Unprotected Windows users visiting these sites can get infected through malicious browser pop-ups. The malware also spreads through infectious emails, game forums, in-game chat, and other mediums. The culprit of the latest attack is a variant of PE-Looked (a strain that normally targets the popular online game Lineage), a representative from Trend Micro told The Sydney Morning Herald.

The latest attack sparked a warning from Eilanai, a moderator on the World of Warcraft forum explaining how gamers might protect themselves from key logging scammers.

Many WoW gamers have been hit by the scam and a good number are having difficulty getting access to their account, even after following the instructions of Blizzard Entertainment, the game's developer. "As there are many players affected by this issue, it may take some time for our Account Administration team to reach your issue and verify your ownership, so please be patient while waiting for a response," Eilanai wrote in response to an earlier forum thread on the issue.
