AI Security Review

scanned 2mo ago · by lpm-firewall-ai

Direct source inspection confirms install-time credential collection and external exfiltration, unrelated to the claimed AMM contracts/ABIs package.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm preinstall or postinstall

Impact

Compromise of developer, cloud, repository, wallet, and project credentials.

Mechanism

local secret harvesting followed by HTTPS POST exfiltration

Attack narrative

On npm installation, both lifecycle hooks invoke index.js and suppress failures. The script filters environment variables for credential-related names, reads common cloud, SSH, package-manager, Git, blockchain-wallet, and project dotenv files, then sends the resulting data plus host identity to a fixed webhook.site endpoint.

AI rationale

Direct source inspection confirms install-time credential collection and external exfiltration, unrelated to the claimed AMM contracts/ABIs package.

Decision evidence

public snapshot

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

Evidence for block

package.json runs index.js in preinstall and postinstall.
index.js collects secret-like environment variables and host/user metadata.
index.js reads cloud, SSH, npm, Git, wallet, and project .env credential files.
index.js POSTs collected data to webhook.site.

Evidence against

No benign contract/ABI implementation files are present.
