It is a pain when you make a typo in your reverse shell and then accidentally close the shell with CTRL+C. It’s also a pain because:
- It has no arrow-up
- It has no tab-completion
- It is just uncomfortable!
In this post, I’ll share a quick tip to make your reverse shell a bit comfortable to use, it’s almost like SSHing the machine!
Step 1: Spawn a TTY shell!
First, we need to upgrade our current non-TTY shell into a TTY shell using the common Python PTY module.
$ python -c "import pty; pty.spawn('/bin/bash')"
$ python3 -c "import pty; pty.spawn('/bin/bash')"
Visit this web for alternative if there’s no python installed in the machine. I also found another way using
script just after I published this post.
$ script /dev/null -c bash
Step 2: Upgrade to Full Interactive Shell
Background the process using CTRL + Z, and then type:
$ stty raw -echo
Once done, type
$ fg (you won’t be able to see what you type, but don’t worry) to bring the shell back to foreground and hit enter two times or just use
$ stty raw -echo;fg
Now you should be able to use arrows key and tab completion in the shell.
Since normal Ctrl + C won’t close this shell, you have to kill its process or just type
If your shell prompt is messed up after exiting, type
$ stty sane.
Note: It won’t work with
