PS3 BEING HACKED

not really no.

this greatly depends on what exactly it is you think 'hacking' is.

according the data protection act, hacking is defined as accessing information without the owner's knowledge. 

the most common way for someone to hack into a computer is to gain access to it's network.

most people use WEP and WPA-PSK keys on wireless networks.  Both are easily hacked into.

luckily not that many people would bother doing such a thing.

another common form of hacking is that people don't secure thier username and password.  with that information, they 'hack' into their account, often with criminal intent.
