Subsequent codex invocations are redirected to this package and its selected platform executable. - **Trigger:** Installing this package globally through npm triggers postinstall. - **Impact:** It can hijack the system-wide codex command and redirect an AI-agent CLI to package-controlled code. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T00:16:52.720Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall global CLI launcher replacement. - **Attack narrative:** The package runs postinstall automatically. For global installs it selects an environment-controlled prefix, deletes the existing POSIX codex launcher, and replaces it with a symlink to its own wrapper; on Windows it writes replacement command launchers. The wrapper then starts a platform-specific executable selected from this package's dependencies. This redirects future use of the globally named Codex agent without an explicit migration command. - **Rationale:** This is an automatic install-time takeover of a global AI-agent command outside the package directory. The global-install guard and absence of visible JavaScript exfiltration do not remove the concrete command-hijacking behavior. - **Files touched:** bin/codex.js, scripts/postinstall.mjs, $PREFIX/bin/codex, $PREFIX/codex.cmd, $PREFIX/codex.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Installation automatically runs a postinstall script., On global installation, the script uses the configured prefix or defaults to /usr/local., The script removes the existing global codex launcher and replaces it with a link to this package., Windows launchers are overwritten to run this package's JavaScript entry point., The scoped package presents itself in its README as OpenAI's Codex CLI. - **Evidence against:** The postinstall script exits for non-global installs., The inspected JavaScript contains no network request or credential-exfiltration code., The CLI wrapper launches a local platform executable with inherited standard I/O. ## Public findings ### 1.
