My wife has an iphone and downloded the little app to get an online authenticator. We also purchased authenticators for both of our accounts. It seems like a pain when you are getting used to it, but after this weekend I think it was a great investment.
We had two guildies get hacked this weekend. In fact, it seems like our server was hit pretty hard this weekend with attacks. My guess is that the hackers probably had to deliver some gold that as bought.
I had google adds on this page, but it was pointed out to me that the ads sometimes lead to gold sellers pages, so I decided to remove the completely. I want no part on helping those people make a buck out of the game they exploit.
Check your virus software, change your password, and please, please get an authenticator. If you have an android or an iphone or touch its pretty much free… also ordering it is not too expensive. It will make you a lot safer… it sucks to log in and have no gear anymore, or in some cases, not even characters to play with anymore.
