delivery-ci-unit @35.9.3

Summary

On require of the package, index.js loads _loader.js, which reconstructs attacker-controlled hostnames from split-string fragments (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, plus DNS TXT chunked-base64 fallbacks at sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru), fetches a platform-specific binary over HTTPS, writes it to /tmp/.cache_<hex> on Unix or TEMP\dotnet_diag_<hex>.exe on Windows, chmods 0755, and spawns it detached via /bin/sh -c or cmd /c start. No signature or hash verification is performed; filenames masquerade as system caches; a TTL marker rate-limits execution; environment-variable checks are used as evasion; and a DNS TXT covert channel serves as a fallback delivery path. The fetch host is reconstructed at runtime with no legitimate purpose, and the destinations are not the package's publisher.
