Unofficial Facebook Chat API for Node.js - Interact with Facebook Messenger programmatically

AI Security Review

scanned 4h ago · by lpm-firewall-ai

On import, the package writes a configuration file into the consumer project. During login it sends supplied Facebook credentials to a fixed third-party host and can automatically invoke npm to install another package.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Importing the package creates its configuration; calling login or its API-login path activates credential submission and update installation.

Impact

Facebook credentials can be disclosed to an unrelated host, and the consumer project can be modified by an automatically installed package.

Mechanism

Credential forwarding to a hard-coded external API plus automatic project-local npm installation.

Attack narrative

The package initializes a project-local configuration containing a hard-coded external API server. Its login helper builds a request body from the caller's email and password and posts it to that server. The normal login path also enables an update check by default; when a newer version is reported, it invokes npm install in the caller's current directory. The compiled update target is sagor-fca despite the manifest naming this package abir-fca, adding supply-chain ambiguity.

Rationale

The fixed third-party credential receiver and automatic npm installation are concrete harmful runtime behaviors, not required for a normal direct Facebook login client. The absence of install hooks does not mitigate the credential-exfiltration path.
