Hacking DHCP Server
Hello Friends,
Today i am going to show you Hacking DHCP server.
What is DHCP Starvation Attack ?
DHCP Starvation is an attack that works by broadcasting vast numbers of DHCP requests with spoofed MAC addresses simultaneously.
If enough requests flooded onto the network, the attacker can completely exhaust the address space allocated by the DHCP servers for an indefinite period of time. Clients of the victim network are then starved of the DHCP resource(s), thus DHCP Starvation can be classified as a Denial of Service attack.
The network attacker can then set up a Rogue DHCP Server on the network and perform man in the middle attacks, or simply set their machine as the default gateway and sniff packets.
This type of attack can easily be achieved with tools such as Yersinia.
Yersinia is a GNU/Linux framework that takes advantage of some of the weaknesses in different network protocols. It can be used for analyzing and testing deployed networks and systems. To use Yersinia for a DHCP Starvation Attack, the following steps may be followed:
Start Yersinia via the command line by typing: yersinia -I.
Select a NIC you wish to use by pressing “i”.
Load DHCP mode by pressing the “g” key, then select DHCP mode.
Press the “x” button to open the attacks menu.
Press “1” to start the attack
