The hacker group "AntiSec", a collective of hackers from the infamous mother groups called Anonymous and LulzSec, has claimed that it has hacked websites of several U.S. police agencies and compromised confidential data of 10 gigabytes.

The 10 gigabytes file, AntiSec claimed responsibility for, contain numerous secret information including social security numbers, credit card details, and huge amounts of police files like emails and confidentially sent tips on crimes. The information is originated from more than 70 local police agencies, the hacker group said in an online post.

AntiSec, aka Anti-Security, said on Saturday that it has "defaced and destroyed" websites of U.S. police agencies as a revenge for the arrest of suspected peers, who are accused of hacking into the CIA, British crime agency SOCA, and Sony.

"We are releasing a massive amount of confidential information that is sure to embarrass, discredit and incriminate police officers across the US," the group said in a message, "We are doing this in solidarity with Topiary and the Anonymous PayPal LOIC defendants as well as all other political prisoners who are facing the gun of the crooked court system."

"Topiary" is the supposed name of an 18-year-old British man Jack Davis, who is accused of being a spokesman for hacking groups Lulz Security (LulzSec) and Anonymous. Davis was granted bail in a London court earlier this week.

AntiSec claimed that it had hacked servers at Brooks-Jeffrey. A Mountain Home, Ark. Company, Brooks-Jeffrey builds websites for sheriff's agencies in the southern United States.

AntiSec said that it has released the file, which contains about 100,000 emails from officers in states such as Louisiana, Mississippi, Arkansas, and Kansas. One of the emails also carries a number of information about seemingly illegal incidents from members of the public. The information includes names and addresses of the supposed offenders.

"We have no sympathy for any of the officers or informants who may be endangered by the release of their personal information," AntiSec said in a statement. The hacker group hoped that their action would reveal the crooked nature of law enforcement and damage their ability to terrorize communities.
