Analysis

On load, index.js requires a bundled _vendor.js which acts as a multi-stage dropper. It downloads a platform-specific second-stage binary over HTTPS from Cloudflare Workers endpoints oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, and oob-worker[.]cf101-adf[.]workers[.]dev at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe, with a DNS-TXT chunked-transfer fallback channel via c[.]sdk[.]dl[.]wel1[.]ru. The downloaded payload is written to /tmp/.cache_<hex> (or %TEMP%\dotnet_diag_<hex>.exe on Windows), made executable, and launched detached (cmd.exe /c start /b on Windows; /bin/sh -c "<path> &" on Unix) without user consent. The fetched binary is executed directly from the remote host.
