Is Apple CarPlay secure in a rental car?

Episode 1747

Ed from Clairmore, OK

Ed rented a car recently and it came with Apple CarPlay. Is that secure? Leo says it is because Apple makes it really difficult to break encryption. You just want to be sure to remove your device after you're done with the car rental. Select "Forget Device." Or don't use the car's internal telematic systems. Just the CarPlay. 

There's also a setting in Apple CarPlay that says "do not copy my contacts" to the car. Make sure you enable that so your contacts won't get transferred to the car's hands-free system.

Episode 1731

Lori from Orange, CA

Lori googled how to remove remote access apps on her Mac, and she was able to remove them after Apple walked her through it. But she's worried that she didn't get it all. Leo says that if Apple took them off, it's a good chance Lori is fine. It's easy to get paranoid about a computer because it does a lot of things we don't understand. The only concern is that when Lori gave the original technician remote access, that he could've installed something else she doesn't know about. If she's really worried, she can always back up her data, format her hard drive, and then reinstall macOS.

Do I have malware?

Windows Defender

Episode 1730

Karen from Tri-Cities, WA

After getting a phishing scam email, Karen ran a malware scan with Windows Defender and it found a "severe threat" called a Trojan-Downloader. Windows Defender blocked it, but is she still compromised? Leo says that everyone gets those, and it's not a side effect of a virus on your system. So if Defender found one and blocked it, you're safe from it.

Episode 1727

Glen from California

Glen wants to know if ransomware can happen if you unplug your backup from the network. Leo says not until he plugs it back in. But it's less likely with a home-based system than say, a commercial network. So clean up the infected computer before reconnecting the backup, otherwise, it could infect it. A lot of ransomware also has time-released capability. It may not infect right away. So if Glen has backup unplugged from the network, he should keep it that way until he's wiped the hard drive and removed the ransomware.

Episode 1706

Ed from Huntington Beach, CA

Ed is worried because he got a warning that his data has been found on the dark web. What can he do about that? Leo says you can't really do anything. Data breaches happen all the time. You can change all your passwords, and Leo recommends doing that with your bank, and if your credit card number has been compromised, you can change that. But in most cases, the dark web compromise is mostly your email address, and that's it. 

Check out HaveIBeenPwned.com to see if your email information has been grabbed. 

Should I use NextDNS?

NextDNS

Episode 1702

Pete from Amesbury, MA

Pete heard about a device to keep his iPad private called NextDNS. Does it use a VPN? Leo says that DNS is essentially the internet address system in IP numbers. DNS is the phone book for it. NextDNS bypasses your ISP so that they don't know what you're browsing on. It will encrypt the traffic to NextDNS and back. But your browser is still visible. The thing about VPNs is that they are a tunnel that encrypts everything and slows things down. Leo uses NextDNS on all his devices, but you'll go through the free tier pretty quickly. But it's not very expensive.

Should I Uninstall My Adobe Flash Security Utility?

Episode 1697

Dino from Claremont, CA

Dino uses a label program to create address labels. But after an update, it stopped working. Support wants him to uninstall the Adobe Flash Security option. Leo says that's a problem because flash is a security issue itself and turning off the security app makes you vulnerable. Leo also recommends exporting out data and then finding a better label program.

How can I secure my WiFi router?

TP Link Router

Episode 1684

Bruce from Carlin, NV

Bruce wants to know how he can secure his WiFi router. Leo says to first enter the router address (198.x.x.x) and then change the default password. Then, turn off Administer via WLan. This will prevent someone from the outside controlling your router. Step 3, turn off UPNP (aka universal plug-in play). This prevents a device inside of your network, like an Xbox, opening up your router to the internet when you don't want it to. Lastly, turn on WPA2 security encryption.
