Uber and LastPass breaches – is 2FA all it’s cracked as much as be? [Audio + Text]

With Doug Aamoth and Paul Ducklin.

DOUG. Uber hacked, extra on the LastPass breach, and Firefox 105.

All that, and extra, on the Bare Safety Podcast.

[MUSICAL MODEM]

Welcome to the podcast, all people, I’m Doug Aamoth.

With me, as all the time, is Paul Ducklin…

[DRAMATIC VOICE] …the host of Safety SOS Week, a star-studded lineup of interviews with safety specialists working from 26-29 September 2022.

DUCK. I just like the sound of that, Doug. [LAUGHS]

DOUG. Sure!

DUCK. Please be part of us subsequent week, people.

It’s the final week of September.

We selected that as a result of it’s the week main as much as Cybersecurity Consciousness Month – that’s not a coincidence.

So, 26, 27, 28, and 29 September 2022.

Every day there’s a 30-minute interview with one among 4 totally different specialists at Sophos.

We’ve received Fraser Howard, malware professional extraordinaire.

We’ve received Greg Rosenberg, who will clarify the challenges of detecting that somebody is in your community to start out with, so you may head them off earlier than it goes flawed.

There’s Peter Mackenzie from our Incident Response Workforce, who will let you know some fascinating, scary, however very academic tales about attackers that he’s been despatched into bat in opposition to.

And we wrap all of it up with Craig Jones, who will let you know arrange a SecOps staff of your individual.

Craig is the Senior Director of Safety Operations *at Sophos itself*, Doug, so he does cybersecurity in a cybersecurity firm.

He’s a stunning chap, and properly value listening to.

DOUG. Can’t wait… I shall be there!

Please be part of me, everybody – will probably be a rollicking good time.

And talking of a rollicking good time, it’s time for our This Week in Tech Historical past section.

One thing that’s close to and expensive to my coronary heart – this week, on 23 September 2008, the world’s first Android telephone was launched.

It was known as the T-Cellular G1, and it featured a 3.2-inch flip-out display that exposed a full {hardware} keyboard.

It additionally had a trackball and no commonplace headphone jack.

Early opinions have been combined, however hopeful.

Due to Android’s comparatively open nature, G1 went on to promote one million handsets in six months, and at one level accounted for two-thirds of gadgets on T-Cellular’s 3G community.

I had a type of gadgets… it was one among my favourite telephones of all time.

DUCK. Aaaaah, trackballs on telephones, eh?

Bear in mind the BlackBerries?

It was the factor, wasn’t it… that trackball was actually nice.

DOUG. It was good for scrolling.

DUCK. Then they went, “Out with shifting elements,” and it was an infrared sensor or one thing.

DOUG. Sure.

DUCK. How instances change, Doug.

DOUG. Sure… I miss it.

DUCK. Such as you, I favored these slide-out keyboards that the early telephones had.

There’s one thing reassuring about really listening to the click-click-click.

I believe what I actually favored about it’s that if you popped out the keyboard, it didn’t obscure half the display.

DOUG. Precisely!

DUCK. It wasn’t like half the e-mail you’re studying disappeared if you needed to answer.

Which I assume we’ve simply received used to now… that’s the way in which of the world, I suppose.

DOUG. That was a very long time in the past – less complicated instances.

Let’s speak in regards to the Firefox 105 launch.

What’s new from a safety standpoint right here, Paul?

DUCK. Fortuitously, nothing that seems to be within the wild and nothing that charges a vital stage of vulnerability.

However there are just a few intriguing vulnerabilities.

One through which a person internet web page that’s cut up right into a bunch of separate IFRAMES may have safety permission leakage between these elements.

So, you might need a less-privileged body from a subdomain in your website, for instance, that isn’t supposed to have the ability to entry the webcam (as a result of this bug is about system permissions), but it seems as if you would possibly really give you the chance to take action.

And one other related sounding bug, the place a subdomain of your web site – a weblog or a microsite or one thing like that – may really mess with cookies within the father or mother website.

Oh, and a very good previous “stack buffer overflow when initialising graphics”… only a reminder that reminiscence bugs are nonetheless an issue!

And naturally, there’s the standard “reminiscence security bugs fastened in Firefox 105”, and within the Prolonged Help Launch, which is 102.3.

Do not forget that within the Prolonged Help Launch, the 2 numbers add collectively: 102+3 = 105.

So, the Prolonged Help Launch is all the things from the principle model quantity, plus three updates value of safety fixes, however with the characteristic fixes held again.

So get it whereas it’s contemporary.

DOUG. Please do!

Let’s transfer on to the story of the century, breathlessly reported: “Uber has been hacked.”

Wanting a little bit nearer at it… sure, it’s dangerous, it’s embarrassing, however it may have been a lot, a lot worse.

DUCK. Sure, Uber has come out with a comply with up report, and it appears that evidently they’re suggesting {that a} hacking group like LAPSUS$ was accountable.

We’ve spoken about LAPSUS$ on the podcast earlier than.

It’s a form of a “let’s do it for the lulz” type of factor, the place it doesn’t look as if they’re really after promoting the information, though they could give it away free of charge or actually embarrass the corporate with it.

As I say, the embarrassment comes from the obvious extent of the breach, happily, slightly than its depth.

It looks like the attackers needed to wander round via the community as rapidly as attainable, grabbing screenshots, saying, “Hey, look, right here’s me in all types of issues”…

…together with Slack workspaces; Uber’s risk safety software program (in previous language, the anti-virus); an AWS console; firm journey and bills.

There was a screenshot that I noticed revealed that confirmed who’d put within the greatest T&E [travel and expenses] claims in latest instances. [LAUGHTER]

We snigger, however there are worker names in there, in order that’s a foul look as a result of it’s implying that the individual may have gotten at worker knowledge.

A vSphere digital server console; Google workspaces; and the place the place it appears the hacker really put within the “UBER HAS BEEN HACKED” in capital letters that made the headlines (it even made the Bare Safety headline).

Apparently that was posted to… (oh, expensive, Doug [LAUGHS] – it’s not humorous, but it’s)

…to Uber’s personal bug bounty service, which is a really embarrassing look.

DOUG. It seems like somebody received a maintain of an Uber polo shirt and put it on, and sweet-talked their well beyond the reception desk saying, “Oh, my badge isn’t working,” or one thing, received into the headquarters after which simply began taking footage of stuff.

Then they wrote on the bulletin board within the worker break room that they’ve been hacked.

It seems like this individual may have been an Preliminary Entry Dealer [jargon term for hacker who steals passwords and sells them on] in the event that they actually needed to.

They might have performed so many extra dangerous issues whereas they have been in there.

However they simply took footage, and it was a humiliation to Uber.

DUCK. Sure.

I believe the important thing element that we may add to your analogy of “getting via the principle safety checkpoint” is that, on the way in which in, it additionally appears that they have been capable of attain into the super-secure secret cupboard the place the access-all-areas passes are stored, and purloin one.

DOUG. Sure. [LAUGHS]

DUCK. In different phrases, they discovered a password in a PowerShell script, on an brazenly seen community share…

…in order that they solely wanted low stage entry, and that allowed them to get into what was basically the password supervisor for Uber’s networks.

DOUG. Sure.

So it’s not that this wasn’t unavoidable.

If we get to the recommendation in your article right here, we have now a number of issues that Uber may have performed otherwise.

Beginning with: “Password managers and two-factor authentication aren’t a panacea.”

Simply because you may have these… that’s a safety gate, however it’s not the end-all and be-all to maintaining somebody out.

DUCK. Completely.

We’ll be speaking in regards to the LastPass breach in a minute, the place it appears that evidently the attackers didn’t really must hassle with the 2FA facet of issues.

They simply waited till the consumer that they have been shadowing had gone via that train themselves, after which “borrowed their move”.

So, certainly, 2FA doesn’t imply, “Oh, now I don’t have to fret about outsiders getting in.”

It does make that preliminary entry a bit more durable, and should make the social engineering extra sophisticated and extra more likely to stand out.

However as you say, it’s an extra safety gate.

DOUG. And the following one, on the identical be aware, is: “When you’re in, you may’t simply let individuals wander round.”

Safety belongs all over the place within the community, not simply on the edge.

DUCK. Do I hear you saying the phrases Zero Belief, Douglas?

DOUG. [LAUGHS] I used to be going to…

DUCK. I do know that seems like a little bit of a gross sales schpiel, and (shock, shock) Sophos has a Zero Belief Community Entry product.

However we have now that product as a result of I believe it’s one thing that’s demanded by the way in which that trendy networks function, so that you simply solely get the entry you really want for the duty in hand.

And, if you concentrate on it, that doesn’t simply profit the corporate that’s dividing up its community.

It’s additionally good for customers, as a result of it means they will’t make unlucky blunders though they assume they’re making an attempt to do the fitting factor.

DOUG. And we additionally discuss: “Common cybersecurity measurement and testing”.

When you’re not ready to do this in-house, contemplate hiring it out, since you want eyes on this across the clock.

DUCK. Sure.

Two cliches, if I’ll, Doug?

DOUG. You could. [LAUGHS]

DUCK. Cybersecurity is a journey, not a vacation spot.

You frequently need to revisit to verify [A] that you simply did accurately what you meant, and [B] that what you deliberate to do yesterday remains to be a legitimate and helpful defence in the present day.

And the thought of getting any individual that can assist you assessment what’s taking place, notably if you assume one thing dangerous has simply occurred, is it implies that you don’t find yourself with safety incidents being main distractions to your common IT and Safety Operations staff.

Distractions may really be intentionally seeded by the crooks to behave as a distraction for the assault that they’ve received deliberate for later…

DOUG. After which lastly, we spherical ited out with a few suggestions to your workers: “Arrange a cyber safety hotline to your workers to report incidents”, and belief them that can assist you out by reporting such incidents.

DUCK. Sure.

Lots of people have determined that persons are the largest downside.

I believe that’s the flawed method to take a look at it.

Individuals are, actually, top-of-the-line methods that you could discover issues that you simply didn’t anticipate.

It’s all the time the issues that you simply didn’t anticipate that can catch you out, as a result of for those who had anticipated them, you’ll in all probability have prevented them within the first place!

Take the objective of turning everybody in your organisation into eyes and ears to your personal safety staff.

DOUG. Excellent!

And we’ve received extra Uber protection.

Paul, you and Chester Wisniewski did a fantastic minisode, S3 Ep100.5.

Pure thunder, if I’ll.

It’s known as: Uber breach – An professional speaks.

You’ll be able to hear Paul and Chet speaking about this explicit breach in a little bit bit extra depth:

DUCK. I believe an important factor that got here out of that minisode of the podcast is what you alluded to earlier, “What if this had been an Preliminary Entry Dealer?”

In different phrases, in the event that they went in particularly to get the passwords and received out quietly.

This type of broad-but-shallow assault is definitely surprisingly frequent, and in lots of circumstances, as you instructed, the issue is that you simply don’t realise it’s occurred.

These crooks exit of their solution to hold as quiet as attainable, and the thought is that they take all these entry passwords, entry tokens, data they’ve received…

…and promote it on the darkweb for different crooks who wish to do very particular issues in particular elements of your community.

DOUG. All proper, we’ll keep on the breach prepare, however we’re simply going to change automobiles on the prepare.

We’re going to stroll throughout and watch out to not fall out onto the platform… however we’re going to get into the LastPass automobile.

They’ve received a put up mortem out.

They nonetheless don’t know the way the criminals received in, however at the least they admitted it.

And it looks like it wasn’t essentially for the lulz… thus related however totally different to the Uber breach.

DUCK. Certainly, it appears that evidently this one, you would possibly say, was deeper however narrower.

I believe the report is an effective instance of present data that’s really helpful after an assault.

As you say, they appear to have come out with data that makes it clear what they assume occurred.

They admitted to the “identified unknowns”.

For instance, they stated, “It seems as if the crooks implanted malware that was capable of masquerade as a developer who had already logged in with their password and 2FA code.”

They figured that out, however they don’t know the way that implant occurred within the first place, they usually have been respectable sufficient to say they didn’t know.

And I believe that’s fairly good, slightly than simply going, “Oh, properly, we’ve undoubtedly fastened all the issues and this gained’t occur once more.”

If I have been a LastPass consumer, it might make me extra inclined to consider the opposite issues that I’ve to depend on them to state…

…particularly that the event community the place their code was stolen is separate from their different networks, in order that the attackers weren’t capable of attain out and get issues like buyer knowledge or password hashes.

And I’m additionally inclined to simply accept LastPass’s clarification (as a result of they’re capable of justify it) that even when the crooks *had* been capable of soar from the developer community to the cloud storage elements of the community, and even when that they had been capable of run off with password hashes, it might have been very tough for them to do something with it.

As a result of LastPass merely doesn’t know your grasp password.

They usually have a little bit diagram that explains why they consider that to be the case.

So, I believe, if I have been a Final Move consumer, that I’d be inclined to consider them.

DOUG. I *am* a Final Move consumer, and I discovered this to be extra reassuring than not.

I wasn’t too fearful about this earlier than, and now I’m barely much less fearful, and definitely not fearful sufficient to dump it wholesale, change all my passwords, and that type of stuff.

So I assumed it was fairly good.

DUCK. Certainly, one of many issues that individuals got here out with once we first reported on this breach is, “Properly, the crooks received into the supply code management system. In the event that they have been capable of obtain all this mental property, what in the event that they have been capable of add some sneaky and unauthorised adjustments on the identical time?”

Perhaps they ran off with the code so they may promote the mental property, so industrial espionage was their major automobile…

…however what if there was a provide chain assault as properly?

And LastPass did try to reply that query by saying, “We’ve reviewed supply code adjustments and so far as we are able to see, the attackers weren’t capable of, or didn’t, make any.”

Additionally, they clarify how even when the crooks had made adjustments, there are checks and balances that forestall these adjustments simply flowing robotically into the software program that you simply would possibly obtain, or that their very own cloud providers would possibly use.

In different phrases, they’ve a bodily separation between the developer community and the manufacturing community, and a full-and-proper code assessment and testing course of is required every time for one thing basically to leap throughout that hole.

I discovered that reassuring.

They’ve taken precautions that make it much less probably {that a} provide chain assault within the improvement community may attain clients.

They usually seem to have gone out of their solution to confirm that no such adjustments have been made anyway.

DOUG. Alright, there’s extra on that on nakedsecurity.sophos.com, together with a hyperlink to the LastPass briefing itself.

Allow us to now flip to one among our listeners!

Bare Safety Podcast listener Jonas writes in…

…and that is an oldie-but-a-goodie.

I wouldn’t have believed this myself – I’ve heard this story earlier than in numerous contexts, and I really witnessed this as I used to be working as a pc technician again within the early 2000s.

It is a actual downside, and it occurs.

Jonas writes:

“In within the early Nineteen Nineties, our pc classroom had a variety of Apple Macintosh Classics with the three.5-inch floppy drives.

In these days, if you wanted to put in issues, you probably did so with a bunch of disks – Insert disk 1; Insert disk 2; and so forth.

Properly, one among my classmates took the set up directions too actually.

She began with the primary diskette, and after some time the set up course of instructed her to ‘Please insert disk 2’, and she or he did.”

Simply let that sit there for a little bit bit…

DUCK. [LAUGHS A BIT TOO LOUDLY] We shouldn’t snigger, eh?

The directions may have been clearer!

DOUG. Jonas continues:

“When retelling the story, she stated, ‘The second disk was a bit more durable to get in, however I managed to drive it in. However it nonetheless stored asking for the second disk.’

So she didn’t perceive why it nonetheless wanted disk 2 when she had already inserted disk 1 *and* disk 2… and it was fairly onerous to get the 2 disks out.

And even then, the floppy drive by no means labored once more on that Mac anyway.

It wanted to get replaced, however the entire class realized you wanted to take away the earlier disk earlier than inserting the following one.”

DUCK. Properly, there you may have it!

DOUG. I all the time keep in mind my days as a technician at CompUSA.

We had a counter.

Individuals would lug their desktop computer systems in, put the desktop up on the counter, and inform us what was flawed.

I noticed a buyer are available in and instantly noticed a diskette wedged within the 3.5-inch floppy drive, and I assumed. “Oh my God. I’ve heard this story. I’ve examine it on the web and I’m lastly experiencing it in actual life.”

It didn’t get all the way in which in, however they managed to midway jam a second diskette into the floppy drive, they usually couldn’t get it out.

So we needed to open the case of the pc, disconnect and unscrew the floppy drive, pull the floppy drive out of the entrance of the pc, after which it took a few us to dislodge that diskette.

And, after all, the disk drive had to get replaced…

Thanks very a lot, Jonas, for sending that in.

When you’ve got an fascinating story, remark or query you’d prefer to submit, we’d like to learn it on the podcast.

Thanks very a lot for listening.
