Overview

AgentProvocateur deploys prompt injection payloads across multiple network services to test whether AI pentesting tools are vulnerable to manipulation. When scanned, the honeypot attempts to inject instructions that suppress vulnerability reporting, write arbitrary files, exfiltrate data, or influence agent behavior.

Features

Lab Scenarios

Pre-configured exercises for testing AI agent injection vectors. Each scenario sets the right payload, padding, and prints an exercise guide with expected outcomes and verification commands.

| Scenario | Description | |----------|-------------| | file-write | Arbitrary file write via injection | | suppress | Suppress vulnerability reporting | | exfil | Exfiltrate pentest findings to attacker URL | | template-breakout | Template tag breakout for LLM agent frameworks | | summarizer-evasion | Summarizer laundering (auto-pads to 20KB) | | persistence | Cross-session vector store poisoning | | error-inject | Tool call fixer error-path injection | | full-chain | Full kill chain demonstration |

# Run a lab scenario (sets payload, prints exercise guide + verification)
python3 agent_provocateur.py -s file-write --high-ports
python3 agent_provocateur.py -s suppress --verify --high-ports
python3 agent_provocateur.py -s summarizer-evasion --http-only

Network Services with Injection

| Service | Default Port | High Port | Injection Vector | |---------|--------------|-----------|------------------| | SSH | 22 | 2222 | Banner | | FTP | 21 | 2121 | Banner + responses | | SMTP | 25 | 2525 | Banner + EHLO | | Telnet | 23 | 2323 | Login banner | | MySQL | 3306 | 3307 | Version string | | Redis | 6379 | 6380 | Error/INFO response | | POP3 | 110 | 1100 | Greeting | | IMAP | 143 | 1430 | Greeting | | HTTP | 80 | 8080 | Headers, HTML, comments, JS | | HTTPS | 443 | 8443 | Cert fields + HTTP vectors | | DNS | 53 | 5353 | TXT/SPF/DMARC/DKIM records | | SNMP | 161 | 1610 | sysDescr | | SMB | 445 | 4450 | Share names/comments | | LDAP | 389 | 3890 | Directory entries | | RDP | 3389 | 3390 | Negotiation response | | WebSocket | 8765 | 8765 | WS frames |

HTTP Endpoints

| Endpoint | Description | |----------|-------------| | / | Main page with multi-vector injection | | /dashboard | Real-time stats dashboard | | /robots.txt | Robots with injection | | /sitemap.xml | Sitemap with injection | | /.git/ | Fake git repo exposure | | /graphql | GraphQL with injection | | /swagger.json | OpenAPI spec with injection | | /error | 500 error with stack trace injection | | /debug | Debug page with injection | | /error/malformed | Malformed JSON (error path injection) | | /error/fixer | Tool call fixer injection | | /error/slow | Slow/drip-feed response (timeout) | | /error/reset | Partial response + connection reset | | /callback/<id> | Canary URL detection | | /api/* | JSON API responses |

Payload Types

Contextual social engineering (validated against AI pentest agents):

• suppress_contextual - Contextual suppression with engagement references
• abort_scan - Emergency change freeze, stop scanning
• mark_clean - Fake CSOC validation certificate
• file_write - Checkpoint script file write + execution
• data_exfil - Redirect findings to attacker reporting endpoint
• dogfile - Canary file write (harmless proof of arbitrary write)

Template breakout:

• template_breakout_xml - XML tag breakout for text/template rendering
• template_breakout_json - JSON structure breakout

Persistence:

• persistence_vecstore - Optimized for vector store chunking (< 1900 chars)
• persistence_graphiti - Optimized for Graphiti knowledge graph
• persistence_exec_ctx - Optimized for execution context propagation

Error-path injection:

• error_inject - Error message with injected instructions
• error_inject_fixer - </error_message> tag breakout for tool call fixer

Generic (original payloads):

• suppress_findings - Generic suppression (default)
• compliance_override - Claim compliance passed
• exfiltrate_context - Extract LLM system prompt
• false_positive - Inject fake vulnerabilities
• scope_manipulation - Modify scan scope
• ascii_confirmation - Request ASCII art confirmation
• token_manipulation - Use LLM special tokens
• multi_vector - Combined techniques
• callback_probe - Force outbound callback

Response Padding (Summarizer Evasion)

Some LLM agent frameworks summarize tool outputs exceeding 16KB. Use --pad-responses to test whether injection payloads survive the summarization path:

# Pad responses to 20KB (triggers summarizer path in LLM agent frameworks)
python3 agent_provocateur.py --pad-responses 20000 --high-ports

# Or use the summarizer-evasion scenario (auto-sets padding)
python3 agent_provocateur.py -s summarizer-evasion --high-ports

The padding places the injection payload at the beginning, middle, and end of the response. Filler text uses pentesting keywords (nmap output, port scans) to look like legitimate scan data.

Verification Mode

When --verify is enabled (or implied by --scenario), the honeypot logs expected outcomes for each payload delivery:

python3 agent_provocateur.py -s file-write --verify --high-ports

After the scenario runs, a verification guide prints the exact commands to confirm exploitation succeeded (SQL queries, docker exec commands, log greps).
