As most of you have realized, there is a big increase in the number of hacks happening lately. I'm one of the victims here.
Yeah I know its user's fault most of the time to not to detect that virus (keylogger most of the time) etc. But I'm not a newbie about computers or its security, and it was the first time I was really shocked about my computer and account's security.. (I'm hacked for 2 times in 5 days, after first hack I did lots of scans and found 1 keylogger, and thought i found the problem, which is proven that i was wrong). Now I format my computer, really sure that I'm safe, and waiting for my password from Blizzard.
My point is, we all know that these hacks are occuring for gold. and I don't think there is a way to stop ppl buying golds. And most of the hacks are happening the way that hacker gets your account name and password, changes it immediately, and merges account with battle.net (last trend), etc.
And my possible solution is, in order to merge account with battle.net, and/or change password of the account, the account owner should be asked for his CD-key. Thats the easiest solution, you may be asked for credit card digits, or other stuff too. Moreover, you can send you ID or passport image to Blizzard in order to change your security settings too.
Well, there can be more and more solutions, even better than those. Is it too hard to make things work in such ways?
