Recently, many message falsification attacks on WPA-TKIP have been proposed. In these research, methods for satisfying ARP packet, DNS packer, SYN packer, or DHCP ACK packet are discussed. In addition, methods for reducing execution time of the attacks have been proposed. However, most of these researches do not discuss realistic damages caused by these attacks in the real environment. In this paper, we present attack scenarios using the message falsification attacks and implement them. Concretely, we discuss an ARP cache poisoning attack and a DHCP DNS attack. In addition, we propose the method for reducing the execution time of the DHCP DNS attack to the half. |
