Be smart. Be safe. Get all NAUT off MintPal now. And everything else. Not worth the risk.
I'm moved some off.. but I think it's an overreaction to take everything off. There's many fear pedlars in the forums and twitter who have a blatant anti-mintpal agenda. The twitter crypto crew who attempt to behave like helpful traders are really a bunch of loosely coordinated scammers.
All you need to do is read MintPals own release:
https://support.mintpal.com/index.php?module=announce&sec=view&id=18"How did the attack happen?
The malicious user was able to inject a withdrawal request directly into our database bypassing the risk control measures that we have in place. We have found no evidence that our server infrastructure was directly accessed in the attack."
"What about COLD storage?
This is perhaps the most important question we have been asked. We did have COLD storage setup for VRC, however in this instance, due to an error for which only we can be accountable, we had transferred far fewer coins than was required, resulting in a large proportion of coins being left in the HOT wallet."
Per their statement this was a Mintpal issue. Further they failed to properly use cold storage. Basic common sense: You should not be trusting them right now for any coin. If you have been around crypto for any length of time you should know that about exchanges by now.
Be safe, remove all coins. It's not worth the risk. They have not earned trust. No exchange has.
