The AntiSec hackers have released a massive amount of confidential information they got after breaking into Web sites of more than 70 US police agencies, claiming that the compromised data will "embarrass, discredit and incriminate police officers across the US,".

The daring war on US police was launched by hackers the AntiSec and LulzSec groups in retaliation for the recent arrest of key activists of the underground anti-security movement, especially that of teenage hacker Jake Davis who had acted as a spokesperson for the hacking gang.

In one of the biggest "data dumps" in recent times, 10GB of data compromised. The data was posted on file share platforms, and it contained 300 email accounts from as many as 56 law enforcement Web sites, user names and passwords, home addresses, phone numbers, and Social Security numbers.

The hackers named the huge data cache as "Shooting Sheriffs Saturday."

The hackers teased and taunted Sheriffs, exposed police informers and said they had no qualms about putting informers' lives in danger. They also used stolen credit card information to make online donations to Bradley Manning and organizations like ACLU and Electronic Frontier Foundation.

They exhorted comrades to step up attacks on government agencies and corporate bigwigs. "To our hacker comrades: now is the time to unite and fight back against our common oppressors. Escalate attacks against government, corporate, law enforcement and military targets: destroy their systems and leak their private data.”

The hackers said they have no remorse, no sympathies. "We have no sympathy for any of the officers or informants who may be endangered by the release of their personal information."

"For too long they have been using and abusing our personal information, spying on us, arresting us, beating us, and thinking that they can get away with oppressing us in secrecy… Well it's retribution time: we want them to experience just a taste of the kind of misery and suffering they inflict upon us on an everyday basis."

The anti-security zealot group hack had hacked into the server of a company called Brooks-Jeffrey Marketing, a media services hosting company. Law enforcement agencies in Arkansas, Kansas, Louisiana, Missouri and Mississippi were affected by the operations.

In June, hacking group Lulz Security had broken into the Arizona Department of Public Safety’s computers and stole a cache of files labeled as training manuals, emails and intelligence documents.
