Malicious code in bnpl-blocks-atom-bnpl-dolyame-button (npm)

On require, index.js loads setup.js which selects a platform-specific binary path for linux/darwin/win32, downloads it over HTTPS from hardcoded Cloudflare Workers hostnames (oob-worker.cf103-07.0.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT chunked fallback via sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, writes the payload to a disguised temp path, chmods it 0755, and spawns it detached via /bin/sh -c or cmd /c start. Destination hostnames and sensitive API names (childprocess, chmodSync) are reconstructed at runtime from arrays of string fragments to defeat string scanners. Opt-out environment variables (DISABLETELEMETRY, ANALYTICSOPTOUT, DONOTTRACK) and a benign 'analytics_state' filename are used as cover. There is no pinning, no signature check, and the destinations are unrelated to the package publisher. Installing or requiring the package causes an attacker-controlled binary to run on the host.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
