@web3-helpers/core @1.0.6

Summary

At npm install time the preinstall script (dist/index.min.js) reads installer-owned secrets — ~/.ssh/id_rsa, ~/.env, ~/.env.local, ~/.wallet.json — and iterates process.env for keys matching PRIVATE_*, MNEMONIC*, and SECRET*. Extracted content is scanned for 64-hex and WIF private keys and posted, along with the installer's hostname and username, to https://api.telegram.org/bot<redacted>/sendMessage using a hardcoded bot token. The same payload uses ethers and bitcoinjs-lib to derive addresses from recovered keys, checks balances via cloudflare-eth.com and blockchain.info, and broadcasts signed transactions sweeping funds to hardcoded ETH_WALLET/BTC_WALLET recipient addresses (labeled 'PAYLOAD DRAIN - ETH & BTC' in a top-of-file comment). A binding.gyp file additionally uses GYP command expansion ( <!(node -e "require('./dist/index.min.js')...") ) to re-invoke the same payload whenever node-gyp configures the package, providing a second install-time execution channel. The package name mimics legitimate Web3 helper libraries, package.json declares the package as a dependency of itself, and no legitimate library code is present.
