The 2.90 OSX client is compromised, front page (https://www.transmissionbt.com/) states... Read Immediately!!!! Everyone running 2.90 on OS X should immediately upgrade to and run 2.92, as they may have downloaded a malware-infected file. This new version will make sure that the “OSX.KeRanger.A” ransomware (more information available here) is correctly removed from your computer. Users of 2.91 should also immediately upgrade to and run 2.92. Even though 2.91 was never infected, it did not automatically remove the malware-infected file.

(In reply to Neil from comment #1) I have been following that saga over the weekend. As far as I can tell, only the Mac binary package was affected. The source tarball used by Gentoo was not tampered with.
