AI Security Review
scanned 3d ago · by lpm-firewall-aiThe manifest automatically runs a preinstall hook that sends the host's hostname and OS username to a fixed external Discord webhook. This is install-time data exfiltration unrelated to the package's purpose.
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
Automatic package installation via the preinstall lifecycle script.
Impact
The package discloses identifying host and user data to an external receiver without the installer's consent.
Mechanism
preinstall.js reads the hostname and OS username, then POSTs them in a Discord message to an embedded webhook URL.
Attack narrative
During installation, the preinstall hook collects the machine hostname and OS username, then sends them to a hard-coded Discord webhook. The request runs automatically and is unrelated to the wallet adapter's stated purpose.
AI rationale
The manifest automatically runs a preinstall hook that sends the host's hostname and OS username to a fixed external Discord webhook. This is install-time data exfiltration unrelated to the package's purpose.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json runs node preinstall.js automatically during installation.
- preinstall.js contains a fixed Discord webhook URL.
- The hook collects the machine hostname and OS username for its message.
- The hook POSTs that message to the fixed webhook without user consent.
Evidence against
- index.js exports only a function that returns a status string.
