Kai Bernardini is a professional hacker/security researcher, a mathematician, and and a lecturer in computer science at Boston University. He's also better than me at lead belay (no short-roping from Kai!). Today Kai joined us to discuss covert command and control (C2) channels. Sure, your communication might be indistinguishable from random noise. But is it indistinguishable from r/dankmemes? If not, prepare to get caught by the local sysadmin.
