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 Safari Child Shell Spawn (macOS)
Expected signal: Process launch event showing bash or osascript spawned in temporal proximity to Safari process activity; macOS Unified Log entries capturing both process starts
- Test 2WebKit Process Crash Simulation (macOS)
Expected signal: Crash report generated in ~/Library/Logs/DiagnosticReports/ for safaridriver; macOS Unified Log capturing SIGABRT receipt; endpoint EDR (CrowdStrike/Defender) process termination event with abnormal exit code
- Test 3Suspicious Outbound Connection from Safari Process (macOS)
Expected signal: Network connection event logged by endpoint EDR showing outbound TCP to port 4444 from curl process with Safari user-agent; DNS or network flow records capturing the connection attempt
