Steve is worried he's being spied upon online. He gets a popup on his 4G data connection that says "network may be monitored by a third party." Leo says that's exactly what Superfish has been doing. Certificates get issued by various browser authorities like Google. If you don't like it, then try another browser.Often though, the most common cause of expired certificates is a dying battery that keeps track of your computer time. It will cause the certificate to appear out of date.
Leo had talked to Mark Goodman, the author of a book called "Future Crimes," who is a former LAPD officer that got roped into computer forensics early on. This book is a good look at where we stand right now in global security and what we can do about it. One of the reasons Leo wants to recommend the website, FutureCrimesBook.com, is because there's a really good section of it called "The UPDATE Protocol." This echoes things Leo has said for a long time on the show, and it's all in one place.
Les is interested in Touch ID and how it can be used with laptops. Why hasn't Apple integrated this into computers yet? Leo says that Touch ID is a great new feature in the iPhone, and a better fingerprint reader is coming to the Samsung Galaxy S6 too. But if Apple doesn't see a market for it on a computer, they won't offer it. But if they notice others doing it, then Apple will swoop in and do it better.
Some are using the Knock app, but Leo's had mixed results with it. The chatroom says the Mac ID app will do it.
Nuris has an Alcatel phone and her mom is getting weird texts. Leo says that it sounds like someone else is texting her, and it could easily be someone texting the wrong number. Leo has a hunch that T-Mobile has crossed a few wires, and they'll need to fix it.
Elizabeth got an email from her friend that included suspicious links, and she's wondering if his email account was spoofed. She looked in the header, but didn't see anything. How can she find out if it was spoofed? Leo says the tale is the CCs. They would only be able to put so many addresses in a field, and if they are using multiple fields, then she'll know the person has cracked the account. Yahoo has always had security issues. So the account has been hacked and there's all kinds of ways to do it. First thing to do is change the password, and make it a difficult one.
Cecil is using LastPass and wonders if he's safe using it even on a public Wi-Fi access point, like a hotel. Leo says absolutely. It encrypts all of his passwords and he'll be safe that way. Not even LastPass knows what his password is.
He should make sure he's also encrypting his email. Google is planning to do that through Android later this year.
Hackers broke into the Anthem Health database to obtain names, birthdays, addresses, and Social Security numbers of customers. An estimated 80,000,000 records have been lost. After the hack, there have been phishing scams circulating and phone fraudsters calling people to obtain financial information. If you do get an email from Anthem, do not click the links, go directly to the Anthem website. If you get a call from someone claiming to be from Anthem, hang up and call them back using their posted phone number.
Jay wants to know if removing viruses is the same between Mac and Windows. Leo says that there's a debate that Macs are either more secure, or are a smaller target because there are fewer of them. Leo says that malware writers are going to write for the largest segment of computers. But OS X is based on Unix and that's more secure than Windows. OS X also has an administrator requirement when installing software.
Mike wants to keep his kids safe online that won't slow down the computer. What can he use? Leo says that when they get older, kids can figure out how to bypass restrictions. But when they are younger, they are OK. Leo advises using OpenDNS with his router. He can put things on computers, but they really aren't effective and filters often block things that he won't want blocked. But OpenDNS will allow him to change how the router will find webpages and block sites that he doesn't want. And he'll have complete control.
Dan has been getting messages to update Java, but he's worried about security. Leo says that since Dan uses Windows XP, there is a security issue because Microsoft doesn't support it anymore. Google will update Chrome, so it's a good idea to use that as his browser. But he shouldn't use Java unless he needs to. If he does need to use it, he should make sure he installs all security patches. He should disable the browser plugin as well, and he should run Windows as a limited user -- not as Administrator.
