Not heard this news yet but I remember not so long ago when PSN network was down they claimed it was them however another person called FamedGod on Twitter called all of them out to say it was all his work and he uploaded pictures of him on the PSN Administrator account.

However whether they DDoS it or not or whatever the outcome might be we'll all have to wait for the outcome.
