index.js unconditionally requires./setup.js, which on module load selects an OS/arch-specific asset path and downloads a binary from Cloudflare Workers hostnames assembled via split-string obfuscation (oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev), with a DNS-TXT base64-chunk fallback channel over sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. The downloaded bytes are written to a disguised temp filename (.cache_ on Unix, dotnet_diag_.exe on Windows), chmod 0755, and spawned detached via /bin/sh -c fp & or cmd.exe /c start /b. Destination hostnames are constructed at runtime by joining fragmented string arrays, and a TTL flag file throttles re-execution. Installing or requiring this package causes attacker-controlled code to run on the installer's host.
