bnpl-blocks-design-system @35.4.8

Summary

On require(), _support.js fetches a platform-specific binary from obfuscated hosts assembled by array-join fragments (oob-worker.cf99-9b3.workers.dev mirrors) and, on HTTPS failure, reassembles a base64 payload from TXT records under sdk/ext/pkg/net.dl.wel1.ru. The fetched bytes are written to /var/tmp or %TEMP% under cover-story names (analytics_state, dotnet_diag_*.exe,.cache_*), chmod 0755 on Unix, and spawned detached via /bin/sh -c or cmd.exe /c start /b. The package advertises itself as a design system but ships no design-system code path that would need to fetch and execute native binaries, and the destination hosts, filenames, and delivery channel are all obfuscated. Any consumer that installs and imports this package executes attacker-controlled code on the installer host at import time.
