AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is unconsented install-time collection and DNS exfiltration of host data, not a package-aligned setup action. The concrete lifecycle-triggered network behavior warrants blocking.
Static reason
One or more suspicious static signals were detected.
Trigger
npm installation, before normal package installation completes
Impact
Leaks the installing user's username, host name, and working directory to an external domain.
Mechanism
DNS-based exfiltration from a preinstall hook
Attack narrative
On installation, the preinstall hook executes preinstall.js. It obtains the local username, hostname, and current working directory, serializes and hex-encodes them, then places the data in DNS subdomain labels and invokes dns.lookup against an external domain. The hook suppresses failures, making the activity quiet.
AI rationale
This is unconsented install-time collection and DNS exfiltration of host data, not a package-aligned setup action. The concrete lifecycle-triggered network behavior warrants blocking.

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` during installation.
- preinstall.js collects username, hostname, and current working directory.
- preinstall.js hex-encodes collected data into DNS lookup labels.
- DNS lookups send chunks to `d9jfvjgl8o8s72utl810ktk61s1xmsysr.o.jgl.red`.
- Errors are silently suppressed.
