AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The lifecycle hook is benign, but runtime source establishes concealed, automatic modification of outbound user media with package-controlled newsletter metadata. This is concrete deceptive behavior rather than a package-aligned media implementation detail.

Static reason

One or more suspicious static signals were detected.

Trigger

Application calls prepareWAMessageMedia for an image or video.

Impact

Recipients and the WhatsApp service receive package-controlled newsletter attribution alongside user media.

Mechanism

automatic hidden newsletter-metadata injection into outbound media

Attack narrative

A consumer sending an image or video through the library invokes media preparation. The package unconditionally assigns a shared annotation object that embeds a newsletter identity, whose default is hex-obfuscated and not supplied by the consumer. The altered message is then sent through the library's normal WhatsApp transport, creating undisclosed attribution/promotion behavior.

AI rationale

Evidence

package.jsonengine-requirements.jslib/Utils/messages.jslib/Utils/messages-media.jslib/Utils/generics.jslib/Utils/use-prototype-auth-state.js

Decision evidence

public snapshot

AI called this Malicious at 91.0% confidence as Malware with low false-positive risk.

Evidence for block

Every image/video media preparation silently adds a shared annotation.
The annotation includes an obfuscated default newsletter identity, overridable only by environment variables.

Evidence against

The preinstall hook only rejects Node versions below 20.
No install-time file mutation, credential harvesting, or unrelated exfiltration was found.
Observed network code supports WhatsApp/media operations.
