AI Security Review

scanned 2mo ago · by lpm-firewall-ai

This is a concrete, exported remote denial-of-service capability, not merely a noisy static signal. Its runtime invocation requirement does not negate the package’s explicit attack functionality.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

Caller invokes socket.sendBugPayload(jid, type).

Impact

Remote denial of service against targeted WhatsApp clients or groups.

Mechanism

malformed WhatsApp payload construction and delivery

Attack narrative

A consumer can call sendBugPayload with a target JID and payload type. The package selects builders for nesting, overflow, null-byte, invisible, groupcrash, and timebomb payloads, then sends the resulting node through the authenticated WhatsApp socket. The source explicitly states these inputs are designed to freeze, crash, or glitch recipient clients, including anonymous and group-wide effects.

AI rationale

This is a concrete, exported remote denial-of-service capability, not merely a noisy static signal. Its runtime invocation requirement does not negate the package’s explicit attack functionality.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

Exports constructors explicitly designed to crash or freeze WhatsApp clients.
Registers crash, overflow, anonymous, group-crash, and timebomb payload types.
Provides sendBugPayload, which sends a selected malicious payload to a caller-supplied JID.
The install hook only enforces a Node.js version; it is not the attack trigger.

Evidence against

No credential harvesting, shell execution, or unconsented local persistence found in inspected entrypoints.
Payload delivery requires an explicit runtime call to sendBugPayload.
