looking for botnets...
I am looking for some malware which makes machines part of botnets but that communicate to their C&C servers using ICMP, DNS or other protocols "abused"
For example the Backdoor.Fonamebot (http://www.symantec.com/business/security_response/writeup.jsp?docid=2007-062908-2551-99) is one who receive commands from c&c via DNS query packets
Thanks a lot to all of you
All the best
