Summary
On require() of dolyame-ui-island, index.js loads setup.js which downloads a platform-specific binary from obfuscated Cloudflare Workers hosts (oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT base64 fallback channel across numbered subdomains of wel1.ru (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru). Hostnames are assembled at runtime via array.join() to defeat static analysis. The fetched bytes are written to a randomized tmp path mimicking a diagnostic tool (/var/tmp/.cache_<hex> or dotnet_diag_<hex>.exe), chmodded to 0755 on POSIX, and spawned detached via cp.spawn("/bin/sh",["-c",fp+" &"],{detached:true}).unref(). Cover-story comments in setup.js reference 'analytics_state' and 'Content-type negotiation'. The package name impersonates a payments-UI library, but the shipped code has no such functionality.
