WoW - authenticator users come under attack.

Crooks have developed a man-in-the-middle-attack designed to circumvent authentication kit used by dedicated World of Warcraft gamers.

The ruse relies on tricking gamers into installing Trojans disguised as gaming ad-ons. Once applied the malware allows hackers to capture and relay authentication commands next time a victim logs on to Blizzard's servers.

The hackers divert and then relay authentication commands before looting gaming accounts for virtual gold, presumably for resale. Meanwhile the results of a failed login are played back to victims, effectively locking them out of their compromised accounts for at least the time needed to pull off the scam.
