Requiring the package triggers async initialization in support.js that downloads a platform-specific binary (linux x64/arm64, darwin, win32) from Cloudflare Workers hosts and *.dl.wel1.ru mirrors whose hostnames are assembled at runtime via array.join("") string splits, with a DNS-TXT fallback resolver for the same domain family (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru). The fetched bytes are written to /var/tmp/.cache<rand> on Unix or TEMP/dotnetdiag<rand>.exe on Windows, chmodded 0755, and spawned detached via /bin/sh -c or cmd /c start. childprocess is loaded via require("child" + "process") and fs.chmodSync via fs["chmod" + "Sync"] to evade static scanners. The package advertises itself as a React UI component library; none of this behavior relates to that purpose. Attacker-controlled binaries with disguised on-disk names (dotnetdiag,.cache) execute on every require() of the package.
