Remember when people were scared of the PlayStation 3 being used for nefarious purposes? You know, with it's uber powerful cell processor and all? It turns out they were right! A group of hackers used a farm of 200 PS3s to crack SSL (secure sockets layer) certificates. According to ZDNet's Zero Day blog:
The hackers recently presented their research at the 25C3 conference. This is pretty crazy stuff. People have already been using their PS3s as powerful distributed computing device (Folding@home), but this takes it to another level. Hopefully Dr. Evil never gets his hands on a PlayStation 3 cluster.
TO GOD BE THE GLORY
