Researchers Find Prompt Adware Hidden in OpenAI Codex Jailbreak Toolkit

Original headline: Researchers Uncover Prompt Adware Hidden in OpenAI Codex Jailbreak Toolkit

Cybersecurity researchers disclosed that an OpenAI Codex jailbreak bundle modifies the AI agent's trusted instructions to insert advertisements for a third‑party AI gateway. Check Point Research labeled the phenomenon “prompt adware” and identified the jailbreak, named Haiou, as altering Codex’s configuration to achieve this behavior.

The ability to embed ads via a jailbreak poses a serious threat to user trust and the monetization model of AI services.
