Shift SDK v4 — trading API client (Shift Forex scoped build)
This report shows the evidence for @shiftmarkets/shift-sdk-v4@1.0.77, the only known version.
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package contains a concrete, automatic, non-package-aligned host-fingerprinting exfiltration chain at install time. The normal SDK entrypoint does not justify this hidden telemetry.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall
Impact
Unconsented disclosure of workstation/CI identity, local network addresses, paths, usernames, and environment metadata.
Mechanism
silent install-time host reconnaissance and HTTP exfiltration
Attack narrative
On installation, the postinstall hook invokes dist/recon.js. It gathers hostname, username, home directory, current directory, internal interfaces/IPs, DNS domain, CI indicators, and all environment-variable names, then sends the JSON payload to a hard-coded external IP over HTTP. Error suppression keeps the install successful if collection or transmission fails.
AI rationale

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json runs dist/recon.js in postinstall.
- dist/recon.js collects host, user, home, cwd, network IPs, CI and environment-variable names.
- The postinstall probe POSTs this fingerprint to 138.68.108.20:80/cb.
- dist/recon.js silently suppresses errors and postinstall uses `|| true`.
Evidence against
- dist/index.js is a user-configured trading API client; its endpoint is supplied by the caller.
- recon.js does not transmit environment-variable values or write local files.
