    Legacy hardware and operating systems are battle tested, having been extensively probed and patched during their heyday. The same can be said for software written for these platforms – they have been refined to the point that they can execute their intended tasks without incident. If it is ain’t broke, don’t fix it. One could also argue that dated platforms are less likely to be targeted by modern cybercriminals. Learning the ins and outs of a legacy system does not make sense when there are so few targets still using them. A hacker would be far better off to master something newer that millions of systems still use.

    Tell me you know nothing about cybersecurity without telling me you know nothing about cybersecurity. Wtf is this drivel?

          You really think that infrastructure IT is dumb unless it can brush off a Stuxnet-like attack by the CIA and Mosad? Most RR traffic signals in the US are run with mechanical logic, physical switches connected to circuits closed by steel wheels on steel tracks. Do you really want a “move fast and break things” tech bro to update all this stuff for us?

          All kinds of infrastructure uses ancient software because it’s reliable. Updating it just to protect from hackers causing damage is likely to cause that damage unintentionally while doing little to protect from hackers anyhow.

            It must be updated sometime or risk being archaic and unmanageable. Chances are high they are paying insane amounts for those legacy mechanical switches you mention.

            The actual logic is usually very well portable to a more modern ecosystem.

              Or these companies could pay to train (no pun intended) technicians to learn the systems they’d like to maintain. No matter how old they are.

              Until entropy comes for the actual hardware (assuming they won’t invest in remanufacture or production of replacements). Re-engineering a successfully working system is more costly and might result in worse outcomes, especially in the near term.

                Often these system rely on old components which are just not made anymore.

                People don’t design every switch, computer and chip themselves. They buy whatever mainstream stuff is available at the time and combine it into a system

                If you want to resupply those old parts you literally need to search Ebay to buy some weird outdated 2nd hand MSDOS PC to put in your “awesome reliable railway system”.

                Upgrading at every new whim is of course bad, but once your system reaches legacy age it’s often necessary to fully overhaul and modernize it for the next ~15-20 years.

            Even if it’s archaic, a lot of these systems aren’t secure which can be done relatively easily and cheaply with things like basic firewalls and stunnel.

            uses ancient software because it’s reliable

            HAHAHA!

            I just have to laugh at that idea, since I’ve been using computers since the days that those OSes were in common use. Reliable is not what I would call a lot of that old stuff for sure.

            The bottom line is that ancient software will likely have ancient security vulnerabilities that would be trivial to exploit and take over or destroy those systems. It’s not good.

          They could socially engineer their way in regardless of some machine being MSDOS or not. Basically if they can gain physical access to the device, or convince somebody to do something with the device it hardly matters what it was running since it can still be compromised.

          Sure, but how likely is this in this specific scenario. We’re talking about a system that’s not even directly controlling the train but just a display on it. The worst that can happen is that those displays won’t work until the system is reinstalled. That’s hardly a lucrative target for modern hackers. There’s way easier target which are worth something.

            I’m not talking about this specific instance, just that block of misinformation/generalisation. Saying that legacy systems are well-secured because they’re “battle tested” is sheer ignorance.

            Take side-channel attacks for example. A timing attack is something programmers from the 60’s and 70’s would not have taken into account when writing their hashing algorithms. And speaking of hashing, what hashing algorithms were available back then? CRC32 or something similar? What about salting? You get the idea.

            Not to mention that legacy operating systems don’t get security updates. Let’s assume that DOS is secure (which it definitely isn’t), but if that statement were correct, would it apply to Windows XP as well?

            All I’m saying is that the article is dead wrong. As software developers in this century, we’ve come a long way. We’ve developed security best practices, written libraries and frameworks, and come up with mitigations for a lot of these security vulnerabilities. These solutions are something that closed-source legacy systems (and anything without active maintenance) would never benefit from.

      It really depends if these systems (that appear to control arrival boards) are on a network or not. If they’re not, then there is minimal risk to leave them the way they are. Somebody would need physical access to the devices to do harm. If they are on a network then that’s a pretty big deal, but some attacks could be mitigated against by tunnelling and/or additional packet filtering to ensure the integrity of messages.

      Continuing on a railway theme you should be FAR more worried all the devices that run up and down the side of railway lines - PLCs that talk with each other and operations centres to control things like lights, junctions, crossings etc. If they’re more than 5 years old then chances are then all that traffic is in the clear, and because these things live in boxes by the railway line, it wouldn’t take much to break into a network and potentially kill people by running two trains into each other.

          The job might be remote, doesn’t mean the system is remote. For all you or I know they want somebody to reverse engineer the protocol of this thing, which could be some weird board & driver that hooks into an old PC so they can switch it out for something else.

          Well yes. You can code software remotely. That doesn’t mean the end system is reachable through the network. Given it’s DB, I bet these systems are still patched by floppy. Until very recently they’ve used floppy’s to distribute train schedules to be displayed in the train.

          Doesn’t sound like this system is safety critical. You should be more worried if some hacker can change train signs from stop to go. If you ever ride on a train and see steel boxes by the side of the track, those are control systems and they run up and down the line. They might be locked, or possibly alarmed but that’s about the extent of their protection. A simple attack would be to just take an axe to one, or set fire to it. A more sophisticated attack could snoop on the profinet traffic and do something evil.

        I work primarily in a Long Tail language (languages don’t die, but they have a long tail where usage slowly creeps away). I tell the business that we could ultimately solve all the problems with the platform except for one: finding new programmers to hire for it. That’s what will ultimately force us to migrate. Doesn’t have anything to do with cost or ability to take on new features or handle new ways of doing things.

          I’ve worked in that area. It was broken back in the 90s and I doubt the crusty old parts of the system have gotten any better. I was tasked with writing a more modern wrapper for part of the legacy system, and when I asked for documentation I was told they had literally nothing to give me.

          I was just an intern at the time so maybe someone with more clout could have gotten sometime to dig in a forgotten closet for old technical docs, but it still strikes me as a very bad sign when technical docs for a system every agent uses all day every day aren’t immediately available on the company’s intranet.

        I know for sure several airports are using OpenVMS, and there are more we don’t know about, as some companies keep running yheir stuff for decades not asking anyone for support.
        And I’m sure There are multiple other old systems out there, it’s too hard to replace them.
        And they work! Our VMS stuff runs great, it’s fast, and the uptime is measured in decades sometimes. So the problem is hardware: we rolled out the first production x86 version this year, so our users are fine (it’s still an issue of porting your software, but it’s not as terrible as building everything from scratch), but before that OpenVMS could run on Itanium servers at latest, and the platform was dying off since the beginning of 2000s, so it is a problem to find a normal replacement machine now.

    Not gonna lie, part of me wants to relive the SoundBlaster and DOS extenders era and watch stuff with QuickTime. Tinkering with config.sys and autoexec.bat was quite fun back then.

      Was it really FUN or is it not just nostalgia? I would not reaaaally want to fiddle with the autostart-crap again. It often took soooo long. Even with those auto-optimizers…

        With dos 5.x I started creating some fancy auroexec menu at boot that switches between several configurations depending if I wanted to run windows, need a lot of xms or a big chunk of Ems (640k was NOT enough for everything).

        It was somehow fun.

        But at least, if something is not working, it was entirely your fault. Now? It’s probably windows update who fucked up something you desperately need right now.

          That’s a good point, yes. At least we knew what fucked up. Today you can’t. It’s too much and too complex. And nearly nothing is under your direct control anymore. Only android or ios are doing it worse and take all of your controls away.

        BMC is doubtful, other sources indicate that the hardware is from 1996, so it’s not just old software. So I’ll guess a KVMoIP device is bolted on (probably a relay on the power input, VGA, USB for keyboard and ‘floppy’ (Win3.11 was well before USB, but the hardware from 96 may have USB and the BIOS would likely make it viable for a DOS to use it).

        COBOL has entered the chat

        e: good for legacy employment though. A relative of mine is a Z80 programmer by trade, and he can effectively walk into a job because the talent pool is so small now. Granted - the wages are never great but never poor, and the role is maintenance and troubleshooting rather than being on the leading edge of development - but it’s a job for life.

            I’m in two minds about that. One the one hand, yes, of course - as all the original COBOL folks die off, the skills will be even rarer and thus worth more.

            On the other hand, if we keep propping up old shit, the businesses will keep relying on it and it’ll be even more painful when they do eventually get forced to migrate off it.

            On the other other hand, we know it works, and we don’t want to migrate everything into a series of Electron apps just because that’s popular at the moment.

              Part of the problem is the cost of moving off it. Some companies simply can’t pay what that would cost, and that’s before you consider the risk.

              Tough spot to be in.

          Massive risk to that change too.

          So many people don’t understand how risk informs everything a business does.

          What cost is there to a given system being down for one hour? A day? Any regulations around it?

          Often it’s better to pay a known quantity up front than risk potential outages where you can’t predict all the downstream affects.

      Oh, everyone who ever travels by train in Europe will tell you that the German infrastructure is very much broken. You’re lucky if your delay is less than a day travelling through Germany.

        Well I live in germany and therefore use the train network on short and long distance frequently and while it is unreliable, “a day” of delay is something I have never experienced.
        Most of the delayed trains are late by less than one hour (still atrocious, but not a day’s worth by any means).
        I actually experienced only once a situation where we were given the choice of a hotel or a continuation of our travels by taxi (which we chose) because the train we were in was late one hour or something and the other (last for the day) train could not wait.

          Well, it’s based on experiences travelling through Germany proper - for example Denmark to France or Italy, including transfers. Often the delay will just be a couple of hours, but then you miss your transfer and you’re screwed.

          Also if you’re on your way to Switzerland the Swiss have no patience for disruptions in their services, so if a train is delayed coming from Germany they’re likely to just not accept it into the country at all.

          I have also heard from people who were told to spend the night in the train, which DB just parked in the outskirts of the city for the night. That way they could offer passengers a place to sleep in the cheapest possible ways. Pregnant women or families with young children were asked to check in to hotels.

        That’s another part of the infrastructure, though: We just don’t have enough rail as well as backup rolling stock.

        And as the federation finally decided to spend some money it’s going to get worse in the next decade or so due to outages due to new constructions being linked up to the old stuff.

        As to the age of the infrastructure – I mean it’s the railway. If a rarely-used branch line still uses mechanical interlocks and there’s no need to upgrade the capacity then the line is going to continue using infrastructure build in the times of the Kaiser. It’s not like those systems are unsafe, it just might be the case that unlike in the days of ole those posts with a gazillion levers aren’t manned all the time so you’ll see an operator drive to it with a car while the train is on its way. Which really isn’t that much of a deal when the branch line goes to a, what, quarry maybe sending out a train every two months or so. Certainly better than to demolish the line and use trucks instead.

      Is it broke if no one is able to fix it?

      The reason for it to run on such an ancient device is because nobody wants to touch the scripts running on these devices.

        A lot of these systems are also always on.

        Used to work at an airport that had a similar issue, turning some of these systems off simply isn’t possible. So you end up having to run the replacement system simultaneously with the old system for a few days. Can’t simply take it off line for a day.

            It’s an expensive problem, especially if it’s a system that’s being used all across the airport by regular staff.

            You need to train thousands of employees to use the new software, you need to have one person using the old software as a backup, while the other uses the new software, often while surrounded by hundreds of often angry customers.

            And if something goes wrong, which it invaribly does (even if it’s user error or someone snagging a cable), shit can get very expensive. Small delays, add up to larger delays, and cascade through the entire system. Delayed flights, tens of thousands of euros in costs, hotels for thousands of passengers, missed flights, missed meetings, damages, lawsuits, penalties for missed landing/take-off slots, missed time windows for certain cities which don’t allow flights after a certain time, etc. And often you discover legacy stuff while you’re upgrading that needs fixing, stuff that no one knows how to replace anymore or is physically hard to access.

            Sometimes it is genuinely better to leave it. COBOL is 60 years old. There’s still plenty of stuff running on it, exactly because it’s often too expensive and too risky to replace.

      These probably operate completely shut from other networks/internet, so I definitely agree. But I guess a lot of folks here are Linux maniacs and can’t stand something running ancient and obsolete OS while the all-mighty Unix-based operating system could solve all of the problems, not mentioning that it would create more in the process.

      The fact they’re still running on dos is a clue that either they can’t figure out how to upgrade or they don’t want to upgrade or they simply won’t allocate the budget to upgrade.

      It generally boils down to money. Shops like that are toxic. They somehow don’t have the budget to keep their business afloat, means you’re not getting a raise.

      If you take this job, you’re obsolete. Getting the next job will be tough. You’re interview at the next potential role what did you do at your current role? I ran dos on 30 year old machines. Interviewer: I’m sorry, but we need someone with experience in Windows ME.

      You think the existing system is documented?

      It’s going to be a mess of things written in 6 different languages, magic numbers all over the place. Unit tests? Predates all that. Even if you tried, the first you’ll know about an error is when you turn the news on and there’s two trains upside down and on fire.

        It is definitely the exact opposite of this. Even though I understand why you would think this.

        The thing with systems like these is they are mission critical, which is usually defined as failure = loss of life or significant monetary loss (like, tens of millions of dollars).

        Mission critical software is not unit tested at all. It is proven. What you do is you take the code line by line, and you prove what each line does, how it does it, and you document each possible outcome.

        Mission critical software is ridiculously expensive to develop for this exact reason. And upgrading to deploy on different systems means you’ll be running things in a new environment, which introduces a ton of unknown factors. What happens, on a line by line basis, when you run this code on a faster processor? Does this chip process the commands in a slightly different order because they use a slightly different algorithm? You don’t know until you take the new hardware, the new software, and the code, then go through the lengthy process of proving it again, until you can document that you’ve proven that this will not result in any unusual train behavior.
