Excerpt from the text quoted above: 2.3. For a DDoS attack to succeed more than once, the launch points must remain anonymous. Therefore, forged IP source addresses are used. From the victim's point of view, a DDoS attack seems to come from everywhere at once, even from many IP addresses that are unallocated or otherwise invalid. How many people have seen "forged" spoofed IP addresses being used for DOS attacks lately?
it does still happen... I've not run the numbers for our reactions to say '50% spoofed/50% non-spoofed' but it certainly seems like 'more' are non-spoofed lately. This could be a simple swing of the pendulum, or other 'better' things like more people egress filtering. -Chris
