Analysis

On require, the package runs a bootstrap routine that downloads a binary payload over HTTPS from four Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe depending on platform. If HTTPS fails it falls back to reassembling a base64 payload from DNS TXT records under the domains sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, and net[.]dl[.]wel1[.]ru. The downloaded payload 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 "file &" on Unix). A stamp file (/tmp/.analytics_state or %TEMP%\analytics_state) throttles re-execution. The package also ships an 81KB decoy analytics SDK (lib/telemetry.js) that masks the downloader as telemetry.
