Researchers from Palo Alto Networks confirmed to Reuters on Sunday that the ransomware called KeRanger had been discovered in a BitTorrent installer for software called Transmission, a video, music and software peer-to-peer download network. The software affects OS X, apple’s latest operating system.
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.
Palo Alto researchers Claud Xiao and Jin Chen, writing in a blog said: “On March 4, we detected that the Transmission BitTorrent ailient installer for OS X was infected with ransomware, just a few hours after installers were initially posted.”
The ransomware is programmed to activate three days after infection, meaning users who downloaded the virus will be hit today, 7 March.
Apple has now revoked the abused certificate and updated its antivirus signature after it was alerted to the attack.
