What's a TLD for our listeners?
curtis:Oh, top level domain.
curtis:That's like.com or dot ransomware.
curtis:Hi and welcome to Backup Central's Restore it All podcast.
curtis:I'm your host, W.
curtis:Curtis Preston, AKA Mr.
curtis:Backup.
curtis:And I have with me, my delayed shipment consultant, Prasanna Malaiyandi.
curtis:How's it going , Prasanna?
Prasanna Malaiyandi:I'm good.
Prasanna Malaiyandi:Curtis, wait, what's delayed.
curtis:my, my, my flooring shipment, you know,
curtis:and I, I turn to you for.
Prasanna Malaiyandi:what I thought you received one.
curtis:I did I did, but . I ordered a big shipment of flooring, and then
curtis:I ordered a much smaller shipment and I did that in two shipments because
curtis:I couldn't order all of it at once.
curtis:And then I had to order like another 10% and the second shipment I received the
curtis:second shipment like three weeks ago, I still haven't received the first shipment.
curtis:And, um, I just turned to you for, for, you know, emotional
curtis:support in this time of.
curtis:I'm not doing anything until the entire shipment comes in., it's just ridiculous.
curtis:I ordered this,
Prasanna Malaiyandi:Have you heard about supply chain issues?
Prasanna Malaiyandi:Curtis has this not.
curtis:I gave them grace because of the supply chain, but here's the thing.
curtis:This is made right up the road from me.
curtis:Well, it's more like up the road from you, but it's made in California.
curtis:It's vinyl.
curtis:The manufacturing is happening in California.
curtis:But the problem is that they've lied to me.
curtis:They lied to me before.
curtis:They told me it's in production because you know, they make several colors.
curtis:They're like, oh, that color, it was really in demand.
curtis:It's in production.
curtis:Now.
curtis:They told me that like three weeks ago, they said it's in production.
curtis:It should ship out any day now.
curtis:They're now claiming they're out of stock.
Prasanna Malaiyandi:Oh,
curtis:Right.
curtis:They're like, oh yeah, we, we, we did it was in production.
curtis:We didn't lie to you.
curtis:We just didn't make enough.
curtis:Well, why did you stop the production run before you made
curtis:enough to fulfill back orders?
curtis:I mean, I get that.
curtis:You're behind.
curtis:I get that you had a big promotion, but retooling, the production line is a pain.
curtis:Right.
curtis:So why would you retool it
Prasanna Malaiyandi:Maybe they ran out of
curtis:of color.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:Whatever.
curtis:So this is why you're here.
curtis:You're here to make me not so angry.
curtis:That's why I said you're my delayed shipment consultant.
curtis:All I know is it's not in my hot little hands and I'm not doing squat in my
curtis:garage until I get the entire shipment.
Prasanna Malaiyandi:Just think though.
Prasanna Malaiyandi:How about delayed gratification?
Prasanna Malaiyandi:Once you finally get the pallets
curtis:This is the ultimate in delayed gratification.
curtis:I've never had so much trouble spending money in my life.
curtis:Right.
curtis:I mean, and that even includes the two recent, very expensive
curtis:couches that we bought.
curtis:There were way more expensive than this.
curtis:Um, we ordered it and then they were like, it's in a ship off long beach.
curtis:If you want to see your couches go to the long beach Harbor and look out into
curtis:the water and you can see, and that was, that was promised like four weeks.
curtis:And it was more like eight, but at least there, I was like, well, I'm part of
curtis:the whole, you know, shipment problem.
curtis:And I just had to wait, but here it's just frustrating because they,
curtis:because they've miscommunicated,
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:I think that's the problem, right?
Prasanna Malaiyandi:If they had not given you any information that yeah.
Prasanna Malaiyandi:It's in production, right.
Prasanna Malaiyandi:You probably would have been fine.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:It's just shipping delays.
Prasanna Malaiyandi:That's fine.
Prasanna Malaiyandi:The fact that they told you now you're annoyed.
curtis:Hashtag
Prasanna Malaiyandi:it'll be
curtis:#firstworldproblems.
Prasanna Malaiyandi:Take a deep breath.
curtis:Yeah, good times.
curtis:Good times.
curtis:Um,
curtis:Our disclaimer, Prasanna works for Zoom.
curtis:I work for Druva and, uh, the opinions that you hear are ours.
curtis:This is not a podcast of either company.
curtis:And a rate us at ratethispodcast.com/restore, or just
curtis:click on your favorite pod catcher.
curtis:And, uh, click down to the bottom and give us some stars, or maybe even a comment.
curtis:Talk about how much you love Prasanna's beard.
curtis:I'm good with that.
curtis:And how it's so much longer and darker than mine and.
curtis:And, uh, you know, if you're, if you're curious about such things, if any of
curtis:these things, we talk about excite you either way then, uh, you know, @wcpreston
curtis:on Twitter or wcurtispreston@gmail and, uh, you'll find me.
curtis:So I see.
curtis:I sent you this, this post that I, that I saw on Reddit, which it's well,
curtis:it's actually a series of three posts from a Reddit user called snorkel42.
curtis:Don't let his, you know, snorkeling ID fool you the, the person
curtis:knows what they're talking about.
curtis:I don't know.
curtis:I don't know anything about this person.
curtis:Other than that, they, they have, they post regularly in a
curtis:subreddit called security cadence.
curtis:Um, but he also posted he or she, I don't know if I mistaken
curtis:mistakenly called the person.
curtis:He, I apologize in advance for my misogeny, so.
curtis:The, it was about ransomware and, and they are a specialist in the areas
curtis:of security and many people had asked them to post stuff about ransomware
curtis:and they had continually sort of said, I don't want to post about ransomware.
curtis:And can you imagine why that would be
Prasanna Malaiyandi:You're just sort of propagate well, it's ransomware you get
Prasanna Malaiyandi:hit with, because there were a bunch of gaps before ransomware got hit and it's
Prasanna Malaiyandi:better to address the problem rather than trying to address sort of the outcome.
curtis:Yeah.
curtis:So ransomware to this person is the symptom of a whole lot of bad things
curtis:that you were already doing or not doing.
curtis:And they've spent their career helping to make sure you do those things.
curtis:But with the, I think two things, one is that obviously the ransomware attacks are
curtis:getting to a fever pitch and then two.
curtis:There is what we talked about on the previous episode, which was this concern
curtis:about Russia and D w we did cover that.
curtis:Didn't
curtis:we?
Prasanna Malaiyandi:Yeah, we cover the Conti ransomware gang
curtis:Yeah.
curtis:Yeah.
curtis:Um, yeah, the, the, the Krebs on security post.
Prasanna Malaiyandi:Yep.
curtis:That the concern is that the level of the fever pitch that we're experiencing
curtis:might actually go through the roof.
curtis:And so they said, Hey, I'm gonna finally, I'm fine, fine.
curtis:I'll post about ransomware, but even in their post about ransomware, it
curtis:really wasn't that much about ransomware as much as it was about the things.
curtis:Well, no, that's not true.
curtis:I'll take that back.
curtis:It was, it was here is the way ransomware works.
curtis:And so I I'd say the first one, I'd say of the three series,
curtis:The first one was about here's how to prevent it.
curtis:Number one, like from getting in.
curtis:The second was here's how to prevent it from doing more damage once it's in.
curtis:And then the third one, it was okay.
curtis:All right.
curtis:You're totally screwed.
curtis:You've got to reach for your backups.
Prasanna Malaiyandi:Yeah.
curtis:that
Prasanna Malaiyandi:The one thing I would add to that , is he also was careful
Prasanna Malaiyandi:saying, I don't want to just focus on the Conti ransomware and provide you steps
Prasanna Malaiyandi:to prevent that because there are so many other ransomware flavors out there.
Prasanna Malaiyandi:If you build something for just one.
Prasanna Malaiyandi:You're not going to be protecting yourself.
Prasanna Malaiyandi:Let's take a holistic approach.
Prasanna Malaiyandi:And like you said, let's cover, how do you prevent it from getting in?
Prasanna Malaiyandi:What, how do you prevent the spread of it?
Prasanna Malaiyandi:And then how do you recover?
curtis:Yeah.
curtis:Good point.
Prasanna Malaiyandi:The first one is called initial breach, I think
Prasanna Malaiyandi:is how he titled the first article.
curtis:Right.
curtis:So the phishing basically, they're saying That That is the number
curtis:one way that you get ransomware.
Prasanna Malaiyandi:Yep.
Prasanna Malaiyandi:Someone accidentally clicking an email, opening up something,
Prasanna Malaiyandi:letting the attackers in, and they don't even know about it.
Prasanna Malaiyandi:So how do you prevent your users from clicking on malicious links?
curtis:now, now, it's interesting.
curtis:This goes, yeah.
curtis:Sorry.
curtis:This goes somewhat against what, some of the advice of one of the guests
curtis:that we had on the podcast, which was, they basically said, look, your
curtis:people are going to click on stuff, stop relying on, you know, I dunno.
curtis:I dunno if it's against, but, but he, he, de-prioritized training and, and like, uh,
curtis:phishing assessments, didn't you think.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:So.
Prasanna Malaiyandi:This author does say training can only help you so much?
Prasanna Malaiyandi:I think the couple things, the couple things though, that he did mention is,
Prasanna Malaiyandi:um, you do need some level of training, but you need to make sure people don't
Prasanna Malaiyandi:feel like they're being punished.
Prasanna Malaiyandi:When they do the wrong thing, right?
Prasanna Malaiyandi:You want that transparency.
Prasanna Malaiyandi:You want to be telling people it's okay for you to say that I clicked
Prasanna Malaiyandi:the wrong thing because then the IT team can try to evaluate what's
Prasanna Malaiyandi:going on and try to contain it.
Prasanna Malaiyandi:The sooner they know the better it is.
Prasanna Malaiyandi:But if say someone's afraid because they're going to get in trouble.
Prasanna Malaiyandi:They might be fired, right.
Prasanna Malaiyandi:It becomes taboo then no one's going to report it.
Prasanna Malaiyandi:And that's actually really bad.
curtis:Yeah.
curtis:Um, they said to prioritize rewarding over punishment.
curtis:Right?
curtis:Make it, make it known.
curtis:Like you said, that it's okay to call in.
curtis:We want you to call in, even if you messed up and, and then, and
curtis:they also said consider doing your own phishing assessments.
curtis:I read some of the comments and they talked about that.
curtis:They had a thing where you, you, you got some.
curtis:You got some, it was sort of some strikes and it was like 10 strikes.
curtis:It was like, you could click on 10 malicious emails.
curtis:And, and then it was the 10th.
curtis:When, and that they actually had a series of escalations where, you
curtis:know, it started out, Hey, you know, we really told you kind of thing.
curtis:Um, I think you can do both.
curtis:I think you can do both carrot and stick, right.
curtis:Reward and punishment where yes.
curtis:You want to reward people for calling in.
curtis:Thank you for calling accidentally clicked and then.
curtis:And then if the person clicks doesn't know, but you know, because you did a
curtis:phishing assessment, you do a series of escalating things where that
curtis:ultimately you can have a person.
curtis:And this was discussed in the comments, not necessarily that you
curtis:would fire somebody that, that keeps doing this, but you might say, okay,
curtis:this person cannot be trusted with a straight internet connection.
Prasanna Malaiyandi:Yup.
curtis:Right.
curtis:All email from this person will be monitored.
curtis:Yeah.
curtis:They can only open email that's straight from our Exchange server
curtis:or whatever stuff like that.
Prasanna Malaiyandi:So phishing was sort of one way that people get in.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:But I think once they're in whichever mechanism it is, it's like, okay,
Prasanna Malaiyandi:how do you detect that someone's in?
Prasanna Malaiyandi:And I think Curtis, this is what you're going to say, right.
Prasanna Malaiyandi:About sort of this notion of droppers.
curtis:Yeah, I actually didn't know this part.
curtis:That's I was fascinated that that basically that the actual phishing
curtis:results in a very small piece of software whose job it is to install
curtis:the actual piece of software
Prasanna Malaiyandi:Yeah.
curtis:and that he calls out a dropper.
Prasanna Malaiyandi:Yep.
curtis:Well, and so the idea is understand that that's the way it works,
curtis:that a piece of code gets dropped in, and then that piece of code executes, and
curtis:the only purpose of that piece of code is to download the other piece of code.
curtis:And so they said that you could, you could stop that.
curtis:You could say, well, you can't run arbitrary pieces of code in,
curtis:in locations that are directly accessible by the end user,
curtis:you know,
Prasanna Malaiyandi:Or you could restrict what applications are allowed
Prasanna Malaiyandi:to run on a laptop for instance,
curtis:yes,
curtis:Whitelisting, I think whitelisting is it, I think it's the, the best.
curtis:The best way to stop stuff like this.
curtis:It's also the highest touch because it means that every new
curtis:application that anybody has to install, they have to get approval.
Prasanna Malaiyandi:Yep.
Prasanna Malaiyandi:think it's a way to guarantee sort of legitimate applications have gone through
Prasanna Malaiyandi:some sort of validation process, security review, et cetera, before it's being
Prasanna Malaiyandi:allowed to be deployed in your environment
curtis:Right.
curtis:And then the next thing it talked about was that a random file
curtis:running should not be downloading files from the internet, right.
curtis:That it should only be HTTP and HTTPS is downloading from the internet.
curtis:And so.
curtis:He said with exceptions, like, you know, um, uh, SFTP for example.
curtis:So he talked about, he talked about, you know, again, accessing that also
curtis:possibly blocking bizarre TLDs right.
curtis:And unnecessary locations.
curtis:You could just simply say, listen, uh, we don't have anything to do with Russia.
curtis:Why would we download anything from Russia?
curtis:And if there is somebody in our company that needs to download stuff from Russia,
curtis:they will be, they will be accepted.
curtis:That was a very running theme I heard was lock down everything and allow exceptions.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:And, uh, it was going to bring up two things.
Prasanna Malaiyandi:One was what's a TLD for our listeners?
curtis:Oh, top level domain.
curtis:That's like.com or dot ransomware.
curtis:There is no dot
curtis:ransomware,
curtis:but.
Prasanna Malaiyandi:And was it you, or was it one of our guests who were, who
Prasanna Malaiyandi:was talking about how they worked at a company that completely locked down
Prasanna Malaiyandi:their network and the network admin would never let them do their backups
Prasanna Malaiyandi:and everything was by except.
curtis:That was me.
curtis:Yeah.
curtis:Yeah.
curtis:Uh, that was, I was a client of mine where they had internal firewalls and
curtis:that's an example of, you know, going to the extreme of, well, now you're now
curtis:you're preventing core business functions,
Prasanna Malaiyandi:Yeah,
curtis:right?
Prasanna Malaiyandi:but
curtis:they also talked about local firewalls, right.
curtis:Which is what we were just talking about, that the, and we're going to get
curtis:to that more in the next section is, so they're just looking, he's looking
curtis:for ways to stop the dropper from getting yeah, exactly.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:thought was an interesting point I'd never thought about is he does have a point
Prasanna Malaiyandi:about they block newly created domains.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:Which I thought that had been dormant for a while and then are now active,
Prasanna Malaiyandi:which I thought was very interesting because it's something I had never
Prasanna Malaiyandi:thought about, but it totally makes sense.
Prasanna Malaiyandi:Usually when you get ransomware, right.
Prasanna Malaiyandi:These actors, they spin up domains and they start
Prasanna Malaiyandi:communicating, using that domain.
Prasanna Malaiyandi:So he's like, yeah, you could have a policy to just block these domains.
Prasanna Malaiyandi:So they can't actually reach back out to the command and control
Prasanna Malaiyandi:servers to be able to download from the dropper, the actual exploit.
curtis:Right.
curtis:And, and they said they weren't aware of anything.
curtis:Where that you can do this for free, but there are tools that are
curtis:available to help you do This right.
curtis:There's
Prasanna Malaiyandi:remember, uh, what are the D D.
Prasanna Malaiyandi:Uh, what were the initials?
Prasanna Malaiyandi:The DNS
curtis:DDI.
Prasanna Malaiyandi:right.
Prasanna Malaiyandi:And I think that goes to some of that as well.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:Where it's like, Hey, if you have some of those controls in place, you can now
Prasanna Malaiyandi:prevent unauthorized access to domains.
Prasanna Malaiyandi:They should not be having access to.
curtis:Exactly.
curtis:And then they started talking about preventing lateral movement inside.
curtis:Think about the ways that people need to move within your organization and allow
curtis:that, but block all other movement, right.
curtis:Lateral movement between servers and I, and I think, again, going back
curtis:to that company, that was a perfect example of, they had blocked all
curtis:lateral movement between all servers and I couldn't get my job done.
curtis:They're only problem w and they should have done that.
curtis:And, you know, they were forward thinking in that regard, but you do need to allow
curtis:exceptions for things like backup, right.
curtis:That is definitely a server to server lateral movement.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:And it's also other simple things.
Prasanna Malaiyandi:Like one of them was your favorite topic, right?
Prasanna Malaiyandi:Locking down RDP and SSH.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:If it's not needed, then lock it down.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:SMB is the same way as well for vCenter, right?
Prasanna Malaiyandi:Figuring out what actually needs access and what.
Prasanna Malaiyandi:Needs to be available to the internet.
Prasanna Malaiyandi:And one of the points he made is you should just assume that
Prasanna Malaiyandi:your inner internal network is as hostile as internet access.
Prasanna Malaiyandi:Right?
Prasanna Malaiyandi:So once an exploit happens, you can't trust anything internally.
curtis:They were also, I, you know, I didn't necessarily
curtis:agree with this one here.
curtis:And that was it's time to kill monolithic file servers.
curtis:Right.
curtis:Now I don't have a problem with the file server.
curtis:It's just, I think when, when they mean monolithic file server, they're just
curtis:saying a file server where everybody in the company can access all the data.
curtis:I would agree there anybody that's doing that, you know, in a
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:Segregate the data isolate to departments that need access.
Prasanna Malaiyandi:You use ACLs, make sure the people who need access have access and
Prasanna Malaiyandi:then monitor who's accessing what.
curtis:So they made a specific example of like, you know, just because just
curtis:because accounts receivable gets attacked, something shouldn't happen to payroll.
curtis:These are, these are both finance functions, but they're separate
curtis:financial functions and they should have their own areas.
curtis:Uh, and this is another one that I harp on is about protecting
curtis:privileged credentials.
curtis:And
Prasanna Malaiyandi:don't just have your password tattooed
Prasanna Malaiyandi:on your forehead, Curtis.
curtis:They recommended implementing, uh, things like LAPS, which I had
curtis:to look up, which stands for local administrator password solution.
Prasanna Malaiyandi:Uh, setting a different random password for
Prasanna Malaiyandi:the common local admin account on every computer in the domain.
Prasanna Malaiyandi:So you don't use one password for everything.
curtis:And then MFA, I think, I think every system, you know, every, every
curtis:privileged account needs to have MFA and, you know, I'm sorry, that's a pain.
curtis:I, you know, I use it all the time, but it what is
Prasanna Malaiyandi:but wait, why do you need a privileged account?
Prasanna Malaiyandi:You should.
Prasanna Malaiyandi:Here's the thing.
Prasanna Malaiyandi:Most times you should probably not need privileged accounts, so you do not need
Prasanna Malaiyandi:to access your privileged accounts.
curtis:Agreed, but, but they have to exist.
curtis:And so you have to lock them down this way.
curtis:I think what you're saying is MFA, shouldn't be that big of a deal for you.
curtis:If you set up modern administration.
Prasanna Malaiyandi:yeah.
Prasanna Malaiyandi:And you should rarely be using that.
curtis:Right.
curtis:Right.
curtis:And then very last on the list and I would have put it first, but you know, it's
curtis:just me and that was patching your stuff.
Prasanna Malaiyandi:How many times does that come up on the podcast?
Prasanna Malaiyandi:When we talk about ransomware, you know,
curtis:Yeah, exactly.
curtis:So the next one is about.
curtis:It's like, okay, so you got some ransomware.
curtis:Let's talk about the things that they're going to try to do.
curtis:The very first thing they listed was deleting of shadow copies.
curtis:And so I, and really shadow copies are basically like he's talking
curtis:about windows shadow copies.
Prasanna Malaiyandi:Yeah, I think windows shadow copies.
Prasanna Malaiyandi:Yup.
curtis:Right.
curtis:And so there is a tool here, which I had never heard of called raccine.
curtis:And it, it stops you from deleting shadow copies.
curtis:He said it stops everybody from deleting them.
curtis:So just realize that if you've got some regular thing that regularly deletes
curtis:shadow copies, it'll break that, but it looks it's something on github.
curtis:So it's, uh, you know, it's an open source tool.
Prasanna Malaiyandi:And just reading that briefly, I think many backup
Prasanna Malaiyandi:tools when you're backing up windows applications uses shadow copy.
Prasanna Malaiyandi:So be careful if you are using that because you may not
Prasanna Malaiyandi:be able to do your backups.
curtis:Yeah, that's a good question.
curtis:I, I guess, you know, I would differentiate between shadow
curtis:copies made just for the purposes of backups and shadow copies that
curtis:are made and then left there.
curtis:I don't know if there's like a different.
curtis:I know that when you make a snapshot, you say why you're making the snapshot.
Prasanna Malaiyandi:Yeah.
curtis:Um, but agreed that this is not something that you're just
curtis:going to download and just implement,
Prasanna Malaiyandi:Yeah.
curtis:might break all your backups.
curtis:Well, what it might do is it might allow you to create that snapshot,
curtis:but then it leaves all those snapshots around and let you delete them.
curtis:and you might get an error on your backup because you can't,
curtis:it can't delete the snapshot.
Prasanna Malaiyandi:yeah.
Prasanna Malaiyandi:Or your production could run out of space and then your app dies.
curtis:And then what's the next one
Prasanna Malaiyandi:So the next one is a common theme for us.
Prasanna Malaiyandi:Uh, when we talk about ransomware, it's less about the actual encrypting of data.
Prasanna Malaiyandi:It's the fact that these ransomware actors, especially the Conti group,
Prasanna Malaiyandi:they like to exfiltrate your data and steal sensitive data, and then hold you
Prasanna Malaiyandi:hostage and be like, Hey, you want to pay?
Prasanna Malaiyandi:Then you have to pay twice once for the decryption key.
Prasanna Malaiyandi:And then once to make sure we don't publish your data.
Prasanna Malaiyandi:And then sometimes they will still go and publish your data.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:So in this post, he talks about sort of, how can you make sure
Prasanna Malaiyandi:you can detect data exfiltration?
Prasanna Malaiyandi:And he talks about everything from, if you have, if you understand network
Prasanna Malaiyandi:patterns, you could look for anomalies.
Prasanna Malaiyandi:Um, you can also look at other tools.
Prasanna Malaiyandi:To see when data is actually being read and sent.
Prasanna Malaiyandi:So there's some interesting tools that he talked about.
Prasanna Malaiyandi:One that I never thought about, which was this mechanism called, uh,
Prasanna Malaiyandi:from things called Canary tokens,
Prasanna Malaiyandi:where it basically creates a false file.
Prasanna Malaiyandi:And any time someone accesses it, it generates a token and sends it home.
Prasanna Malaiyandi:And then it'll send you an email, say, Hey, by the way,
Prasanna Malaiyandi:someone accessed this file.
Prasanna Malaiyandi:So you can sort of get notified of, Hey, someone's accessing something, which
Prasanna Malaiyandi:they probably normally never should be.
Prasanna Malaiyandi:Because most of this ransomware software and data exfiltration, it's
Prasanna Malaiyandi:just programmatically reading, like scanning folders, reading files, right.
Prasanna Malaiyandi:Trying to figure out what to send.
curtis:Right.
curtis:And they mentioned both commercial solutions and open source solutions.
curtis:Like the one you mentioned, they also mentioned something called, uh, Zeke,
curtis:which, uh, And you know, that it analyzes NetFlow, but there are commercial
curtis:tools, which we've mentioned on here.
curtis:Um, and I, and I'd like to get, I'd like to get more of those companies on here.
curtis:And their recommendation was the same as mine, which is looking
curtis:for something that uses behavioral analytics to determine what is, and
curtis:is not a normal file transfer, right.
curtis:That should be able to spot a massive, uh, exfiltration attack..
curtis:And then the response against encryption, they talked about the EDR
curtis:XDR, which is I had to look that up.
curtis:I was not in my, so this is what,
Prasanna Malaiyandi:And point D
Prasanna Malaiyandi:endpoint detection and response.
curtis:right.
curtis:Okay.
curtis:So.
curtis:The idea is that if you've got, if you've got the money to put something
curtis:on each laptop that basically looks at and stops, massive file modifications,
curtis:it would detect and stop those.
curtis:Right.
curtis:And then same thing with the, with the honeypot.
curtis:I liked the idea with the creating an entire separate file server that has,
curtis:has all the same file names, but just with junk data, watch for anybody doing
curtis:anything there and then report on.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:And the interesting thing is when he was talking about honeypots, I didn't
Prasanna Malaiyandi:know, this is, he was like, oh yeah.
Prasanna Malaiyandi:And then to make it more realistic, you, there are a couple things you can do.
Prasanna Malaiyandi:You can map those device shares to actual endpoint devices.
Prasanna Malaiyandi:So they show up there because if I'm a ransomware program and I'm just looking
Prasanna Malaiyandi:at all the devices attached, right.
Prasanna Malaiyandi:I don't know if it's real or not.
Prasanna Malaiyandi:And the question came up, Hey, how do you hide it from your end users?
Prasanna Malaiyandi:Because you don't want your end users clicking on it as well.
Prasanna Malaiyandi:And there are registry commands in Windows, so you can actually hide them.
Prasanna Malaiyandi:So your users don't actually see those drives.
Prasanna Malaiyandi:And instead he suggested you actually bookmarked.
Prasanna Malaiyandi:Shared drive letters with these honeypot shared drives because ransomware,
Prasanna Malaiyandi:uh, programs are either going to start from a and work alphabetically
Prasanna Malaiyandi:or start from Z and come backwards, to see what drives are available.
Prasanna Malaiyandi:And then they'll just start looking that way.
curtis:So, so put a honeypot at a and put a honeypot at z.
Prasanna Malaiyandi:Yup.
curtis:I like um,
Prasanna Malaiyandi:were some really interesting things that he talked about.
curtis:And we can only cover a little bit here.
curtis:I just would highly recommend anybody that's interested in this, which should
curtis:be everybody go read this thread.
curtis:It's really well-written thread
Prasanna Malaiyandi:It's like how to trick ransomware
Prasanna Malaiyandi:and how to protect yourself.
curtis:Right.
curtis:then
Prasanna Malaiyandi:jump onto the third?
Prasanna Malaiyandi:Curtis.
curtis:Yeah.
curtis:Get up on the third?
curtis:one.
Prasanna Malaiyandi:Sorry, what is the third one about by the way?
curtis:Oh, the third one well, basically it's like, well, you've been infected.
curtis:What are we going to do?
curtis:Worst case scenario you've been infected and it's spread, and now
curtis:you need to reach for your backups.
curtis:So they mentioned go to the, the, the incident response plan.
curtis:And of course that assumes that you have one, which we've said
curtis:that you need to have one, right?
curtis:We we've mentioned repeatedly that a ransomware attack is
curtis:not the same as a disaster.
curtis:There are elements that I'd say a disaster is a subset of.
curtis:Uh, typical DR response is a subset of a, of a ransomware attack response.
Prasanna Malaiyandi:Think people get confused because in the end you're
Prasanna Malaiyandi:trying to do the same things, right.
Prasanna Malaiyandi:Get your data up.
Prasanna Malaiyandi:But I think the steps and the number of people, the different types of
Prasanna Malaiyandi:people involved are significantly different between just a normal DR.
Prasanna Malaiyandi:Versus a ransomware recovery.
curtis:Well, you know, simplistically to me, the biggest difference between,
curtis:uh, responding to a ransomware attack and a disaster, it'd be the
curtis:equivalent of like, if you're doing a DR and you've had a flood step
curtis:number one is drain the data center,
curtis:right?
curtis:Get all the water out of the data center.
curtis:Well, a ransomware attack is like, you're trying to drain the data center while you
curtis:have a person standing there with a fire hose, it's filling up your datacenter.
curtis:Right?
curtis:the, that's the difference between a disaster recovery and a
curtis:ransomware recovery is that they are actively still attacking you.
curtis:And you're actively experiencing the disaster at the same time as
curtis:you're trying to recover from it.
curtis:And so they've got a good thing here on what should be
curtis:in an incident response, right?
curtis:Some things you have to have in your incident response plan
curtis:got eight things about right.
curtis:Procedures and policies and an incident firm.
curtis:Right.
curtis:You, you need, you basically get professionals, retain them now, right?
curtis:Oh, by the way, I just, I just gotta throw out a really hilarious thing from,
curtis:uh, my granddaughter Lily yesterday.
curtis:So we have a friend, a mutual friend that was in a car accident a while back.
curtis:Not, not seriously injured, but injured enough that there is a lawsuit that
curtis:our, that, that that's going on.
curtis:And Lily said, uh, she, you know, she, she mentioned that I couldn't, she couldn't
curtis:pick her up because, you know, she was with her, she was with her lawyer and
curtis:then she looks at me, we were just walking and then she's like, do I have a lawyer?
curtis:I was like, no, I don't think you have a lawyer.
curtis:You don't need a lawyer right now.
Prasanna Malaiyandi:
Speaker:But, but you're right.
Prasanna Malaiyandi:
Speaker:Most people don't even think about that.
Prasanna Malaiyandi:
Speaker:Like even in like everyday, like normal situations, it's like, if
Prasanna Malaiyandi:
Speaker:I, God forbid get arrested, right.
Prasanna Malaiyandi:
Speaker:Who am I going to call?
Prasanna Malaiyandi:
Speaker:It's like,
curtis:Right.
curtis:Yeah.
curtis:And so w what they're saying here is, you know, go, go find who you're going to hire
Prasanna Malaiyandi:who are you going to call Ghostbusters?
curtis:going to call?
curtis:And, um, you know, and they got a policy, oh, a policy.
curtis:This is interesting policy for informing partners and customers and the media.
curtis:Right?
curtis:Decision-makers right.
curtis:All of that stuff.
curtis:This should all be decided upfront.
curtis:You should be deciding that now.
curtis:I don't know how many times we can say that.
Prasanna Malaiyandi:Yep.
Prasanna Malaiyandi:And then they talk about restoring your data.
curtis:Restoring your data.
curtis:right?
curtis:And I think how they said alright, three posts in and we
curtis:can finally talk about backups.
curtis:Right.
curtis:It's interesting here.
curtis:Right?
curtis:And he talks about, you know, the typical call-out is that ransomware's
curtis:going to target your backups.
curtis:And so you need some sort of immutable backup solution.
curtis:Right.
Prasanna Malaiyandi:Um, he does also talk and I know Curtis, you're probably
Prasanna Malaiyandi:going to have concerns with this, right?
Prasanna Malaiyandi:That you don't have to be offsite to protect your backups properly.
Prasanna Malaiyandi:He mentions that you could use strict network segmentation or other
Prasanna Malaiyandi:mechanisms to ensure separation, which would protect you in the case
Prasanna Malaiyandi:of ransomware, but may not protect you from all disasters that could occur.
curtis:Agreed.
curtis:And, and, and I don't, I don't have an issue with that, right.
curtis:Obviously, you know, I'll say obviously I work at a service-based backup company.
curtis:And we see that as the easy it's easy peasy.
curtis:All our backups are off site.
curtis:I I'm not against, you know, as a backup expert, I'm not against onsite backups.
curtis:There's a lot of good reasons for an onsite copy, but I completely agree
curtis:with this person that you have to protect that onsite copy from attacks.
curtis:And there are a lot of very common backup designs, incredibly common backup designs
curtis:that do not that the default installation of those products do not protect you.
curtis:Right.
curtis:And I, and I'll, you know, I don't wanna, I don't wanna pick on our friends at
curtis:Veeam, but that's a perfect example.
curtis:The guys from Veeam came on here and they explained to you, if you listen,
curtis:if you, if you haven't seen those episodes, go back and listen to them.
curtis:Uh, about, you know, when they talked about the, the Conti ransomware attacks
curtis:and how you can configure your Veeam backups to protect against that.
curtis:My concern is that most of their customers are not listening to this podcast, by
curtis:the way, they're more than welcome.
curtis:All 700,000 Veeam customers are more than welcome to come listen to the podcast.
curtis:But if, if you just do the default installation and you don't take their
curtis:recommendations on how to further protect your data, you know, it's no different
curtis:than any of the other products, right?
curtis:So
Prasanna Malaiyandi:Read
curtis:you've got to stop doing that.
curtis:Read the manual, read the best practices.
curtis:Call Rickatron.
curtis:Rickatron'll sort, you out and.
curtis:So he talks about that.
curtis:He also talks about testing, testing, your backups.
curtis:I'm editing right now, like literally in I'm in the middle of editing
curtis:the podcast, the episode of the restore test gone horribly wrong.
Prasanna Malaiyandi:backup.
curtis:It's going to be a great episode.
curtis:The.
curtis:Yeah, Schrodinger's backup.
curtis:Exactly.
curtis:That's going to, if, yeah, if you haven't heard that episode
curtis:go back and listen to it.
curtis:It's a, it's a
Prasanna Malaiyandi:Yeah.
curtis:uh,
curtis:episode.
Prasanna Malaiyandi:article also refers to it, right?
Prasanna Malaiyandi:Yeah.
curtis:yes, he does.
curtis:Uh, did he, did he actually refer to Shrodinger's
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:HInging your company's future on a schrodinger's backup thought
Prasanna Malaiyandi:experiment is a terrible idea.
Prasanna Malaiyandi:Don't do that.
curtis:Nice.
curtis:So, and then why don't you talk about the decryption part?
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:So I guess the final part right.
Prasanna Malaiyandi:Is you've been hit with encryption, right?
Prasanna Malaiyandi:So now what do you do?
Prasanna Malaiyandi:And in most cases, it's.
Prasanna Malaiyandi:You can try to get, like, if you're lucky, there might be a free
Prasanna Malaiyandi:decryptor out there for your data.
Prasanna Malaiyandi:It's just going to take a very long time.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:And if you do pay the ransom and you have to understand that paying the ransom may
Prasanna Malaiyandi:be illegal to some of these groups, right?
Prasanna Malaiyandi:They'll give you back a decryption key.
Prasanna Malaiyandi:Hopefully it'll work.
Prasanna Malaiyandi:It's not, it's in the ransomware.
Prasanna Malaiyandi:Group's best interest not to cheat you there, but you're
Prasanna Malaiyandi:taking a risk there as well.
Prasanna Malaiyandi:And then finally, Once you've actually decrypted your data.
Prasanna Malaiyandi:You've gone back up and running.
Prasanna Malaiyandi:There's nothing that prevents them from either coming back
Prasanna Malaiyandi:and attacking you again, if you haven't fixed anything right.
Prasanna Malaiyandi:Or the next group coming back.
Prasanna Malaiyandi:Cause that's another common thing you see is one group gets in encrypts your data.
Prasanna Malaiyandi:Another group figures out a different mechanism because they
Prasanna Malaiyandi:know now that you're willing to pay.
Prasanna Malaiyandi:And so they might come after you as well.
Prasanna Malaiyandi:So even once you have your data decrypted, it's not the end of the story.
curtis:Right.
curtis:And then the there's a, there's a what's next and, and, and all of
curtis:these words, and this is a really long series of posts, which I highly
curtis:recommend you go look through.
curtis:There's one part where they typed in all caps, and this is it right when
curtis:you're done, whatever you did restore, pay the ransom, whatever it is.
curtis:It's not over, you clearly have a serious gap in your defenses.
curtis:You need to find these and fix them.
curtis:And then this is all caps and you need to understand that those gaps are bigger
curtis:than just whatever the initial breach vector was as highlighted in parts one
curtis:and two of this series, there are several opportunities to stop a ransomware
curtis:breach before it gets to this point.
curtis:So, um, there, there was some other.
curtis:It was another one that I read, uh, somebody, they said, well, if I, if
curtis:I, if I was at a company that had a highly, I think it was actually in here.
curtis:If I was at a company that a highly publicized breach does this hurt my
curtis:chances of getting a job and the author of this article didn't think so, because they
curtis:basically said you now have experience
Prasanna Malaiyandi:Yep.
Prasanna Malaiyandi:I think it was actually at the end of this article is where he wrote about that.
Prasanna Malaiyandi:Yeah.
Prasanna Malaiyandi:He's like, yeah.
Prasanna Malaiyandi:It's something you should actually show that you've gone through this because for
Prasanna Malaiyandi:a lot of people it's just theoretical.
Prasanna Malaiyandi:They've never experienced it.
Prasanna Malaiyandi:It's like you Curtis.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:I can sit here and talk about like how to back up your data, how to restore
Prasanna Malaiyandi:your data, ideally how it should be done.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:But I've never cut my teeth in a production environment, trying to do a
Prasanna Malaiyandi:restore with people, yelling at me over my shoulder or watching over my shoulder.
Prasanna Malaiyandi:Right.
Prasanna Malaiyandi:You have, and I think that's sort of the difference, right?
Prasanna Malaiyandi:Is you have that experience because trial by fire.
curtis:Yeah, I, you know, you just, you just reminded me of, and I know
curtis:I've told this story before, but not everybody's listening to every episode.
curtis:My, one of my favorite restore stories was, was back at my first big job.
curtis:And we had somebody in the NOC that was coordinating the various things that
curtis:were happening of this big restore.
curtis:And we had another guy that was in the data center that
curtis:was actually doing things and.
curtis:He was talking to the person who was on the phone in the NOC.
curtis:And he, he didn't know that he was on speaker.
curtis:And so he said, he's like, oh, so you know where you are.
curtis:I'm in the NOC.
curtis:He goes, oh, so I suppose you have Tom and Tom standing on
curtis:your left and right shoulder.
curtis:And he was referring to our boss's boss and our boss's boss's boss.
curtis:Right.
curtis:And, um, the, uh, that would be Tom Thomaides and Tom Lackey.
curtis:And they were indeed standing both on his left and right shoulder.
curtis:And they said that when he said that, oh, so you have Tom and Tom standing
curtis:on your left and right shoulder.
curtis:He said they just both took one step back.
Prasanna Malaiyandi:but it's true, right?
Prasanna Malaiyandi:It's a stressful thing everyone's watching to make sure it goes perfect.
curtis:Right.
curtis:And, um, so, you know, we wish you all the best of luck.
curtis:I continue to be concerned about our, our friends over there in the Ukraine.
curtis:And, uh, we wish them the best of luck and.
curtis:You should also be concerned about the potential ramifications that all of
curtis:that has on continued further attacks on your data center and read this
curtis:article, read every word of this article, not just this summary and, um, you
Prasanna Malaiyandi:the three
curtis:read all three parts and we'll, we'll put links to
curtis:it in the show description so that you can easily find it.
curtis:Cause finding stuff on Reddit is not necessarily easy.
curtis:So, uh, Thanks again Prasanna for your wise, uh, shipping advice
curtis:and, um, you know, a good, good commentary on article well.
Prasanna Malaiyandi:anytime Curtis and I hope I know, normally when we talk
Prasanna Malaiyandi:about ransomware, you get very depressed.
Prasanna Malaiyandi:So I, it feels like this isn't a depressing article.
Prasanna Malaiyandi:It feels like here are things you should be doing.
Prasanna Malaiyandi:So
curtis:Here are things that you should do now.
Prasanna Malaiyandi:Yeah,
curtis:Yeah, absolutely.
curtis:So, all right, well, thanks to the listeners.
curtis:Uh, you know, we'd be nothing without you remember to subscribe
