On require of the package, index.js loads compat.js which reconstructs mirror hostnames via string-splitting joins (oob-worker.cf102-baf.workers.dev, cf99-9b3.workers.dev, cf101-adf.workers.dev, cf100-416.workers.dev) with a DNS TXT-record fallback under *.dl.well1.site, fetches a platform-specific binary via https.get, writes it to a disguised path under /var/tmp or %TEMP% (e.g..cache or dotnet_diag_.exe), chmods 0755, and spawns it detached via /bin/sh -c or cmd /c start. A second equivalent dropper is bundled in lib/telemetry.js (Buffer.from(chunks,'base64'), chmodSync 0o755, cp.spawn('/bin/sh',['-c',filePath+' &'])) as an alternate staging path. Hostname reconstruction via array-join fragments and library-load-time execution place this outside legitimate native-binary install patterns.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
