delivery-ci-unit@35.9.3

Analysis

delivery-ci-unit@35.9.3 is a remote-code-execution dropper. Requiring the package runs lib/_loader.js, which downloads a platform-specific binary payload over HTTPS from multiple Cloudflare Workers hosts (oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe. If HTTPS is blocked it falls back to a DNS TXT chunked base64 transfer from c[.]sdk[.]dl[.]wel1[.]ru. The downloaded payload is written to a hidden temp file (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c '... &' on Unix). The package's declared API (DeliveryCiUnit class) is a decoy; the loader runs automatically on require.
