Summary: Malicious code in ckcc-protocol (npm)

Details: Source: amazon-inspector (3ebcdc07616ec6ab418a9005e1486d05f3753dc4d37f6ce61c5daed495d31e25) The npm package [email protected] typosquats the legitimate Coldcard ckcc-protocol tool and ships no functionality (index.js exports {}). Its package.json declares a postinstall script that runs automatically on npm install. The postinstall reads a fixed set of installer-side secret files, including ~/.env*, ~/.npmrc, ~/.aws/credentials, ~/.ssh/id_rsa, ~/.ssh/id_ed25519, ~/.ssh/id_ecdsa, ~/.config/solana/id.json, and ~/.ethereum/keystore, plus any dotfile whose name matches /wallet|key|secret|seed|mnemonic|keystore|private/i. It bundles the collected file contents together with os.hostname() and os.userInfo().username into a JSON payload and POSTs it via https.request to webhook.site/5c5ad6cb-62df-4ea5-9dfb-2c447920ddc4. The destination is an attacker-controlled request-capture endpoint, not the legitimate Coldcard project.
