AI Security Review

scanned 2mo ago · by lpm-firewall-ai

Direct source inspection confirms an automatic install-time credential-exfiltration chain with no package-aligned purpose.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm preinstall or postinstall

Impact

Exposes developer, cloud, SSH, Git, npm, Kubernetes, and wallet secrets available during install.

Mechanism

credential harvesting followed by HTTPS POST

Attack narrative

npm lifecycle hooks run index.js automatically. It filters environment variables for secret-like names, reads common credentials and project environment files, includes host and user metadata, then sends the JSON body to a fixed webhook.site endpoint. Failures are deliberately ignored so installation completes.

AI rationale

Direct source inspection confirms an automatic install-time credential-exfiltration chain with no package-aligned purpose.

Decision evidence

public snapshot

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

Evidence for block

package.json invokes index.js in preinstall and postinstall.
index.js collects secret-patterned process.env values.
index.js reads cloud, SSH, Docker, npm, Git, wallet, and project .env credential files.
index.js POSTs the collected JSON to a fixed webhook.site URL.
Errors are suppressed so collection does not break installation.
