While security issues abound on the Internet, the absolute high ground in cyber space consists of the routing plane, which controls where and how traffic flows or if it even flows at all.  This control is based on the Border Gateway Protocol (BGP), which is a trust-based system involving almost 50,000 entities on the global Internet.  This core component of our shared infrastructure is under attack as state actors and criminals are now using it to target their adversaries and victims.  This talk will review some of the hijacking techniques we first observed in 2013 and discuss the use of big data global analytics for finding malicious behavior in the constant flood of routing updates.  This is the first algorithm we are aware of that attempts to find all of routing hijacks on the global Internet and, by necessity, must do so without any a priori knowledge of the correct state of routing at every moment in time. We'll use our methodology to summarize all the hijacks observed in 2013 and include examples of more recent ones.  Finally, we'll briefly review some of the proposals for strengthening the BGP protocol and their limitations to global adoption.
