This rule aims to detect the execution of the "Splwow64.exe" process without any command line parameters, which could indicate suspicious activity or potential malicious behavior. Splwow64.exe is a legitimate Windows system file that is part of the Windows printing subsystem and is responsible for enabling 32-bit applications to communicate with 64-bit printer drivers. However, attackers may exploit this process due to its legitimate status to evade security measures. By monitoring for instances where Splwow64.exe is running without any command line parameters, the rule helps identify such suspicious activity, which may warrant further investigation. The primary detection method involves filtering for the image name ending with "\splwow64.exe" and ensuring that it is executed with an empty command line. Given the high potential for misuse of this process, this rule is classified as high importance in threat detection frameworks, especially for Windows environments.
