Symantec has discovered a cache containing some 44 million stolen gaming accounts, including thousands from World of WarCraft and Aion.

The anti-virus developer wrote in a recent blog entry that the server contains some 17GB worth of stolen data, likely obtained from sites using programs like Infostealer.Gampass.

In order to verify whether the login data is valid, they are apparently distributing a threat known as Trojan.Loginck to multiple computers, which then begins trying to login using the stolen account data. If it's successful, it logs the time on the database along with the valid username and password combinations, then moves on.
