The “com.apple.4V.plist” file is placed in ~/Library/LaunchAgents by the original dropper and disguised as a Property list configuration file (PLIST) while it is in fact a compiled AppleScript. Straight away, we see that a number of VMRay Threat Identifier (VTI) rules hit and the sample is classified as malicious.

Now we can dig deeper into each of these characteristics. The Network Tab shows multiple C2 connections.
