I am in Gnomerigan and recieved a whisper from [Blizzcards] with an address to goto to claim a prize. It requires my login information. Is this authentic, or a security problem that I should report?

Q u o t e:
Right click - report spam. If a GM whispers you, they will have a blue Blizz logo next to their name, and the chat shows up in a separate window.

Yes, Vetch, that was a phishing whisper. If you would like more information on what it will look like when a Game Master contacts you, please visit:

I received an in-game whisper from someone claiming to be a GM. How do I know if it's a scam?
