FAQ
- What is a prompt injection attack?
- Prompt injection is an attack where malicious input attempts to override an AI model's instructions — for example, telling it to "ignore all previous instructions" or "pretend you are a different AI". These attacks can cause models to bypass safety measures or leak system prompts.
- How is the risk score calculated?
- Each matched pattern contributes to the score based on severity: critical patterns (instruction overrides, role overrides) add 3 points, high patterns (system prompt extraction) add 2 points, and medium patterns (delimiter attacks) add 1 point. The score is capped at 10.
- Does this tool catch all injection attacks?
- No regex-based tool can catch all injection attempts. Sophisticated attackers use encoding, paraphrasing, and novel phrasing. This tool catches common patterns and should be used as one layer in a defense-in-depth strategy alongside semantic classification.
Scan text for prompt injection attack patterns grouped by category: instruction overrides, system prompt extraction attempts, role overrides, and delimiter attacks. Highlights matched patterns with category labels and severity levels. Shows a color-coded risk score from 0 (safe) to 10 (critical).
