DOUG. Crackdowns, zero-days and Tik Tok porn.
All that, and extra, on the Bare Safety podcast.
[MUSICAL MODEM]
Welcome to the podcast, everyone.
I’m Doug Aamoth; he’s Paul Ducklin.
Paul, please excuse my voice.
I’m sickly, however I really feel mentally sharp!
DUCK. Wonderful, Doug.
Now, I hope you had an excellent week off, and I hope you probably did some nice Black Fridaying.
DOUG. I’ve too many youngsters to do something pleasant… they’re too younger.
However we received a few issues on Black Friday over the web.
As a result of, I don’t know, I can’t bear in mind the final time I’ve been to a retail retailer, however certainly one of lately I’ll make my manner again.
DUCK. I assumed you had been over Black Friday, ever since you bought thwarted for a Nintendo Wii again within the 18th century, Doug?
DOUG. That’s true, sure.
That was waddling as much as the entrance of the road and a few girls saying, “You want a ticket”, seeing how lengthy the road was and saying, “OK, this isn’t for me.”
DUCK. [LAUGHS] The ticket was presumably simply to get *into* the queue… you then’d discover out whether or not they truly had any left.
DOUG. Sure, they usually didn’t… spoiler!
DUCK. “Sir is just becoming a member of the pre-queue.”
DOUG. Sure.
So I didn’t really feel like combating a bunch of individuals.
All these photographs you see on the information… that may by no means be me.
We like to start out the present with This Week in Tech Historical past phase, and we’ve got a double function this week, Paul.
On 28 November 1948, the Polaroid Land Digital camera Mannequin 95 went on sale on the Jordan Marsh division retailer proper right here in Boston.
It was the primary business instantaneous digicam, again in 1948.
After which someday (and a number of other years) later, 29 November 1972, Atari launched its first product, a little bit recreation referred to as PONG.
DUCK. Whenever you introduced your intention to announce the Land Digital camera as Tech Historical past, I assumed… “It was 1968”.
Possibly a little bit bit earlier – perhaps within the late Fifties, a form of “Sputnik period” sort of factor.
1948, eh?
Wow!
Nice miniaturisation for that point.
When you consider how massive computer systems nonetheless had been, it wasn’t simply that they wanted rooms, they wanted their very own giant buildings!
And right here was this nearly magical digicam – chemistry in your hand.
My brother had a type of once I was a little bit child, and I bear in mind being completely amazed by it.
However not as amazed, Doug, as he was when he discovered that I had taken a few footage redundantly, simply to see the way it labored.
As a result of, after all, he was paying for the movie [LAUGHTER].
Which isn’t fairly as low-cost because the movie in common cameras.
DOUG. No, sir!
Our first story is one other historical-type story.
This was the Christmas Tree worm in 1987, also referred to as CHRISTMA EXEC, which was written within the REXX scripting language:
REXX… I’d by no means heard of this earlier than.
It drew an ASCII-art Christmas tree and unfold by way of e-mail, inflicting large disruption to mainframes the world over, and was sort of a precursor to the I Love You virus which affected IBM PCs.
DUCK. I believe lots of people underestimated each the extent of IBM’s networks within the Nineteen Eighties, and the facility of the scripting languages obtainable, like REXX.
You write this system as simply plain previous textual content – you don’t want a compiler, it’s only a file.
And for those who title the filename eight characters, thus CHRISTMA, not CHRISTMAS (though you can *sort* CHRISTMAS, as a result of it could simply ignore the -S)…
…and for those who gave the filename the extension EXEC (so: CHRISTMA [space] EXEC), then whenever you typed the phrase “Christmas” on the command line, it could run.
It ought to have been a warning shot throughout all our bows, however I believe it was felt to be a little bit little bit of a flash within the pan.
Till a yr later…
…then got here the Web Worm, Doug, which after all attacked Unix methods and unfold far and huge:
And by then I believe all of us realised, “Uh-oh, this viruses-and-worms scene might prove fairly troublesome.”
So, sure, CHRISTMA EXEC… very, quite simple.
It did certainly put up a Christmas tree, and that was meant to be the distraction.
You regarded on the Christmas tree, so that you in all probability didn’t discover all of the little indicators on the backside of your IBM 3270 terminal displaying all of the system exercise, till you began receiving these Christmas Tree messages again from dozens of individuals.
[LAUGHTER]
And so it went, on and on and on.
“A really pleased Christmas and my finest needs for the following yr”, It stated, all in ASCII artwork, or maybe I ought to say EBCDIC artwork.
There’s a remark on the high of the supply code: “Let this EXEC run and luxuriate in your self”.
And a little bit additional down, there’s a word that claims: “Searching this file isn’t any enjoyable in any respect.”
Which clearly for those who’re not a programmer, is kind of true.
And beneath it says, “Simply sort Christmas from the command immediate.”
So, identical to fashionable macro malware that claims to the consumer, “Hey, macros are disabled, however to your ‘further security’ it’s worthwhile to flip them again on… why not click on the button? It’s a lot simpler that manner.”
35 years in the past [LAUGHS], malware writers had already discovered that for those who ask customers properly to do one thing that isn’t in any respect of their curiosity, a few of them, presumably a lot of them, will do it.
When you’d authorised it, it was in a position to learn your information, and since it might learn your information, it might get the listing of all of the individuals you usually corresponded with out of your so referred to as nicknames or NAMES file, and blasted itself out to all of them.
DOUG. I’m not saying I miss this time, however there was one thing oddly comforting, 20 years in the past, firing up Hotmail and seeing tons of of emails from those that had me of their contacts listing…
… and simply *understanding* that one thing was happening.
Like, “There’s a worm going round, clearly”, as a result of I’m getting only a deluge of emails from individuals right here.
DUCK. Folks you’d by no means heard from for a few years… out of the blue they’d be throughout your mailbox!
DOUG. OK, let’s transfer proper alongside to the brand new, to the fashionable day…
…and this TikTok “Invisible Problem”:
TikTok “Invisible Problem” porn malware places us all in danger
Which is mainly a filter on TikTok that you could apply that makes you appear invisible… so after all, the very first thing individuals did was, “Why don’t I take off all my garments and see if it actually makes me invisible?”
After which, after all, a bunch of scammers are like, “Let’s put out some faux software program that may ‘uninvisible’ bare individuals.”
Do I’ve that proper?
DUCK. Sure, sadly, Doug, that’s the lengthy and the in need of it.
And, sadly, that proved a really enticing lure to a big variety of individuals on-line.
You’re invited to affix this Discord channel to search out out extra… and to get going, properly, it’s important to just like the GitHub web page.
So it’s all this self-fulfilling prophecy….
DOUG. That a part of it’s (I hate to make use of the B-word [brilliant])… that facet of it’s nearly B-word-worthy since you’re legitimising this illegitimate mission, simply by everybody upvoting it.
.
DUCK. Completely!
“Upvote it first, and *then* we’ll inform you all about it, as a result of clearly it’s going to be nice, as a result of ‘free porn’.”
And the mission itself is all a pack of lies – it simply hyperlinks by way of to different repositories (and that’s fairly regular within the open supply supply-chain scene)… they appear to be reliable tasks, however they’re mainly clones of reliable tasks with one line modified that runs throughout set up.
Which is a giant purple flag, by the best way, that even when this didn’t have the sleazy ‘undress individuals who by no means supposed it’ porno theme in it.
You’ll be able to find yourself with reliable software program, genuinely put in off GitHub, however the strategy of doing the set up, satisfying all of the dependencies, fetching all of the bits you want… *that* course of is the factor that introduces the malware.
And that’s precisely what occurred right here.
There’s one line of obfuscated Python; whenever you deobfuscate it, it’s mainly a downloader that goes and fetches some extra Python, which is super-scrambulated so it’s by no means apparent what it does.
The concept is basically that the crooks get to put in no matter they like, as a result of that downloader goes to a web site that the crooks management, to allow them to put something they need up for obtain.
And it seems to be as if the first malware that the crooks needed to deploy (though they may have put in something) was a data-stealing Trojan primarily based on, I believe, a mission often known as WASP…
…which mainly goes after fascinating information in your laptop, notably together with issues like cryptocoin wallets, saved bank cards, and importantly (you’ve in all probability guessed the place that is going!) your Discord password, your Discord credentials.
And we all know why crooks love social media and instantaneous messaging passwords.
As a result of, once they get your password, they usually can attain out on to your folks, and your loved ones, and your work colleagues in a closed group…
…it’s a lot extra plausible that they need to get a significantly better success charge in luring in new victims than they do with spray-and-pray stuff corresponding to e-mail or SMS.
DOUG. OK, we are going to keep watch over that – it’s nonetheless creating.
However some excellent news, lastly: this “Cryptorom” rip-off, which is a crypto/romance rip-off…
…we’ve received some arrests, big-time arrests, proper?
Multimillion greenback CryptoRom rip-off websites seized, suspects arrested in US
DUCK. Sure.
This was introduced by the US Division of Justice [DOJ]: seven websites related to so-called Cryptorom scammers taken down.
And that report additionally hyperlinks to the truth that, I believe, 11 individuals had been lately arrested within the US.
Now, Cryptorom, that’s a reputation that SophosLabs researchers gave to this explicit cybercrime scheme as a result of, as you say, it marries the strategy utilized by romance scammers (i.e. look you up on a relationship web site, create a faux profile, change into buddies with you) with cryptocurrency scamming.
As a substitute of the “Hey, I would like you to fall in love with me; let’s get married; now ship me cash for the visa” sort of rip-off…
…the crooks go, “Effectively, perhaps we’re not going to change into an merchandise, however we’re nonetheless good pals. [DRAMATIC VOICE] Have I received an funding alternative for you!”
So it out of the blue feels prefer it’s coming from somebody you may belief.
It’s a rip-off that entails speaking you into putting in an off-market app, even when you’ve got an iPhone.
“It’s nonetheless in improvement; it’s so new; you’re so vital; you’re proper on the core of it. It’s nonetheless in improvement, so join the TestFlight, the Beta program.”
Or they’ll go, “Oh, we’re solely publishing it to individuals who be a part of our enterprise. So give us cell gadget administration (MDM) management over your telephone, after which you may set up this app. [SECRETIVE VOICE} And don’t tell anyone about it. It’s not going to be in the app store; you’re special.”
And, of course, the app looks like a cryptocurrency trading app, and it’s backed by sweet-looking graphs that just strangely keep going up, Doug.
Your investments never really go down… but it’s all a pack of lies.
And then, when you want your money out, well (typical Ponzi or pyramid-scheme trick), sometimes they’ll let you take out a little bit of money… you’re testing, so you withdraw a bit, and you get it back.
Of course, they’re just giving you the money that you already put in back, or some of it.
DOUG. [SAD] Sure.
DUCK. After which your investments are going up!
After which they’re throughout you: “Think about for those who haven’t withdrawn that cash? Why don’t you set that cash again in? Hey, we’ll even mortgage you some extra money; we’ll put one thing with you. And why not get your pals in? As a result of one thing massive is coming!”
So you set within the cash, and one thing massive occurs, like the value shoots up, and also you’re going, “Wow, I’m so glad I reinvested the cash that I withdrew!”
And also you’re nonetheless pondering, “The truth that I might have withdrawn it should imply these persons are reliable.”
In fact, they’re not – it’s only a greater pack of lies than it was at first.
After which, whenever you lastly suppose, “I’d higher money out”,, out of the blue there’s all kinds of bother.
“Effectively, there’s a tax,” Doug, “There’s a authorities withholding tax.”
And also you go, “OK, so I’m going to have 20% chopped off the highest.”
Then the story is, “Really, no, it’s not *technically* a withholding tax.” (Which is the place they only take the cash out of the sum and provide the relaxation)
“Really, your account is *frozen*, so the federal government can’t withhold the cash.”
It’s a must to pay within the tax… you then get the entire quantity again.
DOUG. [WINCING] Oh, God!
DUCK. You must odor a rat at this level… however they’re throughout you; they’re pressuring you; they’re weedling; if not weedling, they’re telling you, “Effectively, you can get into bother. The federal government could also be after you!”
Persons are placing within the 20% after which, as I wrote [in the article], I hope to not rudely: GAME OVER, INSERT COIN TO BEGIN NEW GAME.
Actually, it’s possible you’ll then get contacted afterwards by someone who simply miraculously, Doug, goes, “Hey, have you ever been scammed by Cryptorom scams? Effectively, I’m investigating, and I might help you get the cash again.”
It’s a horrible factor to be in, as a result of all of it begins with the “rom” [romance] half.
They’re not truly after romance, however they *are* after sufficient of a friendship that you just really feel you may belief them.
So that you’re truly stepping into one thing “particular” – that’s why your family and friends weren’t invited.
DOUG. We’ve talked about this story a number of occasions earlier than, together with the recommendation, which is within the article right here.
The dismount [main item] within the recommendation column is: Pay attention brazenly to your family and friends in the event that they attempt to warn you.
Psychological warfare, because it had been!
DUCK. Certainly.
And second-last can be one to recollect: Don’t be fooled since you go to a scammer’s web site and it seems to be identical to the actual deal.
You suppose, “Golly, might they actually afford to pay skilled net designers?”
However for those who take a look at how a lot cash these guys are making: [A] sure, they may, and [B] they don’t even actually need to.
There are many instruments on the market that construct high-quality, visually pleasant web sites with realtime graphs, realtime transactions, magical-looking, stunning net varieties…
DOUG. Precisely.
It’s truly actually onerous to make a *unhealthy* trying web site these days.
It’s a must to strive further onerous!
DUCK. It’ll have an HTTPS certificates; it’ll have a legitimate-enough-looking area title; and naturally, on this case, it’s coupled with an app *that your folks can’t try for you by downloading themselves* off the App Retailer and going, “What on earth had been you pondering?”
As a result of it’s a “secret particular app”, by way of “super-special” channels, that simply makes it simpler for the crooks to deceive you by trying greater than adequate.
So, take care, people!
DOUG. Take care!
And let’s stick with reference to crackdowns.
That is one other massive crackdown – this story is actually intriguing to me, so I’m to listen to the way you unravel it:
Voice-scamming web site “iSpoof” seized, 100s arrested in large crackdown
It is a voice scamming web site which was referred to as iSspoof… and I’m shocked that it was allowed to function.
This isn’t a darkweb web site, that is on the common net.
DUCK. I suppose if all of your web site is doing is, “We’ll give you Voice Over IP Companies [VoIP] with added cool worth that features establishing your individual calling numbers”…
…in the event that they’re not brazenly saying, “The first aim of that is to do cybercrime”, then there could also be no authorized obligation for the internet hosting firm to take the positioning down.
And in case you are internet hosting it your self, and you’re the criminal… I suppose it’s fairly troublesome.
It took a court docket order in the long run, acquired by the FBI, I imagine, and executed by the Division of Justice, to go and declare these domains and put up [a message saying] “This area has been seized.”
So it was fairly a prolonged operation, as I perceive, simply making an attempt to get behind this.
The issue right here is it made it very easy so that you can begin up a scamming service the place, whenever you name someone, their telephone would pop up with the title of their Excessive Road financial institution that they themselves had entered into their telephone contact listing, striagh off *the financial institution’s personal web site*.
As a result of, sadly, there may be little or no authentication within the Caller ID or Calling Line Identification protocol.
These numbers that pop up earlier than you reply the decision?
They’re no higher than hints, Doug.
However sadly, individuals take them as a sort of gospel fact: “It says it’s the financial institution. How might anyone forge that? It MUST be the financial institution calling me.”
Not essentially!
When you take a look at the variety of calls that had been positioned… what was it, three-and-a-half-million within the UK alone?
10 million all through Europe?
I believe it was three-and-a-half million calls they positioned; 350,000 of these had been answered after which lasted greater than a minute, which means that the individual was starting to imagine the entire spoofing.
So: “Switch funds to the unsuitable account”, or “Learn out your two-factor authentication code”, or “Allow us to assist you together with your technical downside – let’s begin by putting in TeamViewer”, or whateveritis.
And even being invited by the crooks: “Examine the quantity for those who don’t imagine me!”
DOUG. That leads us to a query that I had the entire time studying this text, and it dovetails properly with our reader remark for the week.
Reader Mahnn feedback, “The telcos ought to be getting a fair proportion of the blame for permitting spoofing on their community.”
So, in that spirit, Paul, is there something telcos can truly do to cease this?
DUCK. Intriguingly, the following commenter (thanks, John, for this remark!) stated, “I want you’d talked about two issues referred to as STIR and SHAKEN.”
These are American initiatives – since you guys love your backronyms, don’t you, just like the CAN-SPAM Act?
DOUG. We do!
DUCK. So, STIR is “safe phone id revisited”.
And SHAKEN apparently stands for (don’t shoot me, I’m simply the messenger, Doug!)… what’s it, “signature-based dealing with of asserted data utilizing tokens”.
So it’s mainly like saying, “We lastly received used to utilizing TLS/HTTPS for web sites.”
It’s not excellent, however at the least it offers some measure so you may confirm the certificates in order for you, and it stops simply anyone pretending to be anybody, anytime they like.
The issue is that these are simply initiatives, so far as I do know.
We’ve got the expertise to do that, at the least for web telephony…
…however take a look at how lengthy it took us to do one thing so simple as getting HTTPS on nearly all the web sites on the earth.
There was an enormous backlash towards it.
DOUG. Sure!
DUCK. And, paradoxically, it wasn’t coming from the service suppliers.
It was coming from individuals going, “Effectively, I run a small web site, so why ought to I’ve to hassle about this? Why ought to I’ve to care?”
So I believe it could be a few years but earlier than there may be any robust id related to incoming telephone calls…
DOUG. OK, so it might take some time, [WRYLY] however as you say, we’ve got chosen our acronyms, which is a vital first step.
So, we’ve received that out of the best way… and we’ll see if this takes form ultimately.
So thanks, Mahnn, 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.
You’ll be able to e-mail ideas@sophos.com, you may touch upon any certainly one of our articles, or you may hit us up on social: @NakedSecurity.
That’s our present for at this time; thanks very a lot for listening.
For Paul Ducklin, I’m Doug Aamoth, reminding you: Till subsequent time…
BOTH. Keep safe.
