To code a client socket, we must bind a port to an IP and set it to listen mode, as follows: import socket host = socket.gethostname() port = 12345 s = socket.socket() # TCP socket object s.bind((host,port)) s.listen(5) In Python, sockets can be written in less than five lines of code.

A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. Sockets in PythonĪ socket is one endpoint of a two-way communication link between two programs running on the network. The second file will run on our target machine and will act to monitor, format, and send keystrokes to the server. One socket will run on our client machine and act as a server to receive data and print it to the terminal. The project in question will use Python and rely on a socket server. Today we will create a keylogger to enhance the understanding of security professionals and ethical hackers. Often it uses email or network protocols to send captured keystrokes to a remote machine, sometimes run by hackers.įiltering through these captured keystrokes, hackers can sometimes find sensitive data such as passwords, credit card numbers, or personally identifiable information. Put in simplest terms, a keylogger captures and records the keystrokes of a target machine.
