BGP and DNS infrastructure attacks¶

Attack pattern¶

BGP and DNS infrastructure attacks represent a critical threat vector that targets the fundamental systems responsible for internet routing and name resolution. These attacks exploit the interdependence between these two core protocols to disrupt services, intercept traffic, or redirect users to malicious destinations. By manipulating either BGP routing or DNS resolution, attackers can cause widespread internet disruptions, facilitate espionage, or enable financial fraud.

Why it works¶

Protocol interdependence: BGP and DNS are fundamentally interconnected. DNS provides name-to-IP resolution while BGP determines how to reach those IP addresses, creating multiple points of potential failure when attacked in combination.
Trust-based operations: Both protocols historically operate on a trust model where participants are assumed to be legitimate, making authentication and validation optional rather than mandatory.
Implementation complexity: The complexity of both protocols leads to implementation inconsistencies and vulnerabilities that attackers can exploit.
Partial security deployment: Security extensions like DNSSEC and RPKI are not universally deployed, creating security gaps that attackers can exploit.
Monitoring challenges: Detecting sophisticated attacks that span both protocols requires coordinated monitoring that many organisations lack.
Economic factors: The economic impact of successful attacks creates financial incentives for attackers while the cost of comprehensive protection deter defenders.
