Transmission BitTorrent App Contained Malware (cnbc.com)
An anonymous reader writes: Apple users were targeted in the first known Mac ransomware campaign. Hackers targeted Transmission, which is one of the most popular Mac applications used to download software, videos, music, and other data from the BitTorrent peer-to-peer information sharing network. As per this forum post (English screenshot of warning), OS X detected malware called OSX.KeRanger.A. This is the first one in the wild that is functional as it encrypts your files and seeks a ransom. An Apple representative said the company had taken steps over the weekend to prevent attacks by revoking a digital certificate from a legitimate Apple developer that enabled the rogue software to install on Macs.
In fact, in this case probably it was the contrary. I guess the developer was not part of the developer team for transmission, but external. If it were easy to package software for macs without having to pay lots of fees, the dev team could have done it themselves. Apple really should give free dev licenses to free software developers, to help fight abuse. Github does something like that too.
