Automating AV signature generation
By Thomas Dullien
I finally get around to writing about our automated byte signature generator. It’s going to be a bird’s eye view, so if you’re interested you’ll have to read Christian’s thesis (in German) or wait for our academic paper (in English) to be accepted somewhere.
First, some background: One of the things we’re always working on at zynamics is VxClass, our automated malware classification system. The underlying core that drives VxClass is the BinDiff 3 engine (about which I have written elsewhere). An important insight about BinDiff’s algorithms is the following:
The Zynamics guys always have a different way of thinking. Great work again!
