On require of the package's main entry, helpers.js selects a platform-specific target path, fetches an opaque binary over HTTPS from author-controlled Cloudflare Worker subdomains (oob-worker.cf99-9b3.workers.dev, cf103-070/cf100-416/cf102-baf.workers.dev) with a DNS-based fallback to sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, writes the bytes to /tmp or %TEMP% under disguised names ('.cache', 'dotnet_diag_.exe'), chmods 0755 on Unix, and detached-spawns the file via '/bin/sh -c &' or 'cmd /c start'. C2 hostnames and sensitive API names (child_process, chmodSync) are assembled at runtime from split-string arrays joined with '' to defeat static analysis. A second copy of the same fetch → base64 → chmod 0755 → detached-spawn chain, with identical string-concatenation obfuscation of 'child_process', is bundled in lib/telemetry.js as a parallel dropper. Any installer that requires this package executes attacker-controlled binaries with the user's privileges.
