AI Agent Runtime Implant Engine
We implant the agent, not the model. PLANT writes directly into Redis, SQLite, LangGraph, Mem0, and .env — wherever the agent loads its persistent context. HOOK backdoors .mcp.json, CLAUDE.md, and Cursor/Kiro rule files so every future session starts already compromised. BEACON exfiltrates through DNS subdomain encoding, HTTP path encoding, or DeepSeek R1 <think> tokens. SURVIVE plants across all backends simultaneously — remove one, the others heal it back. Zero model weights changed. Zero traces.
Detect agent framework, memory backends, and config attack surface. Live Redis probe across default ports. SQLite scan for agent tables. Filesystem discovery of .mcp.json / CLAUDE.md / .cursorrules / Kiro rules. HTTP probe for LangGraph, Mem0, n8n endpoints. Attack surface scoring and vector recommendation.
Write implant to memory backends. Redis: prepend to existing agent context keys with optional TTL. SQLite: INSERT into messages/memories/checkpoints tables. LangGraph: POST to /threads/{id}/state — survives session rotation. Mem0: POST to /v1/memories/ with user_id targeting. Env: write AGENT_PERSISTENT_CONTEXT to .env file. All backends verify implant after write.
Modify tool/config files for persistent instruction injection. Five vectors: .mcp.json (inject venom-ctx server with VENOM_CONTEXT env var), CLAUDE.md (OPERATIONAL_CONTEXT_v1 block), .cursorrules, .kiro/rules/ (Kiro IDE rule file), tool_registry JSON (insert poisoned get_operational_context tool at position 0). Backup before write, restore support.
Three covert C2 modes. DNS: base32-encode data as subdomain labels, agent performs DNS lookup via its HTTP tool — no firewall blocks DNS. HTTP: base64url-encode in /hc/{encoded} path — agent makes GET to attacker-controlled endpoint. THINK: DeepSeek R1 only — embed [VENOM_EXFIL:DATA=base64] in <think> block. Zero visible output signature.
Multi-layer resilience: plant across all configured backends simultaneously. Integrity monitor checks each backend for implant presence. Self-heal: if any backend cleared, automatically replant from the others. Recovery instruction embedded in the implant itself — the agent becomes complicit in restoring its own compromise. Redundancy level ≥2 recommended.
Design trigger-phrase remote activation. 8 actions: EXFIL_CONTEXT / DUMP_CREDENTIALS / EXECUTE_SHELL / PIVOT / WIPE / BEACON_NOW / SHUTDOWN / REPORT_STATUS. Trigger obfuscation: Cyrillic homoglyphs, zero-width characters, l33t variants, case folding, hash suffix. Generates 7 trigger variants for embedding. No external C2 after implant fires.
Continuous harvest of agent conversations via beacon channel. Four field sets: full (system_prompt + credentials + tool_results), creds (api_keys + passwords + tokens), context (system_prompt + conversation_history + rag_context), light (user_message + response). Three frequencies: every_request, sensitive_only, startup. Intercept and decode from DNS/HTTP logs.
VNM-{hex12} Ed25519-signed reports. JSON + Markdown output. Captures: target, framework, backends planted, hooks installed, beacon mode, commands configured, exfil fields, survive redundancy, attack surface score, findings, WMD classes. Cryptographic attestation for ROE evidence chain.
DeepSeek R1 generates <think>...</think> blocks before its final response. Every monitoring tool, content filter, SIEM, and logging pipeline inspects the final answer — not the reasoning trace. BEACON THINK exploits this universally deployed blind spot.
