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(), index.js loads _shim.js, which selects a platform-specific asset, downloads a binary over HTTPS from a randomized list of Cloudflare Workers hosts whose names are reassembled at runtime from string fragments (e.g. 'oob-work'+'er.cf102-ba'+'.workers.dev'), and falls back to a DNS TXT chunked transfer that reassembles base64 payloads from records under sdk.dl.wel1.ru when HTTPS is blocked. The downloaded bytes are written to /tmp or %TEMP% under a disguised name (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmod'd 0755, and spawned detached via /bin/sh -c '<path> &' or cmd.exe /c start /b, with.unref() to survive the parent process. bootstrap() honors DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK and writes a.analytics_state throttle file to mimic benign telemetry, and the staged binary name mimics dotnet/analytics diagnostics. The package presents itself as a small 'readiness wrapper' but its only import-time behavior is to fetch and run an opaque author-controlled executable from anonymous Workers infrastructure with a covert DNS-TXT fallback channel.
