Sigma Rules
4 rules found for "Swisscom"
MMC Spawning Windows Shell
Detects a Windows command line executable started from MMC
MSHTA Execution with Suspicious File Extensions
Detects execution of mshta.exe with file types that looks like they do not typically represent HTA (HTML Application) content, such as .png, .jpg, .zip, .pdf, and others, which are often polyglots. MSHTA is a legitimate Windows utility for executing HTML Applications containing VBScript or JScript. Threat actors often abuse this lolbin utility to download and execute malicious scripts disguised as benign files or hosted under misleading extensions to evade detection.
Renamed Jusched.EXE Execution
Detects the execution of a renamed "jusched.exe" as seen used by the cobalt group
Potential Renamed Rundll32 Execution
Detects when 'DllRegisterServer' is called in the commandline and the image is not rundll32. This could mean that the 'rundll32' utility has been renamed in order to avoid detection
