How about the final damages from the attacks?
I have waited for next adjustments or improvements (serious ones) of Goldcoin team in order to prevent future potentially attacks.
It is believed that the attacker used the Bitcoin DoS vulnerability to exploit several of Cryptopia's daemons.
The GoldCoin client was patched in September with ACPD which is Advanced Checkpointing with Difficulty Detection. Our developers also patched the Bitcoin DoS vulnerability. We have informed Cryptopia that the network is safe but they have not responded to our last three emails.

Again, all of this occurred several months ago. This is old news.
