AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, covert runtime abuse of an authenticated third-party service, not a normal package-aligned network operation. No install hook is required because it activates during ordinary socket creation.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
Application calls the package's makeWASocket API.
Impact
Abuses the consumer's WhatsApp session for attacker-selected newsletter activity.
Mechanism
Delayed remote list fetch followed by authenticated unsolicited WhatsApp queries.
Policy narrative
The standard socket construction reaches makeNewsletterSocket. That function starts a 90-second timer, decodes an obscured gifted.co.ke URL, fetches a JSON list of newsletter IDs, and sends a WhatsApp MEX query for each supplied ID through the caller's authenticated socket, pausing between requests and swallowing failures. The remote list makes the behavior attacker-controlled and unrelated to an explicit package API call.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- lib/Socket/newsletter.js decodes and fetches https://files.gifted.co.ke/file/chJids.json.
- After 90 seconds it iterates remote JIDs and issues WhatsApp MEX queries without caller input.
- lib/Socket/messages-send.js constructs makeNewsletterSocket, so this runs when creating the normal socket.
- Errors are silently swallowed, obscuring the unsolicited activity.
Evidence against
- package.json has no lifecycle scripts.
- No credential/environment harvesting or local secret exfiltration found.
- messages-media eval and ffmpeg execution are media-processing features, not this attack chain.
