Testing Methodology
Validate this detection against 3 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1Simulate IE Spawning CMD via Scripted Process Launch
Expected signal: ProcessCreate event with ParentImage=iexplore.exe and Image=cmd.exe visible in Sysmon Event ID 1 and Windows Security Event ID 4688
- Test 2Internet Explorer Spawning PowerShell for Encoded Command Execution
Expected signal: Sysmon Event ID 1: powershell.exe with encoded command and parent iexplore.exe; Network telemetry showing iexplore.exe with an active TCP session at time of child spawn
- Test 3Heap Spray Pattern Simulation via IE Memory Allocation Script
Expected signal: High memory allocation events in iexplore.exe process; potential script engine events logged if Script Block Logging is enabled; browser process memory consumption spike visible in performance telemetry
