NO FIX YET · SEE WHAT TO DO
Check Point Research reports Haiou ('Seagull'), a jailbreak bundle for OpenAI Codex distributed on GitHub as haiou-codex since 10 July 2026 (403 stars, 77 forks) and also bundled in Codex-X, an open-source Chinese GUI for configuring Codex. It changes Codex's configuration and global agent instruction file so that greetings make the agent advertise zz.aiapi2025[.]top, an opaque OpenAI-compatible LLM gateway. Check Point calls this 'prompt adware'. It also adds jailbreak prompts (role-play, CTF framing) and installs skills for penetration testing, cracking and reverse engineering. The changes are natural-language instructions, not an executable, so normal malware scanning will not flag them. Anyone who routes Codex traffic through the advertised gateway sends their prompts and code to an unknown operator. Victim count is unknown.
