Analysis

The package's main entry (index.js) loads a bundled dropper (_vendor.js) on require. The dropper downloads a platform-specific binary payload over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe, with a DNS TXT-record fallback channel using domains sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, and net[.]dl[.]wel1[.]ru. The downloaded payload is written to /tmp (or %TEMP% on Windows) under a random name (.cache_<hex> or dotnet_diag_<hex>.exe), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c "<path> &" on Unix). A timestamp marker file suppresses re-execution for a few hours.
