Well ! Sometimes it happens like a single router/DHCP server is available at the location and many user get connected to that, in such cases the surfing speed is not so good. And obviously what we actually think “Somehow I can disconnect everyone and utilize the whole Wi/Fi router speed for my surfing.” But can’t actually perform the blocking of other devices to restrict service of server only for self surfing.
This professionally it is also termed https://somethingelse.com/wp-admin as DHCP Starvation !
Why Professionally it is termed as DHCP Starvation ?
Answer is quite simple. GO through The Hacking Grammar.
Let’s get back to the topic.
DHCP Starvation is a process of acquiring all the IP’s throughout the whole range provided by the Router/DHCP server. And here we can do this by a small and open source tool known as Yersinia.
What do you actually gonna perform ?
We will install the tool, run it, and grab the whole range of IP that could be served by the DHCP server/Router/Wi-Fi. I prefer to use the Linux and recommend to use the backtrack for this session. Configure the validated Backtrack and open the command prompt. Here it is not recommended to do the practical to harm any system.
Open the terminal of backtrack i.e command prompt.
root@back:~# yersinia -G
And then hit Enter ┘
It will open a prompt window with a GUI(Graphical User Interface).
The last Pop-up asks for how the attack should be ?
Now last but not least, question arises is A single MAC id can have only one Network connectability, but as mentioned above Yersinia tool catches all IP that can be provided, HOW ?
The yersinia itself created as to automatically spoof the MAC address and get the every possible combination
