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 1WebLogic WSAT Endpoint Probe
Expected signal: HTTP GET request logged in WebLogic access.log to /wls-wsat/CoordinatorPortType from attacker IP on port 7001. Network flow data showing connection to WebLogic port.
- Test 2WebLogic Async Servlet POST Probe
Expected signal: HTTP POST to /_async/AsyncResponseService visible in WebLogic access logs and network proxy logs. Process audit logs may show WebLogic JVM processing the request.
- Test 3WebLogic UDDI Explorer SSRF Probe
Expected signal: HTTP GET request to /uddiexplorer/ path logged in WebLogic access log. If SSRF is active, outbound connection attempt from WebLogic server to 127.0.0.1:22 visible in network monitoring.
- Test 4WebLogic Admin Console Access Attempt
Expected signal: HTTP GET to /console/login/LoginForm.jsp in WebLogic access logs. Windows Security event logs may show network logon attempts if authentication is attempted. Network flow logs capture the connection.
