What is the nature of the attack and what are the risks to people currently holding Mint?
Was a 51 attack over POW part, cant go further since POS kick back in
If you are paranoid use more than 120 confirmations, this will exclude this attack since POS will always kick back in less than an hour
No double spend can be made with this attack.

>50% attack
If the attacker controls more than half of the network hashrate, the previous attack has a probability of 100% to succeed. Since the attacker can generate blocks faster than the rest of the network, he can simply persevere with his private fork until it becomes longer than the branch built by the honest network, from whatever disadvantage.
No amount of confirmations can prevent this attack; however, waiting for confirmations does increase the aggregate resource cost of performing the attack, which could make it unprofitable or delay it long enough for the circumstances to change or slower-acting synchronization methods to kick in.

Mint attack 51% of POW part was successful no POS block was generated during test attack.
Just becouse test attack wasn't created to enebled double spend that doesn't meant it is impossible.
Do you realy want attack to create panic ?
"Successfully tested on Mintcoin: no PoS blocks from 203231 up to 203441, more than 1 hour of real time."
just check blocks in explorer to see it was for real...
Mint just need fast fix that is all
