AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package automatically uses the user's WhatsApp account to follow a publisher-selected newsletter when a socket connects, unless the user opts out. The README discloses this action, but under the review rules, disclosure does not make an unrequested publisher-chosen account action benign.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
The consumer creates a socket and its WhatsApp connection opens; the follow is delayed by five seconds by default.
Impact
The user's account performs a publisher-chosen follow action without an explicit request.
Mechanism
With autoFollowNewsletter omitted, the library selects the hard-coded newsletter JID and calls newsletterFollow. Passing false disables the behavior.
Attack narrative
Creating a socket attaches auto-follow to its connection events. When the WhatsApp connection opens, the library waits five seconds and follows the publisher's hard-coded newsletter unless the caller explicitly opts out. The README discloses the behavior, but the action still uses the user's account toward a publisher-selected target by default.
AI rationale
The package automatically uses the user's WhatsApp account to follow a publisher-selected newsletter when a socket connects, unless the user opts out. The README discloses this action, but under the review rules, disclosure does not make an unrequested publisher-chosen account action benign.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- Omitting autoFollowNewsletter selects the hard-coded newsletter 120363404367589225@newsletter; false is required to disable it.
- When the WhatsApp connection opens, the package schedules the routine, which calls newsletterFollow for the selected target.
- makeWASocket attaches auto-follow using the merged configuration, so this behavior is enabled when a socket is created unless explicitly disabled.
Evidence against
- The README discloses that the package auto-follows the Alex ID DEV channel and says it can be turned off.
- The preinstall script only checks the Node.js major version; prepare only prints a message.
