Sega is the latest company to face the wrath of hackers, as 1.29 million customer details were leaked.
While no credit card information was stolen this time, unlike the 100 million user data leak experienced by Sony, many other user details were stolen, including full names, birthdays, email addresses and passwords. The taken passwords were encrypted, however.
The data were stored on the Sega Pass website, a service Sega set up to provide new product information for registered customers.
Sega has already launched a full investigation of the matter, and will provide more details regarding the hack when details emerge.
No group has yet taken responsibility for the incident, but hacking group LulzSec, in the news recently for hacking a series of high profile targets including Sony Pictures, PBS and even the official website of the US Senate, seems to have denied being responsible for this latest attack, and have even offered help to Sega to track down those responsible. "We want to help you destroy the hackers that attacked you. We love the Dreamcast, these people are going down," tweeted LulzSec.
