security wireless network: Appendix A. Decibel

LINUX DISTRIBUTIONS

The most known is backtrack versions(3 and 4) i will use backtrack4 another distributions wifiaway,wifislax.,everyone of them its specialase in auditoria of wireless network with a lot of programas like: airodump-wireles network scanner aircrack-its use to crack wep pass wireshark-internet traffic escanner It is a simple 3 examples of 3 programs from linux distributions you ask me how did this work how a hacker can use this to penetrate my wireless network: first one we need to download backtrack4http://www.backtrack-linux.org/ this is the link were you can download any backtrack you wish,try with live cd you can install backtrack into your sistem using a virual machine like VMWARE http://www.vmware.com/ this is the oficial site of vmware you need to download wmware workstation 7 you can use 30 days this program afree if you will subscrib (its free)i will put a video on youtube about how to run backtrack4 in vmware its very simple to do this. The youtube movie its show you how can a hacker crack a wireless network(wep key). The second video its about how can you run backtrack4 in vmware its very simple

SNIFFING PROGRAMS

Once penetrade the network the hacker can use snnifing programs such as cain&abel, wireshark,to see the internet trafic into the network with the final goal to steal your passwords. For now i will present only this two programs: cain&abel-its a complex program how has a sniffing tool and a crack tool. The basic idea in the traffic interceptation is that the attacker is interposed between the router and pc atacked so that traffic passes to the attacker pc first and then go to the router,this is the basic idea.i will put an video on this program,one more thing-i use this program under windows. wireshark-its almoust the same tipe that the first one but in this you will need to process a huge cantitate of data.This one its cames with backtrack4 but also can you use under windows.

WHAT CAN WE DO?

As you can see the tools hackers are diverse and complex as I illustrated above and is only a small part of the multitude of ways that we can be attacked, I think we should show more interest in everything around us and especially to new Wireless technology is the future because I believe that the transmission and receipt of data. How can we defend against these attacks, I have some advice: -If you have a wireless router and its has an wep key to have acces change it into an wpa key(choose a key that is not into the dictionary -phone number f.g) -check if at yor network are conected other pc that you know it If you connect through a public Internet network try to keep on mind that someone can spy on you and he can see what password that you type so dont type important psswords(such paypal pass)

attack methods

ACCESS POINT CLONE (Evil Twin) Traffic Interception – An attacker fools legitimate wireless clients into connecting to the attacker’s own network by placing an unauthorized access point with a stronger signal in close proximity to wireless clients. Users attempt to log into the substitute servers and unknowingly give away passwords and similar sensitive data. JAMMING- Denial of service attacks are also easily applied to wireless networks, where legitimate traffic can not reach clients or the access point because illegitimate traffic overwhelms the frequencies. An attacker with the proper equipment and tools can easily flood the 2.4 GHz frequency, corrupting the signal until the wireless network ceases to function. In addition, cordless phones, baby monitors and other devices that operate on the 2.4 GHz band can disrupt a wireless network using this frequency. These denials of service can originate from outside the work area serviced by the access point, or can inadvertently arrive from other 802.11b devices installed in other work areas that degrade the overall sign. CLIENT-CLIENT ATTACKS Two wireless clients can talk directly to each other, bypassing the access point. Users therefore need to defend clients not just against an external threat but also against each other. File Sharing and Other TCP/IP Service Attacks – Wireless clients running TCP/IP services such as a Web server or file sharing are open to the same exploits and misconfigurations as any user on a wired network. DOS (DENIAL OF SEVICE) – A wireless device floods other wireless client with bogus packets, creating a denial of service attack. In addition, duplicate IP or MAC addresses, both intentional and accidental, can cause disruption on the network. Brute Force Attacks Against Access Point Passwords Most access points use a single key or password that is shared with all connecting wireless clients. Brute force dictionary attacks attempt to compromise this key by methodically testing every possible password. The intruder gains access to the access point once the password is guessed. In addition, passwords can be compromised through less aggressive means. A compromised client can expose the access point. Not changing the keys on a frequent basis or when employees leave the organization also opens the access point to attack. Managing a large number of access points and clients only complicates this issue, encouraging lax security practices. ATTACKS AGAINST ENCRYPTACION 802.11b standard uses an encryption system called WEP (Wired Equivalent Privacy). MISCONFIGURATION Many access points ship in an unsecured configuration in order to emphasize ease of use and rapid deployment. Unless administrators understand wireless security risks and properly configure each unit prior to deployment, these access points will remain at a high risk for attack or misuse
