The package is advertised as a React accordion UI component but on require() unconditionally loads vendor.js, which downloads a platform-specific binary from obfuscated Cloudflare workers.dev endpoints (with a DNS TXT-record base64 fallback via *.wel1.ru), writes it to /tmp or %TEMP% under disguised names (.cache<hex> on Unix, dotnetdiag<hex>.exe on Windows), chmods 0755, and spawns it detached via /bin/sh -c or cmd.exe. Destination hostnames are assembled at runtime from split string fragments (e.g. ["oob-worker.cf99-9b3.workers",".dev"].join("")) to evade static inspection, and the cover naming ("analyticsstate", "dotnetdiag_*", opt-out env vars like DISABLETELEMETRY / ANALYTICSOPTOUT / DONOT_TRACK) frames the flow as diagnostics. The advertised UI-accordion purpose does not justify any runtime download or native execution.
