Looks like there has been some issues with World of Warcraft being hacked. Some people may have woken up today to find themselves banned or have their accounts drained. This is because the most recent edition of Adobe Flash has some flaw in it and it has been exploited. From an older post about issues they've had with Flash on the WoW forums:
A recent vulnerability has been discovered in popular web-content delivery program Adobe Flash, and it could potentially be used to target World of Warcraft players and accounts. The newest available version of Adobe Flash, version 22.214.171.124, does not contain this vulnerability, and we recommend that everyone upgrade their Flash player as soon as possible by visiting the Adobe.com download page at the link below.
In addition, to avoid exploitation of this vulnerability, we have temporarily disabled the ability to post hyperlinks in our forums. Any links will need to be copied and pasted into a browser. We’ll continue to evaluate any potential security threats and take any steps necessary to ensure a safe and fun environment.
Jonah Falcon over at Game Stooge, had his account hacked and it wasn't even activated. This means it was not phished, but happened on Blizzard's side. Lucky for him he didn't use his credit card for his account, but be careful if you do and make sure you update your Flash player.
