A decade-old Windows malware trojan wormed its way into the macOS ecosystem, complete with a signed (likely stolen) Apple developer certificate. The exploit appears as an Adobe Flash Player installer. Once permission is granted, it hides itself deep inside macOS folders. Its certificate has already been revoked by Apple, but it's good to be aware of your enemies.

According to Fox-IT, Snake, a malware framework that has been infecting Windows software since 2008, and more recently Linux, is now targeting Mac.

Now, Fox-IT has identified a version of Snake targeting Mac OS X.As this version contains debug functionalities and was signed on February 21st, 2017 it is likely that the OS X version of Snake is not yet operational.Fox-IT expects that the attackers using Snake will soon use the Mac OS X variant on targets.

Snakes are dangerous and here's why

Similar to the Dok trojan that we heard about earlier this week, Snake popped up with an authenticated developer certificate, which means the Mac's built-in security system, Gatekeeper, would consider it legit and allow the installation process to complete.

It's important to note that Apple has already revoked this fake or stolen developer certificate, so Gatekeeper will block it. However, there is still a slight chance of someone downloading Snake by accident if they've found it through dubious channels. Malwarebytes explains:

Fortunately, Apple revoked the certificate very quickly, so this particular installer is no further danger unless the user is tricked into downloading it via a method that doesn't mark it with a quarantine flag (such as via most torrent apps).

If the app is opened, it will immediately ask for an admin user password, which is typical behavior for a real Flash installer. If such a password is provided, the behavior continues to be consistent with the real thing.

Interestingly, once the installation is complete, Flash is actually installed on the Mac, making it even more difficult to tell that it's a trojan.

How you can protect yourself against Snake
