Comparison of Wireless Network Penetration Testing Tools on Desktops and Raspberry Pi Platforms
Comparison of Wireless Network Penetration Testing Tools on Desktops and Raspberry Pi Platforms Aparicio Carranza, PhD1, Daniel Mayorga, BTech1, Casimer DeCusatis, PhD2 and Hossein Rahemi, PhD3 1New York City College of Technology - CUNY, Brooklyn, NY USA, [email protected] 2Marist College, Poughkeepsie, NY USA, [email protected] 3Vaughn College of Aeronautics & Technology, East Elmhurst, NY USA, [email protected] Abstract– Wireless networks have become ubiquitous due to their transparent mode to capture packets in the 2.4 GHz band from ease of use and facilitation of mobile devices such as smart phones, a Netgear router [6]. We set up a WLAN for testing using a tablets, and various Internet of Things (IoT) applications. This has standard commercial dual band Cisco wireless router; driven a need for more advanced wireless penetration testing although our testing was conducted in the 2.4 GHz band, this techniques, and for more technical professionals trained in wireless work should be readily extensible to the 5 GHz band. Our security. In this paper, we investigate three popular open source wireless penetration testing tools (Aircrack –ng, Reaver, and Kismet) wireless router supports Wi-Fi Protected Setup (WPS) for and compare their behavior on a traditional desktop computer and testing with Reaver, and configuration options for WEP, a Raspberry Pi model 3. Use cases include packet sniffing and WPA, and WPA2 encryption [7-10]. While we recognize that decryption of WEP, WPA, and WPA2 passwords. Based on this WPS contains a known vulnerability and is not recommended work, we make recommendations for using specific tools in for sensitive applications, and that likewise WEP and WPA cybersecurity training and education. -

Kismet will work with any wireless card which supports raw monitoring mode, and can sniff 802.11a, 802.11b, 802.11g, and 802.11n traffic. The program runs under Linux, FreeBSD, NetBSD, OpenBSD, and Mac OS X. The client can also run on Microsoft Windows, although, aside from external drones (see below), there's only one supported wireless hardware available as packet source. Distributed under the GNU General Public License,[2] Kismet is free software. Features[edit] Traditional Lipsticks, Liquid Lipsticks, Matte Lipsticks, Lip Plumping Glosses, Lip Liners and More! Showing 1–21 of 70 results. Rated 5.00 out of 5. CEO Semi-Matte Lipstick $ 18.00 Add to cart. Yours Truly Semi-Matte Lipstick $ 18.00 Add to cart. Sweetie Semi- Matte Lipstick. Two files stored in the /etc/kismet directory called 'apmanuf' and 'clientmanuf' are used to help Kismet determine the types and manufacturers of AP or wireless clients based on MAC. KisMAC is an open-source and free sniffer/scanner application for Mac OS X. It has an advantage over MacStumbler / iStumbler / NetStumbler in that it uses monitor mode and passive scanning. Kismet differs from other wireless network detectors in working passively. -

Only when I fall do I get up again”. - Vincent van Gogh © Ekhator Stephen Aimuanmwosa, (BTH) Karlskrona January, 2010 Email: [email protected] ii Evaluating Kismet and NetStumbler as Network Security Tools & Solutions ABSTRACT Despite advancement in computer firewalls and intrusion detection systems, wired and wireless networks are experiencing increasing threat to data theft and violations through personal and corporate computers and networks. The ubiquitous WiFi technology which makes it possible for an intruder to scan for data in the air, the use of crypto-analytic software and brute force application to lay bare encrypted messages has not made computers security and networks security safe more so any much easier for network security administrators to handle. In fact the security problems and solution of information systems are becoming more and more complex and complicated as new exploit security tools like Kismet and Netsh (a NetStumbler alternative) are developed. This thesis work tried to look at the passive detection of wireless network capability of kismet and how it function and comparing it with the default windows network shell ability to also detect networks wirelessly and how vulnerable they make secured and non-secured wireless network. -
Wi-Fi Monitoring & Kismet
Wi-Fi Monitoring & Kismet Mike Kershaw @KismetWireless Sharkfest 2019 Intro ● Wi-Fi sniffing has been around since the late 1990s ● Still something we need to do now… ● More and more “last-mile” is going to wireless ● More and more sensors, control networks, etc are going to wireless ● Offices are increasingly using Wi-Fi instead of running cable ● BYOD (Bring Your Own Device) is huge ● Plenty of security problems need monitoring Get off my lawn ● Kismet is over 18 years old now ● I used to joke it was old enough to drive. Now it’s old enough to buy cigarettes and vote. ● Undergone several significant rewrites over that period ● Most recent major rewrite in the last few years adds all new capabilities, user interfaces, etc ● More on this later though... Why do we need something special? ● Why do we even need another tool just to monitor Wi-Fi ● There’s already so many that monitor packets ● Maybe have heard of one or two ● Rhymes with “Tire Bark” ● I heard there’s some sort of conference about it? Wi-Fi is a unicorn ● Truly shared medium. Anywhere signal goes, it impacts something ● Not just shared media with your network, but shared with everyone near you ● Multiple networks overlap bandwidth and channel access ● Isn’t Ethernet. Your OS might act like it is. It isn’t. ● Remember the OSI model? You’re suddenly really going to care about layer 1 and 2 more than you ever did before. ● Knowing a network is there is not knowing what’s going on with the network ● Knowing what’s impacting your network is not simple! Discovering Wi-Fi networks ● Several techniques can be used to discover Wi-Fi ● Scanning mode: looks for advertising networks; can’t see clients, but does a good job showing what access points are out there.
