WannaCry

The WannaCry ransomware attack was a worldwide attack perpetrated by the WannaCry ransomware. WannaCry primarily affected users of the Windows 7 operating system. Like most ransomware, the ransom “note” demanded a payment in Bitcoin to decrypt the data.

Some major organisations to have been hit by the ransomware were the National Health Service (NHS) in the UK, Telefónica in Spain, and Deutsche Bahn in Germany.
