Hacktivist groups Anonymous and LulzSec have retaliated after the arrest of several suspected members and supporters by hacking the web sites of around 70 US law enforcement agencies and posting over 10GB of private details online.
Under the groups' AntiSec banner, the hackers leaked data including hundreds of private email spools, passwords, credit card details, addresses and social security numbers, according to a statement posted to Pastebin.
Anonymous and LulzSec said that the hack had been carried out in solidarity with 'Topiary', who it is claimed was recently arrested in the UK, as well as those supporters who were arrested for participating in a distributed denial-of-service attack on PayPal.
"We have no sympathy for any of the officers or informants who may be endangered by the release of their personal information," the statement read.
"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."
The initial hack was first carried out a week ago and targeted marketing and hosting firm Brooks-Jeffrey Marketing. According to the hackers, it took less than 24 hours "to root BJM's server and copy all their data to our private servers".
Reports have suggested that some of the posted data relates to ongoing investigations.
Also at the weekend, Anonymous continued its campaign against perceived abuse of power by state actors by defacing the web site of the Syrian Ministry of Defence.
The group pledged its support for the Syrian people in a message posted to the site, and encouraged the military to "rise up against the regime" following renewed violence by government forces against protesters in Syria.
