Detects the execution of binaries located in potentially suspicious locations, specifically within the '/tmp/' directory, using the 'nohup' command. This behavior is often associated with malware attempting to maintain execution even after a user logs off or a session terminates.

This rule detects the execution of the 'grep' command on Linux systems when it is used to search for specific filenames associated with the GobRAT malware. The filenames include 'apached', 'frpc', 'sshd.sh', and 'zone.arm'. This activity indicates that an attacker, potentially using GobRAT, is attempting to discover files related to their malware deployment or persistence mechanisms.
