AntiSec-tied hackers have leaked over 10GB of sensitive data, which they called "largest cache yet," from 70 law enforcement agencies in the U.S. last night.

"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 attack was made in response to the arrest of Jake Davis,  a 19 year-old hacker known as "Topiary," who was a core member of the hacking group LulzSec.

Anonymous and LulzSec sailed out to what they call "Operation Anti-Security," a movement that encourages hackers to "open fire" (i.e. hack) any and all governments and agencies that oppose the movement, and eventually to create (force) transparent governments around the world and keep the Internet free, according to the statement made by the hackers.

On Twitter, a war of words broke out earlier this week between law enforcement and Anonymous, and the group said to be acting "in solidarity with Topiary."

"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," said the hackers.

"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."

"We have no sympathy for any of the officers or informants who may be endangered by the release of their personal information... we want them to experience just a taste of the kind of misery and suffering they inflict upon us on an everyday basis," they added.
