Sega Corp.'s database has been hacked. The multinational video game developing company headquartered in Tokyo, Japan has sent an email to users to notify Sega Pass system users that their emails, dates of birth and their passwords were compromised by hackers. The stolen passwords were encrypted.

The email contained a message stating there is no risk financially since payment information was not stolen and the company is investigating the extent of the hacking. So far, 1.3 million customers' information has been comprised.

Sega has recommended users to change their passwords if they use the same password for Sega Pass website and other sites.

The Sega pass website is currently down and all the passwords have been reset.

When users visit the website customers will see this notice Hi, SEGA Pass is going through some improvements so is currently unavailable for new members to join or existing members to modify their details including resetting passwords. We hope to be back up and running very soon. Thank you for your patience.

The hack is the latest large scale hacking occurrence in the last several months. Sony reportedly lost around $170 million when its PlayStation Network was hacked. Citibank was also hacking victim recently, losing customer credit card information.

The hacker group LulzSec, which has been associated with a number of recent attacks on big companies, including one against Nintendo, has denied involvement in the Sega case.

The group expressed its intention to help Sega to find the attackers saying on their Twitter feed: @Sega - contact us. We want to help you destroy the hackers that attacked you. We love the Dreamcast; these people are going down.
