WannaCry Ransomware Attack

The WannaCry ransomware attack in May 2017 was a global cyber event where malicious software infected computers running older versions of Windows. It encrypted files on infected systems, making them inaccessible, and demanded ransom payments in Bitcoin for data recovery. The malware exploited a security vulnerability developed by the NSA and leaked by hackers, allowing it to spread rapidly across networks, including hospitals, businesses, and governments. The attack highlighted the importance of regular software updates and cybersecurity vigilance, as many affected organizations faced significant data loss and operational disruptions.
