Unbelievable, how can someone hack into their binance account and not steal anything! Perhaps they are worried about not being able to withdraw without their 2FA code, so they simply pumped a coin which they were already hodling. Very smart
Hackers are smart people guys, we all know that. Strangely though, there are a lot of questions. Why did the hacker pump MANA though? How did the hacker/s know that its Bitmain's wallet?
Probably because he (they) was/were smart...
A withdraw would trigger some alarms but trades might not get attention if done slowly.
So he probably first got his hands on the account credentials bitmain used, remember that the account was compromised not binance security, he acquired a lot of shitcoins like this mana thingie and then started pumping it while selling in some other places for bitcoin or eth or any other coin.

So, good luck tracing them.
And I wonder why Bitmain choosed to fill the suit n the US, Binance has moved to Malta and they have quite a history of not disclosing info to the authorities. Maybe a move to scare them?
