Potential Provlaunch.EXE Binary Proxy Execution Abuse

Sigma Rules

View Source
Summary
The detection rule targets the potential abuse of the `provlaunch.exe` binary, which is related to Windows process creation. It focuses on monitoring child processes spawned by `provlaunch.exe`. Since this executable can be leveraged by attackers to execute malicious scripts or applications with elevated privileges, the rule captures unusual activity that may indicate an attempted execution of commonly used binaries like `calc.exe`, `cmd.exe`, `powershell.exe`, etc., when initiated from `provlaunch.exe`. The rule employs specific filters to exclude known good contexts, reducing false positives and enhancing the reliability of the detection. The intent is to identify potential malicious behavior, helping organizations detect attacks that might evade common security measures through proxy execution techniques.
