Is my computer vulnerable to attack?

Wireshark

Episode 1601

Jim from Wisconsin

Jim ran GRC Shields Up scanner on his router and he discovered that port 443 was open, not stealth. Is he vulnerable? Leo says you have to have port 443 to run on the internet, but it should be in "stealth mode." You'll also want to find out what's using it. NetStat will help you determine that. Wireshark will also do that. His fan is also running a lot. Leo says that may mean your computer is getting hotter. Probably needs to have the dust cleaned out of it.

How Can I Set Up a VPN at Home?

VPN

Episode 1600

Tom from Warren, OH

Tom wants to set up a virtual private network at home. How can he do that? He's worried about getting bit by ransomware. Will a VPN prevent that? Leo says that no. If you click on something, a VPN can't help you. But a VPN will keep your traffic private, so no one can see where you're going. But even then, it has its limitations. While it burrows an encrypted tunnel to where you're going, once you get there, it's no longer encrypted. So you have to trust that where you're going will keep your privacy. And your provider still sees your traffic. 

GotoMyPC or RemotePC?

RemotePC

Episode 1598

Alice from Los Angeles, CA

Alice wants to know which remote software to use. RemotePC or GotoMyPC? Leo says that they're very similar and both do the same thing. RemotePC is an advertiser but is half the price of GotoMyPC. And they have a free trial before you buy.

If you have Windows 10 Professional edition, it comes with its own remote access options, but there is a known security flaw in it, and Leo recommends waiting until Microsoft fixes it. 

Has my Google Home Hub been hacked?

Google Home

Episode 1596

Pat from Los Angeles, CA

Pat has a google home hub and she thinks it's been hacked. What can she do? Leo says that it's likely that someone has hacked Pat's Google account. Leo recommends changing her password and turning on 2-factor authentication. Add an account recovery number and email as well. That will keep someone from changing your password. Leo also recommends turning off "share your device" in the settings and set up Voice Match. 

Is public wifi at a hospital safe?

Netgear AC1200 Dual Band WiFi Router

Episode 1589

Gordon from Long Island, California

Gordon is in the hospital, and wants to know if their public wifi is safe or should he use a VPN? Leo says that if it's using a wide-open network, then anyone can log in. It's a shared, public network. There are some risks, but your banking is safe because it's encrypted. The one thing to worry about is a "man in the middle" attack. Hospitals with public wifis could give the hospital the ability to watch what you do. That's when a VPN can come in handy. It will encrypt all traffic, by burrowing an encrypted tunnel to the internet. 

Is Ransomware Really Covered by Homeowners Insurance?

CHUBB

Episode 1588

Murray from New Jersey

Murray's home owner's insurance is now covering cyber-related incidents, including ransomware at up to $250k. What does Leo think? Leo says that's interesting because many insurance companies have declined to cover it because it's considered an "act of war" as part of a nation state's cyber warfare campaign. So Murray would have to read the policy very carefully to be sure there isn't an act of war clause that they can use to get out of paying any losses. Leo says that LifeLock will cover him up to $1 million with their backup service.
