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".

Well yeah? And you do it in a vm. But seems like a decently simple problem anyway. ls -al and compare the sizes.
Obvioulsy whoever set this minefield thought about this
I mean they didnβt, cause you can just open another terminal window or pull the plug on the computer, but like someone else said, a binary canβt change the directory for you cd is a shell built in, so Iβm pretty sure this would be trivial to get past.
The power cable would like to have a word.
it removed your disc encryption keys and the only way to recover it is finding it in memory through the minefield
\cd ~
what does this change?
Bypasses aliases and uses the original command
When people don't know normal things we learned in '92, I get worried.
Instead of acting like an asshole, teach us.
Oof. I consider myself a fairly decent Linux Sysadmin (~15 years experience ~10 years professionally) but I actually didn't know about that. :/
Combat the minefield with a fork bomb. Ainβt no process surviving this engagement.
They never guess the next move: Unplugs pc
loud knocking on the door
Either that or the PC keeps running anyway.

How can you prevent users from leaving a directory?
chroot, and override exit with an alias,could work
Magic, I guess, 'cause nothing in the sceenshot would do it, unless the attacker had already replaced cat with a trojan or something.
AFAIK, thereβs no way to without modifying the system tools and shell.
How can you prevent a shutdown using a power key?
There's an Emacs command to do that
C-x M-c M-minefield

Reminder that binaries cannot change a shell's working directory, so the non-mines will do nothing.
(cd is a shell builtin)
Technically they could if run as root by modifying the parent process

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.
There goes my night? Longer?
Cool! Will give this a try for sure! Always forget commands
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!

I can think of a way out:
Just throw the whole PC away. It's someone else's problem now!
But that just becomes a Jumanji issue

What did the minefield directory do here to hijack cd?
Can an alias be applied upon cd?

We have squid games at home.
Squid games at home:
objdump -D * | less
Iβll hit them with an rm /etc. We go out, we go out together and on my terms.
Has "let's play a game" vibes
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.
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.

Does it have a perpetual energy source if I unplug it?
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.
FAT Table
Can I just pay? I can go to the ATM Machine and enter my PIN Number
You forget that FAT stands for "File Allocation Travesty."
