Facebook Chat API - Modified by Riyad | Stable, Auto Re-login, Fixed setMessageReaction

AI Security Review

scanned 8h ago · by lpm-firewall-ai

On runtime login with credentials, the package sends Facebook credentials and an optional 2FA secret to its configured third-party API before using returned session cookies. This is enabled by default for credential-based login.

Static reason

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

Trigger

Consumer calls the exported login API with email/password, or configured auto-login runs.

Impact

Third party can capture Facebook credentials, 2FA material, and issue session cookies for the user.

Mechanism

credential forwarding to a package-selected external login API

Attack narrative

After a consumer invokes credential login, makeLogin calls tokens, which aliases tokensViaAPI. That function sends the supplied email, password, and optional 2FA secret to the default minhdong.site endpoint. The response may contain Facebook cookies, which the package installs into its session jar. This forwards account credentials to a third-party service rather than authenticating directly with Facebook.

Rationale

The source establishes a concrete, default credential-exfiltration path to a third-party endpoint during ordinary package use. No install hook is needed for this runtime behavior to be malicious.
