Testing Methodology
Validate this detection against 4 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 1CWP Command Injection via API Parameter
Expected signal: Linux audit log EXECVE event showing 'id' executed by the web server user (www-data/apache/cwp); web access log entry with URL-encoded semicolon in query parameter
- Test 2Reverse Shell Establishment Post-CWP Exploitation
Expected signal: Process creation event for bash spawned by www-data user with -i flag and /dev/tcp redirect; outbound TCP connection to attacker IP on port 4444 from the CWP host
- Test 3Credential Harvesting via /etc/shadow Access
Expected signal: Audit log showing www-data user attempting to read /etc/shadow; base64 encoding command in process arguments; file access event on /etc/shadow
- Test 4Dropper Download via Injected wget Command
Expected signal: wget process spawned by www-data with external URL argument; outbound HTTP GET to attacker-controlled server; file creation event in /tmp by web service user; chmod execution on downloaded file
