First Mac Ransomware

Ransomware is no longer just for Windows users. It’s now made its way into the Mac OS. The ransomware called KeRanger, was distributed via a legit and popular BitTorrent client called Transmission.

Users who have downloaded Transmission 2.90 since last Friday are infected. Transmission has removed the malicious version of their software and made a patch. Users should upgrade to version 2.92.

The KeRanger malware imposes a 72 hour lockout window requiring victims to pay 1 bitcoin or equivalent to about $400.
