I just read that Transmission has been infected with malware, for the second time in half a year. I understand it only concerns the version that was downloadable via the website (2.92) which was vulnerable only for a couple of days. The previously infected version was 2.90 (that happened in March).
Also because of these issues I haven't upgraded since version 2.84, which I still use. Actually I'm quite happy with Transmission, it's simple and works fine.
Do you have any thoughts on this, has anyone changed their client because of these security issues or do you still use Transmission and which version?
The malware-infected version of Transmission has a digital signature of Aug. 28, so ESET is advising anyone who downloaded Transmission 2.92 between Aug. 28-29 that their systems might be compromised.
If you think you might be affected, check for the existence of any of these files or directories:
/Applications/Transmission.app/Contents/Resources/License.rtf /Volumes/Transmission/Transmission.app/Contents/Resources/License.rtf $HOME/Library/Application Support/com.apple.iCloud.sync.daemon/icloudsyncd $HOME/Library/Application Support/com.apple.iCloud.sync.daemon/process.id $HOME/Library/LaunchAgents/com.apple.iCloud.sync.daemon.plist /Library/Application Support/com.apple.iCloud.sync.daemon/ $HOME/Library/LaunchAgents/com.geticloud.icloud.photo.plist If you see this stuff, ESET says it means that the malicious version of Transmission was executed and that “Keydnap is most likely running.”
So new downloads will not be affected, as Transmission removed the malware from their servers as soon as they discovered it. If you did download it on the 2 days highlighted above, run the virus scans suggested by gizmodo to get rid of it. There's also a script for advanced users to remove the dodgy files. I always tend to wait a bit before upgrading Transmission because of the last infection (which I thankfully didn't have). In any case, a good virus scanner is always worth having to hand as more cyber criminals try to get through Mac security.
edit: Sophos & ClamXav will detect both Mac & windows viruses, but ClamXav isn't free anymore. Avast will only detect Mac viruses, so my top choice would be Sophos
