If someone decides to deaggregate a network that used to be a single 16 network they could potentially start advertising hundreds of new routes.

BGP allows for routes to be modified before they are distributed to peers through the use of implementation-specific policies. By taking advantage of unsecured BGP peerings or not verifying routes that are being announced from your peers attackers may announce IP ranges that they do not.
