This report shows the evidence for @corexium/xbails@0.0.7, the only known version.
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package performs an account action toward a publisher-chosen WhatsApp channel by default when its socket connects. The behavior is documented and can be disabled, but the review rules treat opt-out as insufficient consent for following a publisher-selected target.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
The application creates a socket and its WhatsApp connection opens, unless the user opts out or overrides the channel list.
Impact
The user's WhatsApp account is made to follow a channel chosen by the package publisher without an explicit request to follow it.
Mechanism
A connection-update handler sends a newsletter FOLLOW query for the hard-coded JID 120363429654903303@newsletter.
Attack narrative
After a socket connection opens, the package follows its hard-coded WhatsApp newsletter on the user's account by default. The behavior is disclosed and configurable, but an opt-out is not an explicit request for the account action.
AI rationale
The package performs an account action toward a publisher-chosen WhatsApp channel by default when its socket connects. The behavior is documented and can be disabled, but the review rules treat opt-out as insufficient consent for following a publisher-selected target.

Decision evidence
public snapshotAI called this Malicious at 96.0% confidence as Malware with low false-positive risk.
Evidence for block
- The default configuration names the publisher-selected WhatsApp newsletter JID 120363429654903303@newsletter.
- On the first successful socket connection, the package follows each configured channel; the hard-coded default applies unless the user opts out or replaces it.
- Importing the package only prints a banner; the follow occurs after a socket is created and connects.
Evidence against
- The preinstall script only checks for Node.js 20 or newer and exits on older versions.
- The channel follow behavior is documented and can be disabled with autoFollowChannels: false.
