Malware hits Mac

OS X users have been targeted with the first known case of Mac ‘ransomware’ malware. It is found in the Transmission BitTorrent client. Infected versions of the app include ‘KeyRanger’ malware that will maliciously encrypt the user’s hard drive after three days of being installed. The malware then asks for payment to allow the user to decrypt the disk and access their data — the ‘ransom’.
