Sony recently locked down 93,000 user accounts after detecting a large number of unauthorized login attempts.

"Intruders 'using very large sets of sign-in IDs and passwords' had brief access to 60,000 accounts on the PlayStation Network and Sony Entertainment Network and another 33,000 accounts on Sony Online Entertainment's servers, Sony said," writes CNET News' Christopher MacManus.

"The attacks occurred from Friday through Monday and affected 'less than one-tenth of 1 percent' of PSN, SEN, and SOE consumers, Sony said in a statement," MacManus writes. "Hackers succeeded in verifying sign-in IDs and passwords, but Sony said credit card information was 'not at risk' during the attack."
