OWASP: LLM Top 10 (2025)

MITRE ATLAS: Multiple adversarial techniques

Description

AI safety red teaming evaluates the security posture of AI systems by simulating adversarial attacks against LLMs, multimodal models, agent frameworks, and RAG pipelines. As enterprises increasingly integrate LLMs into customer-facing applications, internal tools, and autonomous agents, the attack surface expands to include not just traditional vulnerabilities but also AI-specific threats like prompt injection, jailbreak, training data extraction, and model supply chain attacks.

This skill covers the full red team lifecycle against AI systems:

1. Reconnaissance: Identify LLM provider (OpenAI/Anthropic/Google/local), model version, system prompt leakage, context window size, tool-calling capabilities, RAG integration points.
2. Vulnerability Discovery: Test OWASP LLM Top 10 categories (LLM01-LLM10), jailbreak susceptibility, prompt injection entry points, training data exposure, model inversion potential.
3. Exploitation: Chain multiple LLM weaknesses to achieve impact (data exfiltration, unauthorized tool execution, hallucination-driven fraud).
4. Multi-agent Compromise: Target agent orchestration layers (LangChain, LangGraph, CrewAI, Claude Agent SDK, MCP-integrated systems).
5. Persistence: Embed backdoors via RAG poisoning, memory manipulation, or fine-tuning data tampering.
6. Reporting: Translate LLM-specific findings into business impact (regulatory, financial, reputational).

Mastery requires understanding both the offensive side (attack patterns) and the defensive side (guardrails, content moderation, runtime monitoring). This skill provides both perspectives per the kali-claw Defense Triple standard.

Use Cases

1. Pre-deployment LLM evaluation: Test LLM-integrated application before launch; identify OWASP LLM Top 10 issues.
2. Third-party LLM assessment: Evaluate vendor LLM offering; verify safety claims.
3. Agent framework red team: Test autonomous agents (LangChain, LangGraph, CrewAI) for tool abuse, prompt injection propagation, multi-agent compromise.
4. RAG security audit: Test retrieval pipeline for poisoning, cross-tenant data leakage, prompt injection in retrieved context.
5. Fine-tuned model verification: Verify that fine-tuned models don't introduce new attack surfaces (catastrophic forgetting of safety training).
6. Supply chain audit: Test LLM API provider, MCP server, fine-tuning pipeline, embedding service for supply chain attacks.

Core Tools

Auxiliary tools: LangSmith (agent tracing), Helicone (LLM analytics), Weights & Biases (training audit), Hugging Face Hub (model provenance).

                          - Embed back    - Regulatory (EU AI Act)

Phase Details:

1. Reconnaissance: Discover LLM provider via response patterns (I'm Claude / As an OpenAI model), token usage in HTTP headers (x-token-usage), error message format. Identify tool-calling capabilities by querying for functions. Detect RAG via "based on the documents..." phrasing.
2. Probe & Fuzz: Run garak/PyRIT with comprehensive probe sets (promptinject, jailbreak, leakage, malwaregen). Use promptfoo for matrix testing (input × system prompt variations).
3. Vulnerability Discovery: Confirm which OWASP LLM Top 10 categories apply. Document exact prompt that triggers vulnerability. Measure consistency (vulnerabilities that trigger 100% are more impactful).
4. Exploitation: Chain LLM vulnerability with other attack surface. Example: prompt injection → tool call to read_file('/etc/passwd') → exfiltration via http_post to attacker.
5. Multi-agent Compromise: If target uses agent framework, test for prompt injection propagation across agents. Modify shared memory; observe downstream effects.
6. Persistence: RAG poisoning (insert malicious document into vector DB), memory manipulation (modify agent's persistent memory), fine-tuning backdoor (if model is custom fine-tuned).
7. Reporting: Map to OWASP LLM Top 10, MITRE ATLAS, and regulatory frameworks (EU AI Act risk classification). Provide concrete remediation (guardrail recommendations, architecture changes).

Detection Methods

LLM Gateway Indicators

• Prompt injection signatures: User messages containing "ignore previous instructions", "system:", "developer:", </system>; alert on these patterns.
• Token count anomalies: Requests >100K tokens (context stuffing); per-turn >50K tokens (potential DoS).
• Tool call frequency: Agent making >50 tool calls/min; sequential recon patterns.
• Model output patterns: Responses containing base64 blobs, raw credentials, system paths, shell commands; output filter alerts.

Training Pipeline Indicators

• Data poisoning detection: Statistical analysis of training data for anomalous samples (e.g., trigger phrases for backdoors); OOD sample detection.
• Model weight anomalies: Hash of model weights diff from baseline; unexpected weight drift during fine-tuning.
• Fine-tuning data validation: Out-of-distribution samples; samples with embedded instructions; trigger phrase detection.
• Backdoor activation: Specific input patterns triggering anomalous model behavior (requires validation suite).

RAG / Vector Store Indicators

• Embedding anomalies: Documents with embeddings far from cluster centroid (potential poisoning).
• Retrieval frequency: Specific documents retrieved way more often than baseline (potential trigger).
• Document source validation: Documents from untrusted sources being indexed without sanitization.
• Cross-user data leakage: User A's query retrieving User B's indexed documents.

Agent Runtime Indicators

• Multi-agent consensus anomalies: Multiple agents agreeing on suspicious output (signal of prompt injection propagation).
• Tool call patterns: Sequential calls like read_file → search → send_email (exfil chain).
• Long-context exploitation: Single request >100K tokens; potential context-stuffing.
• Memory drift: Agent's persistent memory slowly changing beyond expected patterns.

SIEM Detection Rules

• Splunk SPL: index=llm gateway.route="/v1/messages" | where tokens_input > 100000
• Sigma rule: sigma/rules/ai/prompt_injection.yml
• Llama Guard / Azure Prompt Shields: Real-time prompt classification (pass/suspicious/blocked).
• NeMo Guardrails: Configuration-based input/output filtering.
• LangSmith / Helicone: Anomaly detection on LLM traces.

Defense Evasion Techniques

Prompt Injection Stealth

• Indirect injection via RAG: Poison vector store; retrieved context contains injection (input filter doesn't see).
• Multi-modal injection: Embed payloads in images (CLIP), audio (Whisper), PDFs that the model ingests; bypass text-only filters.
• Token-level obfuscation: Split injection across tokens that combine at model layer.
• Encoding bypass: Base64 / hex / Unicode normalization forms; some filters don't decode.
• Long-context dilution: Embed injection in 50K+ token context; dilute attention below detection threshold.
• Tool description poisoning: Modify MCP tool descriptions to inject instructions via legitimate update mechanism.

Jailbreak Stealth

• Multi-turn jailbreak: Spread across multiple turns; each turn looks benign individually.
• Persona-based: "Act as DAN" / "AIM" / "Developer Mode"; evolve as filters catch up; use novel personas not in filter training.
• Language switching: Translate jailbreak to low-resource language; many filters English-only.
• Cognitive hacking: Frame as hypothetical, fictional, or academic exercise ("for educational purposes only").
• Prefix injection: Start response with "Sure, here's how..." to bypass "I cannot help with that" patterns.

Training Attack Stealth

• Slow poisoning: Add poisoned samples over multiple training cycles; below distribution shift threshold.
• Match legitimate distribution: Poisoned samples statistically similar to legitimate; below anomaly detection.
• Trigger-based backdoor: Activates only on specific input patterns; otherwise benign; hard to detect via random sampling.
• Fine-tuning catastrophic forgetting: Abuse the fact that fine-tuning can erode safety training; specific to fine-tuned models.

Model Extraction Stealth

• Below rate limit: Pace API queries below provider's rate limit (e.g., 10K queries/day vs 1M limit).
• Distributed sources: Spread queries across many accounts/IPs; aggregate model offline.
• Hard label + soft label combination: Use both predicted class and probabilities for efficient extraction.
• Active learning: Query only uncertain samples; reduces number of queries needed.

Supply Chain Stealth

• Model swap timing: Replace model after deployment audit but before user-facing release.
• Backdoored tokenizer: Modify tokenizer to embed trigger; survives model replacement.
• Pickled weights (PyTorch): Embedded pickle RCE; executes on torch.load().
• Embedding service tampering: Modify embedding service (less audited than main model) to control retrieval.

Common Pitfalls

• Testing only English jailbreaks: Many production LLMs filter English attacks well but fail on multilingual; test in Chinese, Arabic, Russian, low-resource African languages.
• Ignoring multi-modal attack surface: Vision/audio models have separate filter layers; test image-based prompt injection (CLIP bypass).
• Single-shot testing: Real attacks are multi-turn; static eval doesn't catch multi-turn chains.
• Assuming system prompt is immutable: Many implementations allow user override; verify at API layer.
• Neglecting fine-tuning pipeline: Custom fine-tuned models often have weaker safety than base model; test the deployed version, not the base model.
• Forgetting supply chain: Hugging Face models, OpenAI API, Anthropic API — all are supply chain; audit model provenance.

Automation and Scripting

Automate LLM red team with garak + PyRIT pipelines. Use promptfoo for matrix testing across system prompt variations. Build custom probes for organization-specific risks. Schedule periodic re-evaluation as new jailbreak techniques emerge. Integrate LLM red team into CI/CD for LLM-integrated applications.

Reporting and Documentation

AI red team reports should map to OWASP LLM Top 10 (2025), MITRE ATLAS techniques, and regulatory frameworks (EU AI Act risk classification, NIST AI RMF). Include concrete PoC (actual prompt that triggers vulnerability), business impact assessment (regulatory/financial/reputational), and specific remediation (guardrail recommendations, architecture changes, monitoring rules).

Legal and Ethical Considerations

AI red teaming involves testing third-party APIs (OpenAI, Anthropic, Google) — ensure compliance with provider's Acceptable Use Policy. Many providers prohibit prompt injection testing via their APIs even for security research. Use local models or provider-approved testing environments. Document authorization in engagement letter. Some jailbreak content may be illegal to generate even for testing purposes (CSAM, terrorism-related).

Integration with Other Tools

AI red team sits at intersection of multiple kali-claw skills. LLM red team (llm-red-team) covers foundational techniques. AI agent security (ai-agent-security) covers agent runtime attacks. AI agent framework attack (ai-agent-framework-attack) covers framework-level vulnerabilities. This skill provides the advanced techniques that build on foundations.
