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.
