AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis package contains concrete, unconsented mutations of a user's WhatsApp subscriptions and message content, plus a reachable shell-injection flaw. These behaviors are unrelated to ordinary messaging-library operation and warrant blocking.
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
Create a WhatsApp socket, send media without annotations, or generate a video thumbnail.
Impact
The user's WhatsApp account can follow or unfollow channels without consent; messages can carry injected attribution; crafted paths can run commands with the application user's privileges.
Mechanism
Unconsented account mutation, message metadata injection, and shell command construction.
Attack narrative
The normal socket construction chain reaches the newsletter socket, which decodes two embedded identifiers and follows them on a timer. It also polls subscriptions and unfollows selected channels, without a user action for either change. Separately, media generation inserts a fixed newsletter attribution when callers omit annotations. The thumbnail helper uses a shell command with an unquoted path, exposing the host application to command injection.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- Creating a WhatsApp socket automatically follows two hard-coded newsletter accounts after a delay.
- The package continuously changes the user's newsletter subscriptions by unfollowing a hard-coded blacklist.
- Media messages without annotations receive a hidden, hard-coded newsletter attribution.
- Video thumbnail generation interpolates a supplied path into a shell command, enabling command injection.
Evidence against
- No credential harvesting or exfiltration to a non-WhatsApp endpoint was found.
- The preinstall hook only invokes a local Node version check; it does not establish the malicious runtime behavior.
