[Dailydave] Adversary Simulation

[Paul Melson]

So are you aware of a criminal actor that uses Immunity's Innuendo in their attacks?  If not, then which adversary are you simulating?

The point to my obvious straw man is that if you really want to help your clients up their game in detecting and responding to real threats, shouldn't you study the actors that target their industry verticals and emulate their operations using the same tools and tactics they are known to choose?

I like to call it "Focused Training" - because penetration testing is more about education than anything else, but the WAY you do to that is by emulating and instrumenting some sort of adversarial process.

We go to some big financial company, usually super under-dressed for the cold because we live in Miami, and we install INNUENDO on a couple machines. Then we exfiltrate a few terabytes of data over whatever protocols are working and we work with the company to do a hardcore analysis of their detection systems for that sort of thing.

Sometimes the Alerts are useful, and sometimes not. For example, when you're doing DNS exfiltration, FireEye will alert on the weirdness of the DNS packets. But it has no idea who the infected endpoint is, because those DNS packets came from intermediary DNS servers! :)

And on the host, when faced with a new product, all the protection systems we've seen have not detected INNUENDO. Some of them detect injection, but you don't really need to do that. What if there is too much chaos on a big company's desktop for reputation-based protection systems to work?
