Ransomware, a form of malicious software that encrypts files and demands a ransom for decryption, has become a major cybersecurity threat. Its origins can be traced back to the late 1980s with the AIDS Trojan, which targeted AIDS researchers. As the internet became more prevalent, ransomware evolved, with improved encryption algorithms making it harder for victims to recover their files without paying. The emergence of CryptoLocker in 2013 marked a significant milestone, introducing a more sophisticated encryption-based model and the use of Bitcoin for ransom payments. Ransomware-as-a-Service (RaaS) gained traction in 2015, allowing individuals with minimal technical skills to launch attacks using pre-designed malware. Notable ransomware attacks include WannaCry, NotPetya, Ryuk, and Maze. Modern ransomware threats are highly advanced, targeting critical infrastructure and large corporations, and often include features like encryption, data theft, and exfiltration. To combat this growing menace, individuals and organizations must invest in robust cybersecurity measures, regularly backup data, and stay informed about the latest ransomware threats and prevention strategies.
