  • Don't get baited into back-and-forth insults. We are not animals.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.

    The power cable would like to have a word.

    We have squid games at home.

    while this is not real, something similar in principal very much was! (but not too widespread)

    see here or look up "casino dos malware"

    uh in short it erases "the disk's" (unsure which) file allocation table (pretty much the dos/windows version of a superblock). apparently some versions did copy it to memory and give the user a chance though!

    [–] Hupf@feddit.org 1 points 1 hour ago

    There also was Fake DOS back in the day

    Reminder that binaries cannot change a shell's working directory, so the non-mines will do nothing.

    (cd is a shell builtin)

    [–] BetterDev@programming.dev 3 points 1 hour ago

    I mean, you can just write a whole custom shell for this

    [–] glibg10b@lemmy.zip 2 points 4 hours ago

    Technically they could if run as root by modifying the parent process

    [–] Sasquatch@lemmy.ml 1 points 3 hours ago

    it could just reinvoke $SHELL in the parent dir

    [–] tyler@programming.dev 2 points 5 hours ago

    Good point. Also it wouldn’t stop you from just opening another terminal window haha.

    [–] CannedYeet@lemmy.world 9 points 9 hours ago

    Reminds me of gameshell, which is a rogue-like game designed to teach you the unix shell. So instead of navigating with NESW, you cd to locations. At one point you search the "garden", which is an unmanageable tangle of directories, with find.

    Based on the responses in this thread, I feel like you could present this screenshot with a "I bet you couldn't find your way out of this!" and a zip of the directory, and a significant number of users would voluntarily download it and extract it just to "prove that they could".

    [–] tyler@programming.dev 5 points 5 hours ago (1 children)

    Well yeah? And you do it in a vm. But seems like a decently simple problem anyway. ls -al and compare the sizes.

    [–] BeatTakeshi@lemmy.world 2 points 2 hours ago

    Obvioulsy whoever set this minefield thought about this

    [–] moonshadow@slrpnk.net 28 points 14 hours ago (1 children)

    Genuinely my first response. What are VMs for?

    [–] muntedcrocodile@hilariouschaos.com 3 points 6 hours ago (1 children)

    I run QubesOS BTW. My entire computer is just a bunch of VMs in a trench coat.

    [–] Allero@lemmy.today 2 points 2 hours ago

    Running Qubes as a daily driver is some serious level of privacy enthusiasm

    [–] Ghostie@lemmy.zip 21 points 13 hours ago

    I’ll hit them with an rm /etc. We got out, we go out on together and on my terms.

    They never guess the next move: Unplugs pc

    Either that or the PC keeps running anyway.

    How can you prevent users from leaving a directory?

    [–] grue@lemmy.world 7 points 12 hours ago

    Magic, I guess, 'cause nothing in the sceenshot would do it, unless the attacker had already replaced cat with a trojan or something.

    [–] flyingSock@feddit.org 21 points 16 hours ago

    chroot, and override exit with an alias,could work

    [–] hperrin@lemmy.ca 7 points 15 hours ago

    AFAIK, there’s no way to without modifying the system tools and shell.

    [–] gegil@sopuli.xyz 5 points 16 hours ago (5 children)

    How can you prevent a shutdown using a power key?

    [–] XLE@piefed.social 11 points 15 hours ago

    There's an Emacs command to do that

    C-x M-c M-minefield

    [–] Unleaded8163@fedia.io 4 points 16 hours ago (2 children)

    You could probably install a handler for the event that's triggered when the power button is pressed. Most OSes do that and pop up a graceful shutdown options window. Most hardware will have a hard shutdown option when you hold the power button for a few seconds. You would probably have to overwrite the BIOS or something at that level to prevent that way out.

    [–] hperrin@lemmy.ca 10 points 15 hours ago

    You could also just unplug it.

    I can think of a way out:

    Just throw the whole PC away. It's someone else's problem now!

    [–] rockSlayer@lemmy.blahaj.zone 11 points 15 hours ago

    But that just becomes a Jumanji issue

    Maybe something like find ./ -type f | xargs md5sum, then avoid the one directory where the executable has a different checksum. Heck, even find | ls might suffice.

    [–] SwingingTheLamp@piefed.zip 11 points 14 hours ago (1 children)

    This could be trivially defeated by a program which erases the hard drive unless run using a particular executable name. Then, all twenty entries could simply be hard links to the same executable file on disk, but one of the names would trigger different behavior.

    [–] tyler@programming.dev 2 points 5 hours ago

    So then you either cat the executable and hope it’s a shell script, you output the binary with a hex viewer and compare, you modify the executable so it’s in a lower permission group and this wouldn’t have access to erase the drive, there’s like a hundred ways to solve this.

    Does it have a perpetual energy source if I unplug it?

    [–] stoy@lemmy.zip 23 points 15 hours ago (2 children)

    There was an old virus that would copy your FAT table to ram, erase it from disk, and preset you with a slot machine UI where you would gamble to get the FAT back, if you won, great, the virus would write the FAT back to the drive, if not, you lost everything.

    Rebooting without playing meant loosing everything.

    [–] RustySharp@programming.dev 14 points 14 hours ago (1 children)

    FAT Table

    Can I just pay? I can go to the ATM Machine and enter my PIN Number

    [–] felbane@lemmy.world 7 points 13 hours ago

    You forget that FAT stands for "File Allocation Travesty."

    [–] khannie@lemmy.world 2 points 9 hours ago

    Diabolical!

    [–] Wildmimic@anarchist.nexus 4 points 15 hours ago

    i had a school colleague who could write small programs in bytecode, so i think someone who really knows their shit can get out without issues with cat and ls, as long as there isn't much obfuscation
