The Department of Homeland Security released a report that shows a 52-percent increase in cyber attacks on power and nuclear facilities last year.

Nearly 200 attacks were reported, including some successful break-ins.

Hackers gained access through the Internet and were able to crack weak passwords.

Authorities say this shows the U.S. infrastructure is vulnerable.
