It took many years but now cybercriminals are finally targeting Apple's Mac platform with ransomware. The Verge reports the ransomware was strapped to infected versions of the BitTorrent client app Transmission. The malware is named KeRanger, it encrypts a user's storage disk three days after being installed and demands payment to unlock the data.
Apple moved swiftly to control the ransomware after it was first informed about the issue on March 4th, revoking the certificate it uses, and making it so the infected app will no longer install. The Transmission Project, which makes the open-source app, has also released a new, clean version of its software, and has recommended users upgrade as soon as possible. In the meantime, for those unlucky enough to be hit by a world-first, security experts suggest restoring a Mac system backup from before you were infected.
