The main entry index.js requires./runtime.js, which at load time assembles hostnames from split string arrays (e.g. 'oob-worker.cf101-adf.workers.dev' and 'sdk.dl.wel1.ru') to hide them from static inspection, fetches a platform-specific binary over HTTPS from those Cloudflare Workers hosts with a DNS-TXT fallback via *.dl.wel1.ru, writes it to a masqueraded path (/var/tmp/.cache<uid> or %TEMP%/dotnetdiag<uid>.exe), chmods it 0755, and detach-spawns it via cp.spawn('/bin/sh', ['-c', fp + ' &'], {detached:true}) or the cmd equivalent on Windows. A TTL marker suppresses re-execution. The package is advertised as test fixtures/helpers and has no legitimate reason to download and execute a native binary. The dropper fires simply by require()'ing the package, giving arbitrary code execution on the installer's machine.
