Border Gateway Protocol (BGP) Hijacking is one of the many famous attacks hackers deploy to interfere with content delivery networks (CDNs). Hackers may also be capable of interfering with cloud hosting providers. Recently, almost all major cloud service providers like Google, Amazon, and GoDaddy have become victims of BGP Hijacking.How Does a BGP Function?
Before getting into the depth of how BGP hijacking occurs, it is important to delve into BGP. BGP is essentially a routing protocol that can connect several networks. This congregation of networks is known as an Autonomous System (AS). A routing protocol is used to transfer information or data packets across several networks.Typically, an AS consists of ISP providers, large tech enterprises, or in some cases, networks that belong to governments. Every AS receives a unique number responsible for controlling a specific set of IP ranges or spaces known as prefixes. Every AS displays the list of IP addresses they control and possible pathways to neighboring routers or Peers during data packet routing.
