Start by defining what constitutes a cybercrime. Cybercrime is any unlawful activity carried out through a computer or other internet-connected technological device. Cybercrime may be committed by lone individuals or small groups of persons with limited technological expertise, as well as by highly organized international criminal organizations with relatively capable developers and specialists.
Most cybercrime cases are committed by hackers or cybercriminals looking to make money. Cybercrime is a problem that affects both individuals and businesses. In addition, cybercriminals may exploit networks or computers to deliver malware, pornographic content, viruses, and other illegal data.
Cybercriminals use a variety of profit-driven criminal activities to acquire money, including identity theft and resale, getting access to bank accounts, and obtaining money by using credit cards fraudulently.
Basic Cybercrime Examples
-
Credit card data that has been stolen:
The most frequent type of cybercrime involves the theft of a person’s credit card information, which is then fraudulently used to obtain or pay for products or services on the internet.
-
Hacking into a government website:
Tampering with private information held by the government is another form of cybercrime.
-
User account theft:
Between 2013 and 2016, Yahoo suffered a massive data breach that led to the loss of three billion user accounts. The attackers were able to get passwords and confidential data used to log into user accounts for other online services. Even today, the dark web still has access to the majority of this data. This case became a historic example of cybercrime.
-
IoT devices
IOT devices that have been compromised is another type of cybercrime: In 2016, approximately one million IoT devices that are linked to the internet have been taken advantage of by hackers. The global DNS experienced disruptions as a result of this, the biggest DDoS assault to date, which also affected several well-known services, including Netflix, PayPal, Twitter, and many more.
-
Loss of control and content access
Ransomware that encrypted user content was released by the WannaCry assault in 2017, which North Korea is suspected of having conducted. Within a short period of time, this malware has infected 300,000 machines globally. To have their data back, the victims had to spend hundreds of dollars. So cybercrime cases not only harm financial positions but it is also an exhausting process to recover the data.
-
Phishing campaigns:
Phishing campaigns utilise fake emails that seem real to fool people in an organisation into doing activities like downloading files or clicking links in order to gain access to company networks. The malware or viruses then propagate to the systems and finally reach the networks of the companies, and after this the process is pretty simple for the hackers to create yet another case of cybercrime.
The selling of illicit commodities like narcotics, weapons, or knockoffs; illegal gambling; the creation, distribution, or possession of child pornography, etc., are some other frequent examples of cybercrime.
How many types of CyberCrime Are There?
There are many different kinds of cybercrime; the most prevalent ones are clickjacking, spyware, email fraud, social media fraud, banking fraud, ransomware attacks, cyber espionage, and identity theft. Let’s see how these cybercrime cases are currently being committed.
-
Malware
Trojans, viruses, and worms are only a few examples of the diverse types of cybercrime that go under the umbrella term “malware.” Malware is basically computer code designed to steal data or obliterate computer components.
We can categorize the sort of virus we are dealing with by looking at how the malicious software harms users.
- Viruses: Viruses attach to clean files and spread to other clean files, just like their biological namesakes. Viruses have the ability to proliferate uncontrolled while corrupting and erasing files as well as harming the system’s basic operation. Typically, executable files acquired via the internet contain viruses.
- Trojan: This kind of malware impersonates hackable, genuine software. It prefers to operate covertly and introduces security backdoors that let more infections into the system.
- Worms: Worms may spread locally or over the internet by infecting a large network of devices over the network interface. With each subsequent infected machine, worms spread to new machines.
-
Phishing
Phishing typically takes the form of a legitimate third party asking for personal information. Users are urged to provide their personal information by clicking on a link in phishing emails.
Some consumers may not be able to discern between a legitimate and fraudulent request for information due to the complexity of phishing emails in recent years. Although phishing emails are occasionally grouped with spam, they are much more harmful than ordinary advertising. As through spams the chances of cybercrime is much higher.
Five steps make up phishing:
- The phisher must decide which company to target and devise a plan for obtaining the email addresses of that company’s clients.
- Preparation: The setup phase may start after the phisher decides which entity to impersonate and who the targets will be. The phisher creates, disseminates, and gathers data through communications. As data is the most important aspect when it comes to cybercrime.
- Execute the attack: Most individuals are familiar with this procedure. A phoney communication that looks to be from a reputable source is sent by the phisher.
- Data collection: The phisher records the data that victims enter into websites or pop-up windows.
- Identity theft and fraud: The phisher utilises the data they have gathered to commit fraud or engage in other nefarious activities; up to 25% of victims never fully recover.
-
Attack by DoS
A denial-of-service (DoS) attack targets interrupting network service, as the name indicates. Attackers flood the network with data traffic, causing it to become overwhelmed and malfunction. A distributed denial-of-service (DDoS) assault is the most popular method of conducting a DoS attack. It entails the attacker using many machines to provide traffic or data that will overload the system.
In many circumstances, a person may not be aware that their computer has been compromised and is aiding the DoS assault. There have been several significant DoS attacks in the past, which can have serious effects on security and internet access. DoS assaults on a wide scale have been used frequently as a single protest against governments.
-
Attack by a Man-in-the-Middle
By pretending to be the endpoints in the online information exchange, a man-in-the-middle attack can get information from the end-user and the entity they are talking with.
The man in the middle would contact the user by posing as the bank if the user was conducting online banking. All information exchanged between the user and the bank, including sensitive information about bank accounts, would be sent to the middleman. And that middleman can easily misuse the data and use it for cybercrime cases.
-
Attack by Drive-by Download
We no longer have to click to accept a download or apply a software update in order to get infected. Now, viewing a hacked webpage might result in the installation of harmful malware on our device. To download malicious malware on our device, we merely need to browse or pass by a website and click the accept button for any program.
A download from these pages may result in the unintended installation of malware or a virus on a computer or mobile device.
Drive-by downloads often take advantage of or exploit a vulnerable operating system, program, or browser that is out of date. And these data have become one of the most commonly used sources of cybercrime.
How Can CyberCrime Be Prevented?
- Back up all information, the system, and other things: As a result, data that was previously preserved can help firms recover from an unexpected incident.
- Maintain current security measures and enforce them: Pick a firewall that offers protection from viruses, malware, and dishonest hackers. Because of this, firms may see dangers earlier and take quicker action. As in tha case of cybercrime, the least time you take to take actions, the better it is.
- Never divulge private information to a stranger since they could exploit it for fraud and eventually it could lead to cybercrime.
- To avoid cybercrime, check your security settings: In order to determine if someone has logged into your computer, a cyber firewall analyses your network settings.
- Using antivirus software can help you identify threats and viruses before they infiltrate a computer system. Never use cracked software since doing so puts your computer at considerable risk for virus infection or data loss or cybercrime aswell.
- Keep your information protected when accessing untrusted websites: Information may readily circumvent the data through phishing websites, as a lot of cases of cybercrime has a source of website data.
- Utilize virtual private networks (VPNs) to cloak your IP address.
- Access restrictions to your most important data: If you can, create a folder to keep private papers hidden. Hiding passwords is one the smartest ways to prevent cybercrime.
