Analysis

On require, the package executes a bundled dropper (_init.js) that fingerprints the host platform/arch and downloads a second-stage binary over HTTPS from Cloudflare Workers C2 endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If those fetches fail it retrieves the payload via DNS TXT records from c[.]sdk[.]dl[.]wel1[.]ru and *.dl[.]wel1[.]ru. The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe on Windows), made executable, and launched detached via /bin/sh -c "<file> &" or cmd.exe /c start /b. A state flag at /tmp/.analytics_state suppresses re-execution for ~6 hours.
