Can silently hijack the codex command to execute this package's platform binary. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.149.0-codexed.5 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Global npm installation automatically overwrites the prefix-level codex launcher and routes it to this package's executable. This targets a broadly used AI-agent command name while presenting documentation for the unrelated @openai package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-23T00:41:01.048Z - **Finished:** 2026-08-23T00:41:39.787Z - **Download time:** 754 ms - **Static scan time:** 34 ms - **AI review time:** 37950 ms - **Total time:** 38739 ms ## Security analysis ### Published attack-surface review - **Summary:** Global npm installation automatically overwrites the prefix-level codex launcher and routes it to this package's executable. This targets a broadly used AI-agent command name while presenting documentation for the unrelated @openai package. - **Trigger:** npm global installation invokes postinstall. - **Impact:** Can silently hijack the codex command to execute this package's platform binary. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/codex.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-23T00:41:39.787Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall replacement of global codex launchers - **Attack narrative:** Installing this differently scoped package globally invokes postinstall. The script resolves the global npm prefix, deletes its existing codex launcher, and replaces it with a symlink or Windows wrappers pointing to the package. The README instead instructs installation of @openai/codex, supporting impersonation of that AI-agent command. Subsequent codex invocations execute the package-selected platform binary. - **Rationale:** The automatic global replacement of an existing AI-agent command by an @codexed package is a concrete unconsented control-surface hijack. No exfiltration was found, but it is not required for the install-time command takeover. - **Files touched:** scripts/postinstall.mjs, bin/codex.js, \/bin/codex, \/codex.cmd, \/codex.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs postinstall automatically., On global install, postinstall selects the npm prefix., It forcibly removes and replaces prefix/bin/codex with its own launcher., The README directs users to install @openai/codex, not this @codexed package., The replacement launcher dispatches to a platform binary. - **Evidence against:** No source evidence of credential harvesting, network requests, or data exfiltration., The postinstall mutation is limited to global codex launchers rather than arbitrary project files. ## Public findings ### 1.
