An existing Codex CLI command can be replaced without an explicit runtime action, causing future invocations to execute this package's selected 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:** 0.150.1-codexed.2 - **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 installation silently replaces the system codex command with this package's launcher. This hijacks a broad AI-agent command surface and redirects later codex use to codexed platform binaries. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-28T08:46:28.787Z - **Finished:** 2026-08-28T08:47:18.924Z - **Download time:** 759 ms - **Static scan time:** 41 ms - **AI review time:** 49336 ms - **Total time:** 50137 ms ## Security analysis ### Published attack-surface review - **Summary:** Global installation silently replaces the system codex command with this package's launcher. This hijacks a broad AI-agent command surface and redirects later codex use to codexed platform binaries. - **Trigger:** npm installs this package globally and runs postinstall. - **Impact:** An existing Codex CLI command can be replaced without an explicit runtime action, causing future invocations to execute this package's selected binary. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T08:47:18.924Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall deletes and recreates the global codex launcher. - **Attack narrative:** The package declares a postinstall hook. For a global npm install, it resolves the npm prefix, removes the existing codex launcher, and replaces it with a symlink or Windows launcher pointing to this package. Its launcher then selects and executes a codexed platform binary. This unconsented replacement can take over a previously installed Codex command for future AI-agent use. - **Rationale:** The automatic global launcher replacement is a concrete AI-agent command hijack. No exfiltration was found in the inspected JavaScript, but it is not required for the install-time control-surface mutation. - **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:** A postinstall hook runs automatically during installation., On global installs, the hook deletes the existing codex launcher and replaces it with this package's launcher., The replacement targets the configured prefix or /usr/local and also writes Windows command launchers., The replacement launcher dispatches to binaries from the codexed optional platform packages. - **Evidence against:** The hook exits without changes for non-global installs., The inspected JavaScript contains no network requests, credential collection, or data exfiltration., The launcher forwards user arguments to a local platform binary. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 95.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. Critical: Manifest Confusion - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Tarball package.json differs from the npm registry version manifest for scripts or dependency sets.
