The Arizona Legislative Council said Wednesday they are still investigating how an anonymous group was able to enter the site and upload more than 300 documents.
Council Director Mike Braun told The Arizona Republic the group did nothing destructive. However, he says they were able to get in at a level deeper than most people get.
Officials have taken some site functions offline while the breach remains under investigation.
Braun says the hacking has not affected the Legislature’s internal network — which includes the email system, drafts of bills and other documents.
Malicious Security tweeted about the breach in the state Legislature’s website Tuesday afternoon, taking credit for it.
