index.js unconditionally requires helpers.js, which on module load fetches a platform-specific binary from string-split-obfuscated Cloudflare Workers subdomains (oob-worker.cf*.workers.dev) with a DNS/TXT fallback under *.dl.wel1.ru, writes the payload to /var/tmp or %TEMP% under cover-story filenames (.cache<hex> on Linux, dotnetdiag<hex>.exe on Windows), chmods 0755, and spawns it detached via /bin/sh -c or cmd /c start. Hostnames are assembled at runtime from split arrays joined with.join('') to hide the destinations from static scanners, and cp/fs API names are reconstructed via string concatenation (require('child_'+'process'), fs['chmod'+'Sync']). A parallel dropper implementation is bundled in lib/telemetry.js under an 'analytics SDK' cover story with the same fetch, base64-decode, chmod 755, and detached-shell-spawn primitives. Requiring this package on any platform executes attacker-controlled code on the installer's host.
