New EvilQuest Mac Ransomware Discovered In Pirated Apps
A new variant of ‘EvilQuest’ ransomware is spreading through pirated Mac apps. According to Malwarebytes, the ransomware was found embedded in the pirated version of the “Little Snitch app” available on a Russian forum.

Although, the installer mimics the original version of Little Snitch however an executable file named “Patch” that will get fixed in “/Users/Shared directory“. Along with that, a post-install script is also installed on the machine.
After which, the Patch file gets moved to a new location by the installation script. Next, it gets renamed as CrashReport, which is a legitimate Mac OS process. However, it hides the process from the Activity Monitor.
Further, the Patch file then installs itself in several locations on the Mac.
The ‘EvilQuest’ Ransomware
The EvilQuest ransomware encrypts the data files along with changing settings on the Mac. As it encrypts the files like Keychain files, as a result the user gets an error while trying to access the iCloud Keychain.
