Apple Macs targeted by KeRanger ransomware for first time

Experts say some Macs may have their files encrypted on Monday if computer has been infected

Apple customers were targeted by hackers over the weekend in the first campaign against Macintosh computers using a pernicious type of software known as ransomware, researchers with Palo Alto Networks have revealed.

Ransomware, one of the fastest-growing types of cyber threats, encrypts data on infected machines, then typically asks users to pay ransoms in hard-to-trace digital currencies to get an electronic key so they can retrieve their data.
