The detection rule titled 'Bad Opsec Defaults Sacrificial Processes With Improper Arguments' is designed to identify malicious behavior where attackers utilize processes with poor operational security (OpSec) configurations. This technique often involves the spawning of a sacrificial process, which is a benign process that can be leveraged to execute additional malicious capabilities without alerting security systems. Common examples include invoking processes such as 'rundll32.exe', 'WerFault', 'regsvcs.exe', and 'regasm.exe' without appropriate command-line arguments, making them common targets for exploits. The rule leverages the lack of command-line arguments as a signature for identifying such operations, thereby allowing defenders to spot potentially nefarious activity. The focus is on detecting instances where these processes are executed without the contextual commands usually associated with legitimate use, helping to uncover attempts to bypass security measures during live attacks. The rule examines process creation activity through extensive filtering based on command line and parent image parameters, allowing it to differentiate between legitimate and suspicious execution of these processes. Overall, this detection logic aims to mitigate risks posed by attackers exploiting default process behaviors in Windows environments.
