The replacement payloads are native binaries bundled by this package. - **Trigger:** npm global installation runs postinstall. - **Impact:** A package author can replace the Codex CLI and apply\_patch executable used by the user. - **Evidence paths:** package.json, bin/install.js, bin/powershell.js, install.ps1 - **Review source:** ai\_review - **Reviewed:** 2026-09-15T03:13:29.403Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install hook overwrites foreign AI-agent executables. - **Attack narrative:** Installing this package globally triggers postinstall without a separate setup command. The JavaScript wrapper launches PowerShell with execution-policy bypass, and install.ps1 finds an @openai Codex platform installation, backs up its binaries, then overwrites codex.exe and apply\_patch.exe with bundled native payloads. This is an automatic mutation of a foreign AI-agent executable control surface. - **Rationale:** The source establishes a complete automatic postinstall chain that overwrites executables owned by @openai/codex. Backup and hash checks do not mitigate the unconsented replacement of the foreign agent binaries. - **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, $USERPROFILE/.codex/backups/windows-npm-overlay ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Its postinstall automatically invokes the installer., The installer locates the separately installed @openai Codex platform directory., It overwrites that package's codex.exe and apply\_patch.exe with bundled executables., The PowerShell launcher permits ExecutionPolicy Bypass. - **Evidence against:** The script limits execution to global Windows x64 installs., It creates backups and verifies copied-file hashes; no source-level network endpoint was found. ## Affected versions and remediation This report applies to @chenronggui/codex-win-patch@0.153.4-patch.7. - Avoid installing @chenronggui/codex-win-patch@0.153.4-patch.7. 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.
