# OT Control-Loop Threat Hunt – RMM/LotL Detection

> OT Control-Loop Threat Hunt – RMM/LotL Detection is a paid API for AI agents from ot-intel-api.onrender.com, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-15).

Detects control-loop reconnaissance patterns and living-off-the-land/RMM tool abuse from submitted OT/ICS process names and command strings using deterministic keyword matching.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ot-control-loop-threat-hunt-rmm-lotl-detection-a7d47e43
```

Example prompt: I'm seeing these processes running in our OT zone — psexec.exe, mstsc.exe, nmap — and these commands: 'net use \\plc01\admin$, tasklist /svc'. Can you check if any of these look like control-loop recon or RMM tool abuse in an OT environment?

## When to prefer this

Choose this endpoint when you need fast, deterministic (no LLM hallucination risk) detection of RMM tool abuse or living-off-the-land techniques in OT/ICS/SCADA environments. Prefer it over generic EDR or LLM-based analysis when you need reproducible, grounded results tied to published OT threat research (CyberAgentX/AgenticCyOps). Best suited for SOC automation pipelines, alert enrichment, and real-time threat hunting in industrial control system contexts where zone-aware severity (OT always HIGH) matters.

## Known failure modes

- Missing both observed_processes and observed_commands returns a validation error requiring at least one
- More than 40 combined entries triggers a limit error
- Invalid zone value (not OT/IT/DMZ) may be ignored or cause a parameter error
- Commas within individual command strings corrupt parsing due to comma-separated format requirement
- Service cold-start on Render free tier may cause initial latency or timeout
- Payment failure via x402 protocol results in 402 response and no analysis

## How this service works

Flags control-loop recon patterns and living-off-the-land/RMM-tool abuse from caller-submitted process/command observations. Pass observed_processes? and/or observed_commands? (comma-separated, max 40 combined), optional zone (OT/IT/DMZ). Fully deterministic keyword matching, no LLM. Grounded in CyberAgentX and AgenticCyOps (arXiv 2603.09134). ADVISORY ONLY — never executes containment or any network action.

## Output

Returns a structured advisory report listing matched threat indicators per submitted process/command, severity scores (with OT-zone matches always rated HIGH for RMM/LotL hits), identified technique categories (control-loop recon, RMM abuse, LotL), and associated threat context grounded in CyberAgentX/AgenticCyOps research. No containment or network actions are taken — output is advisory only.
