Analysis

On require, the package loads _support.js, which fingerprints the host platform/arch and downloads a remote binary over HTTPS from Cloudflare Workers C2 hosts (oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe. If the HTTPS fetch fails it falls back to a DNS TXT exfil channel under the wel1[.]ru domain (sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded payload is written to /var/tmp/.cache_<hex> (or %TEMP%\dotnet_diag_<hex>.exe on Windows), chmod 755, and executed detached via /bin/sh -c or cmd.exe /c start /b, so it outlives the parent process. A timestamp marker file (.analytics_state / analytics_state) throttles re-execution.
