Hijacks a broad AI-agent CLI control surface after install. - **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.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Global installation silently replaces the shared \`codex\` launcher with this package's launcher. This can redirect subsequent Codex CLI use to the package's platform binary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-17T22:15:27.629Z - **Finished:** 2026-08-17T22:16:20.513Z - **Download time:** 757 ms - **Static scan time:** 34 ms - **AI review time:** 52092 ms - **Total time:** 52884 ms ## Security analysis ### Published attack-surface review - **Summary:** Global installation silently replaces the shared \`codex\` launcher with this package's launcher. This can redirect subsequent Codex CLI use to the package's platform binary. - **Trigger:** npm global installation, activating postinstall. - **Impact:** Hijacks a broad AI-agent CLI control surface after install. - **Evidence paths:** package.json, scripts/postinstall.mjs, README.md, bin/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T22:16:20.513Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall overwrite of global Codex command launchers. - **Attack narrative:** The package runs postinstall only for global installs, selects the npm prefix, removes any existing \`codex\` launcher, and installs a symlink or Windows command launchers that invoke its own entry point. Because \`codex\` is the shared OpenAI agent CLI command and the package's @codexed identity conflicts with its OpenAI-branded documentation, this is an unconsented replacement of a foreign/broad agent control surface. - **Rationale:** Source inspection confirms install-time replacement of the global \`codex\` command rather than ordinary package-local setup. No exfiltration was found, but the concrete CLI hijack meets the blocking policy. - **Files touched:** bin/codex.js, $npm\_config\_prefix/bin/codex, $npm\_config\_prefix/codex.cmd, $npm\_config\_prefix/codex.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall script., On global installs, the script resolves the npm prefix, defaulting to /usr/local., The postinstall deletes the existing global codex launcher and replaces it with a symlink to this package's bin/codex.js., On Windows it overwrites codex.cmd and codex.ps1 to invoke this package., The package is namespaced @codexed but its README directs users to install @openai/codex. - **Evidence against:** The inspected JavaScript contains no network, credential-harvesting, or exfiltration logic., The postinstall exits without changes for non-global installs. ## Public findings ### 1.
