In today’s digitally interconnected world, the internet has revolutionised how we communicate, conduct business, and access information. However, with these advancements also comes the dark side — cybercrime.
These criminal acts threaten individuals, businesses, and governments worldwide. These deceptive and illegal activities are committed online to gain unauthorised access to sensitive information or financial resources for personal gain.
What Do You Mean by Cyber Crime?
Cybercrime, or computer or internet crime, is the illegal use of technology to conduct criminal activities. These crimes can range from financial fraud, identity theft, and data breaches to hacking, cyberstalking, and cyberbullying. The term “cybercrime” encompasses a wide array of illicit activities, and its definition continues to evolve as technology advances.
Basic Cyber Crime Examples
Now that we’ve addressed questions like “What is cyber crime?” and “What is fraud in cyber crime?” let us look at some of the most widespread forms of cyber crimes.
- Identity Theft: Cybercriminals steal personal information, such as social security numbers or credit card details, to impersonate individuals or commit financial fraud.
- Cyberbullying: Using technology to harass, intimidate, or threaten others, often through social media platforms or messaging apps.
- Online Scams: Various deceptive schemes aimed at tricking individuals into providing sensitive information or transferring money to fraudulent entities.
- Hacking: Unauthorised access to computer systems, networks, or devices with the intent to modify, steal, or delete data.

Classifying Cyber Crimes
Cyber crimes can be classified into three primary categories based on their target:
- Personal Cyber Crimes: These crimes target individuals, including cyberbullying, online harassment, and identity theft.
- Corporate Cyber Crimes: Aimed at businesses and organisations, corporate cyber crimes involve data breaches, intellectual property theft, and financial fraud.
- Government Cyber Crimes: Targeted at government entities, these crimes may include hacking government websites, cyber espionage, and cyberterrorism.

What Are The Top 5 Cyber Crimes?
Here’s a list of the top 5 types of cyber crime cybersecurity professionals must look out for:
Malware plays a central role in cybercrime, as it serves as the primary tool cybercriminals use to carry out malicious activities such as data breaches, ransomware attacks, identity theft, and more, exploiting vulnerabilities in computer systems and networks for illicit purposes.
Phishing in cybercrime is a fraudulent and deceptive technique where attackers use messages, emails, or websites that appear to be from legitimate sources to trick individuals into revealing sensitive information, such as usernames, passwords, credit card details, or other personal data. Phishing aims to steal sensitive information for malicious purposes, such as identity theft, financial fraud, or unauthorised access to accounts and systems.
3. Man-in-the-middle Attack
A man-in-the-middle attack in cyber crime involves a malicious actor secretly intercepting and potentially altering communication between two parties who believe they are directly communicating with each other. The attacker positions themselves between the communicating parties, allowing them to eavesdrop on sensitive information, manipulate data, or even impersonate one or both parties.
4. DDoS Attack
A DDoS (Distributed Denial of Service) attack in cybercrime is a malicious attempt to overwhelm and disrupt the regular operations of a target’s online services, such as websites, servers, or networks, by flooding them with steep traffic from multiple sources. As a result, legitimate users cannot access systems and networks, causing downtime and potential financial losses.
DDoS attacks are often orchestrated using a network of compromised computers, known as a botnet, and can be carried out for various reasons, including extortion, revenge, or activism.
5. Drive-by Downloads Attack
A drive-by downloads attack in cybercrime is a web-based attack where malware is automatically downloaded onto a user’s computer or device without their knowledge or consent when they visit a compromised or malicious website. This attack exploits vulnerabilities in the user’s browser or software to infect their system with malware, often leading to data breaches or unauthorised access to sensitive information.

Why Are Cyber Crimes on the Rise?
The increase in cyber crimes can be attributed to several interconnected factors. As technology advances, so do cybercriminals’ tactics and capabilities.
The following are some key reasons why cyber crimes are on the rise:
- Growing Reliance on Technology: Society’s increasing reliance on technology and the internet has expanded the attack surface for cybercriminals. More people are using computers, smartphones, and other internet-connected devices, providing cybercriminals with a larger pool of potential targets.
- Proliferation of Internet Users: With the global increase in Internet accessibility, more individuals and businesses have come online. This exponential growth in internet users offers cybercriminals a larger pool of potential victims to exploit.
- Anonymity and Global Reach: The internet allows cybercriminals to operate anonymously anywhere. This anonymity makes it difficult for law enforcement to track down and apprehend these perpetrators, providing them impunity.
- Cyber Crime as a Lucrative Industry: Cybercrime has evolved into a highly profitable and organised underground industry. Criminals can make substantial financial gains through ransomware attacks, data breaches, and selling stolen data on the dark web.
- Technological Sophistication: Cyber criminals are becoming increasingly sophisticated in their methods, using advanced techniques and tools to carry out attacks. They continuously adapt to security measures and exploit software, network, and device vulnerabilities.
- Lack of Cybersecurity Awareness: Despite the growing awareness of cyber threats, many individuals and organisations still lack sufficient knowledge about cybersecurity best practices. This lack of awareness leaves them vulnerable to various cyber-attacks.
- Insider Threats: Insider threats, where current or former employees compromise security intentionally or inadvertently, can pose significant risks to organisations and their data.
- State-Sponsored Cyber Attacks: Some cyber crimes are carried out by nation-states for political, economic, or espionage purposes. These state-sponsored attacks can target critical infrastructure, government entities, or private organisations.
- Rise of Cybercrime-as-a-Service (CaaS): Cybercriminals now offer their malicious services as a service model, providing less tech-savvy criminals with ready-made tools and resources to execute attacks.
- Exploiting New Technologies: As new technologies emerge, cyber criminals find innovative ways to exploit them. For example, the rise of Internet of Things (IoT) devices has introduced new vulnerabilities that cyber attackers can target.
- Difficulty in Prosecution: The cross-border nature of cyber crimes can make it challenging to prosecute offenders. Jurisdictional issues and international cooperation barriers can hinder law enforcement efforts.
- Lack of Cybersecurity Regulations: In some regions, the lack of robust cybersecurity regulations and enforcement measures allows cybercriminals to operate relatively easily.

Effects of Cyber Crime
The impact of cybercrime can be far-reaching and devastating for individuals, businesses, and governments:
- Financial Loss: Cyber crimes result in significant financial losses due to stolen funds, fraud, and the cost of recovering from attacks.
- Reputational Damage: Organisations facing data breaches or other cyber attacks may suffer damage to their reputation, leading to a loss of customer trust and loyalty.
- Legal Consequences: Cyber criminals can face legal consequences when caught, but the anonymity of the internet makes identifying and prosecuting them challenging.
- Psychological Effects: Victims of cyberbullying and online harassment can experience emotional distress and psychological trauma.
- National Security Risks: Government and critical infrastructure attacks pose significant security risks, potentially compromising sensitive information or services.
