Wireshark is an open source software used to analyze computer networks. One of the most notable features of Wireshark is its ability to sniff. Sniffing is a technique used to monitor and analyze network traffic. In this article, we'll cover how to sniff with Wireshark.
If you don't know what Sniffing is, you must read this article: Explanation of Sniffing
What is Wireshark?
Wireshark is an open source software used to analyze computer networks. This software can capture data packets passing through the network and displays information about those packets. Wireshark can be used on a variety of operating systems, including Windows, Linux, and Mac OS X.
Install Wireshark
The first step to sniffing with Wireshark is installing the software. You can download the latest version from the Wireshark official website. After downloading the software, install it as usual.
Run Wireshark
After installing Wireshark, open the software. Once the software is open, you will see a list of network interfaces available on your computer. Select the network interface you want to use for sniffing. For example, on the wifi network stalls, cafes, neighbors etc.
After selecting the network interface you want to use, you can start sniffing by clicking the "Start" button in Wireshark. Wireshark will start capturing data packets passing through the network interface you selected.
Analyze and Filter Sniffing Results
Once Wireshark starts capturing data packets, you can analyze the sniffing results. Wireshark will display a list of captured packets and detailed information about each packet. You can use Wireshark filters to narrow your sniffing results and focus on certain packets. For example, such as looking for passwords, usernames or other important data.
If someone enters account data and logs in, the data will automatically transfer to Wireshark, for example like below.
For example, try logging into a website using fake data, then look for the package on Wireshark. If the username and password package has been found, it will look like the example below.
It worked, it's pretty easy isn't it. While sniffing can be a useful tool for network administrators, it can also be used by hackers to steal users' private and confidential information. Therefore, it is important to use sniffing wisely and only in the right situations.
That's all the tutorial from me hopefully useful and don't forget to share this article so that other people can also get knowledge.
