Hey there! We can describe Netcat as a penetration testing tool, or networking Swiss army knife and if you ever dabbled in this field then chances are that sometimes somewhere every pen tester must have used it.

It’s an incredibly useful tool that has been around for many years and is broadly used for Network Troubleshooting to Security Exploitation.

So, what exactly is Netcat? A network daemon that reads and writes data across network connections using the TCP/IP protocol.

It is basically your basic setup for simple connections, file transferring, port scanning, or even some primitive chat systems. Being lightweight, it can be used easily and installed in Linux, Windows, or macOS without any frills.

Why use Netcat?

Well, it’s like having a multi-tool in your pocket—except for your network. You can use it to:

• Test connectivity and troubleshoot network issues
• Scan open ports and identify potential vulnerabilities
• Transfer files quickly between devices
• Set up basic servers or clients for testing
• And yes, even play
