Tribune Media's ProSportsDaily notified the California Attorney General's Office Wednesday of a data breach that compromised user information.

On April 4, an attacker hacked into the ProSportsDaily Forum website and compromised user login credentials for the site and possibly other information that is available through accessing such accounts, according to an April 8 Notice of Data Breach.  

The notice didn't mention that financial information was compromised however; it did recommend that users remain vigilant by reviewing account statements and credit reports for any unauthorized activity.

Officials immediately took the website offline to assess the impact and have since isolate and patched a software vulnerability in response to the breach, the notice said.

All users were instructed to change their passwords on the forum and on any other sites where they may have used the same login credentials.
