Hackers can get into your refrigerator, too

It's a hackers' world.

They're tapping into every device you can think of and some that you can't think of, like … your refrigerator. That's right, the 'fridge.

According to a report this week by security firm Proofpoint, hackers are attacking "smart" appliances in your household.

The firm looked into attacks that occurred between Dec. 23 and Jan. 6, and found that more than 25 percent of spam email was sent by home-networking routers, connected multimedia centers, televisions and at least one refrigerator.

Just like personal computers can be compromised, so can your "smart" appliances. As we are slowly entering a "smart world," where everything is connected to the Internet and you can check your email everywhere, more things are becoming targets for hackers who are hungry for people's data. And we are not be prepared or may not even be aware of these hacks, the report states.

"Many of these devices are poorly protected at best and consumers have virtually no way to detect or fix infections when they do occur," Proofpoint's Information Security General Manager, David Knight, said in the report. "Enterprises may find distributed attacks increasing as more and more of these devices come on-line and attackers find additional ways to exploit them."

And while not many cases have been reported, it's something consumers and manufactures should keep in mind.
