Analysis

On require, the package loads a bundled module that fingerprints the OS/architecture and downloads a platform-specific binary payload over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe. If HTTPS fails it falls back to a DNS TXT chunked-transfer channel under *.wel1[.]ru (c[.]sdk[.]dl[.]wel1[.]ru, sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded binary is written to /var/tmp/.cache_<hex> (or %TEMP%\dotnet_diag_<hex>.exe on Windows) and executed as a detached background process via cmd.exe /c start /b or /bin/sh -c. The package is a remote binary download-and-execute dropper.
