The Locky virus, a new ransomware that encrypts users’ files and demands bitcoin payments to decrypt them, made an impressive debut Tuesday when it was discovered.
The ransomware attack, which was first sent to nearly half a million victims on February 16, came in the form of a Word document with a malicious macro in it. Targets were sent the infected document via an email
, which led them to believe the document was an invoice requiring payment. When the document was opened, it requested permission to run a Macro, which many victims allowed. The infected macro then performed the dirty work of installing the ransomware and scrambling the victims’ files.
Hollywood Presbyterian Medical Center made headlines this week after it paid $17,000 to ransomware attackers to restore and decrypt files the malware took captive.
