Tools: Additional custom tools written in Lua.Wireless: For analyzing Bluetooth traffic.Telephony: For analyzing Voice over IP (VoIP) traffic.Statistics: For applying statistical analysis to network traffic.Analyze: Wireshark’s tools for analyzing network packets.Capture: To control starting, stopping, and configuring packet captures.View: To customize Wireshark’s interface.File: To can open and save files, as well as export packets, TLS session keys, and objects.It consists of several menus you can use to take advantage of Wireshark’s powerful features: Wireshark’s menu bar is located at the top of its interface. This interface is compromised of four components. Once you have captured network traffic or imported a saved packet capture file, you will be greeted by Wireshark’s default interface. Any unsaved capture data will be automatically deleted. To start a new packet capture, select the Start Capture button. Select File > Save As, then enter the location and name of the file under which you want to save this data. This will save the packet capture into a temporary file and allow you to perform your analysis. To stop capture packets, click on the red Stop Capture button. Step 3: Stopping the packet captureĭouble-clicking on the capture interface you want to capture traffic to start capturing packets. The line to the right of the interface indicates the network traffic flow passing through that interface. Step 2: Select a network interface to capture traffic onįrom the welcome screen, select which of your network interfaces you want to capture traffic on. Wireshark’s welcome screen will greet you. Wireharsk comes pre-installed on Kali Linux, so to capture network traffic in Wireshark, you only need to perform three steps: Step 1: Open the Wireshark applicationįirst, open the Wireshark application by clicking on the icon. Let’s look at how to capture network traffic. To use Wireshark, you can capture network traffic or upload a packet capture ( pcap) file. Using Wireshark's built-in features, you can perform statistical analysis on this data, follow TCP streams, read sensitive information, extract full files, and much more. The tool supports many network protocols and can transform network packets into human-readable data. However, its most powerful feature is its ability to perform network protocol analysis. Wireshark should be used whenever you need to analyze network packets and understand the network communication happening across a network. To learn more about sniffing, read What Is Arp Spoofing and How Does It Work? A Novice’s Guide. You can set your capture interface to promiscuous mode and use Wireshark to perform sniffing. Sniffing involves capturing network packets traveling across the network that are not intended for your machine. It is commonly used to troubleshoot network problems or perform blue team activities. Packet capture is when you record the network packets traveling across the network to and from your machine. Wireshark can be used for packet capture or as a packet sniffer. Wireshark lets you do all these things and more! Let’s find out how. It allows you to perform blue team activities (such as detecting a cyber attack, analyzing malware, and collecting forensic evidence) and red team tasks (like stealing sensitive information, extracting files, and testing your malware’s network communications). Customization: You add functionality or customization to Wireshark through its plugins.Īnalyzing network traffic is crucial in cyber security.Network traffic statistics and visualizations: Wireshark provides statistical data and visualizations of network traffic.Network packet reconstruction: Wireshark can reconstruct network packets to display application-level protocols so you can see web pages, images, or other application data.Packet filtering: Wireshark includes powerful display and capture filters that filter network traffic.Protocol analysis: Wireshark supports the decoding and analyzing of over 3000 network protocols so you can understand their structure and content.Packet capture: Wireshark can capture traffic using your network interface.
