At first I was pretty scared about this, thinking it affected the entire network, but now that I think I understand it it's not as bad.
Here's my understanding-- its basically like a 51% attack, but its not a 51% attack its just 1 transaction they are trying to change and they are trying to spread that to dominate the network as quick as possible.
So who loses? Whoever is the victim of that 1 transaction for the most part-- and the clear target would be the exchanges.
The DDos attacks almost seem like a distraction, or a synergistic attack - but the maleability issue seems to come from an intention to steal coins transaction by transaction.
You guys agree or what?
