Hi,

I see nowadays two kind of kol/avalanche double-fast-flux botnets.

One is based on compromised Windows system with port forwarding to a
specified avalanche nginx host (e.g. malware dcb73b459437a741f9e0bff7e9d23976).

Another variant is based on Linux systems with nginx as first proxy instance.
e.g. the identity theft malware family urlzone uses
chicwhite.com.		165	IN	A	182.19.54.114
chicwhite.com.		165	IN	A	219.95.142.217
chicwhite.com.		165	IN	A	219.141.171.70
chicwhite.com.		165	IN	A	175.136.253.153

or in the last days
