Who Are Cybercriminals? 

Cybercriminals can be individuals or organized teams who exploit technology to commit illegal acts. Many operate on the "dark web," where they sell illegal services or goods.

Not all hackers are criminals; some, known as "white-hat hackers," use their skills to help organizations identify and fix vulnerabilities. However, those who hack for malicious purposes are called "black-hat hackers" or cyber criminals. 

Cybercrime Categories

The following are the primary categories of cyber crimes 

10 Types of Cybercrime 

The following are the different types of cybercrime that happen all over the world 

1. DDoS Attacks   

A distributed denial-of-service (DDoS) attack involves multiple compromised devices (usually forming a botnet) overwhelming a target server, network, or website with excessive traffic. The objective is to deplete the target’s resources, making it slow, crash, or become inaccessible. This is akin to overcrowding the entrance to a building, so no one can enter or leave.  

2. Hacking 

The hacker is in many ways the archetypal 21st Century criminal, using technology as a means of gaining unauthorized access to private computer systems, frequently for the purpose of obtaining confidential information or perpetrating some kind of fraud. 

3. Botnets   

Botnets are networks of compromised computers controlled remotely by hackers, often for sending spam or launching attacks on other systems. These networks can also function as malware to perform additional harmful tasks on behalf of cybercriminals. 

4. Identity Theft   

Identity theft occurs when criminals obtain personal information to steal funds, access confidential data, or commit fraud. They may open accounts, file fraudulent claims, or execute other illegal actions using stolen credentials, which are often acquired via hacking, social media, or phishing scams. 

5. Cyberstalking   

Cyberstalking involves persistent harassment, threats, or intimidation via online channels such as social media or email. Unlike traditional stalking, it can be carried out anonymously, making it difficult to trace. Common actions include sending abusive messages, spreading false rumors, tracking online activity and many others 

6. Social Engineering   

Social engineering is a technique where criminals contact individuals, often pretending to be customer service agents, to gain trust and extract sensitive information like passwords or bank details. Cybercriminals frequently use details gathered online to enhance their credibility, sometimes by befriending the target on social media. 

7. PUPs (Potentially Unwanted Programs)   

Potentially unwanted programs are a form of low-risk malware that can uninstall essential software, alter settings, or include spyware/adware. They typically compromise system performance and privacy, so using antivirus software is advisable for protection. 

8. Phishing   

In phishing attacks, cybercriminals impersonate trusted entities to deceive people into sharing sensitive data like passwords and credit card details. These schemes typically use deceptive emails, messages, or fake websites that appear legitimate to gain access to personal information. 

9. Prohibited/Illegal Content   

This involves the distribution of illegal or distressing content, including violent acts, sexual exploitation, or materials promoting terrorism. This type of content circulates both on mainstream internet sites and the dark web. 

10. Online Scams   

Online scams typically come in the form of enticing ads or emails promising unrealistic rewards. Clicking these links can lead to malware downloads, compromising the user’s information or system security. 

11. Exploit Kits   

Exploit kits are tools that capitalize on software vulnerabilities to take control of a user’s computer. These kits are frequently sold on dark web forums and are updated like regular software to exploit new weaknesses. 

12. Ransomware Attacks   

In ransomware attacks, malicious software encrypts a victim’s files, making them inaccessible. Cybercriminals demand payment, usually in cryptocurrency, in exchange for a decryption key. These attacks can cause severe financial loss, data loss, and reputational damage to organizations. 

13. Dissemination of viruses  

Most of us are familiar with the problem of viruses, i.e. code that is usually disseminated by email and which will cause a computer to perform specific functions, some harmless (e.g. making bouncing sheep appear on the screen), others less so (e.g. wiping databases clean of the information ) 

14. Domain name hijacking 

 Domain name hacking hit the headlines in April 2000 when hackers transferred more than 50 companies’ domain names to alternative postal addresses. Although this type of online activity was not new, it received widespread media attention because a number of high-profile companies were hit, including Adidas and Manchester United which affected company revenues as well as public confidence. 

15. Misuse of credit cards  

There is estimated to be around £4 billion lost to credit card fraud each year; only 2% of all credit card transactions are currently transacted online, but they are said to account for 50% of these losses. As online trade continues to snowball, it can readily be appreciated that this is a massive problem that is only going to get bigger 

16. Blackmail  

The Internet represents a major opportunity for a determined blackmailer, in that the information that the victim wishes to be kept secret can be quickly, effortlessly, and with relative or even complete anonymity disseminated into the public domain. Even if the victim complies with the demands of the blackmailer the information is still disseminated in public through the internet. 

17. Money laundering 

 Money laundering is the means used by criminals to disguise the origins of the proceeds of their criminal activities. In a non-face-to-face environment and also, due to the extensive use of automated processes (for example, with online stock broking or many online gambling sites), there is reduced opportunity to identify suspicious transactions.  

18. Cyber terrorism  

In the wake of 9/11, there has been greater visibility of the potential of the Internet as a tool for terrorism, not simply as a means of disseminating information but also as an offensive weapon. Terrorists have, for example, been reported to have been exploring ways of hacking into the systems controlling major dams, to see if the gates to the dams would be opened to cause massive flooding. 

Why Are Cybercrimes Increasing? 

The rise of technology and online connectivity has made it easier for cybercriminals to exploit vulnerable systems. Factors like insufficient security, financial motivation, and the complexity of tracing online crimes contribute to the growth of cybercrimes. 

Cybercrime has been on a sharp rise in recent years, impacting individuals, businesses, and governments worldwide. According to recent studies, cybercrime is expected to cost the global economy over $10 trillion annually by 2025, making it one of the largest threats to global security.

Ransomware attacks alone surged by nearly 105% from 2020 to 2021, with businesses facing average downtimes of 21 days following an attack. Data breaches are equally concerning, with over 15 million records exposed in the first quarter of 2023 alone.

The growing prevalence of cybercrime underscores the need for robust cybersecurity measures and heightened vigilance across all sectors. 

Here are some key reasons behind the rising number of cybercrimes: 

● Insufficient security measures leave many devices unprotected, making them easy targets for cybercriminals. 

● Some cybercriminals engage in malicious activities out of personal grievances, using cyberattacks as a form of revenge or to harm individuals they hold a grudge against. 

● The primary driver for most cybercrimes is profit, with hacker groups and individuals often carrying out attacks for monetary gain. 

How to Prevent Cybercrimes 

Preventing cybercrime requires a combination of strong security practices, education, and technology. Here are some effective measures to protect against cybercrime: 

1. Use Strong Passwords and Two-Factor Authentication (2FA)   

2. Keep Software Updated   

3. Install Reliable Security Software   

4. Be Cautious with Emails and Links   

5. Secure Your Wi-Fi Network using Virtual Private Network (VPN)

6. Educate Yourself and Others about cyber threats.

7. Regularly Back Up Data   

8. Limit Access to Sensitive Information   

9. Monitor Your Financial Statements   

10. Report Cybercrime Incidents    

By implementing these practices, individuals and organizations can significantly reduce their vulnerability to cybercrime.  

Top Real-world Cyber Crimes Examples 

Here are some well-known real-life cases of cybercrime:
