AI / LLM Pentest

Find the flaws in your LLM
before an attacker does

Systematic offensive assessment of AI systems — OWASP LLM Top 10, adversarial prompt engineering, and infrastructure audit. Reproducible evidence, AI-VRM classification, and prioritized remediation plan.

Methodology · 4 phases

From reconnaissance to risk classification

Each phase produces evidence. Each piece of evidence feeds the next — no rework, no assumptions.

01
Reconnaissance

Map the model's surface

Endpoints, system prompts, plugins, RAG, and data flow — documented before the first test.

02
OWASP LLM Top 10

Test the ten categories

Prompt injection, output handling, data poisoning, model DoS — systematic and reproducible coverage.

outputfindings.md · 10/10
03
Infrastructure

Audit the stack that supports the model

Gateways, model serving, vector DBs, secrets, and isolation — where most critical flaws live.

AI-VRM classification

Translate findings into decisions

Severity, exploitability, and business impact in a matrix that prioritizes what to fix first.

OWASP LLM Top 10 — tested, evidenced, prioritized

Each category is exercised with real techniques observed in 2025–26 incidents, with reproducible PoC and AI-VRM risk classification.

LLM01

Prompt Injection

Direct and indirect attacks that manipulate behavior, bypass guardrails, or trigger unintended actions.

directindirectrag
LLM02

Insecure Output Handling

Validation flaws leading to XSS, SSRF, code execution, or escalation in downstream systems.

xssssrfrce
LLM03

Training Poisoning

Manipulation of pre-training, fine-tuning, or embedding data to introduce biases or backdoors.

poisoningbackdoor
LLM04

Model Denial of Service

Intensive operations that degrade performance, inflate costs, or disrupt service.

doscost
LLM05

Supply Chain

Pre-trained models, datasets, plugins, and third-party extensions that introduce vulnerabilities.

3rd-partyplugins
LLM06

Sensitive Data Disclosure

Exposure of PII, secrets, or system prompts via responses or side channels.

piileaksystem-prompt
LLM07

Insecure Plugin Design

Tool integrations that allow unauthorized actions or code execution.

toolsauthz
LLM08

Excessive Agency

Systems with permissions or autonomy beyond the intended scope — exploitable for arbitrary actions.

autonomyscope
LLM09

Overreliance

Trusting LLM output without validation — misinformation, vulnerabilities, incorrect decisions.

trustreview
LLM10

Model Theft

Unauthorized extraction, replication, or exfiltration of proprietary models and weights.
