boxy-sticky-providers @35.1.5

Summary

On require() of the package, _init.js downloads a platform-specific binary from Cloudflare Workers hosts whose names are reassembled at runtime from split-string arrays (oob-worker.cf101-adf.workers.dev), with a DNS-TXT covert-channel fallback via sdk.dl.wel1.ru. The payload is staged to /var/tmp/.cache_<hex> on Unix or a dotnet_diag_<hex>.exe path on Windows, chmod 0755'd, and spawned detached through /bin/sh -c or cmd /c start. There is no hash or signature verification, the destinations are unrelated to any declared publisher, and the code uses disguised filenames, cooldown markers, and DISABLE_TELEMETRY/DO_NOT_TRACK kill-switches. Anyone who installs and require()s this package executes attacker-controlled bytes on their machine.
