The Arizona Republic says nearly 300 documents were downloaded Tuesday from the website and uploaded online.
Most of the documents already were widely available on the site for the public’s use. But Arizona Legislative Council officials say the security breach is concerning.
Azleg.gov provides the public with information about the progress of House and Senate bills, contact information for legislators, and calendar information for events at the Capitol.
Officials are continuing to investigate the extent of the breach.
A hacker group called Malicious Security tweeted about the breach in the state Legislature’s website Tuesday afternoon and took credit for it.
