The city of St. Paul has become the latest target of a cyber attack targeting essential systems and digital services.

St. Paul Mayor Melvin Carter says the city suffered a digital security breach by a targeted attacker starting last Friday. Wireless internet in city buildings is down, and it's not known how much data has been compromised.

We're learning Minnesota is uniquely prepared to investigate cyber attacks, like the one that hit St. Paul. Minnesota is just one of four states with a National Guard team dedicated to cyber protection.
