On require, index.js loads _loader.js which selects a platform-specific binary path, fetches bytes from obfuscated Cloudflare Workers endpoints (oob-worker.cf102-baf.workers.dev, cf100-416/cf103-070/cf99-9b3.workers.dev) with a DNS TXT-record fallback channel across numbered subdomains of dl.well1.site (tin, tina, ldr, win) that reassembles a base64 payload. The downloaded bytes are written to /tmp or %TEMP% under disguised names (.cache_<rand>, dotnet_diag_<rand>.exe), chmod'd to 0755, and spawned detached via /bin/sh -c or cmd.exe /c start. Hostnames and API names are reconstructed via split-string joins (e.g. ['tin.','dl.well1.si','te'].join(''), require('child_'+'process')) to evade static analysis. A parallel implementation of the same dropper is shipped as lib/telemetry.js under an 'analytics SDK' cover story, with identical DNS-TXT reassembly, chmod 0755, and detached /bin/sh execution.

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.
