The Japanese video game firm Sega, which was the latest victim of a network breach, said on Sunday that about information on 1.3 million customers has been stolen from its database via a website of its European unit.

Names, birth dates, e-mail addresses and encrypted passwords of users of Sega Pass online network members has been compromised, Sega said in a statement.

However, payment information was not compromised as Sega uses external payment providers. Sega customers have been advised to change passwords and be alert if they received emails requesting such information.

The hacking of Sega is the latest in recent times notwithstanding the fact that hacking had earlier skewered the likes of entertainment giant Sony, defense contractor Lockheed Martin, the U.S. Senate, and the FBI, cnetwebsite reported.

The hacker group Lulz Security (or LulzSec), which has carried on relentless attacks on Sony, PBS,, the US Senate, the CIA, and a slew of gaming sites including EVE Online, Minecraft and League of Legends, has denied involvement in the Sega case.

Interestingly, the group showed sympathy for the company on its Twitter feed.

LulzSec sent out a public tweet addressed to Sega: @Sega - contact us. We want to help you destroy the hackers that attacked you. We love the Dreamcast, these people are going down, the tweet read.

“We are deeply sorry for causing trouble to our customers. We want to work on strengthening security, Yoko Nagasawa, a Sega spokeswoman told Reuters.

The Pass network went offline on Thursday, the day when Sega learnt of the breach and it is not known when it will go online. The company said it is investigating the breach and the network was going through some improvements.
