Hi Team,

Step 1 - Go to http://www.shadowserver.org/wiki/pmwiki.php/Involve/GetReportsOnYourNetwork . Sign up to get daily 
reports on your network. This will give you a view from the operational security community's monitoring of the 
"criminal cloud."

Step 2 - Install Bothunter - http://www.bothunter.net/ . This is a free tool with a "community action network" that 
works together find malware communicating into and out of your network.

This is an idea we've been playing around with a lot lately. I was hoping the experts here could give us some 
pointers to improve or modify our process.

We are looking at ways to find existing infections that have evaded anti-virus successfully within our network. 
We've started doing this by monitoring web traffic for anomalies that we think indicate an infection. For example 
searching for traffic to sites listed in the Malware Domain list. At a basic level this is finding some interesting 
results.

But I am curious are other people attempting similar things, if so how are they going about doing so? Any thoughts 
or recommendations would be appreciated.

Thanks,
Helly
