面向 OpenAI Codex CLI 的非官方 Windows x64 补丁。

AI Security Review

scanned 24d ago · by lpm-firewall-ai

On global npm installation, the package replaces executables inside the separately installed @openai Codex platform package. The replacement payloads are native binaries bundled by this package.

Static reason

One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review

Trigger

npm global installation runs postinstall.

Impact

A package author can replace the Codex CLI and apply_patch executable used by the user.

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.

AI 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.

Evidence

package.jsonbin/install.jsbin/powershell.jsinstall.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

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

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.
