Good news! We've regained access to the domain and they are pointed at our old nameservers again. I still must stress that you cannot trust emails from @primedice for the next day or until we say so.
We're in the process of transferring the domain to a more secure registrar. I will let you know when the site is back and it is safe to play, but hopefully within the next day.
You should make a mandatory password change for everyone who logs back into primedice
Not only that but a way to make sure those who did attempt login on the phishing site could securely login their own account.
Luckily I'm not one of those.
This could be a tricky one as people who are already fallen victim here have a chance that the hacker will be the one changing there passwords. Emails are also affected as some will have the same password as there Primedice accounts. I think a signed message from there last withdrawal address might be a better alternative, although it will take up more time as the process will be done one by one.
