Step by step to crack wireless WEP encryption

For your information, WEP encryption is totally no safe at all! It can be crack within few minutes time with little effort only. WPA & WPA2 tend to have higher grade of security because you might need to match the sniff packet with the dictionary (database of all the password possibility). Perhaps, it is a 50GB text file or 100GB text file, who know? However, it seem like impossible to contains all the possibility of WPA & WPA2 password in a single text file.

So, I will demonstrate step by step on the WEP cracking process here. However, please ask permission from the owner first before doing anything silly on other people wireless network. Please take you own risk before you try the below step.

1. First of all get all the necessary tools for wireless crack. For me, I will use Backtrack 5 R3 as my based OS. Fyi, backtrack pre-loaded with all the software required by this lab. You can search for backtrack on google and download it before you start. I won't explain much on backtrack here. The software that need as follow,
  • airodump-ng
  • aireplay-ng
  • aircrack-ng
Backtrack 5 R3 (the latest version for now)


 2. You need to get a compatible wireless card or adapter to make this work. You may google "compatibility list of wireless adapter for aircrack". Then you will get the link. For here, I am using D-link 802.11b/g wireless adapter (DWA-110).

3. Launch the terminal in backtrack. Issue the command, iwconfig. If your wireless card detected then it will show you in the list. This is quite similar to windows ipconfig but this only show details for wireless interface in linux system.

Wireless interface detected as wlan0. So, the rest of work will use wlan0 as interface

4. Make sure you mode in Monitor mode. Most of the time the mode will in Managed mode. So, you need to change it as follow command.

To change from Managed mode to Monitor mode.

5. Start to scan the wireless network. Type :

airodump-ng wlan0

You will get the result as follow. Airodump-ng will help you to scan thru all the wireless network AP & host nearby your wireless card or adapter. You will see a list of SSID & wireless in the result.

There are 2 SSID and 1 client detected on the scan.
6. We going to crack password for SSID named FreeInternetAccess. There is a client connect to the SSID. Type the below command to collect wireless network packet.

airodump-ng --bssid 00:xx:xx:xx:21:30 -w /root/Desktop/test wlan0

--bssid, the SSID you going to collect wireless packet.
-w /root/Desktop/free, you going to write the file to desktop and name it to test as pre-fix.

The command to sniff and collect wireless packet to a single file.

The screen you will get after issue the command.

7. For you to crack the WEP key, you need to collect at least 25k packets data. Normal user traffic is slow for us to hit that number of packets. So, we try to generate some wireless traffic using aireplay-ng. Type :

aireplay-ng --arpreplay -b 00:xx:xx:xx:21:30 -h C0:xx:xx:xx:37:47 wlan0

During the traffic generation, you will get something like this.
8. Stop the packet collection (by press ctrl+c) once reach 25k of it.

Under the data show 25k of packets.
 9. Check your desktop. You will see few files already there because we save it to desktop.

The few files created from airodump-ng.
 10. Lastly use aircrack-ng to crack the .cap file. Please take note that the number of 01 will automatically add on to the original pre-fix of file name. For this case, the file name will be free-01.cap Type :

aircrack-ng free-01.cap

The key for this wireless SSID is C5:EE:B4:0F:A4

11. Done.

Please take note again, this tutorial is strictly for educational purpose only. Use it on your own risk. Anything welcome to leave your comment here.

Broga Hill

Finally, we managed to make our second trip to Broga Hill. This time, we go up to third peak which the signboard located (as you can see in the photo). We took a few photos there, and I think this is the best shot. Thanks to the photographer (by the way is T2H's brother. We didn't stay there for long because there are a lot of bees flying around and keep on "landing" at our body. Behind the signboard there is another small path which bring you to mountain called "Gunung Tuk Wan" but you need to walk some more 3.1 km for the peak of 675 meter. Today we made less stop compare to last trip. Hope next time can go up third peak directly without any "pit stop".

EOL of my passport

Time flies, my passport going to be EOL (End of Life) on end of this year. However normally we need to renew it 6 months before the expiry to maintain it's validness right? So, I going to renew it during May or June. Just heard recent few positive experiences from colleagues & friends, immigration department become very efficient on work and normally they manage to renew or issue new passport within few hours only. Sound nice & good compare to few years back which you need to stay there for the one whole day just to wait collect the passport when everything done.

Review back to my current passport, surprisingly there are really a lot of foreign country that I already visited. I didn't expected to visit those country when I got my passport. However, most of it is business trips sponsor by my current company Convergence Networks. So, thanks to all the bosses for being provide me such opportunity (even though some of its are actually working task for me but still I enjoyed it).

In total, I stepped in seven Asian countries (and only Asian). Countries in the list are Singapore, Thailand (Bangkok), Philippines (Manila), Macao, Hong Kong, Indonesia (Bali) & the latest China (Shanghai). For Singapore I been there for eight times, others only once.

Bangkok, Thailand

I been Bangkok on Jan 2011 for business training or more specific Extreme Networks Professional training. Yaw my colleague tag along with me for this trip. Actually we didn't have much time to enjoy as our mission is to pass ENS examination which to fulfill the distributor status of Extreme Networks for my company. We spent nearly one whole week @ Bangkok.

The really first impression for me @ Bangkok when I hang around is the messy cable management for their electrical wire. In Malaysia, hardly you can see the electrical wire hanging around on the street. In Bangkok, the cable is hanging around at the street in city center! Actually, the main issue is there are really a lot of cable hanging on the pole. If I treat the wire as my network diagram, perhaps this is the worst network diagram that I ever saw. For this, I would like to praise TNB Malaysia for their good job hiding the cable in the ground (even I think most probably the wire will messy in the ground as well).

When you walk along of Bangkok street, you will be seeing a lot of Japanese car instead of continental car. Honda & Toyota are two major brand that glance through your eye sight. I saw a lot of colourful taxi running around the city area. Wonder how my car look like in fancy pink, blue, yellow or red? Should be interesting right?

Colourful Altis running around Bangkok city ready to service

Besides LRT, Taxi, bus there is one more type of special public transport provide in Bangkok. Guess what? There are a lot of motorcyclist running around the city area and normally they will be waiting at hotspot area like LRT station & bus station to pick up their customer. This kind of public transport normally is for short distant only. I personally witness all the office lady (pretty & nice lo) get up the motorcycle directly without single conversation with the driver. In Malaysia, I cannot imagine what happen when OL get up to some stranger motorcycle. So, from this point of view Bangkok actually should be safer compare to KL.

Along the street there are a lot local people setup their food stall. On the way to training center, I saw many people bought their breakfast from the food stall. Personally I feel is not hygiene.

Luckily, I managed to pass my ENS written & labs test. This lab test quite challenging as the time given is very short. If not mistaken is two hour for four scenario based question. Accordingly to trainer Xie Rui from Shanghai, China, even CCIE candidate fail for this certification. However, as long as you pay attention during the class, there will be a lot of hints provided by Xie Rui.

ENS Classroom, nearly a week spent there

Last day of Bangkok trip, we went to China Town. Eventually, this is the place quite similar to our Petaling Street. The only different is China Town Bangkok is much bigger compare to Petaling Street, KL. Variety of wallets, bags, clothes, foods, for your choice. For those girls, I think you will excited to see that.

We are using "Do Do" car to ChinaTown 

Bags! 

And bags again 

ATM inside the market, interesting! 

Pearl... 

We tasted the burn banana, taste so so only

At same day, we are coming back to Malaysia. There are a lot of people in Bangkok airport. We spent nearly 1 hour plus to clear the custom. Then, we running all the way from custom to flying gates. Luckily, we are not left behind by airplane. Moral of story, make sure you clear the custom first and wait for your fly inside the waiting area to prevent any delay!

Bangkok airport is crowded!


Shanghai, China

Thanks John for this photo
Just two week ago, I been there for HP incentive trip. This is the most far place that I even travel. Thanks to GSLee for giving me this chance to travel there. The very first things I did was to check the weather when Lee offer me the trip. To my surprise, Shanghai still very cold even going to step into spring season. Average temperature is around 3-8 Celsius. Besides, raining season making the situation worst. I felt worry before I went there as I never been to place such cold. My dear prepare all the winter attire and group it nicely to my luggage (Thanks dear!).

Again, I flew to Shanghai by MAS instead of AirAsia. I enjoyed the salt peanuts again and I did bought back some pack for my dear. For those don't know what I say here perhaps you need to follow my old blog on Bali Trip. Before & during the fly I met some new friend (by the way I am the only person join the trip from my company).

When go Beijing you must climb Greatwall, when you come Shanghai you must try their 上海小龙包。As our Mr. tour guide Tony suggest, we went to a famous shop for our first light meal at Shanghai. When we reached the restaurant, there are a lot of people queue up for take away meals. We directly get to the third floor for in house dining. Tour guide assist us to order most of the famous flavor of the  上海小龙包。 There are original flavor, curry flavor, mushroom flavor & crab flavor. After tasting for few flavor, I insist the original flavor is the best. By the way, the curry flavor taste like maggi curry in Malaysia, lol.

 Closer look, I already took the soup

Be Extreme!

Extreme Networks Asia Pacific conference recently take place in Bali, Indonesia. I joined in the pass three days with my management (Bugh and Lee). First time to Bali (ops should I say first time to Indonesia? ^^), like here weather is hot & humid, quite few time we take shower but feel sticky on body as well.

Surprisingly, this time flying with Malaysia Airlines. Now only realize that all the while I was flying with budget Airline. So, seat is bigger, foods (I like the peanuts) and drink is unlimited supply, multimedia enjoyment, nice airport (LCCT like production factory), variety language newspaper supply and nice crew. Unfortunately, limited food choice on main course.

First day, after arriving we are given a warm welcome by a driver pre-arranged by organizer community. They assist on carry bags, luggage and offer us cold mineral water. Hotel just 20 minutes away from airport, which is the best hotel I stay ever (Sands Singapore is superb luxury but not as nice as this). By having a super king size room, I slept well for over three days. Later I will post some photos in room and hotel scenery. Stay tuned.

After having some local foods as our lunch in hotel, we had our very first opening event, CEO and others welcome us. Then was continue by a welcome seaside cocktails at night time. I did meet back some friends from Bangkok Extreme training. I did not really enjoy the foods but there are some nameplate maker providing free hand make wood nameplate for all the guests. Everyone were busy queuing up for that and did not even bother foods. Seem weird right?

Second day, conference continue with speech and presentation by Extreme Management staff from US (very often I saw them on youtube video, but this time just stood in front and talk to us). New product launching, APJ partner sharing winning experiences, are some activities throughout the days as well. We were served by an wonderful western food (out from hotel) at the end of days at night.

Third day, we break out down to region and had a direct 1:1 discussion with Extreme key person. I did asked some technical question but seem was not well response back (perhaps, my question is not clear enough). After that, we go for our team building activity. I went for water rafting. After going thru, I felt like this is not a dangerous activity if you follow the instruction from instructor. I would like to try out this in Malaysia soon. Heard Malaysia water rafting is more challenge, I am waiting for that. ^^ But so sad, I didn't bring over my own camera for that activity. So, just waiting photo from other. During the award night, my team managed to get first place, I did not even know it until the announcement is made.

Overall we had a fun trip. Hope to step into Bali again soon.
