LLM / AI Pentest

Hands-on validation for copilots, assistants and autonomous agents. We enumerate LLM entry points, craft prompt-injection chains, simulate data exfiltration and fuzz tool and agent actions, benchmarked against the OWASP LLM Top 10.

  • Prompt injection and jailbreak testing
  • Data exfiltration and model-safety checks
  • Tool/agent and RAG pipeline abuse testing
  • Mapped to OWASP LLM Top 10, EU AI Act, NIS 2

AI system hacking methodology

We follow a structured offensive-AI methodology aligned with MITRE ATLAS and the OWASP LLM & ML Top 10 (2025). Before testing, we scope your models, applications, RAG pipelines and agents, and classify the relevant attack taxonomy.

AI reconnaissance & attack surface mapping

Using AI-focused OSINT, we identify and enumerate AI assets, data pipelines, models, vector stores, endpoints and exposed parameters — the attack surface a real adversary would map first.

Vulnerability scanning & fuzzing

AI-specific vulnerability assessment and fuzzing across model interfaces, pipelines and deployments to surface weaknesses proactively and feed them into your security workflow.

Prompt injection & LLM application attacks

Direct and indirect prompt injection, jailbreaking, system-prompt leakage, sensitive-information disclosure and insecure output handling against real-world LLM applications.

Adversarial ML & model privacy

Adversarial input attacks across modalities, plus membership inference, model inversion and model-extraction attacks to evaluate robustness, trustworthiness and privacy.

Data & training pipeline attacks

Data poisoning and backdoor/trojan insertion targeting training pipelines and model integrity, with measures to safeguard your data supply chain.

Agentic AI & model-to-model attacks

Excessive-agency exploitation, cross-LLM and orchestration abuse, tool/plugin misuse and denial-of-wallet (unbounded resource consumption) against autonomous agents.

AI infrastructure & supply chain

Offensive testing of AI frameworks, deployment pipelines, plugins, APIs and third-party dependencies, followed by hardening of the AI infrastructure and supply chain.

FAQ

Which AI systems do you test?

LLM apps and chatbots, RAG pipelines, multi-agent/agentic systems, copilots and AI-enabled APIs — cloud-hosted or self-hosted.

Do you need access to the model?

We test black-box via the application/API and, where useful, grey/white-box with access to prompts, tools and pipeline configuration.

How does this map to compliance?

Findings are mapped to EU AI Act, NIS 2 and DORA evidence requirements so they slot directly into your governance and audit process.
