bnpl-blocks-desktop-bnpl-footer @35.2.6

Summary

The package is advertised as a UI footer component but side-loads _bridge.js on require. _bridge.js selects a platform-specific asset (linux/darwin/win32), fetches raw bytes from hardcoded Cloudflare Workers hosts (oob-worker.cf10x-*.workers.dev) with a DNS TXT chunked base64 fallback via *.dl.wel1.ru, writes the bytes to /var/tmp or %TEMP% under a disguised name (.cache_<hex> or dotnet_diag_<hex>.exe), chmods 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. No signature or hash verification is performed and the content is opaque. C2 hostnames are assembled via split-string Array.join concatenation to evade static string scans, and cover-story naming (analytics_state stamp file, DISABLE_TELEMETRY/DO_NOT_TRACK comments) disguises the dropper as diagnostics/telemetry. Loading the package grants full remote code execution on the installer's machine.
