to install:

• magic wormhole
• tldr
• rlwrap

sudo apt update --fix-missing && sudo apt install magic-wormhole tealdeer rlwrap

for keyring

-> if there is some kind of keyring error

sudo wget https://archive.kali.org/archive-keyring.gpg -O /usr/share/keyrings/kali-archive-keyring.gpg

information gathering

nmap

for quick scan of available ips

nmap -sn ip/24

to filter output for open ips

nmap -sn 192.168.1.0/24 | grep "for " | awk '{print $5}' > ips.txt

scan open ports

nmap -sCV -A -p $(nmap 192.168.1.155 -p- | grep open | awk -F '/' '{print $1}' | tr '\n' ',' | sed 's/.$//') 192.168.1.155 

TTY Spawn Shell

Often during pen tests you may obtain a shell without having tty, yet wish to interact further with the system. Here are some commands which will allow you to spawn a tty shell. Obviously some of this will depend on the system environment and installed packages.

Python spawn shell

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

Fully Interactive TTY

All the steps to stabilize your shell

The first step:

python3 -c 'import pty;pty.spawn("/bin/bash")'

Which uses Python to spawn a better-featured bash shell. At this point, our shell will look a bit prettier, but we still won’t be able to use tab autocomplete or the arrow keys.

Step two is:

export TERM=xterm

This will give us access to term commands such as clear.

Finally (and most importantly) we will background the shell using

Ctrl + Z

Back in our own terminal we use

stty raw -echo; fg

This does two things: first, it turns off our own terminal echo which gives us access to tab autocompletes, the arrow keys, and Ctrl + C to kill processes

OS system spawn shell

echo os.system("/bin/bash")

Bash spawn shell

/bin/sh -i

Perl spawn shell

perl —e 'exec "/bin/sh";'

Ruby spawn shell

ruby: exec "/bin/sh"

Lua spawn shell

lua: os.execute("/bin/sh")

IRB spawn shell

exec "/bin/sh"

VI spawn shell

:!bash

VI(2) spawn shell

:set shell=/bin/bash:shell

Nmap spawn shell

!sh
