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. 

Is my network safe from ransomware?

Types of Ransomware

Episode 1714

Steve from Newport Beach, CA

Steve's data center got attacked by ransomware. Fortunately, they had two locations and was able to shut one down, clean it, and then reinstall with only 3 hours of downtime. Leo says that's fantastic. But a hot backup can let the ransomware spread to your backup. So the key is to keep the second network only connected every three hours. That will give time to take down the infected network before the next sync connection time. 

Ransomware hits huge international conglomerates

Types of Ransomware

Episode 1714

Norsk-Hydro, a huge international conglomerate was hit with ransomware, costing the company $60 million. The malware came from an innocent email that had been intercepted and altered to include malware that infected the network when opened. Encrypting all data. The malware infected the company in December but wasn't triggered until March. Norsk-Hydro had a cyber insurance policy that consistently tests the network, but they were infected anyway. The company decided not to pay and relied on backups to restore their network. But the damage had been done as the network was down for weeks.

Be Very Careful and Skeptical of Email Attachments, Even From "People" You Know

Most of the malware and ransomware that comes through the internet and onto our systems is thanks to email attachments. If you see an "invoice" with an artificially rushed, demanding tone from a powerful figure (such as your work boss) and they've attached a "PDF", be very skeptical and do not open it. The same goes for links, since they can take you to a very shady site. Make sure to update your computer with security patches to prevent infection from background exploit kits across the web.

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.

Leo says that while 2018 was the year Ransomware, 2019 is even worse. Arizona Beverages got hit by ransomware last week. The attack shut down sales operations for days, scuttled their networks, and servers. The network was hacked and encrypted, targeted by hackers with a ransom note posted to their website.  Leo says that Arizona struggled with trying to rebuild their operations for five days. Most of their servers hadn't been given security patches in years and their backups didn't work.

Petya is the Latest Ransomware Scam

Episode 1400

Petya is the latest ransomware hitting millions of computers around the world. Most infected computers are in the Ukraine, where "patient zero" is believed to be. From there it branched out to Russia, Poland, Italy and Germany. It takes advantage of the same flaws in Windows 10 that WannaCry did. Fortunately, it hasn't really hit the U.S. yet, but we'll see more infections as time goes on. Our CIA intelligence service discovered it and didn't say anything because it could use it to spy on others.
