What happened

The web server of the Ohio Auditor's office was attacked by overseas cybercriminals and potentially foreign state actors, and the server was temporarily taken down as a result.

Why it is dangerous: Public-facing state government systems can be disrupted or become a route to sensitive information, so residents who use Ohio state services could see outages or delays. The state reports no reason to believe personal financial information is at risk.
