FileFix Detection - Browsers Launching Lolbins
This rule detects instances where common web browsers (e.g., Chrome, Edge, Firefox) launch specific Living Off The Land Binaries (LOLBins) or scripting interpreters. The LOLBins and interpreters include `cmd.exe`, `powershell.exe`, `rundll32.exe`, `regsvr32.exe`, `msiexec.exe`, `mshta.exe`, `hh.exe`, `certutil.exe`, and `bitsadmin.exe`. This activity can indicate malicious intent, such as drive-by downloads, exploit kit activity, or initial access attempts where an attacker leverages a browser to execute system utilities for further compromise.
