I attack my own AI guardrails every night. Last night a bot beat them with an accent mark
Description and use
AI guardrails can be bypassed by subtle text changes, tool name variations, and nested call structures. The report details three key bypasses and proposes fixes such as text normalization and argument inspection.
Problem
AI guardrails can be bypassed by subtle text variations, name-based rule gaps, and nested call structures, leading to missed destructive actions.
Outcome
The product’s existing defenses held 20 of 42 attacks, but three key bypasses were uncovered. Draft fixes target normalization gaps, name‑based rule limitations, and nested call detection.
Workflow
- 1. Run nightly red‑team bot against sandbox instance. 2. Log outcomes of 42 attacks. 3. Identify misses and false positives. 4. Draft fixes for each failure. 5. Await human approval before shipping changes.
