Talks
your contributions, today
Keynoting 0xcon in Johannesburg this year, I had the immense privilege of talking and sharing ideas about something that is dear to my heart. That is, giving back more than you take. And by giving back I don’t mean *just* doing research or writing tools. Instead, giving back includes things like writing documentation or even just teaching someone else! In my talk, “your contributions, today” I reflected on a current…

Four of those are DEF CON 29 talks, where two are main stage talks, one a demo labs talk and one…

This is a summary of our BlackHat USA 2020 talk. On some of our engagements, Szymon and I found ourselves on various networks vulnerable to; insecure, misconfigured, and often overlooked networking protocols. These included dynamic routing protocols (referred to as DRP‘s) and first hop redundancy protocols (referred to as FHRP‘s). We decided to focus on these two classes of networking protocols to manipulate traffic flows and identify non-conventional ways of…
