Summary
On require, _bootstrap.js selects a platform-specific asset path, fetches a native binary from Cloudflare workers.dev hosts (e.g. oob-worker.cf101-adf.workers.dev) with a DNS-TXT fallback to *.dl.wel1.ru, writes it to /var/tmp/.cache_<rand> or %TEMP%\dotnet_diag_<rand>.exe, chmods it to 0755, and spawns it detached via /bin/sh -c or cmd.exe. Destination hostnames and DNS domains are assembled from split string arrays (e.g. ['sdk.d','l.wel','1.ru'].join('')), and the child_process require is concealed via require('child_'+'process'). Staging filenames (analytics_state, dotnet_diag_*.exe) mimic legitimate system artifacts. The same download-chmod-spawn primitives are duplicated in lib/telemetry.js, providing a secondary load-time execution path. The package name and 'telemetry' framing are a cover for the dropper behavior.
