For the NSA that's unacceptable, because the Americans specifically don't like people to know who did it, that's even the point of some big known NSA programmes, like that thing where they hack two Cisco routers so that all the stolen data goes from A to B, but via C, and the NSA steal the data again at C, so when A figure out what's happening they blame B...

But for e.g. the Russians it's totally fine. When you send assassins as "tourists" with a patently bogus reason for travel that's not because you're too stupid to do better, it's because that's all you needed for the mission and you don't care who knows it.
