Data Sources
Required Tables
False Positives & Tuning
- Triofox server-side processes handling legitimate high-volume file synchronization from many clients
- Authorized Triofox administrative tools performing bulk configuration or user management
- Backup agents running against Triofox storage generating sustained high connection counts
- Triofox internal health monitoring or watchdog processes creating frequent process events

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 1Triofox Unauthenticated Admin Endpoint Probe
Expected signal: IIS access log entries showing GET requests to /api/user/list, /admin/dashboard, /admin/users, /token, /api/settings from the test machine IP without authentication headers. Windows Security Event ID 4625 may appear if the application logs failed authentication attempts.
- Test 2Triofox Token Endpoint Brute Force Simulation
Expected signal: IIS log entries showing 30 POST requests to /token from the test IP within seconds, with HTTP 401 or 200 response codes. Application-level Triofox logs may record authentication attempts.
- Test 3Triofox File Access Path Traversal Probe
Expected signal: Windows Security event logs and IIS access logs recording HTTP GET requests to file-related Triofox endpoints without valid session tokens. Network telemetry in CrowdStrike or EDR showing outbound HTTP connections from the test machine to the Triofox server.
