Malware, viruses, hacks, and anything else that may compromise your identity online, computer, or digital device.
Security and Privacy
José would like to be anonymous online. How can he minimize his online footprint with Mac addresses? Rich says that most systems are encrypted now, and Google is pushing all websites to update to https. So your traffic gets more encrypted. If that's not enough for you, then randomizing your Mac address is a good way to do it. In iOS 13, for instance, Apple devices generate randomized Mac addresses while online. That's a good way to keep yourself protected. You may try using a VPN, or you can browse privately.
William's computer was hacked and he knows who did it. He was the victim of a phishing scam that nabbed him after he clicked on an email link. Leo says William should change all his passwords, wipe his hard drive and start over. But call the police first. If you can prove the information, call the police and then bring the computer to them.
Larry is looking for a bitlocker type program for his Mac. Leo says that Mac has its own encryption built-in called FileOS. But if you want to encrypt a USB key, then a third-party app may be a better option. Samsung sells large portable SSDs in 1 and 2TB that come with the encryption included for both Windows and Mac. It's built-in. VeraCrypt is another. And it's free.
Dan signed up for a VPN recently, and he can't use it with his banking, Netflix or other apps. Leo says that the bank is probably blocking it. VPNs can break IP-based authentication. BBC iPlayer, for instance, blocks VPNs, because you're not paying for the TV license fee. Netflix does it because it doesn't want another region to be watching content that isn't available for licensing reasons. Banking activity is encrypted, so you don't really need a VPN for it. Google has also been pushing for HTTPS encryption with every site, so if every site is encrypted, there's no real need for VPNs.
Karen wants to know if putting a VPN on her router would keep her secure. Leo says that it would encrypt stuff in your network, but in order to get your traffic encrypted going out, you need to have the software on your desktop. Leo likes to use the Tiny Hardware Firewall VPN because it's in between your computer and the outside world. It's a great way to go.
Paul wants to know more about Mesh Routers and Internet of Things, but is concerned about security. Leo says that if you stick to main brands like Eero and Netgear, they will keep their firmware updated for security purposes. Leo recommends the Eero. But you may have to pay a monthly security subscription, which Leo hates.
Ben has an issue with 2-factor authentication. Leo says that text message 2-factor authentication isn't safe anymore because "sim jacking" can occur, by bad guys figuring out what your cellphone number is, and then using social engineering to get them to reassign that number to a new SIM. Once they do that, they have control of the mobile device and can control even 2-factor authentication. That's why Leo supports using an authenticator. He uses a hardware-based model called Authy.
Mike needs a good password manager that can also serve as a VPN. Is there any? Leo says he doesn't think that there is one, but that is a great idea. Leo recommends LastPass or 1Password for a good password vault. As for VPNs, there are a lot of options out there, but beware of free VPNs, because to make money, they sell their traffic. So it really isn't all that secure. Leo recommends ExpressVPN. There's also the Tiny Hardware Firewall.
Don wants to know why he has to download MP4 files in Windows 10 before playing them. Why can't he just stream them? He can just play them on his phone. Leo says it may be a setting in Windows. It may be due to file size. Leo says that downloading any attachments is inherently dangerous. Leo suggests never opening or clicking on an attachment.
Susan has a fighting studio, and she needs some security cameras. Preferably something wireless. Recommendations? Leo says that battery-powered cameras wouldn't work because they are motion-controlled. So Leo recommends cameras that are wired for AC power. He recommends the Google NEST Camera. But the downside is, that they're expensive and the monthly fee is required for storage. A better affordable option is WyzeCam. They start at $20. Offer night vision. Have two-way audio. And you can view them online.
