Hacking group LulzSec has denied responsibility for the network attack on Sega's online gaming network Sega Pass. Instead, LulzSec issued a statement to Sega saying that they will help Sega to take down the hackers who attacked the site.

@Sega - contact us. We want to help you destroy the hackers that attacked you. We love the Dreamcast, these people are going down, the hacking group posted on its Twitter feed.

No hacker group has claimed responsibility for the attack so far. Although, a number of recent attacks on game companies and their online services are credited with LulzSec, its denial of the credit has brought in a twist of events.

Sega's online gaming network Sega Pass was hacked earlier on Thursday, which made the service completely down.

Sega, in an email reportedly sent to the members of the system said, As you may be aware, the SEGA Pass system has been offline since yesterday, Thursday 16 June, the email begins. Over the last 24 hours we have identified that unauthorized entry was gained to our SEGA Pass database.

We have identified that a subset of SEGA Pass members' emails addresses, dates of birth and encrypted passwords were obtained, Sega added. To stress, none of the passwords obtained were stored in plain text.

Sega Pass users have been recommended by the company officials to change their login credentials as soon as possible.
