I've yet to see a business need for BotNet clients to run successfully ;)Perhaps application filtering for the Drone control protocol?
Much better done in a controlled lab environment than on a production network. The bot connecting to a captive server isn't what I'd consider "successful."
Drone armies, although massive are nothing special. They are usually built of the same 2-4 Trojan horses that are big at that time.
Yep, but the point I'm making is that we have widespread infections inside companies "protected" by firewalls- while the firewalls are perfectly capable of supporting sane security policies that would block the 98th percentile of these things.
Filtering the traffic for their control protocol, on whatever port, or their repetetive echo commands/ special connections to IRC servers under certain IRC names or nickname/ident/name pattern-combinations is pretty easy to do when you come to think about it.
