Cyberattacks and the critical services we rely on

Hackers disrupted technology controls at water towers and treatment plants in more than 30 Minnesota communities last week. And the FBI says water and wastewater companies in at least six other states have reported incidents. MPR News guest host Catharine Richert talks with her guests about what we can do to protect the water systems, power grids and other public services we rely on.
