Sony has been the victim of another attack on the PlayStation Network and Sony Online services, where intruders attempted to log in using a large number of account names and passwords. The vast majority of these login attempts failed, according to Sony, leading the company to believe it has been a victim of an attack of opportunity where hackers tried to access PSN and SOE accounts using information taken from other sources.

"These attempts appear to include a large amount of data obtained from one or more compromised lists from other companies, sites or other sources," Philip Reitinger, the SVP & Chief Information Security Officer of the Sony group wrote on the official blog. "In this case, given that the data tested against our network consisted of sign-in ID-password pairs, and that the overwhelming majority of the pairs resulted in failed matching attempts, it is likely the data came from another source and not from our Networks."

93,000 accounts have been accessed due to this attack, but Sony claims little activity was seen on the compromised accounts before they were locked down. If your account was affected, Sony will be e-mailing you with details and to have your password reset. The company claims credit card information is not at risk.

The best course of action is to make sure you don't share account names or passwords between online services. "We want to take this opportunity to remind our consumers about the increasingly common threat of fraudulent activity online, as well as the importance of having a strong password and having a username/password combination that is not associated with other online services or sites," Reitinger wrote. "We encourage you to choose unique, hard-to-guess passwords and always look for unusual activity in your account."
