Ars Technica has an unconfirmed report that ArenaNet has been experiencing attempts at unauthorized access to Guild Wars 2 accounts. These differ from the typical such attacks as they are reportedly the result of a breach at an unnamed Guild Wars fan-site, and that the perpetrators are now trying the username and password combinations from the site to take advantage of users who also use them for their game account. They include the obvious warning that this is not a good idea.
