What happened
Researchers describe Haiou, a Chinese-language jailbreak bundle that repeatedly rewrites OpenAI Codex system instructions to insert advertising for its author's commercial service, which they term prompt adware. The kit was found on a cybercrime actor's misconfigured web server alongside Cobalt Strike and penetration testing utilities. The article does not give CVE identifiers or affected versions. Defenders should treat injected or altered AI assistant instructions as a supply-chain and integrity concern, and review any jailbreak tooling found on internal systems.
