A DNS-TXT fallback channel under sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru retrieves base64-encoded payload bytes across numbered TXT records and follows the same write-and-execute path, providing redundant covert delivery when HTTP egress is filtered. A TTL stamp file provides persistence between invocations. The package's advertised name bears no relation to the actual behavior.
