What is WannaCry Ransomware and what does it do?
The WannaCry ransomware attack started on Friday, May 12, 2017, and is unprecedented in scale, already affected more than 230,000 computers in over 150 countries. So far, the ransomware hit Russia, Ukraine, India, and Taiwan the hardest.
It spreads across local networks and the Internet to systems that did not update with the most recent security updates. It will then encrypt your hard drive and ask for a ransom in Bitcoins to get a decryption key. Most of the time, infected hard drives must be completely wiped to remove the malware and only about 50% of the time are the contents recoverable. This also impacts USBs. It uses software developed by the NSA.
