Owning the Routing Table - Part II

Explore an advanced OSPF attack that exploits a newly discovered protocol ambiguity, allowing an attacker to control routing tables across an entire autonomous system. Dive into the technical details of this powerful routing attack, presented at Black Hat USA 2013 as a sequel to the 2011 "Owning the Routing Table" talk. Learn about the vulnerability's impact on major router vendors, potential exploit scenarios including black holes and network cuts, and ongoing multi-vendor efforts to address this security issue. Gain insights into Internet routing, OSPF fundamentals, and the attacker's perspective through detailed illustrations and real-world examples. Understand the implications for network security and discover how a single compromised router can lead to widespread routing table manipulation.
