bigops-products-travel@35.7.1

Analysis

On require, the package's index.js loads _loader.js, which immediately downloads a platform-specific second-stage binary over HTTPS from multiple Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe. If HTTPS fails it falls back to DNS-TXT tunneling via c[.]sdk[.]dl[.]wel1[.]ru (and sdk/ext/pkg/net[.]dl[.]wel1[.]ru per platform). The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in TEMP on Windows), chmod 755, and executed detached via /bin/sh -c or cmd.exe /c start /b, so it outlives the parent. The package's declared purpose (a travel provider class) is unrelated to this download-and-execute behaviour.
