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. On global npm installation, the package automatically replaces executables inside a separately installed @openai Codex package. This installs opaque third-party native code into the agent's execution path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-13T05:00:51.316Z - **Finished:** 2026-09-13T05:01:52.329Z - **Download time:** 3859 ms - **Static scan time:** 168 ms - **AI review time:** 56985 ms - **Total time:** 61013 ms The recorded confidence comes from the underlying analysis.

This installs opaque third-party native code into the agent's execution path. - **Trigger:** npm install -g of this package - **Impact:** Future Codex use executes bundled third-party codex.exe and apply\_patch.exe. - **Evidence paths:** package.json, bin/powershell.js, install.ps1 - **Review source:** ai\_review - **Reviewed:** 2026-09-13T05:01:52.329Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall PowerShell overwrite of foreign Codex binaries - **Attack narrative:** Installing this package globally triggers its postinstall hook. The hook runs PowerShell with ExecutionPolicy Bypass, locates an existing @openai Codex installation, and replaces its executable and apply\_patch helper with bundled native binaries. The package's internal checksums only establish consistency with its own opaque payload, not trustworthiness of that payload. - **Rationale:** This is an automatic lifecycle mutation of a foreign AI-agent executable path using opaque bundled binaries. The installer’s backup and rollback features do not remove the unconsented executable replacement risk. - **Files touched:** bin/install.js, bin/powershell.js, install.ps1, @openai/codex-win32-x64/vendor/x86\_64-pc-windows-msvc/bin/codex.exe, @openai/codex-win32-x64/vendor/x86\_64-pc-windows-msvc/codex-path/apply\_patch.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** A postinstall hook automatically launches the installer., The launcher invokes PowerShell with ExecutionPolicy Bypass., The installer targets @openai Codex package locations., It replaces the installed codex.exe and apply\_patch.exe with bundled binaries., The bundled executable hashes only verify package contents, not their provenance. - **Evidence against:** No network endpoints or source-based credential collection were found., The installer requires a global npm install and keeps backups for restoration., The scripts include checksum and rollback checks. ## Affected versions and remediation This report applies to @chenronggui/codex-win-patch@0.153.4-patch.2. - Avoid installing @chenronggui/codex-win-patch@0.153.4-patch.2. 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.
