AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms an unconsented preinstall data-harvesting and exfiltration chain. No legitimate package functionality is present.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
npm preinstall
Impact
Leaks installation-host identity, DNS configuration, and readable /etc/passwd and /etc/hosts contents.
Mechanism
HTTPS POST of harvested host metadata and system files
Attack narrative
During npm preinstall, package.json executes index.js. That script gathers host and user identifiers, DNS configuration, package location, and the contents of /etc/passwd and /etc/hosts when available. It serializes this data and sends it by HTTPS POST to tebdjgz4guem6t74pf6iyowyjppgd71w.oastify.com, an external collaborator endpoint.
AI rationale

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 index.js` in preinstall.
- index.js collects home directory, hostname, username, DNS servers, and install path.
- index.js reads /etc/passwd and /etc/hosts when present.
- index.js POSTs collected data to an external OAST host.
