What is WannaCry ransomware, and how does it differ from other ransomware variants?
WannaCry ransomware is a type of malicious software that encrypts the files on a computer and demands payment, usually in the form of cryptocurrency, in exchange for the decryption key. It gained widespread attention in May 2017 when it infected hundreds of thousands of computers worldwide.
One of the key differences between WannaCry and other ransomware variants is its use of a vulnerability in the Windows operating system known as EternalBlue, which was allegedly developed by the NSA. This allowed WannaCry to spread rapidly across unpatched systems connected to the internet. Additionally, WannaCry had a kill switch feature that researchers were able to activate, temporarily halting its spread.
Overall, WannaCry’s ability to spread quickly and impact a large number of systems set it apart from other ransomware variants at the time.
