In the digital age, the fear of getting hacked is high up on the list of worries. There are sophisticated methods of bypassing security, as well as simple methods using a compromised email and passwords.

That’s exactly what happened to a family with their Nest home security camera, according to a report from The Mercury News. On a slow Sunday afternoon, the Lyons family heard a loud noise emit from their Nest camera, followed by a warning that three North Korean ballistic missiles were heading to the US.

After “five minutes of sheer terror,” the family finally figured it wasn’t real and another 30 minutes to figure out what  happened. But the damage was done and the Lyons family was truly left on edge.

Turns out, the hackers didn’t use crazy high tech methods, but used the family’s email and password to hack into the account to deliver the hoax through the Nest camera speaker. This highlights the importance of not duplicating passwords on different accounts.

You’ve probably already heard this modern age platitude before but that doesn’t make it any less true. It’s the domino effect: If a hacker gets the password to one account and you repeat passwords for a different service, then they’ve essentially hacked into all of your accounts.

The least you can do is avoid repeating passwords. There are other options like two-factor authentication, which Nest offers with SMS tokens. However, that’s only optional, not set as default, so users will have to activate the feature on their own.

As privacy and data protection continues to grow in importance, keep in mind how you formulate your passwords. It could be the difference between keeping your accounts safe or being taken advantage of by rouge hackers.
