If you recently downloaded the HandBrake app for Mac, then there’s a good chance your system is infected with a nasty Remote Access Trojan (RAT).
On Saturday, the HandBrake team posted a security alert after learning one of the mirror download servers was hacked. The attacker replaced the Mac version of the HandBrake client with a malicious version.
In case you don’t know, HandBrake is an open source video transcoder app which allows users to convert video to other formats.
The HandBrake team said an attacker compromised the download mirror server at download.handbrake.fr and replaced the HandBrake-1.0.7.dmg installer file with a version infected with a new variant of the Proton RAT.
