On require(), platform.js reconstructs destination hostnames from split-string arrays (e.g. 'oob-worker.cf103-070.workers.dev' assembled from ['oob-w','ork','er.cf103-070.','worker','s.','dev']) and downloads an unpinned platform-specific binary via https.get over a set of anonymous *.workers.dev hosts (oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS-TXT base64 fallback resolved through *.dl.well1.site (e.g. 'tin.dl.well1.site' assembled from ['tin.dl.well1.','si','te']). The downloaded bytes are written to /var/tmp/.cache on Linux or to the Windows TEMP directory as dotnet_diag_.exe, chmodded 0755, and spawned detached via spawn('/bin/sh', ['-c', fp + ' &'], {detached:true}) or cmd /c start. A 'telemetry/analytics' cover story with a DO_NOT_TRACK opt-out and an analytics_state cooldown marker is layered around the drop-and-exec. No hash or signature verification is performed on the fetched binary.

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.
