(CNN) -- A second hacking attack has yielded personal information belonging to nearly a dozen of its employees, the Arizona Department of Public Safety said Wednesday.
The cyberterrorist group "antisec" gained access to the personal e-mail accounts of at least 11 employees but did not breach its servers, the department said in a statement.
"We would like to make it clear that these intrusions have in no way affected public safety, or the ability of the agency to conduct its mission," state police said, adding a criminal investigation has been launched.
According to a posting on a public website, "antisec" said it had gotten online dating account information, "seductive girlfriend pictures," chat logs, phone numbers and other personal data and information.
Late last week, another hacker group, LulzSec, released sensitive information about officers. It said it posted the information in response to Arizona's immigration law.
"We are releasing hundreds of private intelligence bulletins, training manuals, personal email correspondence, names, phone numbers, addresses and passwords belonging to Arizona law enforcement," LulzSec said in a statement. "We are targeting AZDPS (Arizona Department of Public Safety) specifically because we are against SB 1070 and the racial profiling anti-immigrant police state that is Arizona."
LulzSec had pledged to release more "embarrassing personal details" of military and law enforcement each week.
It was not clear Wednesday whether LulzSec and "antisec" were affiliated or shared the same data.
LulzSec said Saturday on its website that it was disbanding.
LulzSec claimed recently to have attacked the CIA website and took credit for hacking into the website of American public broadcaster PBS and posting a fake story saying the rapper Tupac Shakur was still alive. He was killed nearly 15 years ago.
The Arizona Highway Patrol Association last week said the release of documents is unsafe for officers.
"Law enforcement officials go to many lengths to protect their identities," said Jimmy Chavez, president of the organization. "These individuals maliciously released confidential information knowing the safety of DPS employees, and their families, would be compromised."
The immigration bill, Arizona Senate Bill 1070, passed last year but was quickly challenged in court by the Justice Department. The measure would have required local police, while enforcing other laws, to question the immigration status of anyone they suspected of being undocumented.
The U.S. Court of Appeals for the 9th Circuit placed an injunction on parts of the measure in April saying that those parts overstepped Arizona's authority.
