Many smart TVs were sold on Black Friday and Cyber Monday and the FBI is issuing a warning for people to beware of hackers.

Pat Adams, of Woodbury, says his son, a digital marketer, once hacked into his computer to show him what could happen.

"He was able to look at me and tell me what I was doing, and I didn't even know it," Adams said.

Matt Pascucci, a cybersecurity expert, says that anything with an internet connection can be hacked into and that hackers could use the information as ransom.

The FBI's Oregon office released a list of smart TV security recommendations, including learning exactly what features TVs have and how to control them, not depending on default security settings and changing passwords if possible. It also suggests checking the privacy policy for the manufacturer and streaming services you use and confirming what data they collect, how they store it and what they do with it.

The FBI points out that hackers can also do things like change channels on your TV and play with the volume.
