Upgrade to a full tty shell

In ctf after you get a shell you may want to see if you can upgrade to a full tty shell. You can find many ippsec videos on youtube doing this.

First see if there is python or not

$ which python

If it is available, type following command to get bash shell. There is another post on how to escape restricted Linux shell.

$ python -c 'import pty;pty.spawn("/bin/bash")'

Now, if you also want tab auto completion Ctrl-Z to background your shell and type on your box

$ stty raw -echo

then type ‘fg’ to resume the shell and finally if you want to be able to use commands like ‘clear

$ export TERM=xterm-color

 

if only python 3 is installed, use python3 -c

There are plenty other ways to do this. You can always google to find it.
