Sony was targeted by Anonymous after it filed a lawsuit against George Hotz, a 21-year-old hacker who unlocked the PlayStation 3's operating system. In Sony’s original blog post about Friday’s outage, the company mentioned that an “outside party” might be responsible. That post has since been changed.
A recent post on Anonymous's Facebook Page seems to take credit for the outage.
"Take a break from online gaming for a while.....it will help your skills, your health, and your emotional levels, which by the way are a bit out of order if they are being shackled by the PSN being down," it says. "We have no qualms about our actions, even though it may affect fellow anonymous or supporters... we hope they understand the bigger picture."
However, the organization denies involvement on its website, posting an announcement with the headline, "For Once We Didn't Do It."
"While it could be the case that other Anons have acted by themselves, AnonOps was not related to this incident," it says.
