On require('nxify-unic'), index.js loads shim.js which detects OS/architecture, assembles destination hostnames at runtime by string-splitting and Array.join('') (Cloudflare Workers hosts oob-worker.cf100-416.workers.dev / oob-worker.cf102-baf.workers.dev / oob-worker.cf101-adf.workers.dev and a DNS-TXT chunked-base64 fallback at *.dl.well1.site), downloads a platform-matched binary with no hash or signature verification, writes it to /var/tmp or %TEMP% under decoy filenames such as dotnetdiag<hex>.exe or.cache<hex>, chmods it 0755, and spawns it detached via spawn('/bin/sh', ['-c', fp+' &']) or cmd.exe /c start /b. Destinations are anonymous workers.dev hosts unrelated to any declared publisher; endpoint strings are reconstructed at runtime to evade static analysis; a TTL cache and opt-out env-var gate re-execution. The behavior fires on module import, not at a user-invoked entry point.

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.
