Partial quote from article..

On Thursday, the FBI arrested two suspected hackers who allegedly 
participated in Anonymous and LulzSec attacks. One of them, Cody
Kretsinger, faces 15 years in prison for allegedly helping break
into the Sony Pictures website with an SQL injection and
publishing user data. As we described on Thursday, the indictment
against Kretsinger says he used what's called a proxy server to
hide his identity while carrying out the attack. But on Friday it
emerged that the site he allegedly used to disguise his identity
cooperated with police working to track him down. That's got some
in the online privacy community very nervous.

The federal indictment against Kretsinger charges that he used a
proxy server site called Hidemyass.com to disguise his Internet
protocol address. By transmitting data through the proxy, a
hacker can hide his or her ISP from the target. But since the
proxy server gets between the machines on either end of that
exchange, it is in a position to know details about the hacker.
