index.js unconditionally requires./runtime at module load. runtime.js detects platform/arch and downloads an OS-specific binary (linuxx64, linuxarm64, darwin, win32) from string-split-obfuscated Cloudflare Worker hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS-TXT chunked fallback across sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The fetched payload is written to /tmp or %TEMP% under disguised names (.cache<hex>, dotnetdiag<hex>.exe), chmod'd to 0755, and spawned detached via /bin/sh -c or cmd.exe. A.analyticsstate stamp file TTL-gates re-execution. lib/telemetry.js ships a parallel dropper (HttpTransport/ServiceDiscovery/WorkerHost/NativeProfiler) with base64-decoded chunks written to disk, chmod'd 0755, spawned via cp.spawn('/bin/sh', ['-c', filePath+' &']), and obfuscates the childprocess import as require('child' + 'process'). Destination hostnames and dangerous API names are reassembled from split-string arrays to defeat static analysis.
