Security researchers have discovered a new piece of **Mac malware;** however, some of its purpose and full features will remain a mystery for a little longer.

Named **Tarmac** (OSX/Tarmac), this new malware was distributed to macOS users via online malvertising (malicious ads) campaigns.

These malicious ads ran rogue code inside a Mac user's browser to redirect the would-be victim to sites showing popups peddling software updates -- usually for Adobe's Flash Player.

Victims who fell for this trick and downloaded the Flash Player update would end up installing a malware duo on their systems -- first the [OSX/Shlayer malware](https://www.intego.com/mac-security-blog/osxshlayer-new-mac-malware-comes-out-of-its-shell/), and then OSX/Tarmac, launched by the first.

**Distributed Since January 2019**

This malvertising campaign distributing the Shlayer+Tarmac combo started in January this year, according to **Taha Karim**, a security researcher at **Confiant**.
