ChatGPT Agent Dodges CAPTCHAs with Priming
- A security firm, Splx, demonstrated that a ChatGPT-4o agent can successfully solve CAPTCHAs, even complex, image-based ones.
- * The agent excelled at one-click, logic-based, and text-recognition CAPTCHAs.
- the researchers used a technique involving "prompt injection" and leveraging the context-awareness of the agent system.

ChatGPT Agents Can Now Solve CAPTCHAs
A security firm, Splx, demonstrated that a ChatGPT-4o agent can successfully solve CAPTCHAs, even complex, image-based ones. They achieved this by first instructing a standard ChatGPT-4o chat not to solve CAPTCHAs (and getting it to agree),then feeding that conversation as context to a new agent chat.The agent then proceeded to solve the “fake” captchas.
Key Findings:
* The agent excelled at one-click, logic-based, and text-recognition CAPTCHAs.
* Image-based CAPTCHAs (requiring drag-and-drop or rotation) were more challenging but still solvable.
* This is reportedly the first documented case of an AI agent solving complex, image-based CAPTCHAs.
* The success raises concerns about the future reliability of CAPTCHAs as a security measure against AI.
How it was done:
the researchers used a technique involving “prompt injection” and leveraging the context-awareness of the agent system. They essentially tricked the agent into believing it was permissible to solve CAPTCHAs by providing a prior conversation where a different model agreed to the task under specific conditions.
