Like Kismet, KisMac performs passive network monitoring and can attempt to crack WEP and WPA keys using brute force password guessing or exploiting known flaws in legacy protocols. KisMac, as its name suggests, is designed to be a Kismet clone available on macOS. It passively collects packets to identify both broadcasting and hidden wireless networks. Kismet is available on all operating systems and can run using any Wi-Fi card that supports radio frequency monitoring mode (RFMON). It is a network sniffer capable of monitoring 802.11 wireless traffic as well as other wireless protocols, such as Bluetooth and Zigbee. Kismet is one of the most famous Wi-Fi hacking tools available. A few different tools provide network discovery functionality to help with identifying wireless networks and extracting useful traffic for use in an attack. *Note: IP’s have been randomized to ensure privacy.Before attacking a wireless network, it is necessary to know that it exists. Download example PCAP of HTTP Flood attack Ip.flags = 0X01 – will show IP Fragmented packets. “ip” filter – will show all IP related packets. “Image 3 – IP Fragmented Flood stats”Īnalysis of IP Fragmented Flood in WireShark – Filters The average packet size is considered small. “Image 2 – IP Fragmented Flood Flags”Īs seen in Image 3 the capture analysed is around 8.5 seconds and the average number of packets per second is around 1065 (considered high), with a rate of around 0.42 Mbps. Bit 2: (AF) 0 = Last Fragment, 1 = More Fragments. Bit 1: (AF) 0 = May Fragment, 1 = Don’t Fragment. The more fragments field needs to be set to 1 as seen in image 2. The packet can be identified as a part of a fragmented data frame by its Flags field. Image 2 displays an example of IP Fragmented packet. Technical analysisĪs you can see in Image 1, the attacker (IP 10.0.0.2) sends to the target (IP 10.128.0.2) a large amount of Fragmented IP Protocol packets. IP fragmentation is the process of breaking up a single Internet Protocol (IP) packet into multiple packets of a smaller size. Generally this flood is used as a basic but effective flood to bring down perimeter devices or saturate bandwidth. IP Fragmented Floods are generally spoofed attacks and normally come at a very high rate and in most cases have no identifiable Layer 4 protocol, but just garbage and the packets have to be reassembled by various devices along the way. IP Fragmented Flood is a DDoS attack aimed at consuming computing power and saturating bandwidth, they may also crash devices in rare cases because of buggy packet parsing.
