The company already disabled the Sega Pass website temporarily while it investigates the incident and has reset all passwords.

The breach is the latest large-scale hacking incident to happen in recent months. Sony has had several systems compromised, most infamously its Playstation Network and Qriocity service, exposing personal and credit card information on millions of customers. Citibank also fell victim to a hack attack that compromised credit card data, as well as U.S. government agencies

The LulzSec hacker group has reportedly offered to help Sega in its investigation.
