DOUG. Juicejacking, public psychotherapy, and Enjoyable with FORTRAN.
All that and extra on the Bare Safety podcast.
[MUSICAL MODEM]
Welcome to the podcast, all people.
I’m Doug Aamoth; he’s Paul Ducklin.
Paul, how do you do right this moment, Sir?
DUCK. I’m very nicely, Douglas.
I’m intrigued by your phrase “Enjoyable with FORTRAN”.
Now, I do know FORTRAN myself, and enjoyable just isn’t the primary adjective that springs to thoughts to explain it. [LAUGHS]
DOUG. Properly, you may say, “You possibly can’t spell ‘FORTRAN’ with out ‘enjoyable’.”
That’s not fairly correct, however…
DUCK. It’s really astonishingly *inaccurate*, Doug! [LAUGHS]
DOUG. [LAUGHING] Preserve that in thoughts, as a result of this has to do with inaccuracies.
This week, on 19 April 1957, the primary FORTRAN program ran.
FORTRAN simplified programming, starting with a program run at Westinghouse that threw an error on its first try – it produced a “lacking comma” diagnostic.
However the second try was profitable.
How do you want that?
DUCK. That’s fascinating, Doug, as a result of my very own – what I at all times thought was ‘data’, however seems could be an city legend…
…my very own story about FORTRAN comes from about 5 years after that: the launch of the Mariner 1 house probe.
Spacecraft don’t at all times comply with precisely the place they’re purported to go, and so they’re purported to right themselves.
Now, you think about the type of calculations concerned – that was fairly onerous within the Sixties.
And I used to be advised this semi-officially (that means, “I heard it from a lecturer at college once I was learning laptop science, but it surely wasn’t a part of the syllabus”)…
..apparently, that bug was all the way down to a line in FORTRAN that was purported to say DO 51 I = 1,100, which is a “for loop”.
It says, “Do 100 loops, as much as and together with line 51.”
However the particular person typed DO 51 I = 1.100, with a dot, not a comma.
FORTRAN ignores areas, so it interpreted DO51I = as a variable project, assigned that variable the worth 1.100, after which went around the loop as soon as… as a result of it hadn’t been advised to loop at line 51, and line 51 simply executed as soon as.
I at all times assumed that that was the correction loop – it was purported to have 100 goes to get the spacecraft again on the right track, and it solely had one go, and due to this fact it didn’t work.
[LAUGHS]
And it appears it could not really be true… could also be a little bit of an city legend.
As a result of there’s one other story that claims that truly the bug was all the way down to an issue within the specs, the place somebody wrote out the equations that wanted to be coded.
And for one of many variables, they stated, “Use the present worth of this variable”, when the truth is, you had been purported to clean the worth of that variable by averaging it over earlier readings.
You possibly can think about why that may toss stuff off track if it needed to do with course correction.
So I don’t know which is true, however I just like the DO 51 I = 1,100 story, and I plan to maintain eating out on it for so long as I can, Doug.
DOUG. [LAUGHS] Like I stated, “Enjoyable with FORTRAN”.
DUCK. OK, I take your level, Doug.
DUCK. Each these tales are enjoyable…
One thing not so enjoyable – an update to an update to an update.
I imagine that is a minimum of the third time we’ve talked about this story, however that is the psychotherapy clinic in Finland that housed all its affected person knowledge, together with notes from periods, on-line within the cloud beneath a default password, which was leveraged by evildoers.
These evildoers tried to get some cash out of the corporate.
And when the corporate stated no, they went after the sufferers.
Ex-CEO of breached pyschotherapy clinic gets prison sentence for bad data security
DUCK. How terrible should which have been, eh?
As a result of it wasn’t simply that that they had the sufferers’ ID numbers and monetary particulars for a way they paid for his or her remedy.
And it wasn’t simply that that they had some notes… apparently, the periods had been recorded and transcribed, and *these* had been uploaded.
So that they principally had all the things you’d stated to your therapist…
…and one wonders whether or not you had any concept that your phrases could be preserved without end.
Might need been within the small print someplace.
Anyway, as you say, that’s what occurred.
The blackmailer went after the corporate for, what, €450,000 (which was about half 1,000,000 US {dollars} on the time), and so they weren’t inclined to pay up.
So that they thought, “Hey, why don’t I simply contact all of the sufferers? As a result of I’ve received all their contact particulars, *and* I’ve received all their deepest, darkest secrets and techniques and fears.”
The criminal figured, “I can contact them and say, ‘You’ve received 24 hours to pay me €200; then I’ll provide you with 48 hours to pay me €500; after which I’m going to doxx you – I’m going to dump your knowledge for everyone to see’.”
And I did learn one article that steered that when the sufferers didn’t give you the cash, he really discovered individuals who’d been talked about of their conversations.
DOUG. Didn’t somebody’s mom get roped into this, or one thing like that?
DUCK. Sure!
They stated, “Hey, we have now conversations together with your son; we’re going to dump all the things that he stated about you, from a personal session.”
Anyway, the excellent news is that the victims determined they had been positively not going to take this mendacity down.
And a great deal of them did report it to the Finnish police, and that gave them impetus to take this as a critical case.
And the investigations have been ongoing ever since.
There’s any individual… I imagine he’s nonetheless in custody in Finland; he hasn’t completed his trial but for the extortion facet.
However in addition they determined, “You recognize what, the CEO of the corporate that was so shabby with the info ought to bear some private legal responsibility.”
He can’t simply go, “Oh, it was the corporate; we’ll pay a wonderful” (which they did, and in the end went bankrupt).
That’s not sufficient – he’s purported to be the boss of this firm; he’s purported to set the requirements and decide how they function.
So he went to trial as nicely.
And he’s simply been discovered responsible and given a 3 month jail sentence, albeit a suspended one.
So if he retains his nostril clear, he can keep out of jail… however he did get taken to activity for this in courtroom, and given a felony conviction.
As mild because the sentence may sound, that does sound like a great begin, doesn’t it?
DOUG. Quite a lot of feedback on this put up are saying they need to power him to go to jail; he ought to really spend time in jail.
However one of many commenters, I believe rightly, factors out that that is widespread for first-time offenders for non-violent crimes…
…and he does now have a felony document, so he might by no means work on this city once more, because it had been.
DUCK. Sure, and maybe extra importantly, it would give anyone pause earlier than permitting him the authority to make this type of poor determination in future.
As a result of plainly it wasn’t simply that he allowed his IT staff to do shabby work or to chop corners.
Evidently they did know they’d been breached on two events, I believe in 2018 and 2019, and determined, “Properly, if we don’t say something, we’ll get away with it.”
After which in 2020, clearly, a criminal received maintain of the info and abused it in a approach that you simply couldn’t actually doubt the place it got here from.
It wasn’t simply, “Oh, I’m wondering the place they received my electronic mail tackle and nationwide id quantity?”
You possibly can solely get your Clinic X non-public psychotherapy transcript from Clinic X, you’d count on!
DOUG. Sure.
DUCK. So there’s additionally the facet that in the event that they’d come clear in 2018; in the event that they’d disclosed the breach as they had been purported to, then…
(A) They’d have executed the correct factor by the legislation.
(B) They’d have executed the correct factor by their sufferers, who might have began taking precautions upfront.
And (C), they’d have had some compunction upon them to go and repair the holes as a substitute of going, “Oh, let’s simply preserve quiet about it, as a result of if we declare we didn’t know, then we don’t must do something and we might simply keep it up within the shabby approach that we have now already.”
It was positively not thought-about an harmless mistake.
And due to this fact, in the case of cybercrime and knowledge breaches, it’s doable to be each a sufferer and a perpetrator on the similar time.
DOUG. A superb level nicely put!
Let’s transfer on.
Again in February 2023, we talked about rogue 2FA apps within the app shops, and the way typically they simply type of linger.
And linger they’ve.
Paul, you’re going to be doing a stay demo of how certainly one of these well-liked apps works, so everybody can see… and it’s nonetheless there, proper?
Beware rogue 2FA apps in App Store and Google Play – don’t get hacked!
DUCK. It’s.
Sadly, the podcast will come out simply after the demo has been executed, however that is some analysis that was executed by a pair of impartial Apple builders, Tommy Mysk and Talal Haj Bakry.
On Twitter, you’ll find them as @mysk_co.
They commonly look into cybersecurity stuff in order that they will get cybersecurity proper of their specialist coding.
They’re programmers after my very own coronary heart, as a result of they don’t simply do sufficient to get the job executed, they do greater than sufficient to get the job executed nicely.
And this was across the time, if you happen to keep in mind, that Twitter had stated, “Hey, we’re going to be discontinuing SMS-based two-factor authentication. Subsequently, if you happen to’re counting on that, you’ll need to go and get a 2FA app. We’ll depart it to you to seek out one; there are masses.”
Twitter tells users: Pay up if you want to keep using insecure 2FA
Now, if you happen to simply went to the App Retailer or to Google Play and typed in Authenticator App, you bought so many hits, how would you recognize which one to decide on?
And on each shops, I imagine, the highest ones turned out to be rogues.
Within the case of the highest search app (a minimum of on the Apple Retailer, and a number of the top-ish apps on Google Play), it seems that the app builders had determined that, with a view to monitor their apps, they’d use Google Analytics to document how folks use the apps – telemetry, because it’s known as.
A lot of apps do that.
However these builders had been both sneakily malicious, or so ignorant or careless, that in amongst the stuff they collected about how the app was behaving, in addition they took a replica of the two-factor authentication seed that’s used to generate all of the codes for that account!
Principally, that they had the keys to all people’s 2FA castles… all, apparently innocently, by program analytics.
However there it was.
They’re amassing knowledge that completely ought to by no means depart the cellphone.
The grasp key to each six-digit code that comes each 30 seconds, for evermore, for each account in your cellphone.
How about that, Doug?
DOUG. Sounds dangerous.
Properly, we will probably be trying ahead to the presentation.
We’ll dig up the recording, and get it out to folks on subsequent week’s podcast… I’m excited!
Alright, shifting proper alongside to our ultimate subject, we’re speaking about juicejacking.
It’s been some time… been about over ten years since we first heard this time period.
And I’ve to confess, Paul, once I began studying this, I started to roll my eyes, after which I ended, as a result of, “Why are the FBI and the FCC issuing a warning about juicejacking? This have to be one thing massive.”
However their recommendation just isn’t making an entire lot of sense.
One thing have to be happening, but it surely doesn’t appear that massive a deal on the similar time.
FBI and FCC warn about “Juicejacking” – but just how useful is their advice?
DUCK. I believe I’d agree with that, Doug, and that’s why I used to be minded to put in writing this up.
The FCC… for many who aren’t in the US, that’s the Federal Communications Fee, so in the case of issues like cellular networks, you’d suppose they know their oats.
And the FBI, in fact, are primarily the federal police.
So, as you say, this turned an enormous story.
It received traction all around the world.
It was actually repeated in lots of media retailers within the UK: [DRAMATIC VOICE] “Beware charging stations at airports.”
As you say, it did seem to be slightly little bit of a blast from the previous.
I wasn’t conscious why it will be a transparent and current “large consumer-level hazard” proper now.
I believe it was 2011 that it was a time period coined to explain the concept that a rogue charging station may simply not present energy.
It might need a hidden laptop on the different finish of the cable, or on the different facet of the socket, that attempted to mount your cellphone as a tool (for instance, as a media machine), and suck information off it with out you realising, all beneath the guise of simply offering you with 5 volts DC.
And it does appear as if this was only a warning, as a result of typically it pays to repeat previous warnings.
My very own checks steered that the mitigation nonetheless works that Apple put in place proper again in 2011, when juicejacking was first demonstrated on the Black Hat 2011 convention.
While you plug in a tool for the primary time, you’re supplied the selection Belief/Do not Belief.
So there are two issues right here.
Firstly, you do must intervene.
And secondly, in case your cellphone’s locked, any individual can’t get on the Belief/Do not Belief button secretly by simply reaching over and tapping the button for you.
On Android, I discovered one thing comparable.
While you plug in a tool, it begins charging, however you need to go into the Settings menu, enter the USB connection part, and change from No Information mode into both “share my photos” or “share all my information” mode.
There’s a slight warning for iPhone customers whenever you plug itinto a Mac.
In the event you do hit Belief by mistake, you do have the issue that in future, whenever you plug it in, even when the cellphone is locked, your Mac will work together together with your cellphone behind your again, so it doesn’t require you to unlock the cellphone.
And the flip facet to that, that I believe listeners ought to concentrate on is, on an iPhone, and I think about this a bug (others may simply say, “Oh no, that’s an opinion. It’s subjective. Bugs can solely be goal errors”)…
…there is no such thing as a solution to assessment the checklist of gadgets you have got trusted earlier than, and delete particular person gadgets from the checklist.
Someway, Apple expects you to recollect all of the gadgets you’ve trusted, and if you wish to mistrust *one* of them, you need to go in and principally reset the privateness settings in your cellphone and mistrust *all* of them.
And, additionally, that possibility is buried, Doug, and I’ll learn it out right here since you in all probability received’t discover it by your self. [LAUGHS]
It’s beneath Settings > Normal > Switch or Reset iPhone > Reset Location and Privateness.
And the heading says “Put together for New iPhone”.
So the implication is you’ll solely ever want to make use of this whenever you’re shifting from one iPhone to the subsequent.
Nevertheless it does appear, certainly, as you stated on the outset, Doug, with juicejacking, that there’s a chance that somebody has a zero-day meaning plugging into an untrusted or unknown laptop might put you in danger.
DOUG. I’m making an attempt to think about what it will entail to usurp certainly one of these machines.
It’s this massive, garbage-can dimension machine; you’d must crack into the housing.
This isn’t like an ATM skimmer the place you’ll be able to simply match one thing over.
I don’t know what’s happening right here that we’re getting this warning, but it surely looks like it will be so onerous to really get one thing like this to work.
However, that being stated, we do have some recommendation: Keep away from unknown charging connectors or cables if you happen to can.
That’s a great one.
DUCK. Even a charging station that was arrange in completely good religion may not have the decency of voltage regulation that you desire to.
And, as a flip facet to that, I might counsel that in case you are on the street and also you understand, “Oh, I instantly want a charger, I don’t have my very own charger with me”, be very cautious of pound-shop or dollar-shop super-cheap chargers.
If you wish to know why, go to YouTube and seek for a fellow known as Huge Clive.
He buys low cost digital gadgets like this, takes them aside, analyses the circuitry and makes a video.
He’s received a improbable video a couple of knockoff Apple charger…
…[a counterfeit] that appears like an Apple USB charger, that he purchased for £1 in a pound-shop in Scotland.
And when he takes it aside, be ready to be shocked.
He additionally prints out the producer’s circuit diagram, and he really goes by with a sharpie and places it beneath his digicam.
“There’s a fuse resistor; they didn’t embody that; they left that out [crosses out missing component].”
“Right here’s a protecting circuit; they omitted all these elements [crosses more out].”
And ultimately he’s all the way down to about half the elements that the producer claimed had been within the machine.
There’s some extent the place there’s a spot between the mains voltage (which within the UK could be 230 volts AC at 50 Hz) and a hint on the circuit board that may be on the supply voltage (which for USB is 5 volts)…
…and that hole, Doug, might be a fraction of a millimetre.
How about that?
So, sure, keep away from unknown connectors.
DOUG. Nice recommendation.
DUCK. Carry your individual connectors!
DOUG. This can be a good one, particularly if you happen to’re on the run and you could cost rapidly, except for the safety implications: Lock or flip off your cellphone earlier than connecting it to a charger or laptop.
In the event you flip off your cellphone, it’ll cost a lot quicker, in order that’s one thing proper there!
DUCK. It additionally ensures that in case your cellphone does get stolen… which you may argue is a little more seemingly at certainly one of these multi-user charging stations, isn’t it?
DOUG. Sure!
DUCK. It additionally signifies that if you happen to do plug it in and a Belief immediate does pop up, it’s not simply sitting there for another person to go, “Ha, that appears like enjoyable,”and clicking the button you didn’t count on.
DOUG. Alright, after which we’ve received: Take into account untrusting all gadgets in your iPhone earlier than risking an unknown laptop or charger.
That’s the setting you simply walked by earlier beneath Settings > Normal > Switch or Reset iPhone…
DUCK. Walked *down* into; approach down into the pit of darkness. [LAUGHS]
You don’t *want* to do this (and it’s a little bit of a ache), but it surely does imply that you simply aren’t risking compounding a belief error that you will have made earlier than.
Some folks may think about that overkill, but it surely’s not, “It’s essential to do that”, merely a good suggestion as a result of will get you again to sq. one.
DOUG. And final however not least: Take into account buying a power-only USB cable or adapter socket.
These can be found, and so they simply cost, they don’t switch knowledge.
DUCK. Sure, I’m undecided whether or not such a cable is offered within the USB-C format, but it surely’s simple to get them in USB-A.
You possibly can really peer into the socket, and if it’s lacking the 2 center connectors… I put an image within the article on Bare Safety of a motorcycle mild I’ve that solely has the outer connectors.
In the event you can solely see energy connectors, then there’s no approach for knowledge to be transferred.
DOUG. Alright, superb.
And allow us to hear from certainly one of our readers… one thing of a counterpoint on the juicejacking piece.
Bare Safety Reader NotConcerned writes, partially:
This text comes off a bit naive. In fact, juicejacking isn’t some widespread downside, however to low cost any warning primarily based on a really primary take a look at of connecting telephones to a Home windows and Mac PC and getting a immediate is type of foolish. That doesn’t show there aren’t strategies with zero clicks or faucets wanted.
What say you, Paul?
DUCK. [SLIGHT SIGH] I get the purpose.
There might be an 0-day meaning whenever you plug it in at a charging station, there could be a approach for some fashions of cellphone, some variations of working system, some configurations… the place it might in some way magically bypass the Belief immediate or robotically set your Android into PTP mode or File Switch mode as a substitute of No Information mode.
It’s not unimaginable.
However if you happen to’re going to incorporate in all probability esoteric million-dollar zero-days within the checklist of issues that organisations just like the FCC and the FBI make blanket warnings about, then they need to be warning, day after day after day: “Don’t use your cellphone; don’t use your browser; don’t use your laptop computer; don’t use your Wi-Fi; don’t press something in any respect”, in my view.
So I believe what worries me about this warning just isn’t that you must ignore it.
(I believe that the element that we put within the article and the guidelines that we simply went by counsel that we do take it greater than severely sufficient – we’ve received some respectable recommendation in there which you can comply with in order for you.)
What worries me about this type of warning is that it was offered as such a transparent and current hazard, and picked up all all over the world so that it sort-of implies to folks, “Oh, nicely, that signifies that once I’m on the street, all I have to do is don’t plug my cellphone into humorous locations and I’ll be OK.”
Whereas, the truth is, there are in all probability 99 different issues that may provide you with much more security and safety if you happen to had been to do these.
And also you’re in all probability not at a big threat, in case you are wanting juice, and you actually *do* have to recharge your cellphone since you suppose, “What if I can’t make an emergency name?”
DOUG. Alright, wonderful.
Properly, thanks, NotConcerned, for writing that in.
DUCK. [DEADPAN] I presume that identify was an irony?
DOUG. [LAUGHS] I believe so.
In case you have an attention-grabbing story, remark or query you’d wish to submit, we’d like to learn it on the podcast.
You possibly can electronic mail ideas@sophos.com, you’ll be able to touch upon any certainly one of our articles, or you’ll be able to hit us up on social: @nakedsecurity.
That’s our present for right this moment; thanks very a lot for listening.
For Paul Ducklin, I’m Doug Aamoth, reminding you, till subsequent time, to…
BOTH. Keep safe!
