Hawaii's Honolulu Police Department (HPD) has acknowledged that one of its databases was recently hacked, exposing the names, e-mail addresses and telephone numbers of more than 3,500 members of the public, along with the names, phone numbers, e-mail addresses and clear text passwords about more than two dozen HPD personnel (h/t Help Net Security).

The Honolulu Police Department told Hawaii News Now in a statement, "The Honolulu Police Department announced today that its 'HPD Alerts' database was accessed by an unauthorized person or persons this weekend, and subscribers' names, phone numbers, and email addresses were compromised. HPD Alerts was a pilot program to provide breaking information to the public. It was recently discontinued due to technical problems not associated with the cyberattack. The HPD has since removed the database and implemented additional measures to protect the information. At no time did the breach affect police services."

Hacker X-Blackerz Inc has claimed responsibility for the breach, telling HackRead that the attack was part of #OpUSA, a series of protests against the U.S. government.
