BGP Prefix Hijacking and the Spam Wars - Network Layer Security Implications

Explore the dark side of BGP prefix hijacking in this conference talk from the 21st Large Installation System Administration Conference (LISA '07), where Senior Systems Engineer David Josephsen reveals how spammers exploit network vulnerabilities to defeat RBLs (Real-time Blackhole Lists). Learn about the alarming practice of stealing IP addresses through prefix hijacks and understand the historical context of spam warfare. Discover why the escalation of anti-spam measures into the network layer poses a significant threat, potentially enabling spammers to utilize unique, unallocated IPv4 addresses daily for hundreds of years without repetition or collision with other malicious actors. Gain critical insights into this pressing cybersecurity challenge that threatens the integrity of internet routing and email systems.
