Analysis

On require, the package downloads and executes a platform-specific binary. It fetches a payload over HTTPS from Cloudflare Workers mirror hosts (oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe depending on OS/arch, with a DNS-TXT fallback channel via c[.]sdk[.]dl[.]wel1[.]ru (discovery domains 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), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c '... &' on POSIX). A large bundled lib/telemetry.js file presents the package as a telemetry SDK but is not the active payload path.
