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.

The Minnesota National Guard’s Cyber Protection Unit is working to help St. Paul respond to a cyberattack that began last week. This is the first time the eight-year-old unit has deployed to an attack on Minnesota computer systems.
