Prasanna Malaiyandi:

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
