RE: Identifying Malware in Outbound Traffic

["David Gillett" <gillettdavid () fhda edu>]

  Get yourself a copy of "Extrusion Detection" by Richard Bejtlich.  (And
seriously consider some of his other books, too.)  Every serious virus
outbreak we've seen here walked on a laptop (if we know where it came
from...), but was caught by examining the traffic trying to *leave* our
network (and either "phone home" or try to infect the rest of the
Internet...).

Subject: Identifying Malware in Outbound Traffic

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
