My current understanding: -Bad guys announce space for Facebook / Amazon / banks / whatever -Some traffic for high-value destinations gets diverted to Bad Guys -Bad Guys do Bad Things By focusing on BIAS-providers to secure *their own* routes, aren't you stopping the Bad Guys from hijacking eyeball space, rather than high-value destination space? Is there a useful attack vector where the return traffic from Facebook to my residential CPE is diverted via the Bad Guys? My instinct is that the quick win comes from high-value targets (or their ISPs) *generating* ROA, and ensuring that the BIAS providers are *validating* (ROV) that their customer traffic is going to the "real" Facebook. I'm struggling with how much issuing ROAs for residential broadband ranges helps with this particular problem, and why - any free clues or pointers to reading gratefully received. Thanks, Tim.
