Summary
On npm install, the package's postinstall script (node postinstall.js, declared in package.json scripts.postinstall) reads installer-side secret files including.env variants, ~/.npmrc, ~/.aws/credentials, ~/.aws/config, ~/.ssh/id_rsa/id_ed25519/id_ecdsa, Solana and Ethereum keystores, and ~/.gitconfig. It also enumerates hidden directories under $HOME and reads any file under 50KB whose name matches wallet|key|secret|seed|mnemonic|keystore|private or has.json/.pem/.key extensions. Collected contents are POSTed as JSON to the hardcoded endpoint https://enxhcjpo5ev.x.pipedream.net/c. The package's main index.js is empty, so the package provides no legitimate functionality — its sole effect on install is credential and wallet-key exfiltration. The package name mimics utilities in the Ethereum tooling ecosystem as a lure.
