The 'Unusually Long Command Line' analytic serves to detect potentially malicious activities indicated by command lines that are notably longer than normal. This is crucial as attackers typically utilize complex command lines to hide their operations and circumvent detection tools. The detection mechanism relies on data from Endpoint Detection and Response (EDR) agents, specifically focusing on the length of command lines executed across hosts. The analysis involves calculating the average and standard deviation of command line lengths per destination and user, establishing thresholds for what constitutes an 'unusually long' command line. Such behavior could lead to serious security incidents like data leakage or ransomware attacks, thus necessitating in-depth investigation of the command's origin, its parameters, and any associated processes.
