One notable example was the Michelangelo virus in 1992, which was designed to activate on Michelangelo’s birthday and destroy data on infected computers. Additionally, the emergence of email as a primary communication tool led to the creation of email-based viruses like the Melissa virus in 1999, which spread rapidly by exploiting vulnerabilities in Microsoft Word.

The commercialization of the internet also gave rise to new motivations for cybercriminals, including financial gain and corporate espionage. This period saw the advent of phishing attacks, where attackers would deceive individuals into providing sensitive information, such as passwords and credit card numbers.

The 2000s: The Era of Organized Cybercrime

The early 2000s marked the beginning of a more organized and professional approach to cyber threats. Cybercriminals started forming sophisticated networks and using advanced techniques to carry out large-scale attacks.

This era witnessed the rise of botnets, networks of infected computers controlled by a central command, which were used for various malicious activities, including distributed denial-of-service (DDoS) attacks, spamming, and data theft.

One of the most significant cyber threats of this era was the Mydoom worm in 2004, which became one of the fastest-spreading email worms in history. It was designed to create a backdoor in infected systems, allowing remote control by the attacker.

Another notable incident was the TJX data breach in 2007, where cybercriminals stole over 45 million credit and debit card records from a major retailer.

During this period, state-sponsored cyber espionage also became a significant concern. Countries started using cyber attacks to gather intelligence and disrupt the operations of rival nations. One of the most prominent examples was the Stuxnet worm in 2010, which targeted Iran’s nuclear facilities and caused significant damage to their infrastructure.

The 2010s: The Age of Advanced Persistent Threats (APTs) and Ransomware

The 2010s saw the emergence of Advanced Persistent Threats (APTs), which are prolonged and targeted cyber attacks carried out by well-funded and highly skilled adversaries. APTs are typically used for cyber espionage and are characterized by their ability to remain undetected within a network for extended periods. Notable examples include the APT1 group, believed to be associated with the Chinese military, and their operations targeting various industries to steal intellectual property.

Ransomware also became a prominent threat during this decade. Ransomware attacks involve encrypting a victim’s data and demanding a ransom for the decryption key. One of the most infamous ransomware attacks was WannaCry in 2017, which affected over 230,000 computers in 150 countries. The attack exploited a vulnerability in Microsoft Windows and caused widespread disruption in various sectors, including healthcare and transportation.

Additionally, the rise of social media and mobile devices introduced new attack vectors for cybercriminals. Social engineering attacks, where attackers manipulate individuals into divulging confidential information, became more sophisticated.

Cybercriminals also started targeting mobile devices with malware designed to steal personal information and carry out financial fraud.
