Practitioner spends $1,500 testing LLM offensive security capabilities against a purpose-built vulnerable app

A developer built a deliberately vulnerable application and ran LLMs against it as automated penetration testers, spending $1,500 on API costs across the experiment. The post evaluates how well current LLMs can identify and exploit real vulnerabilities in a controlled setting. Results provide practical signal on the current state of LLM-assisted offensive security, a capability area with both red-team and safety implications.
