Have I been bit by ransomware?

Episode 1389

Grover from California
Google Chrome

Grover has a popup that says to call Microsoft Support. Has he been bit by ransomware? Leo says no, probably not. It's a phishing attack, but it's to try and get him to call in and then they charge him and access his computer. It's Scareware, really. He can ignore it, but it keeps popping up and he has to reboot his system to get rid of it. He even replaced the hard drive, but it didn't help.

WannaCry is the Latest Phishing Ransomware Attack

Episode 1389

WannaCry

The latest ransomware attack is called WannaCry and it's spreading via phishing email attacks. The ransomware not only encrypts your data — it also has a built-in kill switch on websites. Security researchers may have crafted a fix to it, but there's a catch. The encryption is done using Microsoft's bit locker, and the fix is to take advantage of a flaw in the cryptographic memory that keeps the keys in RAM so it can harvest them and unlock your data.

Val from Los Angeles, CA
LifeLock

Val is interested in LifeLock and wants to know if it's safe. Is it? Leo says yes.

But now they can't do that because of lawsuits. So now they own companies that are built to target fraudulent credit activity so that if anything unauthorized occurs, you get wind of it and they can shut it down. They will also help you fix your credit record should you be a victim of credit card fraud.

Hacker

Art opened his computer and something took control of Chrome and wouldn't let him shut down the app or his computer. Has he been hacked? Leo says not to panic.

Leo says that there's a lot of concern over the "internet of things," which includes cameras. They don't get updated very often. Foscam made cameras that were easily hackable, so Leo suggests not getting them. He won't want to get the low end, off brand stuff either. It won't be secure.
