Mike Hayes, CEO of Sega West, told Eurogamer last month that the firm had upped security in the wake of the PSN outage. "We did a security audit as a result...it was just a good housekeeping exercise," he said. "We made a couple of changes to our security systems. I'm sure most people have done the same...fortunately we seemed pretty solid so we didn't have to do too many additional changes." On Friday Sega admitted its Sega Pass system had been hacked, with the details of some 1.3 million users taken in the attack.
