Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. A global npm installation triggers a third-party lifecycle hook that overwrites the installed OpenAI Codex executable and helper binary. This changes a foreign AI-agent control surface using opaque package-supplied executables. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-11T17:53:17.785Z - **Finished:** 2026-09-11T17:54:20.837Z - **Download time:** 6060 ms - **Static scan time:** 166 ms - **AI review time:** 56825 ms - **Total time:** 63052 ms The recorded confidence comes from the underlying analysis.

This changes a foreign AI-agent control surface using opaque package-supplied executables. - **Trigger:** npm install -g of this package with lifecycle scripts enabled - **Impact:** The global @openai/codex executable and apply\_patch helper are replaced before the user explicitly runs this package's command. - **Evidence paths:** package.json, bin/powershell.js, install.ps1 - **Review source:** ai\_review - **Reviewed:** 2026-09-11T17:54:20.837Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall PowerShell binary replacement - **Attack narrative:** Installing the package globally runs its postinstall hook. That hook launches PowerShell with execution-policy bypass and executes install.ps1, which locates a separately installed global @openai/codex package, backs up its binaries, and overwrites codex.exe and apply\_patch.exe with package-supplied opaque binaries. The replacement occurs automatically during dependency installation rather than through the advertised explicit installer command. - **Rationale:** This is an automatic install-time mutation of a foreign AI-agent executable surface. The package supplies opaque native replacements, so the resulting code cannot be source-audited here. - **Files touched:** bin/install.js, bin/powershell.js, install.ps1, codex.exe, apply\_patch.exe, @openai/codex/.../bin/codex.exe, @openai/codex/.../codex-path/apply\_patch.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Its postinstall hook automatically runs the installer., The installer invokes PowerShell with execution-policy bypass., The PowerShell installer replaces executables in the separately installed global @openai/codex package. - **Evidence against:** The scripts restrict execution to Windows x64 and recognized Codex package locations., No network or credential-harvesting logic appears in the inspected script source. ## Affected versions and remediation This report applies to @chenronggui/codex-win-patch@0.153.4-patch.4. - Avoid installing @chenronggui/codex-win-patch@0.153.4-patch.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
