The team at HandBrake posted a security warning that users who downloaded the application between 2 nd May and 6 th May should scan their machines for the Proton malware. Hackers were able to compromise a download server for HandBrake, a widely used open-source program that is used to rip DVDs and convert video files, and hide malware within it.

If you installed the popular Mac DVD ripper and video converter Handbrake early last month, your machine might be at risk from a backdoor trojan known as Proton.
