Previewed at WWDC, launching in the fall.
First Mac Ransomware Found in Transmission BitTorrent Client
This weekend, a notice appeared on Transmissionbt.com warning users that version 2.90 of the popular Mac BitTorrent client downloaded from their site may have been infected with malware. The warning reads:
Everyone running 2.90 on OS X should immediately upgrade to 2.91 or delete their copy of 2.90, as they may have downloaded a malware-infected file.Reuters reports that the infected download contained the first "Ransomware" found on the Mac platform. Ransomware is a type of malware that encrypts a user's hard drive and demands payment in order to unencrypt it. This type of attack has been increasingly popular on the PC, but this is the first time it has been seen on the Mac.
Using “Activity Monitor” preinstalled in OS X, check whether any process named “kernel_service” is running. If so, double check the process, choose the “Open Files and Ports” and check whether there is a file name like “/Users//Library/kernel_service”. If so, the process is KeRanger’s main process. We suggest terminating it with “Quit -> Force Quit”
According to Reuters, Apple is aware of the issue and has already revoked "a digital certificate from a legitimate Apple developer that enabled the rogue software to install on Macs."
The malware in question is said to delay encrypting the user's hard drive for 3 days, so we may see the first reports of those affected as early as Monday. Transmissionbt.com offers instructions on how to see you are affected (above). If you don't use the Transmission software, there is nothing you need to do at this time.
Update: Technical details about the malware.
Update 2: Transmissionbt.com says version 2.92 of Transmission will actively remove the malware.

to be expected when people use BitTorrent, I have zero sympathy for people who pirate stuff!
Whilst most the time both go hand in hand, BitTorrent is just a method of file transfer and not directly related to piracy.

Cant really blame Apple for data loss if you
(a) Don't make regular backups
(b) Install bit torrent clients (from a website no less) Which have little or no legitimate use other than piracy

Apparently it only affects users who downloaded it off of the website and not those who used the in app update.

Lol, I don't think I've met an even SLIGHTLY savvy computer user (Mac or PC) in the last eight years or so that uses a client other than uTorrent.
Given that ALL torrent apps are free, why would anyone download this????????
Stability and no ads. Never had a problem with Transmission as my default client.

Looks like Apple has updated XProtect for this KeRanger malware already. This is from my xprotect.plist file.

I doubt you know many Mac torrent users then, because Transmission is very popular among Mac users. uTorrent now bundles adware along with their installer, so there is also that.

You must have only met slightly savvy computer users then.

That's worrying. You're encouraged to constantly keep your applications and OS updated, but recently that's becoming troublesome. First with Apple's silent security update disabling wired networks and now this! Worrying year for security this.

Transmission was a pretty good application that didn't have all the junk and spyware uTorrent tries to install. I don't know why a tech savvy user would be using uTorrent, though I guess the same holds true for Transmission now.
