Analysis

On require, the package loads _support.js, which fingerprints the host platform/arch and downloads a second-stage binary from Cloudflare Workers hosts (oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) at /pkg/package (or /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe per platform). If the HTTPS download fails, it falls back to DNS-tunneling the payload out of TXT records under c[.]sdk[.]dl[.]wel1[.]ru. The fetched binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in TEMP on Windows), chmod 755, and launched detached via /bin/sh -c "path &" or cmd.exe /c start /b, so it runs in the background and outlives the parent process. The package's index.js is a stub whose only real function is triggering this dropper.
