Speaker:

You found the backup wrap up your go-to podcast for all things

Speaker:

backup recovery and cyber recovery.

Speaker:

In this episode, we talk about detecting ransomware with cyber

Speaker:

threats evolving at a breakneck speed.

Speaker:

Understanding how to spot the early signs of a ransomware

Speaker:

attack is more crucial than ever.

Speaker:

We're once again joined by cybersecurity expert Dr.

Speaker:

Mike Sailor, who shares invaluable insights on the subtle indicators of

Speaker:

ransomware activity from performance degradation to unusual network behavior.

Speaker:

We'll explore the role of SIM and XDR tools in early detection.

Speaker:

And discuss why a rapid response is your best defense against

Speaker:

these malicious attacks.

Speaker:

By the way, if you have no idea who I am, welcome to the podcast.

Speaker:

I'm w Curtis Preston, AKA, Mr.

Speaker:

Backup, and I've been specializing in backup and recovery all the way back to

Speaker:

30 years ago when I could not restore a database because our backups were broken.

Speaker:

I, I hated having to tell that to my boss, and I don't want you to have to tell that

Speaker:

to your boss, so that's why I do this.

Speaker:

On this podcast, we turn unappreciated backup admins into Cyber Recovery Heroes.

Speaker:

This is the backup wrap up.

Speaker:

Welcome to the show.

Speaker:

If I could ask you to take a quick second to press that subscribe or

Speaker:

follow button so that you can always get our content, that would be great.

Speaker:

I am w Curtis Preston, otherwise known as Mr.

Speaker:

Backup, and have with me a guy who almost lost his head today.

Speaker:

Prasanna Malaiyandi guys are going.

Speaker:

Persona, we're we're glad that you're alive.

Speaker:

Yeah, I, uh, I escaped without an losing any fingers or my head,

Speaker:

you know, so that's a, it's a good day, you know, I'll take that

Speaker:

anytime of the day.

Speaker:

so why don't you tell the listeners why we had to delay this recording?

Speaker:

What happened to you?

Speaker:

so I was walking by and getting tea before the podcast and I was like, oh.

Speaker:

And I looked up at the ceiling and we have in our kitchen, we have a ceiling fan.

Speaker:

And I was like, huh, that's weird.

Speaker:

What's that blue piece and why does it look a little tilted?

Speaker:

So luckily I got a chair a step stool and I was like, huh, lemme take a closer look.

Speaker:

And I literally touched it.

Speaker:

And then the thing like fell down and was just dangling by the three wires, right?

Speaker:

The ground, the hot, and uh.

Speaker:

I was like, uh, then I had to quickly call my wife and it's very awkward.

Speaker:

Like these are like 30 pounds, right?

Speaker:

And it's hanging above you.

Speaker:

And I was on a short step stool and I was like, how do

Speaker:

I actually unclip these wires?

Speaker:

And it was a whole fiasco with, uh, ladders and step stools and

Speaker:

all sorts of things in order

Speaker:

to be able to do it.

Speaker:

But I have it down, which is good.

Speaker:

Yeah.

Speaker:

And an anxious wife hanging over to the side.

Speaker:

Uh, do, do you think you're gonna be replacing the fan?

Speaker:

Well, like with the new fan or just

Speaker:

it's, it's gone.

Speaker:

It's gone.

Speaker:

It's

Speaker:

Okay.

Speaker:

going to just put a normal like, 'cause honestly lived here for 11 years

Speaker:

now, 10 years, something like that.

Speaker:

And I think we've only used that fan once

Speaker:

Yeah.

Speaker:

It, it, it's funny, you know, it's funny, you, you know, I recently

Speaker:

replaced my ceiling fan with, in the kitchen with a, with just a light.

Speaker:

And what I remember was I, when I wanted to take it off,

Speaker:

I just could not figure out, I.

Speaker:

How to get it out, like what I was supposed to do to get

Speaker:

it out of there properly.

Speaker:

Um, and I wish that it was just hanging by the three wires.

Speaker:

It was like, it was just, I, I just remember that a saal,

Speaker:

uh, was involved at one point.

Speaker:

Yeah.

Speaker:

Well, and the hard part with that is like, it's like it's bulky and then

Speaker:

I saw the fan blades attached and like you can't see anything, right?

Speaker:

Because they hide all the things and it's like, okay, how do

Speaker:

Yeah.

Speaker:

off this trim piece so then I can get to the screws to unscrew it?

Speaker:

But like you said, luckily because my outlet box head basically

Speaker:

detached itself from its support, it was just kind of hanging there.

Speaker:

And so it made work a little easier.

Speaker:

'cause yeah,

Speaker:

Well, we're.

Speaker:

attached, I don't think I could have figured that out.

Speaker:

I am glad that you survived, and I'm glad that for once it's one of the stories from

Speaker:

your house rather than stories from my house that we're featuring on the episode.

Speaker:

Yeah.

Speaker:

So, speaking of stories, we once again have Dr.

Speaker:

Mike Sailor with us.

Speaker:

Our, our, at this point, resident cyber expert.

Speaker:

How's it going, Mike?

Speaker:

That's going well guys.

Speaker:

How are y'all?

Speaker:

Well, we're alive.

Speaker:

But, uh, this week I wanted to jump right into this idea of

Speaker:

ransomware detection, right?

Speaker:

So we, we, we tell people that they should assume breach, right?

Speaker:

That they should assume they're going to be attacked, and, uh,

Speaker:

because statistically speaking, they, they probably will be.

Speaker:

And you've dealt with a lot of these attacks.

Speaker:

So, so, um, I, I, I wanna understand, you know, what, what does.

Speaker:

What does a ransomware attack look like?

Speaker:

Right?

Speaker:

Like, what are the things that people see that are going on that don't like?

Speaker:

If, obviously if you get a, you know, a big thing on your screen that

Speaker:

says, Hey, give us a million dollars.

Speaker:

We're gonna get your, you know, get your files back.

Speaker:

That's one way to know you have ransomware attack, but what other

Speaker:

things happen before that that tell you that you have a ransomware attack?

Speaker:

Is it is a ceiling fan if a ceiling fan starts to fall?

Speaker:

Is that, is that,

Speaker:

I think,

Speaker:

is that.

Speaker:

I think before Mike, before you jump into that, Curtis, maybe it might be a

Speaker:

good idea just 'cause I think listeners may not be listening to every episode

Speaker:

in order, it might be a good idea to say like, why Mike is on the podcast

Speaker:

and why he's the expert in this area.

Speaker:

Right.

Speaker:

Well,

Speaker:

talking about ransomware detection, or Mike, maybe you wanna cover that.

Speaker:

yeah, go ahead, Mike.

Speaker:

Uh, certainly, so happy to, happy to, uh, comment on all of those things.

Speaker:

Uh, I think my experience over the last probably at least 20 years, uh, responding

Speaker:

to incidents both at, know, uh, personal, uh, at the personal level, uh, whether

Speaker:

it's a family member or somebody referred.

Speaker:

someone to us to, to help with a, a problem, uh, or a corporate, uh, level.

Speaker:

And, and that's, you know, school districts, banks, um, normal business

Speaker:

enterprise that, uh, have incurred some, uh, some cyber incident.

Speaker:

Uh.

Speaker:

We, we've seen quite a bit of, uh, variety of incidents, uh,

Speaker:

especially around ransomware.

Speaker:

There's, there's a hundreds of different variants of ransomware.

Speaker:

Uh, there's the more popular ones that we've probably seen more often

Speaker:

than the others, and there are some consistent themes and, uh, you

Speaker:

know, potholes and lessons learned.

Speaker:

And, and, uh, when, when someone that's seen it before, uh, shows up

Speaker:

to help put out the fire, we know where to where to put the water first.

Speaker:

Uh, what not to put water on, uh, when to ask for help and who else

Speaker:

to, uh, who else to involve in that.

Speaker:

So,

Speaker:

So, so

Speaker:

happy

Speaker:

know?

Speaker:

of.

Speaker:

Go ahead.

Speaker:

Finish.

Speaker:

Yeah.

Speaker:

to share, to share my experience and some stories.

Speaker:

Yeah.

Speaker:

So unlike me who's a YouTube person, you're actually

Speaker:

like, grounds on the boots.

Speaker:

Someone who's actually lived and does, does this on a like day to day basis

Speaker:

Uh, absolutely.

Speaker:

And, uh, you said grounds on the boots.

Speaker:

And the first, the

Speaker:

Yeah.

Speaker:

I

Speaker:

on the

Speaker:

thought.

Speaker:

Boots on the ground.

Speaker:

Yeah.

Speaker:

Uh, well, and, and first thing I thought of is that needs to

Speaker:

be a t-shirt at a coffee shop.

Speaker:

I think that would be good, uh, because I'm a, I'm an avid coffee

Speaker:

person, so that made sense to me, even though you said it that way.

Speaker:

But absolutely.

Speaker:

I've, I'm, uh.

Speaker:

Uh, in addition to being hands-on, you know, years ago in, in rebuilding

Speaker:

machines and actually, you know, type it in commands and running

Speaker:

tools, uh, to today, I'm more of what they consider a, a breach coach.

Speaker:

Uh, so you've had an incident, uh, and I'm just there to, to try and herd the

Speaker:

cats and give up updates in a, in a correct and, and less stressful manner.

Speaker:

Uh, be the one there that, that's already had my hair burned off while

Speaker:

everybody else is running around on fire.

Speaker:

Uh.

Speaker:

So d uh, Mike, uh, during the pre-call, you uh, had mentioned how different.

Speaker:

Like a ran like ransom, how different ransomware is from other malware,

Speaker:

and I think that's probably a good place to start before we talk about

Speaker:

what an attack actually looks like.

Speaker:

Sure.

Speaker:

Well, you know, malware in general, just bad software.

Speaker:

Uh, you know, it's, it's intended to do nefarious things or,

Speaker:

or trick us or steal from us.

Speaker:

Um, and, and there are elements of, of malware that are consistent

Speaker:

across different types of malware.

Speaker:

It's like info Steeler, malware.

Speaker:

Uh, harvesting malware that, you know, captures your keystrokes

Speaker:

or looks for certain things.

Speaker:

There's malware that just does reconnaissance.

Speaker:

Uh, and so when you think of really bad malware, it has the worst of

Speaker:

all these elements, uh, combined.

Speaker:

And effective ransomware these days really does.

Speaker:

Uh.

Speaker:

Perform in different phases.

Speaker:

So the first phase is it wants to gain access to, to whatever it's infected.

Speaker:

So that computer, your, your smartphone, that server, whatever it might be.

Speaker:

And then it wants to figure out, well, what do I have access to?

Speaker:

so was it a, a particular user, user account that.

Speaker:

Allowed it to infect this device.

Speaker:

Uh, what does this device then, and, and that user profile have

Speaker:

access to across a network?

Speaker:

Uh, what type of, um, software or files are on this machine?

Speaker:

For example, there is a specific ransomware that only

Speaker:

targets point of sale systems.

Speaker:

And so if, if it infects my laptop, it's gonna determine whether my

Speaker:

laptop is a point of sale system.

Speaker:

And if it is not.

Speaker:

It's gonna look for a way to spread to the next system, and once it does,

Speaker:

it will clean itself off of my laptop.

Speaker:

So as if it were never there.

Speaker:

And then it will continue doing so until it finds a point of sale

Speaker:

system and then it will deploy.

Speaker:

Its, its ransomware, you know, whatever, additional software

Speaker:

and, capabilities it has.

Speaker:

But there's those first few phases of what, what do I have access to?

Speaker:

And what, um, what can I, you know, what value, uh, aligned with my

Speaker:

ransomware campaign, uh, does that bring me, that then, uh, triggers

Speaker:

a whole slew of other things.

Speaker:

Like, okay, so I found I found a point of sale system.

Speaker:

Do I still have internet access?

Speaker:

And if I do, I'm gonna reach out and download the next, the next

Speaker:

piece of malware I need specific to the point of sale system I found.

Speaker:

And so.

Speaker:

A lot of times that initial malware, ransomware infection is a very, what we,

Speaker:

we call a thin or light, uh, payload.

Speaker:

It's not very large.

Speaker:

It doesn't draw a lot of attention.

Speaker:

It doesn't do a whole lot other than determine whether it, it,

Speaker:

it has access to whatever this ransomware actor is interested in.

Speaker:

And then it'll phone home and say, Hey, I've got, I've got the goods.

Speaker:

Send the, send the next, send the next payload and we'll get started.

Speaker:

For that first phase, I know we're talking about ransomware detection.

Speaker:

Is there anything you could really do to detect, I know you said it's a

Speaker:

very lightweight, thin shim, right?

Speaker:

That gets installed, deployed.

Speaker:

Are there things people can do to detect at that phase?

Speaker:

There are and, and there are some symptoms, uh, ransom.

Speaker:

These, these first few phases are different from, uh, one ransomware

Speaker:

variant to, or even just malware in general, from one variant to another.

Speaker:

But they're, they do consume resources and, you know, to, to do reconnaissance,

Speaker:

to, to do a system inventory.

Speaker:

There will be a change in resource utilization.

Speaker:

CPU may go up, memory may go up, drive io may go up, network IO may go up.

Speaker:

And so if you have the ability to monitor those things, uh, and, and it

Speaker:

may not be much, but you know, set some thresholds that say if my system resources

Speaker:

go above whatever it is, let me know.

Speaker:

That may be because you're watching a movie, but at least you know it's because

Speaker:

you're watching a movie I'm typing, you know, a new chapter to my book,

Speaker:

and then all of a sudden my CPU spikes.

Speaker:

Well, I'm not doing anything that would justify that.

Speaker:

So let me go look at what processes are running and, and so on.

Speaker:

Well, for the normal person or even the normal technical person, you know, I

Speaker:

could go look at Windows processes and not know what 95% of those are, but I

Speaker:

could potentially kill that process.

Speaker:

maybe dig into where, where, well, what spawned that process?

Speaker:

Where's that file and what folder is it in?

Speaker:

And when did, what's the time and date stamp that, that that happened?

Speaker:

And was that something I did?

Speaker:

some things you can do, um, investigatively and you'll, it's

Speaker:

probably a learning process as you do it.

Speaker:

But then there are other tools, like that's, that's kind of what

Speaker:

Black Swan Cybersecurity does.

Speaker:

We monitor environments and in, in our monitoring, we create a.

Speaker:

Behavioral baseline by user, by device, by network segment.

Speaker:

And as weird stuff happens, it flags to us.

Speaker:

Because it's simply deviated from normal behavior before

Speaker:

it becomes a security problem.

Speaker:

So then we can call the client or the tech support person or the whoever

Speaker:

it is and say, let's dig into this and figure out, uh, if this is, uh,

Speaker:

if this is legitimate activity or, or what can we tie it to from a user.

Speaker:

Maybe some user clicked on a link or downloaded a file, and

Speaker:

that's what led up to this.

Speaker:

And so there, there are, there are tools out there and it ranges from.

Speaker:

You know, put your toolbox together and run, run script one and look at,

Speaker:

you know, report B and tie all that stuff together, which is kind of time

Speaker:

consuming, but low cost, no cost, uh, to, to more of the elaborate

Speaker:

capabilities of hiring a, a managed service to, watch over all that stuff.

Speaker:

Hang on.

Speaker:

I'm not sure where I wanted to go from there.

Speaker:

Nevermind.

Speaker:

Nevermind.

Speaker:

I'll um,

Speaker:

Well, well back

Speaker:

uh,

Speaker:

back to the kind of the, the, the attack progression and this, this lines

Speaker:

up with the Mitre attack framework.

Speaker:

You know, reconnaissance is always first, and then how do we, I.

Speaker:

Maintain our access.

Speaker:

'cause that's, that's second part.

Speaker:

Once I've infected you, I wanna make sure that if you've determined I've

Speaker:

infected you and you try to clean me off, I'm still infecting you.

Speaker:

so once you reboot, I'm, I'm still there, and I'm gonna be there until

Speaker:

you throw this computer out the window.

Speaker:

Uh, and so persistence is next.

Speaker:

And then, uh, you know, some of the other, other phases.

Speaker:

And as, as that.

Speaker:

Attack progresses through the Mitre attack framework, and it, it's

Speaker:

all mapped out regardless of, of the attack who's doing the attack.

Speaker:

It, it falls into these categories, these phases, and as that phase progresses,

Speaker:

resource and network and, um, symptomatic, uh, identifiers will always increase.

Speaker:

So the more activity, the further along that attack framework they get,

Speaker:

the more identifiable, uh, it is.

Speaker:

And so.

Speaker:

Um,

Speaker:

Hey Mike, you, you threw out the Mitre Attack framework.

Speaker:

Not everybody, uh, is gonna be familiar with that.

Speaker:

You want to talk about that?

Speaker:

so Mitre, which is an organization, um, a framework within which, and there, and

Speaker:

there's like seven phases, within which every attack sequence can be mapped.

Speaker:

And so almost every attack starts with reconnaissance.

Speaker:

Uh, what do, what did they gain access to?

Speaker:

All the way through, like data exfiltration.

Speaker:

Uh, so they've, they've got access to your stuff and they're stealing it.

Speaker:

and so the, the attack framework is simply a way of, of identifying not only,

Speaker:

uh, where an attack is, but how far did it go, and based on those attributes,

Speaker:

then how big of a problem did we just.

Speaker:

you know, how big of a, how big of a, a, an issue is this.

Speaker:

Um, but it also then allows you to align your response to those

Speaker:

different phases of the framework.

Speaker:

So in reconnaissance, what's my response?

Speaker:

Well, maybe just passive for now.

Speaker:

What is doing this reconnaissance?

Speaker:

Is it normal like internet, uh, pings just to see if a website's

Speaker:

alive that could be reconnaissance.

Speaker:

or is it something a lot more active, uh, where they're doing port scans and.

Speaker:

some active enumeration.

Speaker:

What, you know what, um, I, I pinged this IP and I've, I've

Speaker:

determined these ports are open and they're responding a certain way.

Speaker:

So now I know it's a Windows seven or, or Windows 2018 server, uh, running,

Speaker:

you know, whichever patch level.

Speaker:

And so that's active reconnaissance and that's a no-no.

Speaker:

so what's doing that and can we address it now versus, uh.

Speaker:

Waiting until that progre, that attack progresses into one of the other phases,

Speaker:

which could get a little more, uh, complicated as far as responding to it.

Speaker:

But then you would have kinda your playbook lined up with what phase of the

Speaker:

framework, what phase of the attack are we in, and here are the tools and things

Speaker:

we should, be applying at this point.

Speaker:

Uh, and some of those are management decisions, like cut the hard

Speaker:

wire, you know, uh, it's that bad.

Speaker:

Uh.

Speaker:

But you would want all that stuff kind of mapped out and

Speaker:

planned out, uh, ahead of time.

Speaker:

And that's kind of, you know, I think we touch on that in a different episode

Speaker:

and being prepared for, for game day and having your, having your team on

Speaker:

the same page and, and knowing what to do when certain things happen.

Speaker:

Do you ever see, like, this is fascinating to me, by the way.

Speaker:

I haven't dealt a lot into the security side, so it's kind of cool and it reminds

Speaker:

me a lot of TV shows to some extent.

Speaker:

Uh, the question I had though is I know that you could try to stop an

Speaker:

attack early on, like you said, right?

Speaker:

If you detect it early on, you could probably stop it before harm comes.

Speaker:

But at the same time, if you don't know what they're after, isn't that also

Speaker:

kind of a downside because they might figure out a different attack vector to

Speaker:

come back back at you through, right.

Speaker:

So is that some of the risk trade-offs that happens at like a

Speaker:

business level that the business sort of needs to make that decision?

Speaker:

Absolutely.

Speaker:

And that's the, so there's, there's value in, in exactly what you said.

Speaker:

Um, you know, if I had, if I had a thousand things to protect.

Speaker:

And I only had a thousand dollars to protect them then without knowing

Speaker:

the value of all that stuff and what I really need to protect,

Speaker:

and I'm gonna give a dollar of a protection to all thousand things.

Speaker:

if business says out of these thousand things, 10 of them are the most

Speaker:

critical for us to maintain business operations and continue making money

Speaker:

and make sure the lights are on tomorrow, then I'm gonna reallocate.

Speaker:

Proportionately that a thousand dollars of security funding to

Speaker:

protect primarily these 10 things.

Speaker:

And then some, maybe, uh, diluted version of, you know, decent cyber

Speaker:

hygiene to the other, you know, 990, uh, because they are layers between

Speaker:

bad guys in the outside world and these 10 things that we care about.

Speaker:

So we need some tools and, and capabilities on those other 990 things.

Speaker:

But I'm gonna focus most of my, my resources on the,

Speaker:

the, the jewels, if you will.

Speaker:

Yeah.

Speaker:

and that's just part of what we would consider a business impact analysis.

Speaker:

Where's the, where's the critical stuff?

Speaker:

Well, the other part of that analysis would be what is the financial impact?

Speaker:

What is the business and operational impact if these things are infected

Speaker:

or, or compromised or unavailable?

Speaker:

Is that a thousand dollars an hour?

Speaker:

Is it a million dollars a day?

Speaker:

I.

Speaker:

How, and then how many, how fast do I have to to get things back up and running?

Speaker:

Because, you know, let's say we, we, we lose those 10 things to

Speaker:

ransomware and the bad guys want $7 million, uh, to help you recover that.

Speaker:

Well, the business could go, all right, so they want 7 million.

Speaker:

We've got 5 million in insurance.

Speaker:

Um, insurance says they'll cover it.

Speaker:

So we're out 2 million.

Speaker:

If we don't recover this within a week, we're out 10 million because

Speaker:

that's how much money we're gonna lose.

Speaker:

then the IT guys and, and all of our subject matter experts are telling me

Speaker:

that we can rebuild this whole thing for 10 million or maybe 9 million.

Speaker:

So do we do it on our own and invest in X, Y, Z?

Speaker:

Do we pay the bad guys who.

Speaker:

no guarantee there either.

Speaker:

or do we just suffer through it for a week and we're out X dollars while we

Speaker:

try to rebuild it and recover on our own?

Speaker:

So that's, that's the business side of ransomware and some of these

Speaker:

cyber breaches that it, and subject matter experts like my, we're just

Speaker:

giving business intelligence for them to then make the decision.

Speaker:

Paying the ransom should never be an IT decision.

Speaker:

I.

Speaker:

guy, the

Speaker:

Yeah,

Speaker:

said, we're not the one going.

Speaker:

Yeah, pay the ransom.

Speaker:

We're giving the business, the executive team, the information

Speaker:

they need to make that decision.

Speaker:

Yeah.

Speaker:

Sorry

Speaker:

agreed.

Speaker:

we went off on a tangent, but.

Speaker:

That's all right.

Speaker:

That's all right.

Speaker:

Um.

Speaker:

So, so, so let's, let me get a sort of what I, what I think would be an

Speaker:

interesting part of this episode.

Speaker:

Not saying this, this wasn't interesting, but a, a, a fascinating part is you,

Speaker:

you, you've seen a bunch of attacks.

Speaker:

What are some of the like, weird things that we're going on that ultimately, um.

Speaker:

You know, ended up being ransomware attacks, right?

Speaker:

It's like they see this weird thing going on, and then eventually what

Speaker:

they figured out was, oh, well, it's because we have ransomware.

Speaker:

because always what I hear, sorry Mike, before you continue, always what I hear

Speaker:

is like, oh, all of a sudden I couldn't access files because they were all

Speaker:

encrypted, or things like that, which is like way, I'm guessing further downstream.

Speaker:

Right?

Speaker:

And I'm sure you have a lot of interesting stories about, hey, this, this, or this.

Speaker:

Uh, you are right.

Speaker:

It, it, it's, it's usually never, uh, a phone call with someone saying, I was

Speaker:

in the middle of doing X, Y, and Z and all of a sudden I, I, things changed.

Speaker:

It's, it's rarely ever that.

Speaker:

And bad guys know this, so if, if bad guys tip their, their hand

Speaker:

when people are at the console,

Speaker:

the response to that is, is gonna be pretty immediate.

Speaker:

Right.

Speaker:

want, don't want that.

Speaker:

They want, they want your response to be delayed to some degree, hours, days.

Speaker:

they also want to be conscious and even considerate in some cases.

Speaker:

sure that you can, some to some degree have the ability to recover with minimal

Speaker:

impact because they want you to, they want to, they want to be your friend.

Speaker:

They want, Hey, I did this on a Friday.

Speaker:

So you've got the weekend to recover, and so if by Monday you decide to

Speaker:

pay the ransom, everything's fine.

Speaker:

Right?

Speaker:

So ransomware attacks usually trigger Thursday, Friday,

Speaker:

Yeah.

Speaker:

It's usually not in the middle of the day.

Speaker:

It's usually first thing in the morning or in the middle of the night.

Speaker:

it's when you come to work and you notice your computer's useless.

Speaker:

It's when the middle of the night, uh, your, your batch

Speaker:

processes, your batch jobs fail.

Speaker:

And they know that a lot of organizations, well, I'll just check

Speaker:

on it in the morning when I get there.

Speaker:

Right.

Speaker:

so they've had hours to, to de to plan and deploy their ransomware

Speaker:

to do as much damage as they can.

Speaker:

Uh, so there's that part.

Speaker:

And then Curtis asked about some of the things that we've seen and

Speaker:

we've seen, we've seen quite a, a few different interesting things.

Speaker:

Uh, and one of the things I'll touch on too is, uh, initially

Speaker:

you asked, well, how do we notice?

Speaker:

Notice these things?

Speaker:

How do we know if we have ransomware?

Speaker:

Well, you'll notice, uh, a small degradation in performance.

Speaker:

If you are watching a movie as an example, if you're streaming

Speaker:

something, you might see some glitches.

Speaker:

and you're like, that's weird.

Speaker:

I've got fiber to my house.

Speaker:

Why?

Speaker:

Why is it glitching?

Speaker:

well, it's not the internet.

Speaker:

It's, it's, it's the resources on your computer being consumed by other stuff.

Speaker:

So there's some symptomatic stuff that, that's observable.

Speaker:

Well, then on the, um.

Speaker:

Network behavior side, especially if you're a, uh,

Speaker:

a public sector entity, like a school district.

Speaker:

are information sharing and analysis centers called ISACs.

Speaker:

There's a multi-state There's, uh, the state of Texas has its own called DIR.

Speaker:

if you're in a specific sector like financial sector, there's

Speaker:

a finance, a finance isac.

Speaker:

There's one for healthcare credit unions.

Speaker:

Auto dealerships and they all monitor the organizations that belong to their isac.

Speaker:

And so in the state of Texas as an example, they might call a school district

Speaker:

and say, Hey, we are seeing ransomware traffic coming out of your network.

Speaker:

You need to

Speaker:

Hmm.

Speaker:

Just a heads up.

Speaker:

Well, and that's, that's pretty common.

Speaker:

Uh, the majority of.

Speaker:

The majority of notifications to the help desk about something weird going wrong,

Speaker:

going on is usually made by a third party.

Speaker:

It's just the way it's, uh, we're so focused on operations, uh, and, and

Speaker:

keeping the lights on and the fires out.

Speaker:

very rarely do we see these weird things.

Speaker:

And so those, those third parties, whether it's law enforcement or an ISAC or a

Speaker:

customer or somebody working from home, it's usually somebody else notifying

Speaker:

us that weird things are happening.

Speaker:

And so as ransomware progresses, uh, and there's different, and we

Speaker:

touched on this initially too, there's different types of ransomware attacks.

Speaker:

There's the type that attacks just you as a user.

Speaker:

Whether you're, you know, grandma at home or you're just working from home and

Speaker:

you've got this, this hybrid workstation where it's business and some personal

Speaker:

stuff, uh, or just business, but.

Speaker:

We're working from home as kind of as an individual, and so we get infected

Speaker:

outside of the, the normal organizational network, the corporate network.

Speaker:

We're, we're working off of a wifi at the library or a coffee shop or

Speaker:

at home, and so we don't have the same network perimeter protections

Speaker:

that we might have at, at, at work.

Speaker:

Well, those, those attacks focus primarily just on this laptop, this endpoint.

Speaker:

And it's, it's kind of a one dimensional attack.

Speaker:

You're not connected to anything else.

Speaker:

It's just gonna do what it does here, and there's something valuable that

Speaker:

you're willing to pay a ransom for.

Speaker:

Well, then the, the attacks at work on the corporate network, the organizational

Speaker:

network, are a bit different in that the bad guys want to do enough

Speaker:

reconnaissance first to see what they have access to, and then make that,

Speaker:

that ransomware, that infection as broad as possible all at the same time.

Speaker:

So in most cases, they will compromise an account, try to es elevate to a, an admin,

Speaker:

uh, or equivalent account power user.

Speaker:

find your domain controllers and then script a deployment package to put

Speaker:

malware on all your computers, all your endpoints, all at the same time

Speaker:

with a trigger to start infecting and encrypting all at the same time.

Speaker:

And so we had, we had one, uh, it was a, it was a pretty large company,

Speaker:

uh, headquartered in Dallas that has projects all over the country.

Speaker:

dollar projects, multimillion dollar projects.

Speaker:

And, um, they infected 2,800 machines all at the same time, within four hours.

Speaker:

Hmm.

Speaker:

So Friday morning, I

Speaker:

Wow.

Speaker:

think it kicked off at 4:00 AM And so by the time people

Speaker:

came to the corporate office.

Speaker:

machine, 80% of their environment was encrypted in four hours.

Speaker:

And they didn't notice anything before that the 2,800 machines were encrypted.

Speaker:

And even though this is a pretty large environment, they only

Speaker:

had three or four full-time.

Speaker:

IT staff, had a, an executive it.

Speaker:

I'm not sure if he was the CIO or director of what his title was.

Speaker:

Uh, but in this particular case, and then, you know, kind of working backwards, you,

Speaker:

you get the phone call, we need help, you show up, assess the current situation, and

Speaker:

you work backwards to how did this happen?

Speaker:

And we're, so we're starting to piece together, you know,

Speaker:

that was the domain controller.

Speaker:

You know, there was a script, there was all this stuff.

Speaker:

Well, how did they get to the domain controller?

Speaker:

Will they use this account?

Speaker:

Well, how'd they get that account?

Speaker:

And so you're working backwards to patient zero.

Speaker:

And it was actually the, uh, the backup administrator.

Speaker:

Uh, who,

Speaker:

backup Bob.

Speaker:

who, who had worked at this company forever and never taken a vacation

Speaker:

some three or four months ago, uh, while he was looking for vacation

Speaker:

stuff, got infected and they had

Speaker:

Hmm.

Speaker:

to his account for months while also watching him plan his vacation, which

Speaker:

then they lined up their attack with, so he left for vacation Wednesday night.

Speaker:

They, they conducted this attack, uh, Friday morning, and so we actually

Speaker:

were considering him as a suspect as part of this, uh, ransomware.

Speaker:

Right.

Speaker:

we started seeing, uh, several years ago threat actors have been propositioning

Speaker:

internal privileged users to help them their ransomware in exchange for a,

Speaker:

a percentage of the, the monies paid.

Speaker:

But in this

Speaker:

Yeah.

Speaker:

case, they, they had access through a, a network vulnerability,

Speaker:

um, several months prior.

Speaker:

Um, that, uh, um, additional access through the backup administrator account.

Speaker:

And then in this case, the business decided to pay the ransom because

Speaker:

they, these large multimillion dollar projects were at stake and they

Speaker:

wanted to make sure that they got their data back and could continue.

Speaker:

Uh, working on these things.

Speaker:

Uh, so they paid the ransom on a Monday and the very next day, the threat

Speaker:

actors, uh, messaged them back and said, you know, for another $80,000,

Speaker:

we promised to leave you alone.

Speaker:

And it was because they had, they had, you know, I talked about persistence.

Speaker:

Well, they knew that we were gonna clean all the ransomware off, but they

Speaker:

had also configured, um, two dormant back doors that would've allowed

Speaker:

them to regain access to the network.

Speaker:

At a future date.

Speaker:

Well, we had found those over the weekend and made sure everything

Speaker:

was, was clean and tight.

Speaker:

Um, no, no ability to get back in.

Speaker:

So we told them, you know, we told them not to pay the ransom

Speaker:

to begin with, but did it anyway.

Speaker:

And then the, the next day when they said, you know, you pay some more money, we,

Speaker:

we, we will promise to leave you alone.

Speaker:

We told them that we took care of all that and they didn't need to do it.

Speaker:

So.

Speaker:

So a, a question that I have, uh, Mike, is with all of these things,

Speaker:

especially during this reconnaissance phase, surely a good SEIM tool

Speaker:

Mm-Hmm.

Speaker:

see this stuff going on.

Speaker:

Right, and, and can detect it.

Speaker:

Surely that's the case.

Speaker:

Tell me, I'm, and I know that nobody installs them.

Speaker:

Right.

Speaker:

I understand that.

Speaker:

Like, it, it's a, it's an expense for that, that a lot

Speaker:

of companies don't install them and that, and it doesn't matter.

Speaker:

But my question is, what's that?

Speaker:

Or configure them properly.

Speaker:

Right?

Speaker:

Or they've configured 'em because they got too many false positives

Speaker:

and they've, they've ified it right.

Speaker:

You, you're, you're right.

Speaker:

Uh, and, but I think there's a misconception there, uh, that,

Speaker:

that these tools are too expensive.

Speaker:

They, they used to be very expensive.

Speaker:

And really it's, it's the labor that's the most expensive part.

Speaker:

And that's why working with a managed security service provider

Speaker:

is a much better approach.

Speaker:

you're not paying one for one labor, you're, you're paying a,

Speaker:

a disproportionate amount of, of labor because their labor is

Speaker:

spread across all their clients.

Speaker:

And so, SEIM products back in the day for sure, uh, and there were open, they're

Speaker:

still open source SEIM products, but, uh.

Speaker:

to, to you guys' point you, you've gotta configure those, uh, well then

Speaker:

if, if you're not in the, the sim, if you're not experienced in, in how

Speaker:

to configure a sim, then you could be missing the, the, the point there too.

Speaker:

You could be missing a lot.

Speaker:

So, back to the experience and expertise of an MSSP, uh, to do all that for you.

Speaker:

So I think there's a misconception about price.

Speaker:

Uh, I, it's very affordable.

Speaker:

today than more affordable than it have ever has been.

Speaker:

And whether the client wants to own the license or or not,

Speaker:

that's a different conversation.

Speaker:

But to your point, yes.

Speaker:

new next gen security incident and event management tools, sims, um, are

Speaker:

capable of identifying weird stuff.

Speaker:

Uh, and so our sim, as an example, does use, it's UEBA user

Speaker:

and event behavior analytics.

Speaker:

it uses machine learning to develop a behavioral baseline

Speaker:

by user, by asset, by network,

Speaker:

And so for example, if Curtis does something 10 times a day, or his machine

Speaker:

does, and tomorrow it does 10 or a thousand, get flagged as the behavioral

Speaker:

anomaly before whatever that activity is evolves into a security incident.

Speaker:

So if you got ransomware.

Speaker:

That new file or even a file that maybe it, it, it looks like it's, uh,

Speaker:

something that's been ed on your machine forever, but it starts doing something

Speaker:

that your machine isn't normally doing.

Speaker:

get, we'll see a flag for that and.

Speaker:

In our experience, we'll also be able to determine, well, is that behavior

Speaker:

consistent with symptoms of ransomware or, or some other type of malware?

Speaker:

and then we can get on the phone and talk about, well, what did

Speaker:

you just do or what have you done?

Speaker:

On that note too, uh, I mentioned how organizations are typically, how

Speaker:

they identify ransomware or malware.

Speaker:

One of them is.

Speaker:

You get a call at the help desk today that a user says, Hey, about two weeks

Speaker:

ago, I, it, it just kind of occurred to me, it's really been bothering me, but

Speaker:

about two weeks ago I did this thing and you know, it's really been bothering me.

Speaker:

So I just thought I'd tell you now.

Speaker:

happens quite a bit too.

Speaker:

And so when you start looking at that user's machine and, and their,

Speaker:

their email and yep, sure enough you clicked on ransomware and it's

Speaker:

somewhere in this environment now.

Speaker:

So now we gotta go track it down.

Speaker:

Uh.

Speaker:

Yeah, there's any number of things and a SEIM tool too, you can populate

Speaker:

with, for example, if, if, if Mike got ransomware and we can determine the

Speaker:

type of ransomware it is, we can then go do research on the, the, the, at

Speaker:

the characteristics of that ransomware.

Speaker:

I can now put that in the SEIM tool and it can look across your entire

Speaker:

environment for other, um, other occurrences of those things during, to

Speaker:

try and get ahead of the next infection.

Speaker:

Um.

Speaker:

But really SEIM is just part of the solution.

Speaker:

You've also have, you also have to have a good protection, anti-malware,

Speaker:

and those two things need to play well together the SEIM can identify the weird

Speaker:

stuff, but then it has to be capable of telling the anti-malware on the, the,

Speaker:

the computer what to quarantine and clean and, and do all this automatically

Speaker:

because I've been preaching this forever.

Speaker:

Response is the most important thing.

Speaker:

You're gonna get attacked, you're gonna get infected, it's gonna happen.

Speaker:

The only thing that's gonna save you, or at least mitigate the impact is how fast

Speaker:

you can identify it and respond to it.

Speaker:

Is

Speaker:

so

Speaker:

Is it.

Speaker:

making sure that your tech stack really plays well together so that your response

Speaker:

is, is as effective as it can be.

Speaker:

Is it too soon to bring up the C company, the company whose name starts with the C?

Speaker:

CrowdStrike.

Speaker:

Yeah.

Speaker:

It is not,

Speaker:

too soon.

Speaker:

it's not

Speaker:

I, I, well, I will say, well, we don't have, we don't have much

Speaker:

time left, but uh, if we can cover them quickly, I suppose.

Speaker:

so CrowdStrike's a great, uh, endpoint protection tool and it, it has some

Speaker:

really good capabilities as far as interacting with Sims as an example

Speaker:

where the SEIM says weird stuff.

Speaker:

Hey, CrowdStrike, go do this thing, clean that, that, uh, that machine.

Speaker:

But I think it's also an interesting time to add that those endpoint, uh, that, that

Speaker:

anti-malware stuff, that, that system, that, that software that's running on

Speaker:

your system, it's collecting all this contextual data that's then feeding up to

Speaker:

a SEIM and it's, it's the ability of that.

Speaker:

That software on the endpoint, that CrowdStrike as an example.

Speaker:

It's the, it's the, it's the ability of CrowdStrike to collect this good

Speaker:

contextual data then gonna allow the SEIM to, to build a good baseline

Speaker:

and, and really quickly determine where the deviations from normal are.

Speaker:

in a lot of cases, the sim.

Speaker:

Is gonna detect that behavioral anoma anomaly before CrowdStrike will,

Speaker:

because CrowdStrike is still kind of, is very rules based when this

Speaker:

and this and this and this happened.

Speaker:

That's a security problem.

Speaker:

CrowdStrike does really good at addressing security problems.

Speaker:

CrowdStrike does not currently do really good at saying, Hey, that's never

Speaker:

happened before, or That's happened a heck of a lot more often than it used to.

Speaker:

That's what the SEIM does.

Speaker:

But then the SEIM and the, and and CrowdStrike, as in this case,

Speaker:

have to play really well together.

Speaker:

So when the SEIM says That's weird, Hey, CrowdStrike.

Speaker:

Put a pause on that, put a pin in that, put it, put it in

Speaker:

quarantine, put it in timeout until we figure out what's going on.

Speaker:

And we see that a lot in, um, organizations, especially it

Speaker:

where we're rolling out updates.

Speaker:

We're installing new software or third party things like your

Speaker:

financial system or your dealer management software needs to update

Speaker:

something that the SEIM is gonna go.

Speaker:

No.

Speaker:

Oh, that's weird.

Speaker:

And you're gonna hear it from it or, or the end user going, Hey, my, my install

Speaker:

paused, or it didn't work, or whatever.

Speaker:

And Well, that's good.

Speaker:

It's, it's working the way it should.

Speaker:

Yeah.

Speaker:

Yep.

Speaker:

Yeah, it would've, it would've been nice if, if a, if a SEIM tool had

Speaker:

said, Hey, uh, uh, that file you just pushed out is zero length.

Speaker:

Uh, you might might wanna take a look at that.

Speaker:

right.

Speaker:

And so, well that's a whole other story and a whole other ball of wax.

Speaker:

But that's right.

Speaker:

yeah.

Speaker:

um.

Speaker:

In this case, it was an involuntary patch.

Speaker:

You, you didn't have a choice of, of not

Speaker:

Yeah.

Speaker:

installing

Speaker:

Yeah,

Speaker:

it, it, it messed things up.

Speaker:

But if you had a good incident response plan with a playbook that says when

Speaker:

these certain types of things happen, and they can be categoric things

Speaker:

like, my machine stopped working.

Speaker:

I've got this blue screen of death.

Speaker:

I don't know what to do with it.

Speaker:

Uh, well, there's a playbook for that

Speaker:

Throwing

Speaker:

we.

Speaker:

so, so if you're not.

Speaker:

and,

Speaker:

So if you're,

Speaker:

to call and, and here's where the, the extra machines are or the images

Speaker:

that we need to re, re-image machines with or whatever the case was.

Speaker:

We've thought through this and here's our playbook for it.

Speaker:

And that needs to be part of your incident response plan.

Speaker:

so basically not Delta Airlines apparently.

Speaker:

Yep.

Speaker:

Oh.

Speaker:

Uh,

Speaker:

But

Speaker:

anyway.

Speaker:

By, by the way, it's funny.

Speaker:

Yeah.

Speaker:

What was that?

Speaker:

credit, having a good virtual environment with your snapshots

Speaker:

and all those things that

Speaker:

Yeah,

Speaker:

that saved the other airlines,

Speaker:

yeah,

Speaker:

or, or in some cases, some of the airlines had different operating

Speaker:

system environments and all that too.

Speaker:

But the, the virtual

Speaker:

yeah.

Speaker:

able to, to, uh,

Speaker:

It was just,

Speaker:

snapshots

Speaker:

it was funny, I, I, last week I flew to Atlanta for, you know, the company that

Speaker:

I worked for and for the first time.

Speaker:

No one asked me, why didn't you fly Delta?

Speaker:

Well at.

Speaker:

Oh.

Speaker:

Anyway, well, well listen, we gotta finish up here.

Speaker:

Um, so what I'm, what I'm hearing from you is it does sound like a, a good SEIM

Speaker:

tool is, um, SEIM tool versus XDR tool.

Speaker:

Uh, just a quick thought there.

Speaker:

Um, you know, 'cause I know there's both.

Speaker:

so, SEIM is a little limited in, in its traditional ability.

Speaker:

It's a, it's traditional ability to ingest data.

Speaker:

So, uh, in SEIM tools typically don't have that automated response.

Speaker:

They call it soar.

Speaker:

The, the, the orchestration of automated response.

Speaker:

So SEIM tools, that's usually a bolt-on a third party or, or extra.

Speaker:

But SEIM also does just tra traditional SIS log and.

Speaker:

firewall log, you know, that kind of thing.

Speaker:

Open XDR or XDR, uh, XDR is better because it's, it's primarily,

Speaker:

it's, it's more of an open source approach, but XDR is that extra.

Speaker:

Well, now I can adjust, uh, cloud and third party tools and I OT devices and OT

Speaker:

device scada, uh, you know, smart stuff.

Speaker:

Um, so it's, it's the evolution of sim, um, not just in its ability,

Speaker:

but it's also, its its scope.

Speaker:

Uh, so in in cyber uh, ingestion, we talk about north,

Speaker:

south, east, and west traffic.

Speaker:

So North and south is in and out of your environment, and east and

Speaker:

west is, is within your environment.

Speaker:

And as we, as, as a lot of environments start to migrate, either, either totally

Speaker:

to the cloud or some hybrid on-premise cloud architecture, it's really

Speaker:

important to to, to have a, a platform that's capable of, of expanding with

Speaker:

you, uh, both in scope and capability.

Speaker:

And, uh, so our platform is actually an open XDR platform.

Speaker:

Um, it connects to just about anything that has a data, uh, a data feed.

Speaker:

Cool.

Speaker:

All right.

Speaker:

Well thank you again, um, Mike, for joining us.

Speaker:

As always, anytime happy to be here

Speaker:

Persona, I, I am still glad to see you alive and not decapitated or

Speaker:

or

Speaker:

any, um,

Speaker:

you were gonna make fun of me too.

Speaker:

I know that you were like, ah, excuses, excuses.

Speaker:

because again, normally this is me, not you that's doing the stupid stuff.

Speaker:

Um, why am I seeing the outlet box for my thing at least?

Speaker:

Did you, did you install this fan?

Speaker:

Nope.

Speaker:

Okay, well then, well you guys, because that would be me.

Speaker:

Yeah.

Speaker:

the one who installed the fan improperly 20 years ago, and

Speaker:

then the fan is coming down.

Speaker:

Um, and as I look at the air conditioner that I've installed up over there.

Speaker:

Um, all right, well, thanks again to our listeners.

Speaker:

We would be nothing without you.
