An Introduction to WiFi Deauthentication

In the most basic of terms, WiFi deauthentication is the process of breaking the connection between a user and a wireless network.

This can be done either by the user or by the network itself.

There are a few different reasons why someone might want to deauthenticate a user from a WiFi network.

In this article, we’ll explore a few of those reasons and talk about how WiFi deauthentication works.

WiFi Deauthentication

One common reason why someone might want to deauthenticate a user from a WiFi network is if that user is violating the terms of service for that network.

For example, if a user is accessing inappropriate content or using too much bandwidth, the network administrator may decide to break their connection.

Another reason why someone might want to deauthenticate a user from a WiFi network is if they are trying to access a protected resource that they are not authorized to access.

In this case, deauthenticating the user is a way of protecting the security of that resource.

So how does WiFi deauthentication work?

There are actually two ways to deauthenticate a user from a wireless network – through software and through hardware.

The most common way to deauthenticate a user is through software. This can be done using tools like Aircrack-ng or MDK3.

These tools send special “deauth” packets to the target device which cause it to disconnect from the wireless network.

Deauthenticating a user through hardware is a bit more complicated and requires some special equipment.

The first thing you need is an 802.11 wireless card which supports “monitor mode.”

Once you have that, you need to use special software to put your card into monitor mode so that it can listen in on all of the traffic on the wireless network.

Once your card is in monitor mode, you can use tools like Aireplay-ng or MDK3 to send “deauth” packets to the target device and break its connection to the wireless network.

Conclusion

Whether you’re an administrator who needs to enforce your network’s terms of service or you’re trying to protect sensitive data, knowing how to perform WiFi deauth can be a valuable skill.

In this article, we’ve given you an introduction to WiFi deauth – how it works and why someone might want to do it.
