    Correction: zero day is a case when discovered vulnerability haven't been fixed yet. Not all software bugs are zero day. Only the ones that's discovered and used before software manufacturer produced a patch to fix it.

      No its called zero day exploit because its found and than the clock starts ticking for antovirus providers and manufactures. Its not zero day anymore when the is a path its not zero day anymore when...well actually as soon as the new spreads even to a small circle of insiders, its not 0 day anymore.

    3:29 For anyone interested: this is only partially true. A zero day IS a bug, but not every bug is a 0-day. A 0-day is a bug that the vendor of the product in question has known about since 0 days (so: they don’t know about it while it is already being exploited/found by someone else)

      Thank you. The most common exploits stem from companies not updating known security vulnerabilities. Probably because hackers also know about them and can look for companies that havent fixed them. But that's what is scary about zero day. They are unknown and can thus possibly be exploited while the hackers remain undetected till the vulnerability is discovered, and even then who knows what they could have done. Become an ethical hacker and make some stacks for real

    • Lyks Zyxer

      Honestly that whole segment of the video is ridiculous and totally missing the point from a technical point of view. The next thing that's mentioned is encryption which serves a totally unrelated security goal. Of course both can lead to data being stolen but that just comes with a compromised system. Encryption doesn't really make a difference when someone has physical access to a system that's powered on. And it doesn't really make a difference for sabotage.

    • dzerkle
      dzerkle 4 months ago +1

      Ok, I shall give you all an actual precise, accurate definition: A zero-day is an exploitable vulnerability in software for which there is no current patch (update with a fix) at the current time. That’s it.
      The origin of the terminology is a bit fuzzy, but it refers to time in relation to when the patch came out. A common interpretation is that IT departments would get a vulnerability patch announcement and give themselves a certain number of days to apply it everywhere. It can also refer to the number of days since the patch was released. This is tracked because having old, unfixed vulnerabilities on your systems is terrible; the hackers have had a long time to weaponize the vulnerability.
      So, a zero-day vulnerability is one where the number of days doesn’t exist, because there is no patch yet.
      It is not always due to a bug. In fact, it usually is not.
      It is not always secret. If a vulnerability is announced but not fixed yet, it is still a zero-day. This always sets off a race amongst the software vendor and the hackers.
      It is not always exploited. Sometimes, a zero-day will be announced without a patch, but the hackers aren’t able to use it before it is fixed.
      It does not always allow code execution, although those are usually the worst.
      Even if it does allow code execution, it is not always remote code execution.
      It sometimes but does not always require (victim) user interaction. The ones that do not are called zero-click. Zero-click remote code execution vulnerabilities are called “wormable”.
      So, the very worst vulnerabilities are zero-day zero-click remote code execution. Governments use these to plant spyware on your phone. Stuxnet used these. They are nightmares because there is no good way to defend against them. They’re also worth around a million dollars each to the right buyers.

      @Simon Burgess ac id say to have 1 version down of the most recent software unless specifically told not to do so. This is because a developer might of missed a bug that hasn't been accounted for in the newer version of software which may not reveal itself until clients begin using it.

    FYI, the reason those centrifuges are so fickle ( said around 9:47) is because of the precise balancing and precision you need on the bearings to separate Uranium 235 from 238. They need an air layer in the bearings (because mechanical bearings with an oil layer can't go to high enough RPM and aren't precise enough) I.E. gas or magnetic bearings to work correctly which need final tuning to make the system run correctly. It would be incredibly easy to just change 1 or 2 parameters that would make a mag bearing system rotate out of orbit and they can literally tear themselves apart if you wanted it to. Stuxnet running at bad RPM ranges likely caused the motors and bearing stators to run at bad efficiency (creating a lot more heat) which can "cook" your mag bearings, motor, and stator by basically annealing the laminar sheets of steel and changes their characteristics (which also removes their magnetism and makes them run horribly). This would likely do this to the motor stator and rotors as well.

      in the short term yea sure, some home appliances doing some minor extra things for u arent worth much. It may seem just like a bit of luxury for the cost of exposing urself to security risks, but in the long term maybe not. a bunch of minor things saving you a tiny bit of time all added up in ur lifetime x the population of a country can amount to a lot of time that could be used for competitive edge. a major reason why certain civilizations evolved to be more advanced (for example, european ones vs native americans) can be attributed to the extra time people had after taking care of their necessities such as food. there are a lot of advanced civilizations that arose from parts of the world where farming is efficient vs not so much in jungles or deserts.

    When it comes to cyberwarfare, every nation with sense operates on a policy of 'Those in the know aren't talking, and only those who are not in the know are talking.' I once chatted with one of their ex-security guys and apparently Fort Meade is so insanely paranoid when it comes to security, they immediately began renovations on their headquarters when some college discovered a way to get wireless data through the massive Faraday cage already cladding those buildings. These are the same guys that encase every wire coming into Fort Meade inside sensor-lined concrete.

      What nobody talks about is how, probably Israel, killed some of the engineers from the nuclear plant who were trying to clean it up where killed on the streets in the city.
      And how the security expert from Microsoft had an unfortunate accident before his big talk about Stuxnet at a security conference. Probably that last one was purely an accident and coincidence. But the dead Iranians clearly aren't. It does indicate that working in IT Operations and Security has become a more dangerous job than it used to be. And as XKCD 538 indicates the weakest link at some point might end up being us.

      What surprises me at times is how long it really took for those things to happen. I agree that something like stuxnet happening was huge, but first of all because it became public, and people started to think about it, and take some things people in the security industry have been saying for a long time now, a lot more serious.
      But.. imo, this being possible wasn't news, and shouldn't have been news for decades now.

      I really like the analysis of Stuxnet called "To kill a centrifuge" by Ralph Langner as it explains lots of technical details about Stuxnet and centrifuges in question. Also the virus portrayed in this video is actually a second less sneaky version of Stuxnet, the first one was much more sneaky and destructive, but much less exciting as it had no 0-days nor any way to spread via local network.

    As someone who works with PLCs its nice to see them actually mentioned. I wasn't aware that Stuxnet hit the PLC's themselves I thought it crippled the SCADA system. I guess that shows how PLC's tend slide into the background in the media. The only comment is you used a modern Logo PLC (more akin to home automation or tiny single function machine) instead of the S7-300 more akin to massive machines and entire factories.

    This representation is somewhat inaccurate: Exploits, big and small are found all the time and are patched all the time. They're not nukes, you can't just sit on one for years because it may either get discovered and patched or rendered pointless by some other update or just a new software/OS/etc. They're also typically already out and about (ex: Meltdown) and, if big enough, get a ton of attention and very fast reaction to it. The log4j fix is an example of this. That doesn't mean they can't do a ton of damage, it's just that more often they're just happening all the time, and the vulnerabilities are just getting patched all the time. Organizations that are bad at security and keeping up with this, government or otherwise, are obviously the easiest targets.

    • konstagold
      konstagold 7 months ago +7

      @Sovrim Terraquian true, though that bug was exploited primarily cause the patch sucked and people weren't updating their unix servers. I guess the point I'm making is banking for a long time on no one discovering the discovery that you bought and hired a team of people to implement maliciously sounds like a stupid idea. It's like finding a $100 bill on a crowded street. You better hope no one else saw it. But as I said, I concede that sometimes exploits exist for literal decades, so a fair example for sure.

      As a counterexample, the Shellshock bug had existed since 1989 and wasn't identified until 2014. It is certainly conceivable that, even in the absence of conspiracy theories about government/corporate partnerships, a devastating bug could go unnoticed for decades.

  • ゴゴゴFeelsHowdyゴゴゴ

    For anyone wondering: the reason for the name "zero day" is that before you release your software, you're supposed to debug it, and for every bug you find, you have X days until the release date to fix it. But if you discover a previously unknown bug in an already-released software, the devs have "zero days" to fix it because it should have been fixed before the software released.

    • paenutz

    As a Senior Information Security Engineer, I was very intrigued to see what would be covered in this video.
    I'm pleased to report that it's largely very accurate, and I look forward to seeing more!
    If you want to know more about this topic / Stuxnet (and I mean almost mind-numbing levels of details), read or listen to Countdown to Zero Day. Other great cybersecurity books I've recently listened to are (1) Sandworm which is about Russia's terrifying cyberwarfare capabilities and attacks and (2) The Cuckoo's Egg which is the story of the first proper Incident Response and the methodology borne out of that.
    Practically the entire industry thought that the next major war would have a HEAVY cybersecurity element, but it's been (morbidly) interesting to see that seemingly no such thing has come of the Ukraine war yet. It seems that, in most cases, "cyberweapons" will be relegated to intelligence gathering and "under the radar" attacks.

      From my (admittedly incredibly distant) perspective it looks like disinformation is the most visible weapon currently in use lately.
      On one hand that's a minor relief on the network side, but on the other it's really annoying seeing less discriminating contacts willfully spread easily-disproven nonsense. That's a whole can other can of worms though, and neither this video nor this comment are part of that problem.

      Merennulli 4 months ago

      @ShihammeDarc I know you're trolling because this is an absolute horseshit reply and too obvious for you to not have realized it when you posted, but I'll bite:
      - Greenhouse emissions ENORMOUSLY spike when militaries actually go to war. Production increases to replace things destroyed, vehicles burn fuel FAR faster because they're being actually used rather than just periodic drills, equipment is transported all over the planet to deploy, oh and THEY ARE LITERALLY BURNING CITIES AND FIELDS. A few people skipping vacation this summer isn't going to offset a fraction of that. Even with the 2020 lockdowns worldwide and nearly all of us not traveling, CO2 emissions only dropped 5.4%. With everything going on right now, CO2 emissions from gas powered vehicles have dropped by only 1%. So 0.21% of total CO2 emissions.
      - If you actually thought your taxes don't benefit you, you would have to have no concept of how your society works. And I already mentioned the case for if your country isn't one that participates in other people's wars.
      - The impact of Ukrainian exports being stopped hasn't been felt yet. Their harvest season is coming soon. If the current negotiations don't pan out, you WILL be affected wherever you are because your food supply will be competed for by countries like Egypt who just lost theirs. Even if the negotiations are successful, a lot of fields were burned so you will still see an impact.
      - We have had fewer and more constrained wars since adopting this gamesmanship of sanctioning each other and supplying smaller countries rather than going to war directly. And even those proxy wars have fallen out of vogue in recent decades. Your argument is the geopolitical equivalent of claiming "We've always used bloodletting without antiseptic, so it'll never change."
      Saying you don't care after saying you give condolences to them is directly self-contradicting.
      1. It is. See above.
      2. You can. See above.
      3. That's called sociopathy.
      This is all the troll feeding you get. I'm not going to reply to you further since you made it so obvious you were just trolling.

    • ShihammeDarc
      ShihammeDarc 4 months ago

      @Merennulli
      - The 6% of greenhouse emissions as you said are a general by-product of military activities, a war didn't increase it significantly. (I have no sources to back this up, but the economic depression caused due to the war might even reduce emissions due to rising gas prices in some countries and less trade overall)
      - My nation in specific doesn't get involved in wars, but even if it did and my taxes went to fund fighting there, it's not like my taxes benefit me individually in any significant way.
      - Ukranian exports don't affect my country in general, but the prices of a few goods did increase slightly although it's not like it's unaffordable for me
      - That literally ignores the fundamentals of human nature. As if humans haven't been senselessly killing each other for our entire history.
      My condolences to people affected but I can't personally be bothered to care about them when
      1. It isn't affecting me.
      2. I can't do anything about it.
      3. I care about my personal problems way more than problems of others.

    • Merennulli
      Merennulli 4 months ago +3

      @ShihammeDarc Normally people aren't cool with other people dying needlessly.
      But if you need other reasons:
      - 6% of greenhouse gasses are from military, so wars are affecting you even if you're nowhere near them.
      - If your nation is one of the ones that gets involved in other people's wars, your taxes are going towards them. If not, money your nation would otherwise have obtained from the nations that do is lessened.
      - These wars usually involve sanctions which further worsen your economy. The 2022 Russian invasion of Ukraine is an extreme case since a nuclear superpower with a penchant for genocide picked on a friend of NATO which Russia had committed a genocide against once already, and that also happened to be the #5 exporter of wheat in the world. But even with smaller wars with smaller sanctions, there is an effect on the global market.
      - Everyone else in the world being outraged about senseless killing enough to take actions like sanctions or military aid makes it a little harder for others to commit acts of senseless killing which could include your nation's leaders or neighbors.

    Very well presented. I think you should have made more clear how enormous 1MB is in this scenario. People take pictures or videos of hundreds of MBs or even GBs all the time.
    But this is just code and 1MB of just code for one single purpose is crazy.

    • Eyal Kalderon
      Eyal Kalderon Month ago

      @HH A few things to note here: it really depends on whether we are talking about the average size of graphical (point-and-click) programs versus the size of console programs, like Stuxnet. Graphical programs tend to be much larger than console programs, often several megabytes in size versus several (kilo)bytes for most console programs. For example, *bf1.exe* (the Battlefield 1 game executable) sits at about 13MB in size, depending on the specific version you have installed. This is all just code, so you can imagine how densely packed the information is inside a compiled binary such as this.
      To give you a similar perspective on the console program side of things, *cl.exe* (the Microsoft Visual C++ compiler executable) is a few hundred _kilobytes_ in size. This is an incredibly complex program designed to perform a very complex and open-ended task, but it's much smaller than *bf1.exe* because its scope is much narrower and it doesn't have to display anything graphical.
      So to have a virus (usually a single-purpose console program designed to do little more than spread and replicate itself, often kilobytes or even mere _bytes_ in size) take up >1MB of space with just code is very unusual and unprecedented. Stuxnet, as a non-graphical program meant to run in the background, had to have been _enormously_ complex to be that heavy.

    With proper security monitoring zero days are not that scary. RCE would be detected and countered as it happened and the spread would be minimized.
    The problem is many corporations spend money on cyber security insurance because it's cheaper than proper security.
    Just like having the CEO pop their golden parachute and take the blame for something bad the company did cyber insurance lets the corporation save money until things go bad and then they get a big payout. The only ones harmed are the customers.
    Yet another instance where putting profit over everything is costing average people.

    It used to be that zero-day vulnerabilites were immediately disclosed as the bad guys had them, and the more people who knew about them, the better they could change the security posture. However, the banks and Apple didn't like not having "advanced notice", so they changed to the current model, where severe bug may be unpublished for a period of time while the vendor makes corrections, rather than launching into a 90-day sprint to solve a Heartbleed bug.

    One interesting bit that wasn't covered: it's mentioned in the video that stuxnet got onto the research facility's hardware due to a spy or mole. That may not even have been the case: it's theorized that instead, whoever was trying to deploy the virus did so to either the Siemens controllers or something that would be connected to them, at the source. That is, these machines were infected with stuxnet en masse in their countries of manufacture in the hope that at least some of them would make their way to Iran. And it worked. It's possible that this is also what led to its discovery by the western public: enough of the infected machines made it to western countries that a user who happened to be operating one such machine stumbled on it.

      @Nathan Keel the outside propagation theory I laid out was what I read several years ago: there's new evidence that is really was an inside job?

    • Nathan Keel
      Nathan Keel 7 months ago

      It's proven that it originated and propagated from Iran. It was also identified by a Belarusan cyber security firm. Which is closely aligned with Russia and far from the west. The only 3 ways it got in was from someone sneaking it into a Natanz employees labtop, then they brought it to their job where it propagated. Or they had an inside man. Or last they snuck inside the facility and planted it, which is highly unlikely. I also believe it is a highly unlikely chance that the PLCs were infected before or during transit to the facility. Last thing is that Stuxnet was a worm, not a virus. All worms, viruses, trojans, etc are malware(malicious software). This is my opinion from the known facts. I'm not saying the theory you laid out is wrong, but personally i do not believe there is any evidence of a bunch of random PLC's being infected and hoping one ends up inside Natanz's air gapped facility before all the rest of the world.

    It kinda terrifies me that my university labs have PC's still running windows XP. They're obviously not connected to the network at all, but imagine what one guy with a long cat5 cable and a few minutes could do to the whole university network.

      The problem is not that they are not willing to upgrade but rather that Software Companies are either to lazy or that the Software that they build are from the 80is or 90is. Everyone who has a little unterstanding how OS works knows what works on a Win10 does not mean it is going to work on older Versions. A good solution would be to switch those Softwares on Linux but I guess the American Lobby would have a small problem with that and on the other hand to convert the whole Software on a different Kernel and Operation System would take ages.

    The amazing part was not so much about the worm spreading over a usb stick. That kind of stuff was done in the 80s with floppies. And its ability to use zero days was also not too special as all exploits found in the wiled are zero days. It was its stealth and really specific targeting to attacked a complicated air gaped machine was what got everyone's attention.

    It's amazing how far technology has come. As with many things, if you don't keep up with it you get left behind.
    I remember thinking awhile ago how much I knew. But in the blink of an eye I'm old news and outdated.
    Trust the fact that the alphabet boys are keeping up with this advancement. I'm always curious how much thought goes into these trends. Such sophistication and plotting goes into these attacks. Specifically to lay in wait.
    The newest version I saw was talking about storing itself in the bios of a machine. That gives me worries at night for sure if I was a network manager.

    Zero Day doesn’t refer to the software flaw itself, it refers to the small window of time between when it is discovered and when it it publicly announced. This is when it’s most valuable, because it can basically be exploited at will, because no one even know s to look out for it yet. So any flaw, no matter how major or minor, can be called a Zero Day during this limited timeframe. It doesn’t depend on complexity, just how widely known is it.

  • D. Lawrence Miller

    3:30 maybe this is a bit philosophical and pedantic (a la "a tree falls down in the woods"), but I think your definition of zero day is a bit unusual. I don't think zero day means "all vulnerabilities that exist in a technology" it means "any vulnerability *which has been discovered* by a researcher." Since most people only learn of a zero day exploit once it has been used in an attack and researchers have noticed and named it, "zero day" has come to mean "new attack pattern that just made its debut." This better suits the etymological origin anyway. "It has been 0 days since [disastrous thing happened]."

    • GoldenPantaloons

      More accurately it's "any vulnerability which is unknown to the developers" - the idea being that once the vulnerability is known, its value starts to diminish over time ('n'-day vulnerabilities).
      A 1-day vulnerability might still be missing an official patch, widely unknown, and as such invaluable in the right hands.
      A 7-day vulnerability's probably patched, worthless vs. security-conscious targets, but valuable for other uses. Depending on the software in question there could be a vast quantity of old installations runninng.
      A 500-day vulnerability is pretty much worthless. (Well... I say that, but if I recall correctly the ransomware attacks that devastated some public health systems a few years back were using ancient exploits... the hackers had made it on the cheap, and were just kinda shotgunning it around hoping to hit something. Turned out a bunch of hospitals still had their entire networks running Windows XP hahaha)

    A zero-day isn’t just a bug, it’s specifically an exploit that has yet been undiscovered (eg “it’s been zero days since our staff was made aware of etc”). This is usually a monumental discovery, because it means this exploit may have been around for a long time undetected, and none of the programmers have any idea how much damage has been done in that time. Not every bug is a zero day, because not every bug is an exploitable issue unknown to developers.

    Ok but like this is something I hadn't realized until Sam said it outright: a weapon that cannot be revealed before it becomes useless, is a weapon we cannot shield against. The idea, the prospect of our there being a weapon so destructive, so devastating, so catastrophically armageddon that's just laying dormant, truly is something chilling. We're exposed, there could be a sniper looking at us right now, aligning their crosshair to our frown 24/7 and we have literally, *literally* no way of knowing if that sniper even exists, let alone which is his rifle, what's their ammunition, or his position.
    This is a war of warnings, a war that will only end the very second a country calls a bluff to another country that was not bluffing.

    Why is it called zero days?
    The term "zero-day" refers to the fact that the vendor or developer has only just learned of the flaw - which means they have “zero days” to fix it. A zero-day attack takes place when hackers exploit the flaw before developers have a chance to address it. Zero-day is sometimes written as 0-day.

    I have heard all these things while I was in the middle of my college, man my field changed alot in cyber security in that time frame.
    I also have a laptop with alot of old virus codes from the centuries, including the infamous I-LOVE-YOU virus. The wifi card for that laptop is removed and Ethernet port disabled permanently hardware wise, and its running Win 10 20H1 natively, with vms for DOS.
    I usually use those codes as learning materials, and sometimes algorithms within it I use for code I make.

    I don’t think you’re giving developers enough credit. It’s not so easy to develop such widespread devastating viruses as you’re saying at the end there. Not with modern security practices. Finding 4 zero days that can work together in the modern day is basically impossible.

    What stopped white hat hackers from selling the exploit, and then immediately delivering them to the software developer to be fixed?
    Why hasn't this business model changed to some sort of subscription, where security companies would buy an exploit, and then pay some daily/weekly/monthly fee until the bug was patched by the developer (this way, encouraging the bug to be kept low profile)?

      @SaintJezebel unfortunately it makes a lot of sense. :/

    • SaintJezebel
      SaintJezebel 7 months ago +17

      White hats are not nearly as common as you might notice, because of a combination of things, but here's something pertinent:
      When a bug gets reported, it usually comes after the reporter has abused it for a while and got bored or feels bad about it. So most of the time, reporting bugs can get you extreme suspicion and or bans/punishment. This alone demotivates a majority of regular (ie. non corporate employed) white hats.
      But other than this, generally, cybersecurity firms are hired in the process of creating new infrastructure. The problem is software devs LOVE to reuse old shit, so basically unless you're making a whole new internet, bugs from a billion other places will be incorporated. The internet is a lot like building a house and your house building tech only gets better the further in you've gotten. By the time you're installing solar panels, people are starting to realize the foundation is made of packed dirt.

    Ahh PLC's.. I use to have a job making programs for automated asembly lines, like a bottle cleaning line used at coca-cola. I also built the control panels from scratch too after making the CAD Layout diagram and a CAD type wiring digram program. We would number every wire because all the wires were the same color for most things and in the same wiring routing "trays". I'd have to install everything from the circuit breakers, to the Solenoids, power wires, control wires, VFD's, Input & Output Blocks, PLC, and power supplies.. plus a bunch more cool types of sensors outside the control box and control touch panel..
    It was a fun job. The popular PLC's had a pretty nice program for making the software and building the Animation and Data Value Pages with Accurate Active diagrams for the Color Control Panels on the Outside door, was fun for me and my favorite part besides starting to build it with the crew lol...
    I also did a bunch of smaller ones by myself. We did it all i learned later as far as using different PLC's and not making the customer start over.. Rockwell, Seimens, ABB and a bunch of other brands i cant think of right now.. IF THIS, THEN THAT. OR IF THIS AND THAT THEN THIS BUT NOT THAT. So yea you would have failsafes built into the program to make certain things happen in correct order and Temps/Speeds, etc..
