Hacker hijacks Orange Spain RIPE account to cause BGP havoc

Orange Spain suffered an internet outage today after a hacker breached the company's RIPE account to misconfigure BGP routing and an RPKI configuration.

The routing of traffic on the internet is handled by Border Gateway Protocol (BGP), which allows organizations to associate their IP addresses with autonomous system (AS) numbers and advertise them to other routers they are connected to, known as their peers.

These BGP advertisements create a routing table that propagates to all other edge routers on the internet, allowing networks to know the best route to send traffic to a particular IP address.
