Monday night, a handful of nearly identical e-mails arrived, these ones seeking World of Warcraft account log-in information. The e-mails appeared to come from account@worldofwarcraft.com, and featured the same formatting and phising tactics of the second Valve e-mail. Again, the spam carried the Equal Housing Lender logo.

According to the security center on publisher Blizzard\'s official World of Warcraft Web site, phishing is one of the biggest sources of user security problems the company encounters. Downloading Trojans and other harmful programs disguised as add-ons or hacks for the game is another.

"People should be suspicious of anything that doesn’t come from a Blizzard.com email address, or attempts to forward you to a site that isn’t Blizzard.com or worldofwarcraft.com," a Blizzard representative told GameSpot. "If you’re unsure about any communication you receive, you can forward any email to our official address--billing@blizzard.com--and do NOT reply at all unless our Billing staff actually confirms for you that the message is legitimate."

As for what the company is doing to crack down on these scams, the rep said, "Blizzard works actively to combat fraud against our customers," and regularly updates players on new security measures through its forums and phone support.
