BGP & Routing Attacks

BGP stitches the internet together — tens of thousands of independent networks deciding, announcement by announcement, where every packet goes. It runs almost entirely on trust: an autonomous system says "this address space is reachable through me" and the rest of the internet believes it. That trust is route hijacking and route leaks — how BGP picks paths, how an attacker bends those paths to swallow other people's traffic, the incidents that made it real, and how RPKI started to fix it.
