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.
Speaker:Uh, that is a wrap.
