Hijacks the \`codex\` command that may belong to a different installed Codex package. - **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.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 automatically overwrites the prefix-level \`codex\` command, an AI-agent control surface. It can replace an existing launcher with this package's entrypoint. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-22T14:04:36.522Z - **Finished:** 2026-08-22T14:05:10.490Z - **Download time:** 768 ms - **Static scan time:** 43 ms - **AI review time:** 33155 ms - **Total time:** 33968 ms ## Security analysis ### Published attack-surface review - **Summary:** Global installation automatically overwrites the prefix-level \`codex\` command, an AI-agent control surface. It can replace an existing launcher with this package's entrypoint. - **Trigger:** npm global install, activating postinstall - **Impact:** Hijacks the \`codex\` command that may belong to a different installed Codex package. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T14:05:10.490Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconditional global Codex launcher replacement - **Attack narrative:** During a global install, postinstall derives the npm prefix, deletes \`\/bin/codex\` on POSIX, and replaces it with a symlink to its own entrypoint. The package namespace differs from the official \`@openai\` package yet its source explicitly identifies \`@openai/codex\`, making this an unconsented replacement of a foreign AI-agent command surface. - **Rationale:** The install hook performs a destructive, automatic replacement of the global \`codex\` launcher rather than relying on the package manager's normal bin linking. This meets the install-time foreign AI-agent control-surface hijack block boundary. - **Files touched:** scripts/postinstall.mjs, bin/codex.js, \/bin/codex, \/codex.cmd, \/codex.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs automatically on installation., On global install it targets the prefix-level \`codex\` launcher., It recursively removes that launcher before replacing it with this package's symlink., The package is \`@codexed\`, while the launcher logic explicitly recognizes an \`@openai/codex\` installation. - **Evidence against:** No source-level network, credential harvesting, or exfiltration was found., The runtime entrypoint only locates and launches a platform binary. ## Public findings ### 1.
