[Dailydave] C2

[Dan Guido]

I explicitly challenged this notion ("the defender's dilemma") in research
I presented a few years back (http://www.trailofbits.com/research/#eip).
Attackers have limited resources and can't afford to invest equally in
every potential opportunity for exploitation, persistence, C2, etc. You
start to make tradeoffs about which ones work in the most situations or
satisfy other requirements you have. It's as applicable to "APT" as it is
to mass malware.

It's exactly this line of thinking that led us to build Javelin (
javelinsecurity.com), which helps you measure and understand the efficacy
of common attacker strategies against your network. Our goal is to force an
attacker's dilemma, make *them* make the difficult decisions and the
expensive investments in new tools, training and systems.

Several other papers on the same topic from MSR/WEIS:
