The computer virus that only seemed to affect Windows devices has recently infiltrated macOS systems as well.

The false Adobe Flash Player download hides in the digital folders of macOS in hopes of insidiously infecting the computer even if Gatekeeper is set up, due to the certificate attached to it. In most cases, certificates help Gatekeeper ignore legitimate programs, but can also be used to spread viruses.

This imitation programming is an updated version of Windows’ 2008 Snake virus, an intricately designed malware system that may exist for another decade before it vanishes completely. Random users may not have to worry, however, because Windows computer owners who catch the virus are very specific, singled out by the virus’s creator.

Fortunately, the macOS variant of the harmful software can only be transferred through a file labeled Adobe Flash Player.app.zip. If you’re unsure whether the installer is credible or not, look at the signature and bundle structures. If the name is Addy Symonds and the structures are unusual, steer clear.

For users that don’t catch the signs of illegitimacy, the software will download Adobe Flash Player as expected, but also insert the virus files in the hidden folder of the macOS platform and use Apple’s programming to renew the information if the user tries to discard it.

Along with the Snake virus comes the deactivation code and very recent signing of the certificate, indicating its newness. The certificate has been rejected by Apple upon the discovery that it was in fact a digital virus.

Malwarebytes is a great way to check for hidden malware on your macOS system. If the Snake virus exists, it will show up as OSX.Snake and will be deleted. If your computer has been affected, call your information technology company, change your passwords, and don’t open suspicious emails.

Viruses like this will only show up more often as technology becomes more mainstream, so taking precautionary measures is the best way to protect your devices.
