DOUG. Patches galore, horrifying remedy periods, and case research in dangerous cybersecurity.
All that, and extra, on the Naked Security podcast.
[MUSICAL MODEM]
Welcome to the podcast, everyone.
I’m Doug Aamoth; he’s Paul Ducklin.
Paul, how do you do?
We’ve received an enormous present as we speak.
DUCK. Yes, let’s hope we get via all of them, Doug!
DOUG. Let us do our greatest!
We will begin, after all, with our Tech History phase…
..this week, on 02 November 1815, George Boole, was born in Lincolnshire, England.
Paul, TRUE or FALSE: Boole made a number of nice contributions to arithmetic, the knowledge age, and past?
IF you have got some context THEN I’ll gladly hearken to it ELSE we are able to transfer on.
DUCK. Well, Doug, let me simply say then, as a result of I ready one thing I may learn out…
…e wrote a really well-known scientific work entitled, and also you’ll see why I wrote it down [LAUGHS]:
An Investigation of the Laws of Thought on that are Founded the Mathematical Theories of Logic and Probability
DOUG. Rolls proper off the tongue!
DUCK. He was proper behind symbolic logic, and he influenced Augustus De Morgan. (People might know De Morgan’s legal guidelines.)
And DeMorgan was Ada Lovelace’s arithmetic tutor.
She took these grand concepts of symbolic logic and figured, “Hey, when we get programmable computers, this is going to change the world!”
And she was proper! [LAUGHS]
DOUG. Excellent.
Thank you very a lot, George Boole, might you relaxation in peace.
Paul, now we have a ton of updates to speak about this week, so if you happen to may replace us on all these updates…
Let’s begin with OpenSSL:
The OpenSSL safety replace story – how are you going to inform what wants fixing?
DUCK. Yes, it’s the one everybody’s been ready for.
OpenSSL do the precise reverse of Apple, who say completely nothing till the updates simply arrive. [LAUGHTER]
OpenSSL say, “Hey, we’re going to be releasing updates on XYZ date, so you might want to get ready. And the worst update in this batch will have the level…”
And this time they wrote CRITICAL in capital letters.
That doesn’t occur typically with OpenSSL, and, being a cryptographic library, at any time when they are saying, “Oh, golly, there’s a CRITICAL- level hole”, everybody thinks again to… what was it, 2014?
“Oh, no, it’s going to be as bad as Heartbleed all over again,” as a result of it may very well be, for all you realize:
Anatomy of an information leakage bug – the OpenSSL “Heartbleed” buffer overflow
So we had per week of ready, and worrying, and “What are we going to do?”
And on 01 November 2022, the updates truly dropped.
Let’s begin with the numbers: OpenSSL 1.1.1 goes to model S-for-Sierra, as a result of that makes use of letters to indicate the person updates.
And OpenSSL 3.0 goes to three.0.7:
OpenSSL patches are out – CRITICAL bug downgraded to HIGH, however patch anyway!
Now, the crucial replace… truly, it turned out that whereas investigating the primary replace, they discovered a second associated replace, so there are truly two of them… these solely apply to OpenSSL 3.0, to not 1.1.1.
So I’m not saying, “Don’t patch if you’ve got 1.1.1”, however it’s much less pressing, you might say.
And the silver lining is that the CRITICAL stage, all in capital letters, was downgraded to HIGH severity, as a result of it’s felt that the bugs, which relate to TLS certificates validation, can virtually definitely be used for denial-of-service, however are most likely going to be very laborious to show into distant code execution exploits.
There are buffer overflows, however they’re sort of restricted.
There are two bugs… let me simply give the numbers so you possibly can check with them.
There’s CVE 2022-3602, the place you possibly can overwrite 4 bytes of the stack: simply 4 bytes, half a 64-bit tackle.
Although you possibly can write something you need, the quantity of injury you are able to do might be, however not essentially, restricted to denial-of-service.
And the opposite bug is named CVE-2022-3786, and in that one you are able to do as massive a stack overflow as you want, apparently [LAUGHS]… that is fairly amusing.
But you possibly can solely write dots, hexdecimal 0x2E in ASCII.
So though you possibly can utterly corrupt the stack, there’s a restrict to how artistic you could be in any distant code execution exploit you try to dream up.
The different silver lining is that, usually talking… not in all circumstances, however normally, significantly for issues like net servers, the place folks is likely to be utilizing OpenSSL they usually’re panicking: “What if people can steal secrets from our web server like they could in the Heartbleed days?”
Most net servers don’t ask shoppers who’re connecting, guests, to supply a certificates to validate themselves.
They don’t care; anybody is welcome to go to.
But server sends the consumer a certificates so the consumer, if it needs, can decide, “Hey, I really am visiting Sophos”, or Microsoft, or no matter web site I believe it’s.
So it appears to be like as if the almost certainly method this will probably be exploited could be for rogue servers to crash shoppers, somewhat than the opposite method round.
And I believe you’ll agree that servers crashing shoppers is dangerous, and you might do dangerous issues with it: for instance, you might block any individual from getting updates, as a result of it retains failing time and again and time and again.
But it doesn’t look as possible that this bug may very well be exploited for any random particular person on the Internet simply to start out scanning all of your net servers and crashing them at will.
I don’t suppose that’s possible.
DOUG. We do have a reader remark right here: “I have no idea what I’m supposed to update. Chrome firefox windows. Help?”
You by no means know.., there are all these totally different flavours of SSL.
DUCK. The excellent news right here is that, though some Microsoft merchandise do use and embody their very own copy of OpenSSL, it’s my understanding that neither Chrome nor Firefox nor Edge use it.
So I believe the reply to the query is that though you by no means know, from a pure Windows, Chrome, Firefox, Edge perspective, I don’t suppose it’s essential fear about this one.
It’s if you happen to’re working servers, significantly Linux servers, the place your Linux distro comes with both or each variations of OpenSSL, or when you’ve got particular Windows merchandise you’ve put in that occur to come back together with OpenSSL… and the product will usually inform you if it does.
Or you possibly can go in search of libcrypto*.dll or libssl*.dll.
And a fantastic instance of that, Doug, is Nmap, the very well-known and really helpful community scanning instrument that a lot of Red Teams use.
That program comes not solely with OpenSSL 1.1.1, packaged together with itself, however with additionally OpenSSL 3.0, so far as I can see.
And each of them at present, no less than after I seemed final night time, are old-fashioned.
I shouldn’t say this, however…
DOUG. [INTERRPTS, LAUGHING] If I’m a Blue Team member…
DUCK. Exactly! EXACTLY! [LAUGHING]
If you’re a Blue Teamer making an attempt to guard your community and also you suppose, “Oh, the Red Team are going to be scanning like crazy, and they love their Nmap”, you have got a combating probability to counterhack!
[LOUD LAUGHTER]
DOUG. OK, we’ve received another updates to speak about: Chrome, Apple and SHA-3 updates.
Let’s begin with Chrome, which had an pressing zero-day repair, they usually patched it fairly rapidly…
…however they weren’t tremendous clear on what was happening:
DUCK. I don’t know whether or not three attorneys wrote these phrases, every including an additional stage of indirection, however you realize that Google have this bizarre method of speaking about zero-days, similar to Apple, the place they inform the *literal* reality:
Google is conscious of reviews that an exploit for this vulnerability, CVE-2022-3723, exists within the wild.
Which is type of two ranges of indirection away from saying, “It’s an 0-day, folks!”
Instead, it’s, “Someone wrote a report that says it exists, and then they told us about the report.”
I believe we are able to all agree it wants patching, and Google should agree, as a result of…
…to be truthful to them, they mounted it virtually instantly.
Ironically, they did an enormous safety repair on the very day that this bug was reported, which I believe was 25 October 2022, and Google had mounted it inside what, three days?
Two days, truly.
And Microsoft have themselves adopted up with a really clear report on their Edge launch notes: on the 31 October 2022, they launch an replace and it explicitly mentioned that it fixes the bug reported by Google and the Chromium group.
DOUG. OK, excellent.
I’m reticent to deliver this up, however are we secure to speak about Apple now?
Do now we have any extra readability on this Apple zero-day?
Updates to Apple’s zero-day replace story – iPhone and iPad customers learn this!
DUCK. Well, the crucial deal right here is once we wrote in regards to the replace that included iOS 16.1 and iPadOS 16, which truly turned out to be iPadOS 16.1 in any case…
…individuals are asking us, understandably, “What about iOS 15.7? Do I have to go to iOS 16 if I can? Or is there going to be a 15.7.1? Or have they dropped support for iOS 15 altogether, game over?”
And, lo and behold, as success would have it (I believe it the day after we recorded final week’s podcast [LAUGHS]), they all of the sudden despatched out a notification saying, “Hey, iOS 15.7.1 is out, and it fixes exactly the same holes that iOS 16.1 and iPadOS 16/16.1 did.”
So now we all know that if you happen to’re on iOS or iPadOS, you *can* follow model 15 if you would like, and there’s a 15.7.1 that it’s essential get.
But when you’ve got an older cellphone that doesn’t help iOS 16, then you definately positively have to get 15.7.1 as a result of that’s your solely option to repair the zero-day.
And we additionally appear to have happy ourselves that iOS and iPadOS now each have the identical code, with the identical fixes, they usually’re each on 16.1, regardless of the safety bulletins might have implied.
DOUG. Alright, nice job, everyone, we did it.
Great work… took a couple of days, however alright!
And final, however definitely not least in our replace tales…
…it appears like we maintain speaking about this, and maintain making an attempt to do the correct factor with cryptography, however our efforts aren’t all the time rewarded.
So, living proof, this new SHA-3 bug?
DUCK. Yes, this can be a little totally different from the OpenSSL bugs we simply talked about, as a result of, on this case, the issue is definitely within the SHA-3 cryptographic algorithm itself… in an implementation often known as XKCP, that’s X-ray, Kilo, Charlie, Papa.
And that’s, if you happen to like, the reference implementation by the very group that invented SHA-3, which was initially known as Keccak [pronounced ‘ketchak’, like ‘ketchup’].
It was permitted about ten years in the past, they usually determined, “Well, we’ll write a collection of standardised algorithms for all the cryptographic stuff that we do, including SHA-3, that people can use if they want.”
Unfortunately, it appears to be like as if their programming wasn’t fairly as cautious and as sturdy as their authentic cryptographic design, as a result of they made the identical type of bug that Chester and I spoke about a couple of months in the past in a product known as NetUSB:
So, within the code, they had been making an attempt to test: “Are you asking us to hash too much data?”
And the theoretical restrict was 4GB minus one byte, besides that they forgot that there are speculated to be 200 spare bytes on the finish.
So they had been speculated to test whether or not you had been making an attempt to hash greater than 4GB minus one bytes *minus 200 bytes*.
But they didn’t, and that triggered an integer overflow, which may trigger a buffer overflow, which may trigger both a denial-of-service.
Or, within the worst case, a possible distant code execution.
Or simply hash values computed incorrectly, which is all the time going to finish in tears as a result of you possibly can think about that both a superb file would possibly find yourself being condemned as dangerous, or a nasty file is likely to be misrecognised nearly as good.
DOUG. So if this can be a reference implementation, is that this one thing to panic about on a widespread foundation, or is it extra contained?
DUCK. I believe it’s extra contained, as a result of most merchandise, notably together with OpenSSL, luckily, don’t use the XKCP implementation.
But PHP *does* use the XKCP code, so that you both wish to be sure you have PHP 8.0.25 or later, or PHP 8.1.12 or later.
And the opposite complicated one is Python.
Now, Python 3.11, which is the newest, shifted to a model new implementation of SHA-3, which isn’t this one, in order that’s not susceptible.
Python 3.9 and three.10… some builds use OpenSSL, and a few use the XKCP implementation.
And we’ve received some code in our article, some Python code, that you need to use to find out which model your Python implementation is utilizing.
It does make a distinction: one could be reliably made to crash; the opposite can’t.
And Python 3.8 and earlier apparently does have this XKCP code in it.
So you’re going to both wish to put mitigations in your individual code to do the buffer size test appropriately your self, or to use any wanted updates after they come out.
DOUG. OK, excellent, we’ll control that.
And now we’re going to spherical out the present with two actually uplifting tales, beginning with what occurs when the very non-public and really private contents of hundreds of psychotherapy periods get leaked on-line…
DUCK. The backstory is what’s now an notorious, and in reality bankrupt, psychotherapy clinic.
They had an information breach, I imagine, in 2018, and one other one in 2019.
And it turned out that these intimate periods that folks had had with their psychotherapists, the place they revealed their deepest and presumably generally darkest secrets and techniques, and what they thought of their pals and their household…
…all these items that’s so private that you simply sort of hope it wouldn’t be recorded in any respect, however would simply be listened to and the fundamentals distilled.
But apparently the therapists would kind up detailed notes, after which retailer them for later.
Well, possibly that’s OK in the event that they’re going to retailer them correctly.
But sooner or later, I suppose, they’d the “rush to the cloud”.
These issues grew to become out there on the Internet, and allegedly there was a sort of ueberaccount whereby anyone may entry every part in the event that they knew the password.
And, apparently, it was a default.
Oh, expensive, how can folks nonetheless do that?
DOUG. Oof!
DUCK. So anyone may get in, and any individual did.
And the corporate didn’t actually appear to do a lot about it, so far as I can inform, and it wasn’t disclosed or reported…
…as a result of in the event that they’d acted rapidly, possibly regulation enforcement may have gotten concerned early and closed this complete factor down in time.
But it solely got here out within the wash in October 2020, apparently, when the problem of the breach may very well be denied now not.
Because any individual who had acquired the info, both the unique intruder or somebody who had purchased it on-line, you think about, began making an attempt to do blackmail with it.
And apparently they first tried to blackmail the corporate, saying, “Pay us”… I believe the quantity was someplace round half-a-million Euros.
“Pay us this lump sum in bitcoins and we’ll make the data go away.”
But, thwarted by the corporate, the particular person with the info then determined, “I know what, I’m going to blackmail each person of the tens of thousands in the database individually.”
DOUG. Oh, boy…
DUCK. So they began sending emails saying, “Hey, pay me €200 yourself, and I’ll make sure your data doesn’t get exposed.”
Anyway, evidently the info wasn’t launched… and looking for the silver lining on this, Doug: [A] the Finnish authorities have now issued an arrest warrant, and [B] they’re going to go after the CEO of the previous firm (as I mentioned, it’s now bankrupt), saying that though the corporate was a sufferer of crime, the corporate itself was to date under par in the way it handled the breach that it must face some sort of penalty.
They didn’t report the breach when it may need made an enormous distinction, they usually simply merely, given the character of the info that they know they’re holding… they only did every part too shabbily.
And this isn’t simply, “Oh, you could get a regulatory fine.”
Apparently he may resist twelve months in jail.
DOUG. OK, effectively that’s one thing!
But to not be outdone, we’ve received a case examine in cybersecurity ineptitude and a extremely, actually poor post-breach response with this “See Tickets” factor:
Online ticketing firm “See” pwned for two.5 years by attackers
DUCK. Yes, this can be a very massive ticketing firm… That’s “See”, S-E-E, not “C” as within the programming language.
[GROANING] This additionally looks as if such a comedy of errors, Doug…
DOUG. It’s actually breathtaking.
25 June 2019… by this date, we imagine that cybercriminals had implanted data-stealing malware on the checkout pages run by the corporate.
So this isn’t that individuals are being phished or tricked, as a result of while you went to take a look at, your information may have been siphoned.
DUCK. So that is “malware on the website”?
DOUG. Yes.
DUCK. That is fairly intimately linked together with your transaction, in actual time!
DOUG. The regular suspects, like title, tackle, zip code, however then your bank card quantity…
…so that you say, “OK, you got my number, but did they also…?”
And, sure, they’ve your expiration date, they usually have your CVV quantity, the little three-digit quantity that you simply kind in to just be sure you’re legit together with your bank card.
DUCK. Yes, since you’re not speculated to retailer that after you’ve accomplished the transaction…
DOUG. No, Sir!
DUCK. …however you have got it in reminiscence *when you’re doing the transaction*, out of necessity.
DOUG. And then virtually two years later, in April of 2021 (two years later!), See Tickets was alerted to exercise indicating potential unauthorised entry, [IRONIC] they usually sprung into motion.
DUCK. Oh, that’s like that SHEIN breach we spoke about a few weeks in the past, isn’t it?
Fashion model SHEIN fined $1.9m for mendacity about information breach
They came upon from any individual else… the bank card firm mentioned, “You know what, there are a whole lot of dodgy transactions that seem to go back to you.”
DOUG. They launch an investigation.
But they don’t truly shut down all of the stuff that’s happening till [DRAMATIC PAUSE] January of 2022!
DUCK. Eight and a half months later, isn’t it?
DOUG. Yes!
DUCK. So that was their menace response?
They had a 3rd social gathering forensics group, they’d all of the specialists in, and greater than *eight months* later they mentioned, “Hey, guess what guys, we think we’ve kicked the crooks out now”?
DOUG. Then they went on to say, in October 2022, that “We’re not certain your information was affected”, however they lastly notified prospects.
DUCK. So, as a substitute of claiming, “The crooks had malware on the server which aimed to steal everybody’s data, and we can’t tell whether they were successful or not”, in different phrases, “We were so bad at this that we can’t even tell how good the crooks were”…
…they really mentioned, “Oh, don’t worry, don’t worry, we weren’t able to prove that your data was stolen, so maybe it wasn’t”?
DOUG. “This thing that’s been going on for two-and-a-half years under our nose… we’re just not sure.”
OK, so the e-mail that See Tickets sends out to their prospects contains some recommendation, however it’s truly not likely recommendation relevant to this explicit state of affairs… [SOUNDING DEFEATED] which was ironic and terrible, however type of humorous.
DUCK. Yes.
Whilst I’d agree with their recommendation, and it’s effectively value bearing in mind, specifically: all the time test your monetary statements recurrently, and be careful for phishing emails that try to trick you into handing over your private information…
…you suppose they could have included a little bit of a mea culpa in there, and defined what *they* had been going to do in future to forestall what *did* occur, which neither of these issues may presumably have prevented, as a result of checking your statements solely exhibits you that you simply’ve been breached after it occurs, and there was no phishing on this case.
DOUG. So that raises a superb query.
The one {that a} reader brings up… and our remark right here on this little kerfuffle is that Naked Security reader Lawrence pretty asks: “I thought PCI compliance required safeguards on all this stuff. Were they never audited?”
DUCK. I don’t know the reply to that query…
But even when they had been compliant, and had been checked for compliance, that doesn’t imply that they couldn’t have gotten a malware an infection the day after the compliance test was performed.
The compliance test doesn’t contain an entire audit of completely every part on the community.
My analogy, which individuals within the UK will probably be aware of, is that when you’ve got a automotive within the UK, it has to have an annual security test.
And it’s very clear, while you go a take a look at, that *this isn’t a proof that the automotive is roadworthy*.
It’s handed the statutory assessments, which take a look at the plain stuff that if you happen to haven’t performed appropriately, means your automotive is *dangerously* unsafe and shouldn’t be on the highway, corresponding to “brakes do not work”, “one headlight is out”, that sort of factor.
Back when PCI DSS was first changing into a factor, a lot of folks criticised it, saying, “Oh man, it’s too little, too late.”
And the response was, “Well, you have to start somewhere.”
So it’s completely potential that they did have the PCI DSS tick of approval, however they nonetheless received breached.
And then they only didn’t discover… after which they didn’t reply in a short time… after which they didn’t ship a really significant e-mail to their prospects, both.
My private opinion is that if I had been a buyer of theirs, and I acquired an e-mail like that, given the size of time over which this had unfolded, I’d take into account that just about nonchalance.
And I don’t suppose I’d be finest happy!
DOUG. Alright, and I agree with you.
We’ll control that – the investigation remains to be ongoing, after all.
And thanks very a lot, Lawrence, for sending in that remark.
If you have got an fascinating story, remark or query you’d prefer to submit, we’d like to learn it on the podcast.
You can e-mail suggestions@sophos.com, or you possibly can touch upon any one in every of our articles, or you possibly can hit us up on social: @NakedSecurity.
That’s our present for as we speak; thanks very a lot for listening.
For Paul Ducklin, I’m Doug Aamoth, reminding you to subsequent time to…
BOTH. Stay safe!
