🛡️ MAL-2026-4249 — truffle-config-helper

Malicious code in truffle-config-helper (npm)

Source: amazon-inspector

On npm install, the package's postinstall hook (package.json line 13) issues an HTTPS GET to rqnyz-2605-7280-7--2000-c51.run.pinggy-free.link/npm/-/binary/telemetry — a free public reverse-tunnel service providing mutable, anonymous infrastructure — and pipes the entire response body directly into child_process.exec with stdio silenced. There is no integrity check, no version pinning, and no inspection of the fetched payload; whoever controls the tunnel can execute arbitrary code on the installer's machine. The package's advertised purpose is a thin wrapper exposing ethers.getDefaultProvider (138 bytes in index.js), which functions only as a cover story for the dropper. The package name and author metadata (truffle-config-helper, Web3 Developer Tools <[email protected]>, repo github.com/web3/truffle-config-helper) impersonate the Truffle/web3 ecosystem to attract installs from blockchain developers.
