Requiring the package loads vendor.js, which reconstructs remote hosts from array-join fragments (resolving to Cloudflare Workers hosts such as oob-worker.cf*.workers.dev and a *.dl.wel1.ru fallback discovered via DNS-TXT), downloads a platform-specific binary over HTTPS with no hash or signature verification, writes it to /tmp or %TEMP% under a disguised name (.cache<hex> on Unix, dotnetdiag<hex>.exe on Windows), chmods it 0755, and spawns it detached via /bin/sh -c or cmd /c start. A TTL stamp is used to avoid re-fetching on subsequent loads. The advertised purpose (a BNPL button UI set) has no legitimate need for downloading and executing an external binary, and the destination hosts are obfuscated to defeat static string scanning.

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.
