devplatform-spa-plugin-s3-module-loader@35.8.2

Analysis

On require, this package downloads a platform-specific binary payload over HTTPS from Cloudflare Workers endpoints oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, and oob-worker[.]cf99-9b3[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If the download fails it reconstructs the payload from chunked base64 DNS TXT records served from sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, and net[.]dl[.]wel1[.]ru. The downloaded binary is written to a hidden file (.cache_<hex> in /var/tmp, or dotnet_diag_<hex>.exe in the Windows temp directory), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c "<path> &" on Unix) so it runs independently of the parent. The package's declared S3-module-loader functionality is a stub; the real behaviour is remote binary download-and-execute at import time.
