Data Sources
Required Tables
False Positives & Tuning
- Legitimate Triofox desktop clients performing large file synchronization creating burst traffic
- Internal monitoring systems checking Triofox API health endpoints frequently
- Shared egress IPs from organizations with many Triofox users appearing as single high-volume source
- Content delivery or caching systems pre-fetching Triofox resources

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.
