Bret has Windows 10 and uses Windows Defender, but it keeps telling him he's unprotected -- even if he's just run a scan. Leo says there's a little red flag in the task menu, and if he opens that up, it will tell him what's unprotected. Bret says it's just notifications that keep coming up, and Leo says he can just turn those notifications off. Leo suggests looking at the screen that tells him what's unprotected. If he doesn't have protection updates turned on, he may want to do that. If he wants to be as safe as possible, he should turn all that stuff on.
Pwn2Own is an annual competition held at CanSacWest in Canada. Prizes are awarded to the hackers who can most quickly hack various operating systems and programs.

A recent study has found that the greatest threat to our critical infrastructure is squirrels. Not hackers, not enemy states, not organizations, but squirrels. Small animals have been responsible for more than 1,700 power cuts affecting 5 million people.
Many publications including The Guardian reported that the messaging app WhatsApp was insecure and hackable. The creator of that encryption protocol, Moxie Marlinspike from Open Whisper Systems, posted on his blog that this was incorrect. Now a large number of security professionals have written an open letter to The Guardian asking them to retract the story. There is no back door in WhatsApp, and the article was wrong.

Here's some suggestions from the chatroom:
Artie is getting his son a Chromebook for Christmas. How can he keep it safe from computer viruses? Leo says that Chromebooks are relatively virus free, so he won't have to worry about that. To keep his kids safe online, Leo advises OpenDNS and their parental filters.
Jonathan has a Windows laptop and he wants to add a fingerprint scanner. The one he's looking at works with WIndows Hello, but there's no real branding. Leo says that chances are, one Chinese company makes it and then sells it to multiple companies who put their name on it. The good news is that it works with Windows Hello. Jonathan should check out the Eikon fingerprint scanner. It's the one he recommends, and it's only $20.

These Denial of Service attacks rely on 'bot nets' that are actually made up of unsecure computers on unsecured networks all over the world. Here are some basic steps you can take to make sure your network is protected:
Wallace took his computer into a repair shop, and now he's concerned that they could have put monitoring software on his computer. This is a legitimate concern, and often times it happens remotely with people calling that claim to be from Microsoft or something. If someone has physical access to the system, though, all bets are off. Taking a computer into a repair shop is an absolute act of trust. There's not much he could do about it, though, if he needed to bring it in. There's no certification process or national organization of computer techs, so he'd just have to trust them.
