If you have a Nest security camera in your home, please make sure you have enabled two-step verification (2SV).
That way, even if you have made the cardinal sin of choosing a password for your Nest camera that you have previously used somewhere else on the internet, it will be much much harder for a hacker to hijack your camera and demand you subscribe to PewDiePie’s YouTube channel or put the fear of God in you that North Korea has launched a missile in your direction.
The current wave of hacks aren’t because of a software vulnerability on Nest’s internet-connected cameras, but instead because of the bug in users’ brains which means that they keep reusing the same passwords for multiple accounts and devices.
Password reuse is one of the most common mistakes made and also one of the riskiest things you can do the internet. You should have unique passwords for each account – and if you find it hard to remember them all (I can’t imagine how you *could* remember them all) you should use a decent password manager to do the job for you.
Oh, and if you’re not sure why some people are using hacking techniques to encourage people into following PewDiePie on YouTube, just listen to this recent episode of the “Smashing Security” podcast:
