Suspicious Commands from CISA Living off the Land Report
This rule detects suspicious command-line executions on Windows systems, as identified in a CISA 'Living off the Land' report. The rule looks for specific patterns in process command lines that, while potentially benign in isolation, could indicate reconnaissance, lateral movement, or data staging activities when observed in concert. Examples include the use of 7-Zip for archiving with a password, specific `pcwrun.exe` or `rar.exe` commands, `ping` commands with unusual parameters or output redirection, `dir` commands targeting network shares, `wmic` commands for process creation or `whoami` execution, `net use` commands for IPC shares, `xcopy` for data movement, and PowerShell commands to launch hidden batch files.
