NotPetya

NotPetya was a cyberattack in 2017 that targeted computer systems, primarily in Ukraine but also affecting global organizations. It was designed to spread rapidly, encrypting files and making systems unusable, similar to ransomware. However, its true purpose was to cause widespread disruption and damage rather than financial gain. It exploited vulnerabilities in software and used malicious updates to infect networks, which resulted in significant operational and financial losses for affected companies worldwide. NotPetya is considered one of the most destructive cyberattacks due to its speed, scope, and impact on critical infrastructure.
