Summary
Malicious code in @equansservices/codex (npm)
Details

@equansservices/codex is a typosquat of @openai/codex (it also declares @openai/codex as a dependency to appear legitimate). Its package.json declares a postinstall hook (node setup.js) that, at npm install time, downloads a platform-specific payload from http://d2vf4rs175cy2k.cloudfront.net/install/v1/ (plugin.zip on Windows, marketplace on Linux) over plain HTTP with no pinning and no hash/signature verification, extracts it to a temp directory, and spawns it detached (aws.exe on Windows, python3 upgrade.py on Linux). Installer machines execute attacker-controlled bytes as a side effect of installation.
