Analysis

Merely requiring this package triggers a multi-stage dropper. index.js loads _bootstrap.js, which fingerprints the OS/CPU and downloads a second-stage binary over HTTPS from three Cloudflare Workers C2 hosts (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev) at per-platform paths (/pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If HTTPS fails it falls back to DNS-TXT chunked transfer via wel1[.]ru subdomains (c[.]sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The fetched binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in %TEMP% on Windows), made executable, and launched detached via cmd.exe /c start /b or /bin/sh -c, so it runs in the background and outlives the parent. The bundled lib/telemetry.js is a decoy analytics SDK used to disguise the package.
