bigops-api@35.8.8

Analysis

bigops-api@35.8.8 is a multi-stage dropper. Requiring the package immediately runs a loader that downloads a binary payload over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]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-chunked fallback from c[.]sdk[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c "fp &" on Unix). The loader also probes the local network for a sandbox marker before executing. The package's index.js is a stub with no real API functionality.
