Computer Security and Forensics Tools Wireless Security

Question: Describe about the Report of Computer Security and Forensics Tools for Wireless Security. Answer: Executive Summary: This report about Wireless Security Cracking tools covers all the aspects related to it. The report covers various types of attacks related to wireless security such as Confidentiality attacks, Integrity attacks, Authentication attacks and Bluetooth attacks. There are some tools related to these attacks which have been explained separately in this report. In the end, various wireless security cracking tools have been compared. So, this report helps reader to get knowledge about various security cracking tools. Introduction: This report is an analysis of wireless attack tools which emphasize mainly on 802.11 networks and Bluetooth. In this four types of attacks are included which are Confidentiality, Integrity, Authentication and Bluetooth. Confidentiality attack tools emphasize on the type of data and known for cracking the encryption. Integrity attack tools mainly emphasize on the data which is in transmission and in this, frame insertion, main in the middle and replay attacks are included. Authentication attach tools emphasize on crackin the authenticity of the data i.e. cracking the passwords, crackin the keys and credentials. Last but not the least, Bluetooth attack tools focus on attackin the Bluetooth devices and attempt to steal the information from the device with the help of Bluetooth connection. So, various hacking and cracking tools used for these purposes are discussed in this report. The tools have been compared on the basis of its purposes, availability, encryption type, authentication typ e, and data integrity type. Wireless Security Cracking Tools: Usually, Wireless networks come with a great security such as Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA). Wireless Security is must to ensure confidentiality, privacy, availability, authenticity and integrity of the data. There are some kinds of attack which attack on the security of wireless networks are as follows: Confidentiality Attacks: These are the types of attacks which attempt to intercept the confidential or private data over wireless networks. Integrity Attacks: These are the types of attacks which try to send fraudulent control, data frames so that recipient gets mislead. Authentication Attacks: These attacks are basically used by the intruders for stealing the identities and credentials of users so that they could access private networks. Bluetooth Attacks: Nowadays, attacks on Bluetooth are also emerging with growing popularity of Bluetooth devices. Bluetooth attacks are DoS, Bluesnarfing and Bump attack. In Bluetooth DoS attack, a device is involved which is not a part of piconet interrupting the existing piconet of other devices. Bluesnarfing is an attack in which an attacker might get unauthorized data with the help of Bluetooth Connection. In Bump attack, attacker sends a request to the victim for accepting the connection for data transfer like photos, calendar notice or contacts on a PDA. Once the data is sent, attacker does not close the connection i.e. keeps the connection open due to which attacker is allowed for requesting key regeneration even after the victim deletes the pairing between them. Once the attacker is done with key regeneration, he/she may be able to access all the services of victims device. To attacks on Security of Wireless Networks, some tools have been built up which try to crack the security of networks. Some of tools have been developed for compromising with 802.11 networks. Therefore, these kinds of tools are known as Wireless Security Cracking Tools. Wireless Security Cracking Tools have been categorized as follows: Confidentiality Cracking Tools: Eavesdropping is an attack to intercept the real-time private communication such as instant messages, phone calls, or videoconferences. Tool used for such attack is Wireshark which is used to display the network traffic of both wireless and wired networks. This tool is used to show the captured data in an easy way so that anyone could read and follow it easily. An encryption key cracker is a tool which is used to crack the encrypted information. There is a tool called AirSnort for WEP and AirCrack for WPA. Integrity Cracking Tools: Airpwn is a kind of wireless attack tool for packet injection of 802.11. File2air is also a similar type of tool but using this tool, user is allowed to specify an amount of injected packets. There is one more tool called as AirJack which is used to run the actual frame injection. Simple replay is an attack tool which allows for 802.11 packets which had been captured to be injected back into the network. Frame injection and frame relay attacks tools are the tools which attack directly on the integrity of data. Availability Attack Tools: Few of the availability tools are similar to those listed in the integrity attack tools because most of the attacks are similar in both availability and integrity. But there are some specific tools which are used to attack availability because few of the attacks on availability are different from that of integrity. FakeAP is one of the flooding attack tools which are used for generating thousands of 802.11. Bluetooth Attack tools: With the growing demands of Bluetooth devices, risk associated with Bluetooth i.e. attacks on Bluetooth are also growing. A BlueSmack tool is used for launching the ping of death attack on Bluetooth devices. This tool requests thousands of echoes from a Bluetooth devices and then the device gets unable to do anything only the echoes are returned which causes Denial of Service (DoS). BlueChop and BluePass are also attacks tools for DoS. BlueChop is used to interrupt the existed piconet. BluePass attack tool is used for creating Bluetooth packets so that buffer overflow attack is caused. Wireshark Tool: This tool is basically a confidentiality attack tool which is also known as Ethereal and considered as the most powerful tool in network analysis toolkit. It works as a network packet analyzer which is peered inside the network and used to analyze the details of traffic at various levels. This tool is free of cost. It is much easier to install this tool. It can run on various platforms such as Windows, Macintosh OS X, Unix/Linux or any other operating systems. Ettercap Attack Tool: Ettercap is a free and open source tool which is used to launch the Man-in-Middle Attacks. This tool is used for the analysis of network and security auditing. It is run on various operating system platforms such as Linux, Windows, Mac OS, and BSD. Ettercap attack tool sniffs the captured passwords and network traffic. AirCrack Wireless Password Cracking Tool: Aircrack is a very famous tool developed by Thomas d'Otreppe de Bouvette and used for cracking the passwords of wireless networks. This tool is basically used as 802.11 WPA-PSK and 802.11 WEP keys cracking tools across the world. Firstly, this tool captures the network packets and then it attempts to crack the password by analyzing those packets. This tool is considered as the most powerful tool. In this tool, a console interface is offered. It can be run on various operating systems such as Linux, FreeBSD, OS X, OpenBSD and Windows. It is free of cost and can be downloaded from the internet. Fern Wi-Fi Wireless Cracking Tool: Fern Wi-Fi Tool is also one of the best tools which are used for network security. It is used to identify real time network traffic and hosts. The purpose of development of this tool was to identify flaws in computer networks and then fixing them. This tool can run on Apple, Windows and Linux Operating system platforms. With the help of this tool, WEP/WPS/WPA keys can be cracked very easily. Since this tool is in active development, one can get updates of new features on regular free. This tool has free access for a very limited period i.e. for 7 days, after that user has to purchase it for some cost. WepAttack tool: WepAttack is an open source tool for Linux for cracking the 802.11 WEP keys. This tool works by performing an active dictionary attack by doing test on millions and millions of words to find the working key of the network. To work with WepAttack, only a working WLAN is required. This tool runs on the Linux operating system platform. The software is free of cost and licensed under the GNU General Public License as published by the Free Software Foundation, either version2 or any latest version. CloudCracker tool: CloudCracker tool is an online password cracking tool for hacking the password of WPA protected wi-fi networks. This tool is used for hacking the various password hashes. Working of the tool is very easy. One is require to upload the handshake file, enter the name of network and start the tool. The tool may contain large dictionary of around 300 million words for performing dictionary attacks. To access this tool, one has to visit its official website which is www.cloudcracker.com. There is no need to download any software to access the tool. So, it is one of the simpler and easier attack tool.
