Analysis

On require, the package fingerprints the platform/arch and downloads a second-stage binary over HTTPS from Cloudflare Workers endpoints oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, and oob-worker[.]cf103-070[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If the HTTPS download fails, it falls back to retrieving the payload in chunked base64 via DNS TXT queries to c[.]sdk[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under the Windows temp dir), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c "path &" on Unix). A stamp file is written to /tmp/.analytics_state to throttle re-execution.
