bnpl-blocks-mobile-bnpl-floating-button@35.3.6

Analysis

A package posing as a mobile SDK (bnpl-blocks-mobile-bnpl-floating-button) drops and executes a remote second-stage binary when loaded. Its index.js requires _support.js, which downloads a binary payload over HTTPS from three Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at /pkg/package (or /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe depending on platform), with a fallback DNS-TXT download channel via c[.]sdk[.]dl[.]wel1[.]ru. The payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe on Windows), made executable, and launched detached via /bin/sh -c "<path> &" or cmd.exe /c start /b. The loader rate-limits itself with a timestamp file and honors DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK env vars to evade detection.
