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

Summary

The package's main ( index.js ) requires ./_loader at module load, causing _loader.js to download a platform-specific native executable from hardcoded Cloudflare Workers hosts (oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev) whose hostnames are reassembled at runtime via Array.join string splitting to evade static scanners. If HTTPS fetches fail, a secondary channel retrieves base64-encoded chunks from DNS TXT records under *.dl.wel1.ru and reassembles them into the binary payload. The downloaded bytes are written to /tmp or %TEMP% under disguised filenames ( .cache_<hex> , dotnet_diag_<hex>.exe ), chmod'd to 0755 on Unix, and spawned detached via cp.spawn("/bin/sh", ["-c", fp + " &"]) or spawn("cmd",...) on Windows. No hash or signature verification is performed. Any require() or import of this package triggers full-host remote code execution. A second file, lib/telemetry.js , is not on the auto-executed graph in this version but contains structurally identical dropper primitives (base64 buffer to /bin/sh -c filePath & , chmod 0755, cp.spawn), mirroring the active loader.
