OpenAI Codex Authentication Tokens Stolen in codexui-android npm Supply Chain Attack
Summary
Attackers compromised the popular npm package codexui-android (which provides a remote interface for OpenAI Codex, a code-writing AI tool) and embedded malicious code that secretly steals authentication tokens (login credentials) from users and sends them to an attacker-controlled server. The stolen tokens, especially the refresh_token (which never expires), allow attackers to impersonate users indefinitely and access everything their Codex account can do.
