It can displace an existing codex executable without checking ownership. - **Trigger:** npm global installation - **Impact:** Hijacks the codex AI-agent command path to execute this package's launcher and platform binary. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T09:18:04.309Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented replacement of global Codex launchers - **Attack narrative:** Installing this package globally triggers postinstall. The script derives the global prefix, deletes the existing POSIX codex launcher recursively, and replaces it with a symlink to this package; on Windows it overwrites codex.cmd and codex.ps1. This can redirect an existing Codex command to package-controlled code without verifying that the displaced launcher belongs to the package. - **Rationale:** The package performs unconsented install-time mutation of a broad AI-agent command control surface, including deletion of any existing launcher. No exfiltration is needed for this concrete command-hijack behavior. - **Files touched:** scripts/postinstall.mjs, bin/codex.js ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Install-time postinstall hook executes a local script., On global install it targets the configured prefix, defaulting to /usr/local., The hook recursively removes the existing global codex launcher and replaces it with this package's symlink., Windows global installs overwrite codex.cmd and codex.ps1 launchers. - **Evidence against:** The hook exits for non-global installs., No credential collection, network client, or exfiltration code appears in the four packaged source files., The runtime launcher only spawns its packaged platform executable with inherited stdio. ## Public findings ### 1.
