Traces how BGP carries reachability between autonomous systems: prefixes, AS_PATH, eBGP versus iBGP, the route-selection algorithm, and why convergence after a failure can take seconds to minutes.
Traces how the internet's routing protocol came to trust whatever it is told, the incidents that exploited that trust from 1997 to today, and the RPKI, ROV, and MANRS work trying to close the gap.
Traces two targeted BGP hijacks that stole cryptocurrency: the 2018 Amazon Route 53 attack on MyEtherWallet and the 2022 KlaySwap incident, and how a short hijack plus a fraudulent certificate intercepts HTTPS traffic.
How BGP went from a 1989 lunch sketch to the protocol every network on Earth depends on: EGP's replacement, BGP-4 and CIDR, the routing table's relentless growth, and the security retrofits that came decades too late.
