bnpl-blocks-atom-bnpl-notification@35.3.8

Analysis

The package is a decoy wrapper whose index.js loads a bundled runtime (lib/telemetry.js, _runtime.js) on require. The runtime downloads a platform-specific binary payload over HTTPS from three Cloudflare Workers hosts (oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe, with a fallback that retrieves the payload in base64 chunks via DNS TXT queries to c[.]sdk[.]dl[.]wel1[.]ru (and sdk/ext/pkg/net[.]dl[.]wel1[.]ru per platform). The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched as a detached background process via /bin/sh -c '... &' or cmd.exe /c start /b. Execution is rate-limited by a timestamp file (/tmp/.analytics_state). This is a remote binary download-and-execute dropper with a DNS-based fallback channel.
