Introduction Ransomware, a portmanteau of "ransom" and "software," is a malicious program that encrypts a victim's data or restricts access to their computer system. Perpetrators demand a ransom, often in cryptocurrency, in exchange for the decryption key or to release control over the compromised system. The motives behind ransomware attacks can vary, from financial gain to political or ideological reasons. Ransomware dates back to the late 1980s, with the AIDS Trojan, one of the earliest known instances. Since then, ransomware has evolved significantly, becoming more sophisticated and widespread. Notable historical incidents, such as the WannaCry and NotPetya attacks, have had far-reaching consequences and have spurred increased awareness of the ransomware threat. |
