ransomware attacks’. 

Challenges with RowHammer Attack Assessment

Addressing RowHammer attacks requires developing something that is difficult for an attacker to trigger bit flips from software. Hence, for effective mitigation, we should realize how a determined adversary launches memory accesses that break existing mechanisms. Three main information components can help with such an assessment:

• How do the improved TRR and in-DRAM ECC work?
• How do memory access patterns from software change in low-level DDR prompts?
• How do any mitigations like ECC or TRR work?

The initial step is mainly difficult and includes reverse-engineering the proprietary in-DRAM TRR mechanism that depends on different manufacturers and device models. You can understand reverse engineering more with this framework. This process needs the ability to issue specific DDR commands to DRAM and analyse its responses, which is problematic on an off-the-shelf system. Hence, specialised evaluation tools are crucial. 

The second and third steps include the evaluation of the DDR traffic between the host processor and DRAM. This could be done with the help of an off-the-shelf interpose, a tool that stays between the processor and DRAM. A critical part of this evaluation is understanding how a live system converts software-level memory access into the DDR protocol. 

The final step is the evaluation of host-side mitigations, which is often optional. For instance, host-side ECC is activated by default on servers, while host-side TRR has only been adopted in certain CPUs. 

RowHammer Testing Platforms 

DDR5 RDIMM Platform

A new DDR5 Tester board to address the hardware needs of Registered DIMM (RDIMM) memory, usual found in server systems 

SO-DIMM Platform

A version which backs the standard SO-DIMM pinout suitable for off-the-shelf DDR5 SO-DIMM memory sticks, general in workstations and end-user devices.

What Lessons Can Be Learned?

It can be understood that present prevention mechanisms for Phoenix RowHammer attacks are not enough, and the issue continues to be a common problem across the industry. They make it more challenging but not impossible to conduct the malicious attacks, as the attacks need a detailed understanding of the particular memory subsystem structure they want to target. 

Current mitigation strategies, dependent on TRR and ECC, depend on probabilistic countermeasures that are not sufficient. After understanding how TRR works, analysts can develop particular memory access patterns to decode it. Moreover, the existing ECC architecture was not developed as a security measure and is thus inefficient in finding errors. 

Memory encryption could be used alternatively for RowHammer attacks. However, the present evaluation is that it does not offer any major defense against RowHammer without cryptographic integrity. Hence, further research is required to find a practical solution.
