I'm not sure I think the word 'attack' is right here. Crypto by design says that if anyone controls over half the network, they get to say what happens. Sounds like democracy, specifically the 'tyranny of the majority': over half the network votes that they get more of your money, so they do!
Of course if you're in the other 49% you might feel attacked, but ultimately this is working as intended.
The intent is a currency which can be reliably used for exchange of goods and services. This would seem to cause a failure of the basic reason for its existence.
The intent of democracy was a sensible way of running countries but it seems to show similar failures. This is leading presently to quite a lot of odd debate in the UK on how having another democratic vote would be a betrayal of democracy and similar.
Of course if you're in the other 49% you might feel attacked, but ultimately this is working as intended.
