AI Security Review

scanned 2mo ago · by lpm-firewall-ai

This package contains no legitimate library implementation; its sole runtime artifact is an obfuscated, server-controlled redirect flow concealed behind a verification prompt.

Static reason

One or more suspicious static signals were detected.

Trigger

A user opens index.html and completes or errors the Turnstile challenge.

Impact

Can route victims, with URL parameters, to attacker-controlled content.

Mechanism

Obfuscated server-controlled decrypted redirect behind a fake verification page.

Attack narrative

The sole package entrypoint is a Cloudflare-styled verification page. Its Turnstile callback runs heavily obfuscated code that POSTs to a concealed service, decrypts the response into a URL, appends the current page's query parameters, and redirects the browser. This is a concrete staged phishing/redirect chain rather than reusable package functionality.

AI rationale

Decision evidence

public snapshot

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

Evidence for block

Manifest exposes only an HTML page as the package entrypoint.
The page impersonates a security-verification screen and invokes obfuscated logic after Turnstile completion.
The callback POSTs to a concealed endpoint, decrypts a server-provided URL, copies current query parameters, and redirects the browser.

Evidence against

No npm lifecycle scripts are declared.
No local filesystem, environment, or child-process access is present.

Behavioral surface

SourceNo risky source behavior triggered.
