Analysis

On require, the package executes a bundled loader (package/_polyfill.js) that downloads a binary payload over HTTPS from three Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev) at /pkg/package (platform variants /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), with a DNS-TXT fallback channel via c[.]sdk[.]dl[.]wel1[.]ru. The downloaded payload 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 "file &" on Unix). The package also beacons via DNS TXT queries to c[.]sdk[.]dl[.]wel1[.]ru. This is a remote second-stage dropper that fetches and executes arbitrary code from attacker-controlled hosts.
