Sony took its first public step by closing down the two networks, but it didn't disclose what it already knew: the networks had been hacked.

The company said it was still investigating the cause of the outage and that it would be "a full day or two" before everything was back to normal.
A posting on Sony Europe's PlayStation blog suggested the networks had been attacked.
