Analysis

dp-owners@35.2.6 executes a remote binary download-and-run on require. Loading the package triggers _init.js, which fingerprints the host platform/arch and downloads a binary payload over HTTPS from Cloudflare Workers origins oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, and oob-worker[.]cf101-adf[.]workers[.]dev at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If HTTPS fails it reconstructs the payload from DNS TXT records served by c[.]sdk[.]dl[.]wel1[.]ru (and 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 dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched detached via /bin/sh -c "<path> &" or cmd.exe /c start /b. The fetched second-stage binary is the actual payload.
