How To Downloaded HandBrake On Mac

HandBrake video transcoder is a free tool which converts video from nearly any format to a selection of modern, widely supported codecs for Mac.  It is very popular and has a user-friendly interface.

But the company’s reputation has taken a toll as several installation files of this app have been infiltrated by Trojans, according to the owners.


Yes, you heard it correctly! If you have downloaded HandBrake between May 2 to May 6, your Mac might be infected with a version of OSX.PROTON trojan malware.

HandBrake’s creators said: “Anyone who installed HandBrake for Mac needs to verify their system is not infected with a Trojan. You have a 50/50 chance if you’ve downloaded HandBrake during this period.”

OSX.Proton is a Trojan horse that opens a back door, steals  important information, and downloads potentially malicious files onto the compromised computer. Moreover, it can send screenshots of your system to the hackers. It has potential to let the hacker take over the machine as well.

How to check: If You Are Infected

To know whether your Mac is infected, open the OS X Activity Monitor. Check for a process named “activity_agent” if you find it then, you’re infected.


Similarly, go to the Downloads folder, search for  HandBrake.dmg file. If you get the below checksums, in case, your system is hacked:

SHA1: 0935a43ca90c6c419a49e4f8f1d75e68cd70b274
