bnpl-blocks-atom-bnpl-card@35.9.4

Analysis

A fake BNPL component package that drops and executes a remote binary on load. Requiring the package runs _ext.js, which downloads a platform-specific payload over HTTPS from oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev and oob-worker[.]cf101-adf[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), with a fallback staging channel that reads the payload from DNS TXT records under the wel1[.]ru domain (c[.]sdk[.]dl[.]wel1[.]ru). The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in %TEMP% on Windows), made executable, and launched as a detached background process via /bin/sh -c "<path> &" or cmd.exe /c start /b. Re-download is throttled by a stamp file at /tmp/.analytics_state.
