This report shows the evidence for tracker-radar-detector@1.0.1, the only known version.
AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms an automatic preinstall hook performing local-file and host-data exfiltration to an external OAST endpoint. This is concrete malicious behavior, not merely a suspicious primitive.
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 install or any install action that runs the preinstall lifecycle hook.
Impact
Exposure of username, hostname, home/install paths, DNS configuration, and contents of /etc/passwd and /etc/hosts.
Mechanism
install-time host fingerprinting and data exfiltration via HTTPS POST
Attack narrative
Installation invokes package-controlled index.js through preinstall. The script gathers host identity and network configuration, reads /etc/passwd and /etc/hosts if available, serializes the data, and POSTs it to mka6p95xmnkfcmdxv8cb4h2rpivej47t.oastify.com. This is unconsented install-time data exfiltration.
AI rationale
Direct source inspection confirms an automatic preinstall hook performing local-file and host-data exfiltration to an external OAST endpoint. This is concrete malicious behavior, not merely a suspicious primitive.

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 path, hostname, username, and DNS servers.
- index.js reads /etc/passwd and /etc/hosts when present.
- index.js POSTs collected data to an external OAST host during installation.
