This blog will let you know about this attack, i.e., the ileakage attack on Apple, how it works, and what you can do to prevent it from compromising your online security. Lets start with iLeakage Attacks.
iLeakage Attacks: What are they?
The fast-paced Digital Age has made access of personal information very easy in various forms. If you are a Mac user, you are secure at every level of cyber threats. But it is alarming that iLeakage attacks can lead to the unauthorized disclosure of sensitive data.
iLeakage attacks are a form of cyberattack that mainly targets Mac users. It exploits a vulnerability in the iCloud service. The attackers use phishing emails or malicious websites to trick the users into entering their iCloud credentials. Once the credentials are captured, accessing the personal data stored on the cloud becomes much more accessible. The attackers can then steal emails, passwords, photos, contacts, documents, and other sensitive information from the victims.
iLeakage attacks refer to the unauthorized leakage of sensitive user data while browsing the internet. These attacks can expose private information such as passwords, credit card details, and personal identification data. Cybercriminals exploit vulnerabilities in web browsers like Safari to extract user information and use it for malicious purposes, including identity theft and financial fraud. As a Safari user, it is crucial to understand the risks associated with iLeakage attacks and take proactive measures to protect your information.
Safari’s vulnerability to iLeakage attacks
Safari, being one of the most popular web browsers globally, is unfortunately not immune to iLeakage attacks. While Apple continuously releases security updates and patches to address vulnerabilities, hackers constantly evolve tactics to bypass these measures. Consequently, Safari users need to stay vigilant and implement additional security measures to safeguard their data.
Types of iLeakage attacks on Mac
Keylogging attacks
Keyloggers are malicious software or hardware that record every keystroke on a computer. These attacks capture usernames, passwords, credit card details, and other sensitive information by monitoring keystrokes. Keyloggers can be installed secretly through email attachments, file downloads, or malicious websites.
Phishing attacks
Phishing attacks involve deceiving users into revealing their personal information. It is by email, messages, or fake websites disguised as legitimate sources. Attackers craft compelling messages or websites that prompt users to enter their credentials or financial details, unknowingly giving away sensitive information.
Malware attacks
Malware, short for malicious software, is designed to infect a computer system, gather sensitive data, or cause damage. Mac users are not invulnerable to malware attacks, contrary to the popular notion that Mac systems are inherently secure.
Man-in-the-middle attacks
In a man-in-the-middle attack, an attacker intercepts communication between two parties, often without their knowledge. The attacker can eavesdrop, modify, or even inject malicious code into the communication, compromising the confidentiality and integrity of the data being exchanged.
Social engineering attacks
Social engineering involves manipulating individuals into divulging confidential information through psychological manipulation or deception. Attackers may pretend as trusted entities, such as tech support personnel, to gain the victim’s trust and extract sensitive information.
Remote code execution attacks
Remote code execution attacks exploit vulnerabilities in software or applications to execute arbitrary code on a target system. This allows attackers to access sensitive data or perform malicious actions on the compromised device.
Zero-day attacks
Zero-day attacks exploit vulnerabilities in software or operating systems that are unknown to the software developers. Attackers take advantage of these undisclosed vulnerabilities before they are patched, leaving users’ devices susceptible to exploitation
iLeakage Attacks: Unveiling the Steps
iLeakage attacks occur when an individual or group gains unauthorized access to private information stored on electronic devices. These attacks can target various devices, including smartphones, tablets, and computers. The attacker aims to extract sensitive data and leak it to unauthorized individuals or organizations. But how do these attacks happen in the first place?
Stage 1: Target Identification
The first step in an iLeakage attack is identifying a potential target. Attackers search for vulnerable individuals or organizations with valuable information stored on their devices. They might exploit weaknesses in security systems or prey on unsuspecting users who inadvertently create opportunities for attack.
Stage 2: Exploiting Vulnerabilities
The next stage involvesexploiting system vulnerabilities. The stage is done by various means, such as malware, phishing, or social engineering techniques. Attackers capitalize on human error or outdated software to breach defenses and gain unauthorized access to the target’s device.
Stage 3: Data Extraction
Once inside the target’s device, the attacker begins extracting sensitive data. This include personal information, financial records, or intellectual property. The attacker may employ advanced techniques to bypass security measures and retrieve the desired data without raising suspicion.
Stage 4: Concealing the Attack
To avoid detection, the attacker must cover their tracks and ensure the iLeakage attack goes unnoticed. They may use encryption methods or disguise their activities to avoid detection by security systems or the target. This allows them to continue extracting data over an extended period, maximizing their gains.
Stage 5: Data Leakage
The final stage of an iLeakage attack involves the unauthorized sharing of extracted data. The attacker may sell the information on the black market or use it for personal gain. This can have devastating consequences for the target, ranging from financial losses to reputational damage.
The Researcher’s Opinion of Safari Attack
The researchers wanted to read secret information from Safari, and they did it by making a tool that can guess and show any 64-bit pointer in the memory area Safari uses to display web pages.
They overcame the security features Apple added to its browser, like low-quality timer, smaller 35-bit addressing, and value poisoning.
The researchers also got past the site isolation policy in Safari, which puts different websites in different memory areas based on their main domain and one subdomain.
They used a new technique that uses the JavaScript window. Open API to let an attacker page share the same memory area as any victim page.
By guessing type confusion to get past Apple’s smaller 35-bit addressing and value-poisoning security features, the researchers could show secret information from the target page, such as passwords and emails.
The code for the attack is in JavaScript and WebAssembly, the two languages for making dynamic web pages.
What are the models of iphone that are targeted or are prone to the ileakage?
According to a report by Palo Alto Networks, all iPhone models are prone to iLeakage attacks. However, the following iPhone models are at an increased risk of iLeakage attacks in 2023 are as follows:
- iPhone 13 Pro and Pro Max
- iPhone 12 Pro and Pro Max
