The group, known as the NullCrew, has taken responsibility for a number of attacks in recent weeks, including hacks targeting Cambridge University and government sites in Cambodia. The crew announced the hack on Twitter and Pastebin, where it taunted Sony and posted a list of usernames, email addresses, passwords and other information that appears to be related to Sonymobile.com.
Sony did not respond to a request for comment.
"Sony, we are dearly dissapointed [sic] in your security," the group says in a statement on Pastebin. "This is just one of eight sony servers that we hve [sic] control of. Maybe, just maybe considering IP addresses are avaliable [sic]. Maybe, just maybe it's the fact that not even your customers can trust you. Or maybe, just maybe the fact that you can not [sic] do anything correct technologically."
Sony has been a repeated target for hackers. Last week, a reputed member of the LulzSec hacking group was arrested for attacking Sony Pictures Entertainment last year. Raynaldo Rivera of Tempe, Ariz., was indicted by a federal grand jury in Los Angeles on charges of conspiracy and unauthorized impairment of a protected computer.
According to the indictment, Rivera and his co-conspirators exploited a SQL injection vulnerability in the Sony Website to obtain confidential information. After successfully launching the attack, LulzSec members posted the data on their Website and announced the attack on the group's Twitter account.
According to authorities, Sony's computer systems were compromised from roughly May 27, 2011, to June 2, 2011.
If convicted, Rivera faces as much as 15 years in prison.
