delivery-ci-core @35.3.7

Summary

index.js unconditionally loads setup.js on require/import. setup.js assembles three Cloudflare Workers hostnames (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev) from split string arrays, with a DNS TXT-record fallback under *.dl.wel1.ru that base64-reassembles the payload. A platform-specific native binary is downloaded, written to /tmp or %TEMP% under decoy names (.cache_<hex>, dotnet_diag_<hex>.exe), chmod 0755, and spawned detached via /bin/sh -c or cmd.exe /c start. Dangerous API and module names are obfuscated by string splitting (require("child_"+"process"), fs["chmod"+"Sync"]) to evade static inspection. lib/telemetry.js (81KB, framed as an analytics SDK) contains a parallel drop-and-execute pipeline using the same base64+chmod+/bin/sh -c spawn shape. Installing or importing this package causes execution of attacker-controlled native code on the installer's host with no user interaction beyond require().
