A COMPUTER hacking group yesterday posted a new batch of personal details about Arizona law enforcement officers, marking a third attack on the state’s police and an escalation of a spree of cyber break-ins.

AntiSec, an online movement comprised of parts of the Anonymous vigilante group and the Lulz Security hacking collective, posted emails and user information as part of the attack on the US authorities. The attack has now stretched for two weeks.

The group also claimed to have defaced eight websites associated with Arizona police groups. The websites were not responding early yesterday, suggesting they had been taken offline.

As in earlier attacks, AntiSec said the new intrusions were prompted by Arizona’s controversial SB1070 immigration law. The hackers were believed to have used peer-to-peer software on one police computer to grab user names and passwords used for further access.
