Wireshark is a fantastic program because it's well-supported. This can allow us to be even more specific in our search, while still making sure the packets are in the capture file and available for analysis. With these, we can choose which packets from our capture will show up and which will be hidden. The last way we'll organize our view in Wireshark is with display filters. We can also instantly tell the difference between someone using a program that utilizes deauthentication packets exclusively versus a mix of deauthentication and disassociation, as in MDK3. This will make packets with specific rules we designate as important stand out more visibly. The next way we can organize information is to tag interesting packets with color codes. By not saving these packets in the first place, you can reduce the size of your capture file and avoid seeing the distracting and irrelevant information. This can be packets from another AP or just data packets we have no reason to save. The first is by simply dropping packets that aren't relevant to what we're looking for. Wireshark comes with a number of ways to filter what we're seeing to be more relevant. To sort through these, we'll use a few custom options in Wireshark. Once you set the channel to a network you want to scan, Wireshark will display all the packets captured on the channel, including other access points (APs) operating on the same channel. While scanning, Wireshark will not control your wireless network adapter, so you'll need to use another program to set the channel (or to scan through channels). To make sense of it, we'll need to organize and filter it. As you can see from below, even with some coloring rules, a normally functioning Wi-Fi channel has a tremendous amount of information flying around.

Wireshark can quickly get overwhelming with the amount of information it displays, so we'll need to filter this down to make it useful. In this example, we'll be using Wireshark to detect Wi-Fi jamming attacks from nearby script kiddies. While Kismet doesn't offer as much information as Wireshark, it's also a great way to get visibility of any attacks going on in your area. Kismet provides an alert for such attacks under the 'Alerts' section, as well as providing alerts for other types of frequent attacks. Other tools for detection can also identify these attacks in progress.

To get started detecting these attacks, we'll be using Wireshark to sniff packets in the area and separate the types of packets we're interested in with filtering.

Software like Wireshark can be quite overwhelming for a beginner, especially without knowing what you're looking for in the flood of information available.

While these script-kiddie attacks can be very disruptive, they can also be detected by a variety of free and open-source tools.

Doing so requires only a wireless network adapter which can be put into monitor mode, and a simple command can take out an entire channel with many networks operating on it for up to a block without any specialized equipment. Most common scripts like Aireplay-ng or MDK3 do this by flooding a target with deauthentication or disassociation packets, which are both normal-seeming packets which have a disruptive effect on the network. Tools to do this are free, widespread, and well-documented on the internet, all perfect for script kiddies. Because the management packets that devices use to control these connections are unencrypted, it's easy for an attacker to craft fake ones after sniffing the wireless channels nearby.

Most denial-of-service (DOS) attacks are pretty basic and take advantage of well-documented flaws in the way WPA networks manage connections. We'll use Wireshark to discover a Wi-Fi attack in progress and determine which tool the attacker is using. The ease with which these common tools can jam networks is only matched by how simple they are to detect for anyone listening for them. Due to weaknesses in the way Wi-Fi works, it's extremely easy to disrupt most Wi-Fi networks using tools that forge deauthentication packets.
