Analysis

On require, the package loads a bundled bootstrap that downloads a platform-specific binary from Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe, with a DNS-TXT fallback channel via c[.]sdk[.]dl[.]wel1[.]ru. The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under %TEMP% on Windows), made executable, and launched as a detached background process. This is a multi-stage remote binary dropper that fetches and executes an arbitrary second-stage payload at install/require time.
