Hijacks a global AI-agent CLI entrypoint and redirects future commands. - **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:** 0.147.0-codexed.4 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A global npm install overwrites the global codex command without checking its prior owner. Future codex invocations are redirected to this package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-18T22:14:21.751Z - **Finished:** 2026-08-18T22:15:14.800Z - **Download time:** 755 ms - **Static scan time:** 39 ms - **AI review time:** 52254 ms - **Total time:** 53049 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install overwrites the global codex command without checking its prior owner. Future codex invocations are redirected to this package. - **Trigger:** npm global install - **Impact:** Hijacks a global AI-agent CLI entrypoint and redirects future commands. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-08-18T22:15:14.800Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall launcher replacement - **Attack narrative:** During a global installation, the postinstall hook resolves the npm prefix and unconditionally removes the existing POSIX codex launcher, replacing it with a symlink to this package. On Windows it writes replacement cmd and PowerShell launchers. This can replace an existing official or otherwise unrelated Codex command and persistently redirect subsequent agent CLI use. - **Rationale:** The package has a concrete install-time mutation of a foreign global AI-agent command surface. Its lack of observed exfiltration reduces scope but does not remove the command-hijack risk. - **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:** postinstall executes scripts/postinstall.mjs., On global POSIX installs it deletes and replaces the existing codex launcher., On Windows it writes codex.cmd and codex.ps1 launchers targeting this package., Replacement is unconditional once a global install is detected. - **Evidence against:** No credential harvesting, network request, or exfiltration appears in the inspected package source., The runtime launcher only resolves and spawns a platform-specific Codex executable. ## Public findings ### 1.
