This is mincing words. It's an attack on bitcoin. Many major exchanges were shuttered while they dealt with it, for example.
It's certainly not an attack on not-bitcoin, so therefore it's an attack on bitcoin.

I would argue it was an attack on Bitcoin the ecosystem, due to an _oddity_ of Bitcoin the protocol. Bitcoin the idea is still fully alive. The attack worked from within Bitcoin, the network.
See, I can say ridiculous things too. Someone using bitcoins didn't follow protocol and as such as scammed out of money. This isn't a bitcoins-protocol issue, this is a people issue.
Note that the other exchanges are up now, very quickly after everyone stopped to check themselves.
