If HTTPS mirrors fail, a DNS-TXT fallback channel queries c.<domain> at sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru for a chunk count and reassembles base64-encoded payload chunks from N.<domain> TXT records. A second file lib/telemetry.js contains an unreferenced variant of the same dropper. The Cloudflare Workers and wel1.ru destinations are unrelated to any legitimate Sentry infrastructure, and the package's advertised functionality is a cover story around the dropper.\n\n## Source: ghsa-malware (f76cb55af9e854ca5d57e6b318ae84ac06c517b98e7628117cc949f69c5c84fc)\nAny computer that has this package installed or running should be considered fully compromised.
