Hacker group Lulz Security has published documents stolen from Arizona police in protest at the state's controversial new immigration law.
The action appears to be part of the anti-government campaign Lulz Security (LulzSec) announced with associated "hacktivist" group Anonymous, which has claimed attacks on websites run by the US Senate and CIA, and the UK's Serious Organised Crime Agency (Soca).
Lulzsec has also been associated with intrusions at Sony and US public broadcaster PBS ahead of its anti-government campaign, dubbed AntiSec by the group.
Lulzsec says it targeted e-mails and intelligence documents at the Arizona Department of Public Safety in protest at controversial immigration legislation – known as Arizona SB 1070 – and the "racial profiling anti-immigrant police state that is Arizona," according to US reports.
Other recent targets of the Lulzsec group include the Atlanta chapter of FBI affiliate InfraGard.
It is interesting that both Sony and InfraGard were hacked and lost their personal information using the same well-known vulnerability, says Alan Paller, director of research at the SANS Institute.
Despite the fact that the SQL-injection vulnerability is well known, neither victim was able to protect its website, he says.
But what makes the story even more interesting to a wider audience is that the InfraGard group was running a website hosted on a web hosting service, says Alan Paller.
"That's just what tens of thousands of other small and medium sized organisations all do. All of them are easy prey for hackers," Paller said.
The director of the US Department of Homeland Security's National Cyber Security Division is expected to announce the major first step to protecting all those potential victims early next week, says Paller.
