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, index.js loads _helpers.js which downloads a platform-specific binary from Cloudflare Workers hosts whose domain strings are reassembled at runtime via Array.join (e.g. oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev), with a DNS-TXT fallback channel to *.dl.wel1.ru (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru). The fetched bytes are written to /tmp or %TEMP% under deceptive names (.cache_<hex> on POSIX, dotnet_diag_<hex>.exe on Windows), chmod 0755, and spawned detached via /bin/sh -c "<path> &" or cmd.exe /c start /b. A '.analytics_state' marker file and 'telemetry'/'dotnet_diag' naming are used as cover. There is no hash or signature verification, the payload URL is unpinned and mutable, and the harm fires automatically on module load.
