PlaySpan, which provides game sales and micro-transaction payment support for virtual goods in a myriad of games including World of Tanks, Guild Wars and previously Eve Online, has been breached by hackers who apparently swiped the personal information of millions of users and disseminated it online, according to Develop.

The information stolen includes user IDs, email addresses and encrypted passwords.

The PlaySpan Marketplace site, used for micro-transactions for more than 1,000 games, currently displays a message which reads: "The PlaySpan corporate site is undergoing system maintenance. We appreciate your patience and will be back online shortly."

There doesn't appear to be any mention of the breach or security risks on the site or in the site's press center, press releases or blog.

PlaySpan told Develop that it doesn't appear that hackers made off with any credit card, debit or pre-paid card information, they are still running an investigation and forensic analysis into the breach.

The spokesperson added that the service has been shut down while they conduct a full investigation into the break in.

Reached for comment this afternoon, Eve Online developers CCP told Polygon that they don't have a current relationship with PlaySpan and that their gamers shouldn't be impacted by the breach.

"There have been some misleading articles published this afternoon regarding a breach at a company called Playspan," according to the statement sent to Polygon. "CCP has no current relationship with Playspan. The only relationship we have ever had with Playspan is that in the past is they have resold ETCs.

"We do not share login information with any other company. The only way your credentials for EVE could be at risk is if you had set up an account at Playspan in which you re-used your email/EVE login credentials such as your username or password. If you have done such a thing we suggest you change your EVE password as a precautionary measure."

Guild Wars developers ArenaNet told Polygon that they've never used the service for micro-transactions or billing, but that they did sell Guild Wars products through the company's online store.

"ArenaNet does not use and has never used PlaySpan for billing or micro-transaction services inGuild Wars or Guild Wars 2," they wrote in a prepared statement. "We do not share account credentials with PlaySpan or any other company. As with any security issue, if players use the same credentials across multiple services and accounts, then that presents a risk to their account and we encourage them to change their password.

" This incident does highlight the importance of using strong, unique passwords for every account you wish to keep secure. For more information about account security, we encourage you to read this post by Mike O'Brien."

We've reached out to Wargaming.net for comment and will update this story when they respond.

Update: PlaySpan sent us an official comment, noting that while they have more than two million customers with registered accounts, only about 117,000 of those accounts are active.
