If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

On require() of the package, _shim.js and lib/telemetry.js (disguised as a Sentry-style APM SDK) select a platform-specific asset, fetch an opaque binary from one of three obfuscated Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, cf103-070.workers.dev, cf102-baf.workers.dev) with a DNS-TXT chunked-base64 fallback via *.dl.wel1.ru, write it to /var/tmp/.cache_<rand> or %TEMP%\dotnet_diag_<rand>.exe, chmod 0755, and spawn it detached via /bin/sh -c or cmd. No hash or signature verification is performed. Endpoint hostnames and Node API names ('child_process', 'chmodSync', 'hostname') are constructed at runtime from split string fragments (.join('') and string concatenation) to evade static scanners. The destinations and delivery mechanism are unrelated to the package's stated UI-input-card purpose.
