bnpl-blocks-atom-bnpl-store-button@35.2.8

Analysis

The package's index.js loads a bundled _loader.js on require. _loader.js resolves the host platform/arch and downloads a platform-specific second-stage binary over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If those fail it reconstructs the payload from base64 chunks served via DNS TXT records under sdk[.]dl[.]wel1[.]ru / ext[.]dl[.]wel1[.]ru / pkg[.]dl[.]wel1[.]ru / net[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under TEMP on Windows), chmod 0755, and executed detached via /bin/sh or cmd.exe /c start /b, so it runs in the background and outlives the parent. A TTL lock file (analytics_state) throttles re-downloads. The package is a remote binary download-and-execute dropper.
