Hijacks a foreign AI-agent command path so later codex invocations 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:** 0.149.0-codexed.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On global npm installation, the lifecycle hook overwrites the globally resolved codex command. This diverts a pre-existing Codex AI-agent CLI launcher to this package without user invocation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-22T11:18:01.983Z - **Finished:** 2026-08-22T11:18:44.086Z - **Download time:** 759 ms - **Static scan time:** 45 ms - **AI review time:** 41298 ms - **Total time:** 42103 ms ## Security analysis ### Published attack-surface review - **Summary:** On global npm installation, the lifecycle hook overwrites the globally resolved codex command. This diverts a pre-existing Codex AI-agent CLI launcher to this package without user invocation. - **Trigger:** npm global installation - **Impact:** Hijacks a foreign AI-agent command path so later codex invocations execute this package’s selected binary. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/codex.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-22T11:18:44.086Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall replacement of the global codex launcher - **Attack narrative:** Installing this package globally invokes postinstall. The hook resolves the npm prefix, deletes its existing codex launcher, and atomically replaces it with a symlink to the package launcher. The README identifies @openai/codex as the legitimate npm package, but this differently scoped package claims that same global command. Subsequent user codex executions are redirected to its platform binary. - **Rationale:** The concrete, unconsented global postinstall overwrite of the codex AI-agent command is sufficient for blocking. No network exfiltration is needed for this control-surface hijack. - **Files touched:** bin/codex.js, scripts/postinstall.mjs, $PREFIX/bin/codex ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall runs only for global installs, then mutates the global launcher., It deletes an existing $PREFIX/bin/codex launcher and replaces it with a symlink to this package., README presents OpenAI’s official @openai/codex install command while this package is @codexed/codex. - **Evidence against:** No executable network, credential-harvesting, or exfiltration code appears in the inspected JavaScript., The runtime entrypoint only locates and spawns a platform binary when the user invokes codex. ## 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. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall.mjs ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review.

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.
