Welcome to the backup wrap up.
Speaker:The only podcast dedicated to the underappreciated heroes of
Speaker:the data center backup admins.
Speaker:We're continuing our coverage of ransomware, and today we're
Speaker:again talking about preventing it.
Speaker:We'll cover a range of preventative measures including application
Speaker:whitelisting and blacklisting, inventorying service accounts, restricting
Speaker:risky services, and the importance of establishing relationships now with red
Speaker:and blue teams as well as law enforcement.
Speaker:Let's keep ransomware out of your environment.
Speaker:By the way, if you don't know who I am, I'm w Curtis Preston, AKA, Mr.
Speaker:Backup, and I've been passionate about backup and recovery for over 30 years.
Speaker:Ever since.
Speaker:I had to tell my boss that there were no backups of the
Speaker:database that we had just lost.
Speaker:I don't want that to happen to me ever again.
Speaker:I don't want it to happen to you.
Speaker:That's why I do this podcast.
Speaker:Here we turn Unappreciated backup admins into Cyber Recovery Heroes.
Speaker:This is the backup wrap up.
Speaker:Welcome to the show.
Speaker:Before we get started, I just want to ask you to press the follow or subscribe
Speaker:button so that you can always get this show, whether you're following
Speaker:on an audio format or on YouTube.
Speaker:Uh, either way we'd love to have you.
Speaker:I'm your host, w Curtis Preston, AKA, Mr.
Speaker:Backup, and with me, I have my.
Speaker:Non-standard air conditioning installer, sympathizer Prasanna Malaiyandi.
Speaker:How's it going?
Speaker:Prasanna?
Speaker:I am doing well, Curtis, and here's a question.
Speaker:Do you have working air conditioning as of this moment?
Speaker:No,
Speaker:I do have, it's, it's at 95%.
Speaker:Um, I'm doing a very non-standard.
Speaker:I'm installing.
Speaker:One of those portable air conditioners, but I'm installing it up on the wall so
Speaker:that, because where I live, you know, I have an HOA and they won't let me
Speaker:put like a window unit air conditioner.
Speaker:Right.
Speaker:So I have the, you know, but I don't, I don't have a spot to put it on the
Speaker:floor, so I'm mounting it up on the wall.
Speaker:So it involves lots of heavy.
Speaker:Brackets and things like that, and lots of, uh, literal sweat
Speaker:equity and putting it up.
Speaker:And sadly I put it up and then, as you know, uh, had to take it down and
Speaker:put it up again because I neglected to account for the distance between the
Speaker:exhaust port and the window oopsies.
Speaker:Yeah, that's not good.
Speaker:Oopsie.
Speaker:Do you, did you also cut a hole for the cord?
Speaker:I did, I cut a hole for the,
Speaker:Okay.
Speaker:I cut a and, and I cut a very nice hole, a very nice hole for the cord.
Speaker:That was the, another mistake in the first version.
Speaker:Uh, it's what happens when you're just sort of winging it, you know?
Speaker:Like, oh, I just need a shelf.
Speaker:I just need a shelf.
Speaker:And some brackets, I bought some nice brackets, you know?
Speaker:might I recommend,
Speaker:Yeah.
Speaker:I know it's like above like a bed and things like that, that
Speaker:sometimes people sleep in.
Speaker:Yeah.
Speaker:I recommend telling people whenever they sleep to put their head on the
Speaker:other side away from the AC unit?
Speaker:Well, they can sit up.
Speaker:No, no, no.
Speaker:I'm
Speaker:What
Speaker:in case something falls.
Speaker:are you questioning?
Speaker:The structural integrity of my air conditioning unit.
Speaker:no, but just say that there we live in California.
Speaker:There might be an earthquake, it might be enough that it shakes off even
Speaker:though you do have a lip to keep it in
Speaker:Yeah.
Speaker:I.
Speaker:Yeah, I do have a lip to keep it in place.
Speaker:saying that having a 65 pound or whatever air conditioner fall on your head is
Speaker:probably a lot worse than a 65 pound air conditioner falling on your foot.
Speaker:Uh, yeah, that's probably true.
Speaker:That's probably true.
Speaker:So, uh, but thanks for that image.
Speaker:Um.
Speaker:So we're gonna continue our series in ransomware.
Speaker:Uh, this one is gonna be talking about ransomware prevention.
Speaker:In terms of other things that we can do, we've already talked about,
Speaker:um, the, you know, we've talked about protecting the backup server.
Speaker:We've talked about the, the three things that everyone
Speaker:should do to prevent ransomware.
Speaker:What are those three things?
Speaker:Prasanna?
Speaker:Patch
Speaker:Yeah.
Speaker:Patch management.
Speaker:password
Speaker:Password management.
Speaker:M-F-A-P-P-M.
Speaker:if you're not using, um.
Speaker:If you're not using MFA at this point, uh, you're gonna hear, it's
Speaker:gonna come up again in this episode, but this is in addition to that.
Speaker:In addition to all the stuff that you did to, to, you know,
Speaker:this is assuming you did that.
Speaker:What's the next step?
Speaker:These are the, please do these things.
Speaker:Um, it will also make it harder for you to be attacked by
Speaker:ransomware and the, the first one.
Speaker:could make it harder for you to also use things too.
Speaker:What
Speaker:It's
Speaker:this, this is true, right?
Speaker:A lot of times security is at war with usability,
Speaker:Yep.
Speaker:right?
Speaker:Um, and I, I tell the following, uh, story, which I know I've told here
Speaker:before, but I remember back when I first.
Speaker:Um, you know, did backup software.
Speaker:We used this lovely thing called RSH.
Speaker:Right.
Speaker:And all you had to have was, uh, you know, an entry in, uh,
Speaker:I forgot the name of the file.
Speaker:There was a file in the, the, you know, the, your, your, your home directory,
Speaker:which even if it was root you, if you had that file, um, and, and it had
Speaker:the name of the host you were coming from in that file, you could RSH.
Speaker:As root without a password.
Speaker:And, and I happen to know that one company where I, um, installed backup software.
Speaker:One of the many that I did throughout the years, household name company.
Speaker:Um, when I got there, they had RSH as root from every Unix
Speaker:host to every other Unix host.
Speaker:And this was like a major company.
Speaker:yeah.
Speaker:Um, why, why do I bring that up?
Speaker:Um, it, it, you know, I, I just remember how much the security people hated that.
Speaker:Right?
Speaker:Yeah,
Speaker:And, but, but lemme just finish.
Speaker:But the reason was that the tool in question was our dump.
Speaker:Our dump wouldn't work if you didn't, if you couldn't RSH
Speaker:as root without a password.
Speaker:Yeah.
Speaker:Okay, so that's one side.
Speaker:Now let's go to the other extreme, right where I think you've told a
Speaker:story on the podcast before the one company you worked at where the network
Speaker:people locked down every single server.
Speaker:yeah, yeah.
Speaker:It was the most secure company that I'd ever worked at.
Speaker:It was the complete opposite of that other company and, um,
Speaker:where we, we were prepping for Y 2K and that they were really.
Speaker:It was, it was a very secure environment where they did, they did all the
Speaker:things that we asked people to do and, and you weren't able to get
Speaker:from one server to another server.
Speaker:It's like, the question was, why do you need to get from server A to server B?
Speaker:Right?
Speaker:Uh, you, you needed a reason to be able to communicate between those
Speaker:two servers and then they would open up only the port that you needed.
Speaker:And I was the, the one crazy guy that, you know, my server needed
Speaker:to talk to all the servers because.
Speaker:Backup.
Speaker:And they didn't like that, and they kept trying to shut it down.
Speaker:And then, and, and then they, and then they kept trying
Speaker:to like sniff the problem.
Speaker:The problem with net backup, uh, well, one of the problems with net backup is
Speaker:that it uses a random series of ports.
Speaker:And, um, so they did not like that and they kept shutting things down.
Speaker:And Yes, uh, it, it just, it was, uh, so let's just say this.
Speaker:This thing of security, being at war with usability is not, it's not a new problem.
Speaker:Yep.
Speaker:Um, and the first thing that I want to talk about it, it's just something that
Speaker:I want you to think about because as I recall the last time you and I talked
Speaker:about it, I think you were against it.
Speaker:Um.
Speaker:And, and, and we'll, we'll see.
Speaker:Um,
Speaker:yeah.
Speaker:that is this concept of application white listing.
Speaker:Uh, and in my notes, I have this as the silver bullet.
Speaker:And why do I say that?
Speaker:And we can argue as to whether or not it's a good silver bullet.
Speaker:But why do I say it's a silver bullet,
Speaker:Because you're basically restricting what runs in the environment.
Speaker:right?
Speaker:I.
Speaker:you control what runs, then there's less likelihood that you will be
Speaker:using something that is malicious.
Speaker:Right, right.
Speaker:So if we, if we say only, you know, Microsoft Word and SQL Server and
Speaker:SharePoint are the only things that are allowed to run on this box.
Speaker:If there's something other than that malware based, then it just
Speaker:won't be able to run because it's not whitelisted, right?
Speaker:Yeah.
Speaker:It is a giant pain in the butt.
Speaker:Geez.
Speaker:Can, can we agree that application white listing is a giant pain in the butt?
Speaker:What do you think?
Speaker:Yeah.
Speaker:No, I agree.
Speaker:Yeah.
Speaker:Is it however, something that we should think about in certain circumstances?
Speaker:For example, if you have a very well, uh, understood.
Speaker:End user community, that they all use the same 17 applications.
Speaker:Right?
Speaker:Yeah.
Speaker:And you could, you could lock it down to the same 17 applications for all of those.
Speaker:And then of course you will absolutely have some users who are special.
Speaker:Their name will probably be Curtis or Prasanna.
Speaker:'cause we always want to do stuff that's outside of the norm.
Speaker:Right.
Speaker:Um.
Speaker:You, you, you'll have a handful of power users that will end
Speaker:up with 37 other applications.
Speaker:I, I think that in those scenario, like we don't, maybe we don't have to
Speaker:do it for, well, there, there's just, there are areas where maybe it's harder
Speaker:to do than others and I'm thinking
Speaker:or functional units.
Speaker:Right, right.
Speaker:Yeah,
Speaker:Um, if there's an area where you can do this, I guess I'm
Speaker:just saying think about it.
Speaker:yeah.
Speaker:If you application white listing, I think it would be, it would go a long
Speaker:way to stopping ransomware or any
Speaker:I think there's different ways you can implement application whitelisting,
Speaker:One way is to sort of say, Hey, here is a list of approved IT applications
Speaker:that you are allowed to install and deploy, but don't necessarily prevent
Speaker:people from installing other things.
Speaker:You sort of use the honor system or IT policies just like everyone has, right?
Speaker:You sign a code of conduct when you join a
Speaker:right.
Speaker:right?
Speaker:Or the employee handbook, right?
Speaker:and then could we perhaps monitor for anything that is outside
Speaker:the white list and then send off the, the CLS and alerts when it
Speaker:Yep.
Speaker:Yeah.
Speaker:Yeah.
Speaker:Right.
Speaker:So you can at least start a process so you're not getting in the
Speaker:way, but at least you're having an ability to monitor and figure
Speaker:out, okay, what are people doing?
Speaker:Does this make sense?
Speaker:And maybe you also have a list of applications, because I think in
Speaker:addition to having a list of applications that you approve in that white list,
Speaker:it's also important to have a list of applications that you block.
Speaker:Yeah.
Speaker:Which is also as equally as important,
Speaker:what would, what would the name of that process be?
Speaker:Application blacklist.
Speaker:Yes.
Speaker:Okay.
Speaker:You, you said that like, it, you weren't sure.
Speaker:Yes.
Speaker:It's the opposite of a white list, right?
Speaker:Application blacklist.
Speaker:Right.
Speaker:So you could, you could have a, a series of apps.
Speaker:Um, and, and I would put a lot of the security software that is
Speaker:often installed by, um, uh, cyber attackers as, um, bl blacklisted.
Speaker:Again, there are exceptions to the blacklist where you need to install
Speaker:it, and then you want to find out who, who is actually trying to
Speaker:install such, such tools, right?
Speaker:Um.
Speaker:And I think another thing Curtis, that becomes interesting is days a lot
Speaker:of people just use SaaS application.
Speaker:So by using a SaaS application, you don't even have to worry about
Speaker:application whitelisting as much anymore.
Speaker:Isn't SaaS so great?
Speaker:There are things I don't like, as, you know, there are things I
Speaker:don't like about the SaaS world.
Speaker:I'm concern very much about all the data that's out there, but, um, but this is
Speaker:definitely a, an advantage of the SaaS.
Speaker:Uh, you know, we're, I mean, as we are talking, we are using a SaaS application.
Speaker:Mm-Hmm.
Speaker:I don't know how we would do this back in the day.
Speaker:Right.
Speaker:I guess we could, what, what was that tool that we used to O-B-O-B-C-O-B-S-O-B-S.
Speaker:We, we used to use OBS, um, and theoretically we could do that, but we
Speaker:would still need a way to see each other.
Speaker:Um, which,
Speaker:have FaceTime running in parallel.
Speaker:would be a SaaS.
Speaker:Yeah,
Speaker:Yeah.
Speaker:There.
Speaker:You know what I remember back in the very early days, I remember
Speaker:software that you used on your laptop.
Speaker:You had a piece of software running on your laptop.
Speaker:They had a piece of software running on their laptop, and those two pieces
Speaker:of software directly communicated, um, to, to webcam to each other.
Speaker:Man, those were such, so, so bad in terms of quality.
Speaker:Yeah.
Speaker:Oh yeah.
Speaker:So yeah, that the, the SaaS world makes things a lot easier.
Speaker:Um.
Speaker:All right, so enough of that.
Speaker:So now let's talk about disabling other attack vectors.
Speaker:Now, one of the things that came up when, um, we had Dwayne on with the, the, the
Speaker:red team, uh, episode, which at this point is now about five or six episodes back.
Speaker:Is this idea that there are service accounts out there that are running
Speaker:with like, no, no password default passwords are really crappy passwords.
Speaker:Right?
Speaker:What's a, what's a service account?
Speaker:Why does this matter?
Speaker:So a service account is like a special privileged account that runs on the system
Speaker:and is used for things that need to happen without necessarily user interaction.
Speaker:an example, backup.
Speaker:Right.
Speaker:So normally you have a backup service account that runs on
Speaker:the system and kicks off backups that need to happen on the system
Speaker:Do you remember the special thing he said about the backup service account?
Speaker:that it had access to everything.
Speaker:It had a access to everything without logging,
Speaker:Yeah.
Speaker:right.
Speaker:Oh, that's right.
Speaker:Right,
Speaker:Yeah.
Speaker:so it can access all the files that it wants, download all the files it wants,
Speaker:because that's what backup is, right?
Speaker:Override all the files it wants, because that's what Restore is without
Speaker:triggering any alarms of any kind.
Speaker:Yeah,
Speaker:here you have it installed with the password of backup
Speaker:or, or maybe it's installed with net backup or networker or TSM.
Speaker:Um.
Speaker:Yeah.
Speaker:Or Veeam, right?
Speaker:Uh, please, please don't do that.
Speaker:Right?
Speaker:So, so I wanna talk about, so we need to figure out how many
Speaker:service accounts are out there.
Speaker:And so there is this, uh, there is this concept of a service account inventory.
Speaker:Um, and when I, when I googled that there, you know, there, there, there were
Speaker:some, uh, some things that you could do.
Speaker:Obviously they talked about things like reviewing the documentation, uh, you know,
Speaker:any documentation you have as to where you would typically install service accounts.
Speaker:Uh, there are active directory tools such as, uh, you know, PowerShell
Speaker:that you can look for, things like.
Speaker:Special account flags and two special account flags pop up.
Speaker:Do you know what they are?
Speaker:I'm gonna guess no.
Speaker:Why would you know this?
Speaker:Right?
Speaker:The two special account flags that they popped up are, don't expire.
Speaker:Password or password?
Speaker:Not required.
Speaker:Ugh.
Speaker:Password not required.
Speaker:Um, you know, look for group membership, like domain admins, enterprise admins,
Speaker:um, you know, and look for the types of applications that need service accounts.
Speaker:What kinds of applications besides backup would you think those are?
Speaker:Right,
Speaker:Anything that runs as like a Damon process right in the background on the system,
Speaker:right.
Speaker:Um.
Speaker:security software
Speaker:Right.
Speaker:Security software, ironically enough, u uses a service account antivirus.
Speaker:Right.
Speaker:Um, the, um, go ahead.
Speaker:But I think though a service account, you cannot, normally, you're not allowed
Speaker:to log in using a service account,
Speaker:Right.
Speaker:right.
Speaker:It is just for things that are already on the system to be able to operate
Speaker:with different privileges on the system.
Speaker:Yeah.
Speaker:Right.
Speaker:You can't log in like in the traditional sense, but you can log in from an
Speaker:API perspective and do the things that that thing is supposed to do.
Speaker:And so all I'm saying is figure out what those are and give them real passwords.
Speaker:If you've got accounts, service accounts that say, don't, you know, no password
Speaker:required, it seems like that is bad.
Speaker:Yeah, and I think the other thing to mention is the service accounts are
Speaker:basically on a per machine basis.
Speaker:Yes.
Speaker:So it's not like you can go look in active directory and say, Hey, where,
Speaker:what are all my service accounts?
Speaker:You have to hit every single box and say, what are the service accounts available?
Speaker:And that's why you use things like PowerShell and other things
Speaker:make sure, okay, what is there?
Speaker:And this inventory shouldn't be on a one-time basis either
Speaker:Right.
Speaker:applications get added.
Speaker:Remove systems come online, get decommissioned.
Speaker:Yeah, a very regular thing.
Speaker:You should be out there looking for new service accounts.
Speaker:So I'm hearing that the most common way that systems are compromised these
Speaker:days is, um, sole and credentials.
Speaker:What's the second?
Speaker:Most common way.
Speaker:What was that for those not watching the video version on YouTube?
Speaker:Uh, Prasanna just made a, a, I think that was, was that like a phishing reel?
Speaker:Uh,
Speaker:it's a phishing reel and then, uh, pull it back in
Speaker:um, yeah.
Speaker:phishing with a pH, uh, phishing and, uh, and spearphishing, which
Speaker:is a very specific type of phishing.
Speaker:The, and this is often via, um, email, right?
Speaker:And so another thing I'd like you to consider is, again,
Speaker:these are all optional things.
Speaker:Um, you know, some less optional I think than others.
Speaker:But this is something to consider and that is the idea of putting in some
Speaker:type of monitoring system, filtering system in your email system in
Speaker:order to, uh, see if you can catch.
Speaker:You know, use ai, um, and, and other tools to identify phishing,
Speaker:uh, attacks on the front end.
Speaker:and I believe that many of the SaaS email providers like Microsoft and
Speaker:Google have pretty extensive phishing protections already built in, but
Speaker:it doesn't mean you shouldn't use a third party solution as well.
Speaker:I think that's true everywhere, right?
Speaker:That there's often
Speaker:Yeah.
Speaker:os tools that are available, but there are, um.
Speaker:Uh, third party tools that may be more extensive.
Speaker:The question, they will also be more expensive,
Speaker:Yeah.
Speaker:Extensive and expensive.
Speaker:Um, all right, so we gotta talk about my favorite boogieman.
Speaker:What, what is it?
Speaker:Port 3 9, 2 2, I
Speaker:Is that.
Speaker:Or is it three?
Speaker:Five.
Speaker:Five, three.
Speaker:Is that the port for RDP, the Ransomware deployment Protocol?
Speaker:Um, yeah.
Speaker:I,
Speaker:Nine.
Speaker:what's that?
Speaker:3, 3, 8,
Speaker:3, 3, 8.
Speaker:get that tattooed on your forehead.
Speaker:Um, I'm, I'm suddenly, I'm thinking about, um, 2 4, 6 0 1 from, um, Les Mis,
Speaker:Yeah.
Speaker:so.
Speaker:Please shut off RDP at, at a bare minimum, restrict RDP, so that it,
Speaker:you know, so that the RDP port is only accessible via a particular network.
Speaker:And that network should only be accessible via A VPN, which
Speaker:is only accessible via MFA.
Speaker:We're gonna get back to that and, you know, restrict s and b as much as you can.
Speaker:Um, I'm sorry.
Speaker:Restrict RDP as much as you can.
Speaker:Uh, and then also, you know, I threw out SMB.
Speaker:Lemme just throw that out.
Speaker:Um, windows has a default administrative share.
Speaker:What's up with that?
Speaker:Right?
Speaker:it admin dollar?
Speaker:Yeah.
Speaker:Um, that's what it's, and, and, and you can access the entire, uh, c drive, right?
Speaker:Um, turn that sucker off.
Speaker:Why, why is it there?
Speaker:Um, you know, why is it there?
Speaker:Why is it on by default?
Speaker:I, you know, I, I'm sure you know if you've got, by the way, if
Speaker:you disagree with me, uh, feel free to do so in the comments.
Speaker:I would love to hear, uh, why the default administrative share.
Speaker:Is not just fundamentally evil like RDP, um, but this is an s and b share
Speaker:that is on by default in Windows server.
Speaker:Uh, and when Windows desktop
Speaker:Is it?
Speaker:Isn't it at Windows desktop though?
Speaker:Yes.
Speaker:'cause I've used it.
Speaker:Okay, because, so I was recently setting up my mom's new
Speaker:Mm-Hmm
Speaker:windows
Speaker:mm-Hmm.
Speaker:And when I went, because I was copying data over and I went to go
Speaker:access it another laptop, and it basically said sharing is disabled.
Speaker:Network sharing.
Speaker:That's a good question, right.
Speaker:Um, I'm not a Windows person.
Speaker:Uh, I.
Speaker:Neither am I.
Speaker:It took me a while and I wanted to pull out my hair,
Speaker:Yeah.
Speaker:But, um, the, um, you should tell your mom to upgrade to a real computer.
Speaker:Um,
Speaker:she likes her windows.
Speaker:Laptops.
Speaker:I'm not gonna argue with her.
Speaker:uh, yeah, uh, I know a lot of people like windows.
Speaker:I just, you know, I close windows whenever I can.
Speaker:Anyway.
Speaker:Um, so the next thing, uh, let's talk about, and I, I alluded to
Speaker:it already, and that is if your.
Speaker:Normal workday process requires A VPN.
Speaker:What do you think about having an MFA on that VPN?
Speaker:Oh, you definitely should.
Speaker:Yeah, this is
Speaker:but,
Speaker:of, of everything on this list.
Speaker:If you are allowing computers outside your company to access your company resources,
Speaker:and you're not using A VPN and you're not using MFA for that VPNI, you know, this.
Speaker:I, I don't know what to say.
Speaker:I have the question for you.
Speaker:Okay.
Speaker:Is it still technically considered MFA if you have an OTP in
Speaker:order to be able to log into
Speaker:I think, yeah, I think the, the OTP, um, you know, uh, I think
Speaker:that, well, assuming that OTP has, uh, MFA built into it, right?
Speaker:Um.
Speaker:it's like an RSA token, right?
Speaker:Yeah.
Speaker:Yeah.
Speaker:I mean, so I'm assuming, I, I'd assume that if you're using Okta or something
Speaker:like that, that you are going to enforce
Speaker:MFA.
Speaker:on your entire environment.
Speaker:If you do, I'm, I'm good.
Speaker:I'm just saying if you're remotely letting people access stuff inside
Speaker:your computing environment and you're not using MFA, uh, you know.
Speaker:Yeah.
Speaker:That's like you're asking for it kind of thing, right?
Speaker:Going back to what you previously said about credential stuffing
Speaker:Yes, exactly right.
Speaker:Why is that, by the way?
Speaker:What, what do you mean by that statement you just made?
Speaker:Because if you don't have MFA, then someone might compromise credentials
Speaker:somewhere else and say a user happens to reuse their passwords, they have access
Speaker:to your environment because they're able to connect via VPN without requiring MFA.
Speaker:There you go.
Speaker:But I wanna add one thing to
Speaker:Yeah.
Speaker:Even with MFA, train your users not to get hit by MFA fatigue.
Speaker:Yeah.
Speaker:Right.
Speaker:We've seen so many attacks where the attacker bombards the system
Speaker:with MFA requests and then the user's like, fine, fine.
Speaker:I give up.
Speaker:I don't know what's going on.
Speaker:Yeah.
Speaker:like, okay, it's me.
Speaker:Yeah.
Speaker:This, this goes back to the stuff that we talked about last week, about training
Speaker:the people that work in your environment.
Speaker:Right?
Speaker:Um, let them know what MFA, you know, an MFA fatigue attack is, and
Speaker:Yeah.
Speaker:to watch for it and to not, I.
Speaker:Respond to it the way that you just described.
Speaker:Yeah, yeah.
Speaker:Whatever.
Speaker:Just leave me alone, you know?
Speaker:Or
Speaker:that's what happened with the Okta attack,
Speaker:Yes.
Speaker:Yeah.
Speaker:many months ago.
Speaker:Yeah.
Speaker:Um, so here's another one that, that the link that you shared
Speaker:me, I think is fascinating.
Speaker:Um, the next thing I have on the list is reputable antivirus
Speaker:or anti-malware software.
Speaker:Uh, what, what did that article talk about?
Speaker:Yeah.
Speaker:So this was an article which happened to be published today.
Speaker:We're recording this.
Speaker:Um, and it was from the register, uh, and it basically said that.
Speaker:More than half the people.
Speaker:Even though antivirus tools are available on the operating system,
Speaker:Mm-Hmm.
Speaker:install third party antivirus solutions.
Speaker:Yeah.
Speaker:And one of the things that I found at the very bottom of this article,
Speaker:which I thought was interesting, they said malware writers, the first thing
Speaker:that they do is they'll probably go and test against the standard tools.
Speaker:Right.
Speaker:And by having a third party, you're now adding an additional layer of defense to
Speaker:protect you against being attacked and being, uh, infected by these malware.
Speaker:Yeah.
Speaker:You know, and those tools are, they're just like any of these tools.
Speaker:Nothing is.
Speaker:Um, what's that?
Speaker:Nothing is perfect,
Speaker:Yeah, nothing is perfect, but, um, you know, you know, maybe I'm an old
Speaker:schooler here and I, I believe in the concept of these third party tools.
Speaker:Um,
Speaker:another stat which I will call out, said that,
Speaker:oh,
Speaker:when they
Speaker:I don't like the stat.
Speaker:I don't.
Speaker:they looked at the statistics.
Speaker:They found that twice the number of people had third party software for if they
Speaker:were in the age group of 65 and above, versus in the age group of 45 and below.
Speaker:To that, I just wanna say bleep,
Speaker:uh, whatever.
Speaker:Um, all right.
Speaker:The, the final.
Speaker:But antivirus is important though,
Speaker:Antivirus is important.
Speaker:Yeah.
Speaker:Antivirus, anti-malware.
Speaker:Um, the, um, um, the next group of things that I want to talk about are, again,
Speaker:this isn't so much preventing, um, you know, preventing an attack as much as
Speaker:it is, you know, preparing for one.
Speaker:Well, no.
Speaker:Yeah.
Speaker:I guess this is.
Speaker:preventing,
Speaker:This is all also preventing, nevermind.
Speaker:yeah.
Speaker:The, the next group of things are, are a little bit different.
Speaker:And that is this idea of proactively going and doing things
Speaker:to see, to see what you can see.
Speaker:Right?
Speaker:Uh, and the first is this concept of an automated pen test.
Speaker:What is that?
Speaker:So a pen test is a penetration
Speaker:Mm-Hmm.
Speaker:where you can hire a company, you can procure software, where it will basically
Speaker:test your network, your systems, to see are there any common vulnerabilities?
Speaker:Are ports closed?
Speaker:Do you have RDP exposed to the internet?
Speaker:Things like that to help you understand, okay, where are
Speaker:the gaps in my systems today?
Speaker:Right.
Speaker:And, and they range, um, everywhere from like, uh, 29, 9, 9, you know, uh,
Speaker:we'll do a pen test of your company.
Speaker:And I don't mean to imply that there's no value there, but there's definitely less
Speaker:value there than the the, the next option.
Speaker:And that is this concept of a red team.
Speaker:Again, we had Dwayne Lalo on here from Pulsar Security.
Speaker:They are a red team, right?
Speaker:It's a fascinating episode, by the way, if you didn't, if you didn't
Speaker:Mm.
Speaker:take a look at that.
Speaker:Uh, it's about, I don't know, six weeks or so ago at this point, the
Speaker:idea that this is for those of you that have seen the movie sneakers,
Speaker:this is the guys in the movie sneakers.
Speaker:Those of you that haven't seen the movie sneakers, go watch the movie sneakers.
Speaker:it.
Speaker:It's.
Speaker:It ages actually pretty well.
Speaker:There's some stuff in there, just like any movie that centers around computers.
Speaker:There's some stuff in there that's complete bs, but, you know, um,
Speaker:You're not gonna recommend hackers or the net
Speaker:no, I'm not gonna recommend Hackers or the net or swordfish.
Speaker:Um, the net that, oh man, can't even.
Speaker:You remember it was about hitting the escape button.
Speaker:You remember how the escape button was like the
Speaker:uh, Sandra Bullock, right?
Speaker:Wasn't that Sandra Bullock?
Speaker:Yeah.
Speaker:Yeah.
Speaker:Um, interestingly enough that when you, when you, when you bring up those three
Speaker:movies, the only thing I remember, the pretty girls that were in those
Speaker:three movies, I don't, and the fact that the computer stuff was, was crap.
Speaker:Right?
Speaker:Um, anyway.
Speaker:Somehow I got distracted.
Speaker:What?
Speaker:Where were we talking about?
Speaker:red
Speaker:We were talking about red teams, right?
Speaker:So this is a professional team whose job it is to infiltrate
Speaker:your environment at your request.
Speaker:And this is hardcore stuff, right?
Speaker:Yeah, they're think like the hackers, right?
Speaker:They
Speaker:Yeah.
Speaker:almost ethical hackers if you think about it.
Speaker:Yeah.
Speaker:Yeah.
Speaker:Um, I remember Dwayne said that they kind of backed away from that
Speaker:term that they use, they use, um, I forgot what the term that they use
Speaker:instead, but basically Yeah, yeah.
Speaker:That, that there, there's like a more all inclusive term that
Speaker:they now use, but the, um.
Speaker:This is a company that you hire that is going to do all sorts of things to
Speaker:try to break into your environment.
Speaker:And, um, I, I remember one of his stories was about they hacked this
Speaker:company via a TV that was in the lobby.
Speaker:Right.
Speaker:And they did it by going and getting, they got, they figured out what the TV was.
Speaker:They figured out the brand of the tv.
Speaker:And then they went and got that TV and they tore it apart and then, you
Speaker:know, um, this is hardcore stuff.
Speaker:insecure wifi
Speaker:Yeah,
Speaker:in it that
Speaker:yeah, yeah.
Speaker:Um, and uh, this involves, this involves things like, uh, it could be phy, there's
Speaker:also physical, uh, penetration tests.
Speaker:Right.
Speaker:So, you know, I remember, um, uh, listening to Kevin Mitnick,
Speaker:which I know not everybody.
Speaker:Uh, liked or appreciates Kevin Mitnick, but, uh, I, I did learn
Speaker:a lot from his talk and it was, uh, this, it, it was about him.
Speaker:Um, basically, I.
Speaker:Going into a building.
Speaker:It was like a, it was like a commercial building and he went into the bathroom
Speaker:and he just waited into the bathroom for some other person to come and he
Speaker:used his badge scanner, which works up to like six feet away or something.
Speaker:And he's sitting in a.
Speaker:Bathroom skull waiting for some other kind of coat.
Speaker:And then he is scanning the guy's badge and then he uses that
Speaker:badge to get into the building.
Speaker:Right.
Speaker:This is the, you know, this is some, some, some hardcore stuff.
Speaker:It's like something outta Hollywood.
Speaker:Yeah.
Speaker:It is like something outta Hollywood, but the, you know, these are people that this
Speaker:is what they do and, um, they enjoy it.
Speaker:They're good at it.
Speaker:And you should definitely look into the concept of a red team.
Speaker:Now, what about a blue team?
Speaker:They're the ones who are trying to protect your environment
Speaker:Right?
Speaker:potential attackers.
Speaker:Right.
Speaker:And so.
Speaker:They're like the defense.
Speaker:Right.
Speaker:Yeah.
Speaker:They are the defense and they're also the ones that you would bring
Speaker:in when you have a cyber attack.
Speaker:Right?
Speaker:Yep.
Speaker:Um, and so one of the things that I talk a lot about is that
Speaker:you need to establish that.
Speaker:Um, and again, another one of the, another one of the experts that we've
Speaker:had on here that uh, is from a blue team is Mike Sailor from Black Swan
Speaker:Security, and we're gonna have, we're gonna have him on some more, and I.
Speaker:He, uh, he talks a lot about, he's been in many of these attacks
Speaker:and he completely agrees with me.
Speaker:Of course he does.
Speaker:'cause this is what he does.
Speaker:That now is the time to form a relationship with the blue team.
Speaker:Why would, if, if there's somebody that I would call in, in the time
Speaker:of a cyber attack, why would I want to get a relationship with them now?
Speaker:Because a cyber attack attack is very stressful.
Speaker:You'd rather have that relationship prebuilt so you understand what's
Speaker:expected, what each person is gonna do, the roles and responsibilities
Speaker:such that when you do have that cyber attack, everyone can just be
Speaker:like, okay, let's go, go, go, go, go.
Speaker:Everyone knows what they need to do.
Speaker:Yeah.
Speaker:You know, uh, the analogy that I'm gonna use is gonna be kind of funny and,
Speaker:and I know you know this story, but it has nothing to do with cyber attack.
Speaker:The time, the time to get a relationship with somebody like
Speaker:this is before you need them.
Speaker:Right.
Speaker:And I'm thinking about the time that I cut into the main supply line of my
Speaker:house, uh, the water sup, the water, the, the water main for my house.
Speaker:And uh, this was when I was replacing my front yard.
Speaker:I have a 400 square foot front yard.
Speaker:Right?
Speaker:It is very, you know, it's California, so my yard is not that big.
Speaker:And, uh, I was digging it up to put down, um, you know, the, I was
Speaker:gonna put down artificial turf.
Speaker:And it's kind of funny that when you put our artificial turf, the first
Speaker:thing you have to do is you have to dig up the yard and you have to, you
Speaker:dig down like six inches and then you put paver, uh, uh, base there.
Speaker:So you basically pave your yard.
Speaker:And then on top of that you put an inch of sand.
Speaker:And then on top of that you put the grass.
Speaker:Now.
Speaker:I was digging and I knew where my water main was.
Speaker:And the really funny thing is, was I don't want to damage my water main while
Speaker:I'm doing this, but I'm not a hundred percent sure what a water main is.
Speaker:So I'm just gonna dig around my water main to find my water main, to
Speaker:make sure I don't hit my water main.
Speaker:In the process, process of doing that, I hit my water main.
Speaker:Now, what does this have to do with this?
Speaker:The point was that I knew exactly where to go because there was, there's
Speaker:a guy that lives that way, like.
Speaker:300 yards from my house, and I went right to that guy's house and I was like,
Speaker:um, you know, I just did this thing.
Speaker:Luckily, luckily, I will say it was on the, on the other side of the valve that
Speaker:off.
Speaker:the water department supplies, because if I had broken it on their side, then that
Speaker:would've been a, a whole different thing.
Speaker:Right.
Speaker:Yeah.
Speaker:But, uh, it was, I remember it was like a Sunday.
Speaker:And, and by the way, cyber attacks never come when it's convenient.
Speaker:They do it on purpose, right?
Speaker:They, they, there, there will be a bunch of cyber attacks, uh, tomorrow.
Speaker:Yep.
Speaker:Uh, we're in the US tomorrow, the, the day we're recording this, tomorrow is
Speaker:July 4th, and there will be a bunch of, uh, a lot of people have a four day
Speaker:weekend because, um, you know, I think, I think it should be a federal law that
Speaker:July 4th, can't fall on a Thursday, but it is, it's on a Thursday tomorrow, so
Speaker:a lot of people will just take Friday off, so they have a four day weekend.
Speaker:This is when cyber attacks happened, right?
Speaker:So it was a Sunday afternoon and luckily I had, I had already established a
Speaker:relationship with this plumber guy, and I went over and I just knocked
Speaker:on his door and I'm like, I realize it's five o'clock on a Sunday and
Speaker:you're clearly having dinner with your family, but I just blew up my house so.
Speaker:Could you help me please?
Speaker:anything he could do that would be awesome.
Speaker:And he came over and, uh, repaired my water main, you know, I had to,
Speaker:we had to dig a big hole, a much bigger hole to get access to the pipe.
Speaker:Yeah.
Speaker:And, um, you know, and he repaired it.
Speaker:And then, uh, he said, uh, I was like, how much do I owe you?
Speaker:I was prepared for 500 bucks.
Speaker:Or more.
Speaker:And he said 150 bucks because he did it like off the clock
Speaker:and you know, his own thing.
Speaker:And I was like, dude, you know where, where do I sign?
Speaker:Right?
Speaker:You're like, thank you for saving me.
Speaker:Yeah.
Speaker:you know, calling a plumber for an emergency repair on
Speaker:a Sunday AF in the evening.
Speaker:It was gonna cost him.
Speaker:least 400 bucks before they even do anything.
Speaker:Yeah.
Speaker:And so this is what I'm saying is like, just get a relationship now.
Speaker:Get a relationship now with your local FBI department.
Speaker:Uh, by the way, Mike talked about that a lot.
Speaker:What?
Speaker:InfraGard?
Speaker:InfraGard
Speaker:was the name of the IBM, I'm sorry.
Speaker:The IRS.
Speaker:Ah.
Speaker:Not the I.
Speaker:Meant to, uh, help, uh, people combat cyber crime and, um, you know, look
Speaker:into InfraGard, get a relationship with the FBI get, uh, and or whatever
Speaker:it is where you happen to live.
Speaker:Yeah.
Speaker:And, um, but now's the time to do that.
Speaker:Any further thoughts on that?
Speaker:No.
Speaker:I think, yeah, having those pre-established relationships especially
Speaker:as these blue teams, red teams, right?
Speaker:They're probably keeping up to date on the latest of what's happening out there, so
Speaker:Yeah.
Speaker:also a great resource for that too.
Speaker:Yeah.
Speaker:You wanna, you wanna have them on speed dial, right?
Speaker:Like,
Speaker:Yeah.
Speaker:you get the thing, you make the call, they're on their way.
Speaker:Not, not, you know, I'm having a Google Blue, blue teams or cyber.
Speaker:Who do I call when I have a ransomware attack?
Speaker:Um, that's not the time to be doing that.
Speaker:It's already stressful.
Speaker:Busters.
Speaker:What's that?
Speaker:You said, who are you gonna call when you have a
Speaker:Oh, Gus
Speaker:said, ghost busters.
Speaker:that, that's a old joke, man.
Speaker:You know, you're dating yourself.
Speaker:Um,
Speaker:that's a good movie though.
Speaker:Movie, um, ruined by later attempts at.
Speaker:Sequels, but whatever,
Speaker:go there.
Speaker:We shall
Speaker:we should not go there.
Speaker:Alright.
Speaker:Good movie.
Speaker:All right, well, this has been a good episode.
Speaker:Further things that you can do to prevent ransomware and to prepare
Speaker:yourself to be able to defend ransomware if and when it happens,
Speaker:although it's more a win than an F.
Speaker:Uh, any final thoughts?
Speaker:Prasanna?
Speaker:No, uh, was a great conversation.
Speaker:I'm dying in the heat out here.
Speaker:Uh, we're in our middle of our heat wave, so
Speaker:What, what's temperature outside right now?
Speaker:I think it's 103.
Speaker:Uh, and what's the temperature inside?
Speaker:Uh, about 84.
Speaker:I really should turn on the air conditioner.
Speaker:Um, so you, you wanna know what the temperature is
Speaker:outside Where I am right now.
Speaker:75?
Speaker:75 is exactly what it's, that is San Diego versus the Bay Area.
Speaker:Um, you know, in a nutshell, um.
Speaker:Yeah, just different parts of the Bay Area, right?
Speaker:Because certain parts of the Bay Area can be quite cold, actually.
Speaker:I was looking at the thing they said up in San Francisco.
Speaker:It's in the sixties, like low sixties,
Speaker:Yeah.
Speaker:if you go to the East Bay, uh, Livermore Pleasant in that
Speaker:area, it's I think 108 degrees.
Speaker:Well, coldest winter I ever spent was the summer in San Francisco, mark Twain.
Speaker:All right.
