Just received this quick response from Counter
Hi m8
We are not fully certain what the hackers managed to get into, but they did get into both the forum and ukdirt databases to delete them.
There are no payment details in these databases - the part I'm most concerned about as I have to look after this for all the members.
What they probably could see is your ukdirt and forum registered email address and password.
Hopefully you do not use the same password for the forum and ukdirt or anything else, if so, I'd change them.
With well over 5,000 members in the database, it's more likely they were targetting Admin details than general members.
I wish this would just all go away, the Admin team are likely to.
Cheers
