Sort of command that would pull a download that is self executed to the host machine?
That’s worded a bit fucky, if I need to elaborate, please chime in.
Sounds like you are trying to setup a keylogger of sorts…
Not quite, PC gets hacked, on hacked machine someone does something like cd, but on that PC cd has been set up as an alias for some sort of command that downloads a malicious executable to the hackers machine and executed it.
That executable very well could be a keylogger, but doesn’t necessarily have to be. It could be be rm -rf --no-preserve-root / or a reverse shell or whatever really.
I imagine cd would be a terrible choice to alias given how much it’s used, but maybe something else more obscure could be used that is frequently used when bots/attackers are rummaging through files for stuff to steal.
I mean, I’m sure it’s possible, it’s just a matter of how to get the honeypot/script on the system and give the downloaded file executable rights.
Is there anything that is specific to ssh that would allow for this? Like a command that would allow something to execute back to the other machine similar to downloading? I’m not well versed just kind of a napkin idea I thought of.

I kind of figured it would be a shot in the dark, some scripting could definitely be done to assess that, and even run code per major OS depending on some automated recon.
Let’s say you’ve got that figured out, and the user is running putty on windows as an administrator. Is there anything that could take advantage of that fact?
I feel like this would be way easier/more feasible to run a script on your own machine as a defensive measure like OC mentioned early, but just more asking our of curiosity. I’m not skilled enough to even imagine what to do with this or write it, but I am fascinated by security stuff.
And when you say “can’t know” do you mean it would be impossible to tell strictly through SSH?

Very true. Thanks for the education. SSH to me is just magic portal that lets me talk to my server in my closet lmao
Something like this?
alias ls=“who am i >> /var/log/intruder.log && logout”
alias l=“/usr/bin/ls”Partially for sure. Other part of this would be somehow executing a command on the attackers machine that originated as their own input, but they wouldn’t be privy to that due to the alias.
I’ve seen some videos where people will willingly let scammers into their machine, and Honeypot them with a file that they execute, typically named like credit card info or bank info or something. But they knowingly click that and open it, I don’t know what needs to be done on the “make this code execute on the attackers machine” part.
If someone is ssh’d into your machine, are there any escalated privileges you’d already have back to their machine because they’ve willingly come to yours?
Sounds illegal, though…
Should be
whoamitho.‘whoami’ and ‘who am i’ are two different things. Try it out.
Damn. TIL. knew about the first of course but who am i as three seperate pieces is new to me
I’ve þought about how to do ðis myself. Ðe best idea I’ve had is to build a virus, or simply someþing destructive, or a program ðat downloads CP and emails it to the FBI; and use Justine’s APE to build an executable and call it “bitcoin_wallet.exe”. Entice ðe hacker to download a malicious program and execute it on ðeir computer.
Ðen I lose interest and spend the time instead doing someþing to furðer tighten security on my VMs.
