A DNS TXT-record fallback reassembles a base64 payload from subdomains under dl.wel1.ru (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru) when HTTPS fails. Package metadata claims 'Common TypeScript definitions' and the name mimics the 'dolyame' brand, but the tarball ships only the dropper plus a 76KB lib/telemetry.js sibling; author field is empty. The runtime-constructed destinations, hidden staging path, detached exec, and DNS-TXT fallback are intentional evasion.
