Update: If you have been hacked here is Blizz link to use to get problem resolved http://us.battle.net/support/en/article/compromised-diablo-iii-account
According to Blizzard, any time they release a new game, like Diablo 3, or when they release an expansion, there is an increase in the number of accounts reported being Hacked.
There are lots of reasons for this, but here some basic things you can do to help prevent this, these are things you should be doing to reduce your risk from these types of problem in general (ie internet banking, internet buying, etc).
First make sure your Operating System (OS) is up to date (as security problems are found, they are fixed, you need these to help keep hackers out, it is like getting a broken lock on your house door fixed), if your not sure see these links:
Second if your not using an AntiVirus/AntiMalware program already get one and use it!
Cliff recommends these two free AntiMalware products:
I can't recommend any other free ones at this time, I have been using
Security Essentials for some time now since having serious problems with a different free product.
I haven't yet used the Sophos product, because I don't have a Mac yet, but I will be getting a Mac in a few weeks, and
Sophos' AntiMalware is what my research leads me to use, I will report directly about that product in a future post.
Those two steps will do a lot to prevent a keylogger or something else bad from getting on your computer.
Third update your Browser,
Blizzard has good guide to this
Next you should pick a
strong password, and if you really want to do something
extra get an
Authenticator or a
Mobile Authenticator from Blizzard, you can use these for Starcraft 2 & WoW as well.
What that does it lets Blizzard send you a 2nd temporary password to use in addition to the password you picked, it is like needing two keys to open a vault or launch a nuke.
I have at least one friend that has using this for some time, and it saved his account from getting hacked when all his local gaming buddies accounts got hacked.
VOD below from Blizzard describes these products and how to use them.
Cliff recommends the Authenticator over the Moble Authenticator, because most of us will connect our phones to our computers at least some of the time, and if there is MalWare on the computer, it could infect the phone as well.
Friend of mine recently had that happen to his phone, his infected computer also infected his phone.
Or if you have MalWare on your phone, from App or something else, the Hackers might be able to access that 2nd password.
I
REALLY recommend the Authenticator if you use a shared or public computer!!!!!!!
Hope that helps.
Stay Safe,
Cliff
