The latest attack by AntiSec hackers was targeted at the police. The hackers associated with hacker groups LulzSec and Anonymous leaked over 10GB of information from over 70 law enforcement agencies in the U.S. on Friday.

"Sabu," the supposed leaker of the hacker group Anonymous, dubbed the data dump as "Shooting Sheriffs Saturday Release" in order to "embarrass, discredit and incriminate police officers across the U.S."

The leaked data contain hundreds of emails, personal information about officers, police training videos, the contents of insecure anonymous tip systems, and over 300 mail accounts across 56 law enforcement domains, says The Hacker News.

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.

The hackers also 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."

One of the biggest "data dumps" in recent times was staged by the hacker group in retaliation against the recent arrest of key activists of the underground anti-security movement.

Last week, Jake Davis, a 19 year-old hacker known as "Topiary," allegedly a core member of the hacking group LulzSec, was arrested and was granted bail in a London court.  Davis was charged with hacking into websites, including that of Britain's SOCA, which was out of service for several hours on June 20 after apparently being targeted, according to AFP.

"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," the group said in an online post. "We stand in support of all those who struggle against the injustices of the state and capitalism using whatever tactics are most effective, even if that means breaking their laws in order to expose their corruption. You may bust a few of us, but we greatly outnumber you, and you can never stop us from continuing to destroy your systems and leak your data."
