( CNN ) -- Sony 's PlayStation Network , the gaming and entertainment platform knocked offline for weeks this spring , has been hit again . In a message to members , Phillip Reitenger , Sony 's chief information security officer , said the company detected an attempt to try a massive number of user IDs and passwords on its network . The PlayStation Network and Sony Online Entertainment were impacted , Reitenger said . But unlike the spring attack , when virtually every one of the PlayStation Network 's 70 million subscribers lost total access , only one-tenth of 1 percent ( about 93,000 people divided between PSN and Online Entertainment ) had their information accessed and were locked down , the company said . Only a small percentage of those accounts showed suspicious activity after they were accessed , he said . `` 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 , '' Reitenger wrote . `` We encourage you to choose unique , hard-to-guess passwords and always look for unusual activity in your account . '' No credit card information was accessed in the hack , according to the letter . Network customers who were affected received an e-mail from Sony notifying them of the issue . Everyone who is affected is required by Sony to change their passwords on the network . The PlayStation Network went down on April 20 after a Web attack on the network , which lets people download games and videos and play them with each other online . Most players could n't use the network for weeks and it was n't completely restored until the PlayStation Store went back online in early June . A London 19-year-old allegedly affiliated with the hacker group LulzSec was arrested in late June in connection with the Sony attack . LulzSec , purportedly a spin-off of the bigger hacker collective Anonymous , posted what they claim is proprietary information from Sony Pictures and other Sony properties ' websites online . At June 's E3 video-gaming expo , Sony Computer Entertainment of America president Jack Tretton apologized to players for the outages . He called it the `` elephant in the room '' and thanked gamers for staying loyal during the down time . `` You are the lifeblood of this company . Without you there is no Playstation , '' Tretton said . `` I want to apologize , both personally and on behalf of the company , for any anxiety we caused you . Many users had responded angrily in the spring , with many of their complaints centering around the week Sony took between the hack and making it known to players . This time , comments on Reitenger 's online post seemed more positive . `` Thanks for letting everyone know so soon , '' one user wrote . `` It 's better to be aware . '' `` This is good that your letting us know this before everyone goes in another rage , '' said another .
Sony PlayStation Network hacked -- again . Sony : " We are aware of the issue and have taken steps to address it. No credit cards were accessed , company says . Users seem happier with response than they were with delays in announcing last attack .
