Port 23 is the traditional port used for Telnet. Telnet is basically a protocol to allow a user to connect to another computer or server in order to view information or log in. When this port is open, it is often an indication that a malicious piece of software has planted a backdoor in your computer to allow other users to access it without your permission.

∙ 14y agoPort 23 is a TCP port traditionally assigned to a telnet daemon. Telnet is a simple protocol used a long time ago for a computer to log into a Unix server or mainframe. You would open a telnet connection to the server, and it would respond with a login prompt. After logging in, you could run programs and make changes to the Unix server. Telnet fell out of common use because it was fairly easy for someone to see your username and password when you sent them.
