Analysis

On require, this package downloads a binary payload over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at platform-specific paths (/pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), with DNS-TXT fallback discovery via sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru. The fetched binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in %TEMP% on Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c '<path> &' on Unix). The download-and-execute runs automatically when the module is imported, with no user action beyond installing/requiring the package.
