“The expansion and distribution of bots is a very powerful indicator of Emotet’s development in restoring its as soon as sprawling infrastructure,” Black Lotus Labs famous. “Each and every bot is a possible foothold to a coveted community and items a chance to deploy Cobalt Strike or ultimately be promoted to a Bot C2.”
