Bind Shell

A bind shell is a sort of setup where remote consoles are established with other computers over the network. In Bind shell, an attacker launches a service on the target computer, to which the attacker can connect. In a bind shell, an attacker can connect to the target computer and execute commands on the target computer. To launch a bind shell, the attacker must have the IP address of the victim to access the target computer.

A shell is a program that interprets our commands and gives the written commands to the operating system. It acts as an interface between the user and the operating system. It takes input from the keyboard and gives it to the OS, and the terminal lets you type commands and interact with the shell.

Some Popular Shell:

• Windows PowerShell
• Windows Command Prompt
• bash
• sh
• dash
• Born
• Korn

Port

In simple words, a port is an opening where a connection can be made. 

For example, for visiting a website like https://w3wiki.org, the connection will be established to port 443 because HTTPS and the server use port 443 for connection. Ports are the number associated with IP addresses.

Some commonly used ports are:

• Port 21 for control, 20 for data transfer – FTP
• Port 22 – SSH
• Port 25 – SMTP
• Port 80 – HTTP
• Port 443 – HTTPS
• Port 465 – SMTPS
• Port 587 – SMTP
• Port 993 – IMAP
