I doubt anything will happen
The FBI will probably not catch anyone.
they have levels assigned to hacking, this is probably a very low priority. mostly because stolen ssn's and names are not a high priority, stolen identities are not really all that bad for the economy, if your identity is stolen you have to pay the government alot of money to prove that your the person you say you are.
as well the banks which are the backbone of the Government and all those associated with the government make alot of money anytime your identity is stolen because you have to pay them as well to prove who you are, and usually a large fee is included when you get identity theft protection.
for those of you who believe that our government and those affiliated with it, such as the fbi are looking out for you, you are sadly mistaken.
the individuals are probably all very good people who care deeply for the people they have sworn to protect, but the people above them are the ones who make the decisions.
so like some have said, most likely nothing will be done, its all political from here.
i also agree that investing the resources in a traceback of spoofed and proxied IP's is a large investment that they are probably not likely to make.
hackers only get caught when its easy to catch them, or when its politically expedient to catch them. otherwise good luck. i've been a sysadmin for an isp for a while now and i've had companies call me because they have been hacked, and couldnt get any real help from the authorities because it would cost too many man hours to justify the return they could get from jailing the criminals.
justice without profit is a pointless enterprise here in america.
