Do Old Viruses Work on Modern PCs? | Nostalgia Nerd

Big thanks to TotalAV: Visit www.totalav.com/nerd70 to get 70% off TotalAV complete protection... I don't know why I get curious about these questions. But here I am, trying to run old computer viruses, DOS Malware and other such malicious code on Windows 10. I thought we could first take a look at some malware from the 80s and 90s, before trying to get it to run on a modern PC. Then it seems a natural progression to run as many of these malicious files as possible and see if it is indeed possible to take down a Windows 10 PC using just DOS Malware.

  • Even with a dedicated computer, why not run a virtual machine so you can restore in a matter of seconds after a virus activation? If you don't run a VM, don't you have to reinstall all of Windows from the recovery paritition? Just curious.

  • I remember after spending the 90s going bareback on dialup BBSes circa 93-95 and then the internet proper circa 95-00 i only got one virus: the tai pei virus. It inserted ~400 bytes of code to DOS .exe files in order to spread itself but otherwise it did nothing beyond spreading itself. I noticed it when a dos game (like descent or something) ran a CRC (.exe file size) check at launch and it detected it was ~463 bytes larger than it was supposed to be and then a proper virus check and a-ha its the tai pei virus. Later dealing with work machines and other people's computers I came across one of those first gen fake virus/malware scanners (the one that would try pretending its windows defender and pop up the YOU HAVE BEEN INFECTED / BUY THIS ad/window) and that one was a tricky MFer. One variation would send three small .exe files in 3 different system folders then go into the windows registry and insert commands to run these .exes on startup. If you caught 1 or 2 of them all 3 of the .exes were able to recreate the other .exe files if deleted, so it would do that and move the .exes to a different folder + different part of the registry until you were able to catch all 3 at once (as virus scanners at the time didn't catch them) Then later once virus scanners started catching them they got more malignant, originally trying to block your computer from running .exe files that had the same filename.exe as all of the virus scanners at the time (requiring you to, example, rename malwarebytes.exe to iexplore.exe or notepad.exe or something else "benign" to the virus creators) then once ppl figured out it was blocking the virus apps' .exe files it went to its nuclear option and changed your windows around to where all .exe files would be opened by your web browser instead of loading up as an .exe and this was tricky because after a proper boot up you couldn't run ANY exe files unless you got really clever (as the virus by this point was a TSR that would hang around trying to block .exe launches and changes to the registry, that is if you could even get regedit to run) so I remember ultimately defeating it by finding some little backdoor to launch the malwarebytes exe and fix it, but it was a pretty good fight for a good 20-30mins IIRC. Otherwise, I've been fortunate enough to have enough common sense to only click on the RIGHT shady .exe files to avoid further viruses (honor amongst thieves in the Warez scene, eh?) and thank god those fake virus scanner scams died out by the mid-late 00s

  • Back in the 90s the Form virus was going around college. I grabbed a copy onto floppy to take it home to mess with. It ended up infecting the boot sector of the HDD :) but as it wasn't destructive it was fine. I'd just boot from a floppy instead, which needed to do anyway to run Elite on our 386sx. Anyway. Used a hex editor to see the message it was supposed to display but I never saw it "The FORM-Virus sends greetings to everyone who's reading this text. FORM doesn't destroy data! Don't panic! Fuckings go to Corinne." I may of edited the txt then took it back to college. Can't remember what I wrote though.

  • If you really really want them to and go to pains to make it happen then yes. Otherwise you can be safe in the knowledge that DOS era viruses/malware are a thing of the past - current viruses and malware not even Apple is safe from despite the marketing telling you otherwise. But you can be safe in the knowledge it will just cost you money because today it is mafia level, not some random shit delighting in deleting files because they can for no personal gain.

    Crow MigrationCrow MigrationMaand geleden
  • Back in the day when I was a bonafide AV researcher we would have considered ANY change to virus source code to be equivalent to creating a new variant of the virus. Even changing it to remove a nasty payload was looked down upon. If you were to do this you would have gotten fired from most AV software companies. Some people would even consider changing an infect host so that the virus code never got called (essentially neutering the virus while leaving it’s code attached at the end) to be making a new variant even though that virus code could never get called. It was kind of annoying when some testers would have these neutered viruses in their collections instead of unmodified viral hosts. Depending on how the AV definition was written it might not consider a file like this infected and then we would get dinged for not detecting their virus sample. Also, your comment that most of these old DOS viruses need to wait for a “period of calm” until it can spread itself to other files is incorrect. The vast majority of DOS viruses (especially the direct action type) will immediately search for files to infect (usually in the current directory and sometime standard dos folders that usually exist on all drives, or it might search in your $PATH) and infect them straight away before relinquishing control to the host program code. Direct action viruses do this because, like all “good” viruses, they don’t want to give away their existence on your system. So a direct action type virus will want to quickly infect as many files as it can and then get back to running the host code in as short of a time as possible so that you don’t notice a difference when running an infect program versus a non-infected. If it sat around waiting for calm before infecting then you would notice when your text editor takes a lot longer to load. Then there are resident type viruses that attempt to get around this and infect more files over time by using a different method compared to the direct action infectors. The resident infectors will not immediately look for files to infect (with some exceptions, like a hybrid type infector) but instead it will reserve some upper memory and then load itself into that memory. Finally, before returning control back to the host code, it will edit the interrupt vector table (IVT) so that certain interrupts (basically the DOS API functions) will point to the virus code we just copied into upper memory. That way when that interrupt is called (like int 21 Ah=3Dh Open File system call, for example) its code gets called and it will infect the file that is about to be opened. Once that’s done it relinquishes control to the original interrupt vector that it saved when it changed the entry in the IVT. Pretty neat how they all worked. And this is just he basics. One final note, the vast majority of old DOS viruses never had any payload, or if they did it was completely harmless. Most people think that a virus is destructive by nature, but that’s not true. Oh, and I liked that you showed the Elvira virus. At our lab in the 90s whenever a big new virus got into the news we would have tv reporters come in to shoot video for their reports about them. We did a lot of PR stuff like that including once we had the actual Elvira, Mistress of the Dark, come into the office and into the virus lab to shoot some video. We showed her the virus named after her and she got a kick out of it. She was just like her TV persona. I would have been seen in the background in some of those PR events, but I can’t recall if I was in the Elvira one. In fact I think that was one I wasn’t in and I was upset about that. If you want to know more about the AV scene in the 1990s I got tons of stories.

  • I assume the reason that modern anti-viruses recognize these old viruses is precisely because these are well preserved. I would assume some of the more obscure ones are not as well recognized. Also, I imagine a lot of antivirus development teams are pretty close to hobby virus writers who don't have real malicious intent. Or at least vice versa. I don't think many hobbyists would want the programs they're building for fun to actually be used to hurt people.

It was more of an annoying program that hid in your system but it would change all of the colors of your system to some seriously *eye searing* colors. After you spent time putting all of your colors back to what they were it would do the same thing again when your system rebooted.
