First, we need to have Termux installed and the “Run ADB as Root” developer option enabled.

Install Termux dependencies

pkg update
pkg install openssl

Generate a random key for your openssl reverse shell setup

openssl rand -hex 48
# we will use "9c951d7c50b2480d19f0e538ca8da1efd8639d87846cf054478fa8bf472c9b9f3c62d6ee69e2aa6b5afdefb771ba041e" as an example but it is recommended to use your own key

Save this scripts in your Termux home

"shserver"

export LHOST="*"; export LPORT="4242"; export PSK="9c951d7c50b2480d19f0e538ca8da1efd8639d87846cf054478fa8bf472c9b9f3c62d6ee69e2aa6b5afdefb771ba041e"; openssl s_server -quiet -tls1_2 -cipher PSK-CHACHA20-POLY1305:PSK-AES256-GCM-SHA384:PSK-AES256-CBC-SHA384:PSK-AES128-GCM-SHA256:PSK-AES128-CBC-SHA256 -psk $PSK -nocert -accept $LHOST:$LPORT
