You can also detect and remove this malware with Malwarebytes Anti-Malware for Mac.В Keep in mind, though, thatВ any files that get encrypted before removal will be lost (unless they have been backed up and the backups are still intact).ДЄlso, keep in mind that this is not the first time that Mac users have been infected following the download of a torrent client, though always in the pastВ such infections have only been adware. This should prevent re-activation of the malware. If you have downloaded the Transmission app recently, you should delete the app and restart your computer. However, it also can result in sending money to the hackers and getting nothing in return, or receiving a key that doesnвЂ™t actually work properly because the ransomware was poorly-written.

In the Windows world, paying the ransom sometimes results in getting a key that can successfully unlock the files.

However, itвЂ™s important to understand that this is an extremely bad idea. Some people may be tempted to pay the ransom to get back their files. However, itвЂ™s important to note that if you have already run the infected copy of Transmission on your Mac, this will not prevent you from opening it againвЂ¦ your Mac will consider it safe at this point, since it has been successfully opened previously.В That meansВ this doesnвЂ™t help users who are already infected and who have a 3-day timer counting down.

This means that new infections should not be possible without an update of the malware.

You must re-open the infected Transmission app in order to re-activate the process.ДЄpple has both added detection of this malware to XProtect and revoked the developer certificate used to sign the malicious copy of Transmission. The kernel_service process will remain running, but if you restart the computer, it does not start back up automatically. Interestingly, there appears to be no persistence mechanism to this malware. This means that your backups, which you would want to keep intact in the event of a ransomware infection, may also fall victim to this malware.

Worse, there is code in the app вЂ“ though unused at this time, according to Xiao вЂ“ in a routine called вЂњ_encrypt_timemachineвЂќ. The fact that this malware will encrypt external drives and connected network volumes means that it could encrypt backups, including Time Machine backups stored on a Time Capsule.

In each folder where files have been encrypted, a file named вЂњREADME_FOR_DECRYPT.txtвЂќ is created, containing instructions for how to pay for a decryption key. According to Xiao, it will encrypt everything in the /Users folder, as well as files having common document extensions found in the /Volumes folder (in other words, files that are on connected external hard drives, servers, etc). The latter of these files contains a timestamp, which is used to identify when 3 days have passed.ДЄfter 3 days, the malware вЂњdetonatesвЂќ and begins encrypting files. This kernel_service process remains running in the background, and creates additional files named. When the app is launched, this file is copied to a file named kernel_service in the user Library folder (which is hidden by default on recent versions of OS X). The modified copy of Transmission includes a file named General.rtf, which is actually an executable file rather than the rich-text document it pretends to be. The infected app was distributed from the official Transmission website, but with a different code signature than the normal one previously used to sign the Transmission app, implying that the app itself had been modified and re-signed by the attacker (although this has not yet been confirmed).

ItвЂ™s in the wild.ДЄccording to Xiao, the Transmission app вЂ“ a BitTorrent client вЂ“ was infected to include this ransomware. It was revealed on Sunday by Claud Xiao of Palo Alto Networks that KeRanger is the first real Mac ransomware, and itвЂ™s not just theoretical. Apple quietly added detection of something called вЂњKeRangerвЂќ to the XProtect anti-malware definitions in OS X on Saturday.
