Turla Group Lateral Movement and Discovery Commands
This rule detects specific command-line activities associated with the Turla APT group's lateral movement and discovery tactics. It looks for the use of 'net use' to connect to administrative shares (specifically C$) with a hardcoded password, and 'dir' commands used for file and directory discovery, targeting document files and executables in the TEMP directory. These commands are indicative of an adversary attempting to move laterally within a network and gather information about the environment.
