As you know, I'm Eli, the computer guy, and today we're going to be talking about how to prevent ransomware.

So, as you know, fill in the blank is in the news yet again today.

So we're hearing about yet another ransomware attack.

And why I say fill in the blank is because, really, it seems like every 2 to 3 months we have another massive ransomware attack.

So we're talking about ransomware attacks, but we're talking about is essentially viruses or worms or malware that get into a person's computer.

They encrypt all the important files, all the important data on that person's computer.

And then, in order to be able to get the decryption key to be able to get those files back, you have to send off Bitcoin somewhere normally between $502,000 in Bitcoin, in order to theoretically get back the encryption key.

So this is the latest type of malware virus worm, and that is out there.

But this is some of the first malware that intentionally tries to get something out of the end user.

Maybe they'll try toe steal some specific information from your computer.

But realistically, with Ransomware, this is the first stuff that actually tries to extort money out of you.

Now, before we get into today's class, we do have to talk about the sponsors because the sponsors are what helps pay the bills and helps pay for silicon discourse dot com.

So we have Geist, Geist Build a Delivers rack P to use ultra quick as few as five days for standard units made in America.

Hashtag sexy Petey, use geist global dot com, The free backup for PC Zvi EMS and Lennox, all latvian dot com Dev Mountain Dev.

As I always say, Don't really care of your thumb up thumb down.

But if you click on those sponsor links below, that really does help everything that I try to do for you.

So when you're thinking about how to try to prevent ransomware, it's important.

Where is it is a new variant of malware viruses or worms?

Essentially, the only difference is, is that the attack, the action that it does on your computer is to encrypt your files, and then it tries to get you to send Bitcoin and order get to get that decryption key back.

So if you think of it as a piece of malware, a virus or a worm, it is much easier to understand how to prevent ransomware infections so that you don't have problems on your systems.

Essentially, all you have to do is if you have good security policies.

If you have good security practices, Ransomware essentially get self is a big thing you have to understand.

In the I T world, we always hear about the concepts of how do you prevent this, or how do you prevent that?

And what you find out is, if you have good security policies and practices, you put practices into use that that prevents a whole bunch of things all at the exact same time.

So when you're looking at trying to prevent ransomware now, one of the big things to think about is making sure you're using the latest version of the operating system for whatever operating system vendor you're using.

So if you're using a Mac, use the latest version of the Mac OS operating system.

If you're using windows, be using Windows 10 and whatever the latest version of Windows 10 is.

If you're using Lennox, use whatever the latest version of the specific distribution of Lennox that you're using Well, the important thing to understand is that when operating system vendors operates is the manufacturer's code.

They always code for the best security practices of the time.

So one of the reasons that Window's X P was so vulnerable to viruses and spyware and all that kind of stuff back in the day was that it simply was not designed for an era when everybody was going to have always on broadband connection.

So essentially about the exact same time when those x p came out and D.

And therefore Windows X P just got eviscerated with viruses and spyware.

The same is true for all of these different operating systems.

As they come out, they are built around a security concept for the time when they're being created.

Of course, when they come to market, things change.

New security issues come up, and so many times they have not been designed to be able to try to prevent those those new security issues.

So especially if you're looking at Windows, here's the deal a lot.

Some people love window stunts and people love wins.

I am not going to get into the middle of that argument here, but if you are using Windows.

For whatever reason, you have decided to use Windows.

You have already decided to be within the Microsoft ecosystem.

So at this point, going to Windows 10 really is your best option.

I know a lot of people are still using Windows seven.

Some people using Windows eight Windows 10 has been built with the best security policies that Microsoft understood while they were creating it.

And so for a lot of issues that will come up if you're using the latest version of the Microsoft operating system or whatever operating system, it will prevent a lot of problems.

One of the issues with Windows XB is there's still a lot of Windows X P in the world, and the issue is is that it was not built for the modern world.

There's a lot of problems that can get into Windows X p that will simply never be fixed.

So I know if you love Window seven, if you love Window seven, it's hard to give it up.

But you really have to be thinking about it.

If you've already decided to use Microsoft anyway, you've already you've already made that decision.

Not going up the Windows 10 At this point, I would argue from a security standpoint, especially when we start looking these ransom, where these new attacks that are being presented you should be up on the latest Microsoft operating system because here's the thing.

If you don't trust Window is dead, What does that say about you know, a 67 year old Window seven operating system?

The next thing past, making sure that you're using the latest version of whatever operating system is that you make sure all of the software and the operating system itself is updated on your system.

So again, whenever, whenever a piece of software goes out into the the two to use in the world many times there are vulnerabilities with that software that will be fixed by patches or updates down the road.

So Microsoft will put out a new operating system, and then anybody knows if it's a year after that operate system came out, you're gonna have to you have to download three hours worth of updates.

There's different worms, is different now where there's different issues, different exploits, Microsoft or any of the vendors find out about those exploits once their product is out in the wild, and then they come up with solutions for that.

So it's very important to make sure that your Windows operating system or any of your operating systems are fully updated.

But it's also important that all of the other software on your computer is updated.

If you have job a few still not using Adobe Reader God help you for still using Adobe Flash.

Make sure all of your products on your computer are fully updated because many times hackers, malware viruses will be able to get in through little known issues in that old software.

This is something I used to see back in the old days where Java became very popular in the beginning of the two thousands.

But then people stop using it well, since people stop using it of people had Java installed on their computers, and then they forgot about it.

All right, if you're not, if you're never using Java applications and you have job installed, you don't think about it anymore.

And so what hackers were able to dio is they were able to exploit vulnerabilities and five and six year old versions of Java that people still had running on their computers cause all kinds of problems because nobody even thought about updating job.

So this is something to be thinking about.

Make sure you do patch management, especially if you're in a large enterprise environment.

Make sure you have some kind of patch management infrastructure, maybe something like secure nya.

That'll go out and scan all of the different PCs, all the different computers on your infrastructure and make sure everything is up to date.

Patch management is a huge issue when it comes to trying to prevent things like Ransomware.

The next thing you need to dio if you're thinking about trying to prevent something like Ransomware is do software audits on all of your PCs or if you only have one PC, do it on your PC.

One issue that comes up is a lot of people when they think about cleaning up their computers, what they do is they go through and they delete Thea the Recycle bin all the stuff in the recycle bin.

But what they will never do is uninstall applications that they don't use anymore as the example I talked about before.

If you have a Java, if you have Adobe Flash, if you have Adobe Acrobat, if you have some other kind of old software on your PC or your computer, that could be a vulnerability to your computer, and especially if you never use it.
