AirSnort for Windows is an encryption wireless LAN tool used to crack encryption codes in WEP Wifi. It gathers information from 802.11b information from WEP networks. This is done passively by the software where it gathers packets going in and out of the system. of this gathering for packets, it requires around 5 to 10 million. When enough packets have been obtained the encryption has gathered enough information to guess the password. This software does not, however, crack WPA wireless. The amount of time that it will be able to crack and guess a password is under a second. This can be done at any area if the wireless connection is of WEP origin. There are specific cards that are required, however. You will also need to have specific and updated software for AirSnort to work. The system run with aero peek, Winrar, GTK, Glib, Pango, and ATk. Each of this software is essential in having Airsnort work properly and crack wireless passwords in under a second. Managing devices is important to ensuring that that encryptions can't be traced and do no harm to your computer.
This product is free to download online. It requires specific installation instructions and drivers for it to perform properly. The password guessing occurs in under a second but only through WEP wireless systems. This run on a general system for most cracking software of 802.11b. The system can run on Windows and Linux but each requires specific and up to date software. This is easily performed in an area with a WEP wifi and password that needs to be cracked. This free downloaded product can be useful in solving certain wireless internet passwords.
The final step, without getting into every possible patch or scenario that might arise, is to install the AirSnort program. Again, you will need to download and unzip/untar the program to your chosen location. Once complete, you will need to enter the airsnort directory and run the autogen .sh script. This will configure the program, after which you will need to run the ./make all command to compile the program.
Now that you have Snort Wireless up and running, the next step is to configure it for use on your particular network. When ipkg is run, Snort installs itself into the /etc/snort directory on your router. Like all good Unix-based programs, Snort uses an editable configuration file to give it information about its network environment and the different attack patterns that it should look for. This file is called snort.conf (Figure 5) and is located in the /etc/snort directory. Open it up in your favorite text editor (or download the program with ipkg if it is not available on the router by default).
Older versions of Airsnort and other tools that attacked WEP by examininginteresting IVs became unusable as an attack vector against most wirelessequipment produced after 2002. In 2004, Korek released a new WEPstatistical cryptanalysis attack and while still based on the weaknessesin the key scheduling algorithm, the Korek attack removed the requirementfor collection of interesting IVs. This attack has been coded intoseveral tools, most notably Aircrack, WepLab and the newest version ofAirsnort. Each tool functions slightlydifferently, but each requires as few as half as manypackets to break WEP than the previous generation ofWEP cracking tools.
Two of the most popular programs used for actually cracking the WEP key are Airsnort and Aircrack. Airsnort can be used with the .dump files that Kismet provides; and Aircrack can be used with the .cap files that Airodump provides.
The Aircrack-ng website has a list of word lists that we can use. However, I found a much larger list that works as well. You can download a 1,493,677,782 word list that is around 15GB in size from CrackStation. Yes, the site name sounds malicious, but there were no viruses or questionable advertisements on it.
ever before wireless networks become popular, their securities and protections have been frequently questioned. with any of several freely downloadable tools, e.g. air snort, crackers can break into the wireless lans without much difficulty. the main security risks come from the wep encryption scheme. every wep packet is encrypted with a rc4 cipher stream generated by an encryption key. this encryption key is made up of a 24-bit initialization vector (iv) and either a 40-bit or 104-bit wep key, depending on the key length type. in a connection with wep enabled, the 24-bit initialization vector is sent in plain text with the encrypted packet so any cracker can easily see the part of the encryption key. of all the possible ivs, there are approximately 9000 weak ones. they provide additional clues on the total encryption key stream and making the cracking of wep easier. a temporary remedy to this weakness in wep is to change the wep key frequently. generally the key should be changed at least once a week for small office users, and more often for larger networks. however, the design of wep does not take the "key management" into consideration; all wep keys have to be edited manually every time a wep key change is required, and the changes have to be made in every devices in the network, including access points, pcmcia cards, pci cards, etc.
All software media should be backed up regularly to ensure that no data are lost. Periodic backups stored in a secure off-site location will make it possible to recover quickly from a catastrophe on site. The agency should take into account regional peculiarities when storing backups off site. For example, in areas prone to earthquakes, media should not be stored in high-rise buildings; in areas prone to flooding, media should be stored in a facility away from the flood plain. Some recommendations for software security are as follows: store software media in a locked cabinet within a proper environment; retain off-site storage for backups of installation media; test the process for restoring software; retain off-site storage of licensing and application documentation; maintain and back up licensing management and related documentation; allow access to applications through the use of network security settings to only those groups/users that require access; implement a software-auditing package to ensure license compliance and to ensure that no unauthorized software has been installed on the agency's system; standardize applications across the agency; use virus-scanning software with frequent definition updates (network-attached appliances are available for e-mail virus scanning); and use spamming prevention or filtering software to prevent unauthorized entry of email (e.g., do not allow web-based e-mail programs, such as Hotmail?). Unauthorized e-mail entry is a serious vulnerability that can lead to the entry of viruses into the network through a "back door." Securing the Network The same security procedures in place for server hardware apply to equipment that supports the network, including switches, hubs, routers, firewalls, access points, cabling, etc. Network equipment should be installed in an environment with proper ventilation and power requirements and should be protected from unauthorized access. The agency should place the equipment in dedicated building spaces. Access should be limited to staff that have a key, combination lock, key card, or other security device. Some basic precautions for securing network equipment are as follows: limit access to network equipment to authorized individuals; do not allow users to install unauthorized network equipment; use secure, encrypted passwords for "root" access (access to the "root" enables users to control entire systems or servers); and ensure proper cabling and cable protection by running cabling under a false floor, avoiding running cable over fluorescent lighting fixtures, and staying within cable/fiber length requirements. A fundamental action the agency can take toward maintaining a secure and reliable network is to hire a qualified individual to serve as the network administrator. Network administration is not a task for the average high school teacher/technology coordinator. Many agencies, however, cannot afford to hire an experienced network administrator for each school and often do rely on faculty for this position. If a teacher/coordinator is to be responsible for a school network, the agency must recognize training and professional development as priorities. Agency network policies and procedures should be clearly defined. These policies should be made readily available to anyone responsible for maintaining the network. Listed below are some items to consider for agencies managing their own networks. The responsibilities of a network administrator are, for the most part, very technical in nature. This reinforces the point that training is critical for anyone with the responsibility of running a network. Agencies should assign one individual to be responsible for network administration (and one individual as his/her backup); limit access to network equipment console screens by login credentials (either on the piece of network equipment or using an authentication server); limit access to Telnet sessions on network equipment through access lists and/or authorized workstations where only authorized users have access; limit protocols running on the network equipment; configure login banners to warn intruders of possible prosecution; use firewalls to prevent unauthorized access between external and internal systems; use unroutable IP addressing schemes within the internal network [Class A - 10.0.0.0-10.255.255.255 (10/8 prefix), Class B - 172.16.0.0-172.31.255.255 (172.16/12 prefix), Class C - 192.168.0.0-192.168.255.255 (192.168/16 prefix)]; utilize intrusion detection systems (IDS); inspect, analyze, and maintain router audit logs; provide ingress and egress access control list (ACL) filtering to prevent IP spoofing; and eliminate unauthorized network resource use by monitoring network traffic and bandwidth usage and protocols to ensure adequate bandwidth for applications; removing the ability to download unauthorized files; restricting remote access to network resources to authorized individuals with types of remote access including dial-up connections, virtual private networks (VPN), and Point-to-Point Protocol (PPP); implementing a multiple-authentication policy for authorized users or integrating into an authentication server; eliminating any "back-door" types of equipment (e.g., user modems installed on desktops); maintaining proper encryption of remote connections to ensure confidentiality; and using VPN technology with proper encryption to gain connectivity through the public networks such as the Internet. Wireless Networks Wireless communication is a rapidly evolving technology that is becoming increasingly prevalent in everyday life. The built-in security for wireless computer networks, however, is relatively weak. Technology coordinators need to pay particular attention to secure these networks properly, and the network administrator must keep up to date on emerging methods for securing wireless networks. Some security measures to consider when planning a wireless network are as follows: shut off Service Set Identifier (SSID) broadcasting and use an SSID that does not identify the agency by name; select a hardware vendor and software revision that has fixed the problem of randomization of initialization vectors (IVs); utilize applications like AirSnort or BSD-AirTools, which will be less likely to crack the agency's Wired Equivalent Privacy (WEP) keys; use 128-bit WEP and change WEP keys regularly. Select a vendor that provides a tool to rotate the agency's WEP keys; disallow access to resources at the first router hop other than the agency's VPN server, which ensures that the only host available to the wireless segment is the VPN server until a tunnel is established; place wireless access points on a dedicated virtual local area network (VLAN). Do not mix wired and wireless clients on the same LAN segment; implement a policy that limits the amount of connectivity a wireless client has to the agency's network. Assess whether students/faculty/staff need more access than TCP/80, TCP/443, etc.; utilize personal firewalls on the agency's workstations; and disable automatic IP address assignment (DCHP). If hackers are able to guess or crack the agency's WEP keys, they will not be able to access the remainder of the internal network because VPN and VLAN architecture with access lists will allow only authorized VPN clients to be routed to the network from a wireless VLAN segment. Hackers will be able to attack clients on the same subnet, however, and if one VPN connection is left up, it could be abused to access the rest of the internal network. back to top 2b1af7f3a8
