Cracking the Wired Equivalent Privacy (WEP) Key

Introduction:

The purpose of this project is to experiment with an IEEE 802.11 wireless network and learn how to exploit its security properties. In this project, you will learn how to use a variety of tools for surveying and sniffing wireless networks. The overall goal, however, is to crack the Wired Equivalent Protocol (WEP) protocol defined in the 802.11 standard. You have one month to complete this project. Don’t start your project at last minute. It does require some effort to complete!

The WEP protocol is crippled with numerous security flaws. Most of these
weaknesses are described in "Weaknesses in the Key Scheduling Algorithm of RC4" by
Scott Fluhrer, Itsik Mantin and Adi Shamir. The first person to implement this attack was
Adam Stubblefield.

Linux OS is highly recommended for this project, though Windows can do the same job as well. The best practice is to use a special security Linux distribution (such as WHAX, backtrack and etc) and a USB flash drive with at least 1G capacity. If you are not familiar with Linux, start your project as early as possible.

Hot spots and beyond

One particularly cool trend is the development of the Wi-Fi hot spots. If you’ve ever stepped foot in a Starbucks or Barnes & Noble (or one of several other retail locations who’ve gotten into wireless networking big-time), you’ve already been in a hot spot. Simply put (and we add in the details in Chapters 9 and 12), a hot spot is an area with publicly available high-speed Internet access via a Wi-Fi network.
Depending upon who’s counting and what exactly they are counting (somefolks only count “for-pay” or “official” hot spots), anywhere from tens to hundreds of thousands of hot spots exist in the U.S., and more worldwide.

Wi-Fi has become a common term that just about everyone knows, so too the term hot spot become a part of the zeitgeist. Hot spots can be found in some of the most unusual places. where you can surf the Web and the waves!)

Introduction to Aircrack-ng

When i write about this, i feel happy, you know why/ because with this tools i have been very success. now let learn this.

What is Aircrack-ng ?

Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools. In fact, Aircrack-ng is a set of tools for auditing wireless networks.

Aircrack-ng is the next generation of aircrack with lots of new features:

• Better documentation (wiki, manpages) and support (Forum, trac, IRC: #aircrack-ng on Freenode).
• More cards/drivers supported
• More OS and platforms supported
• New WEP attack: PTW
• WEP dictionnary attack
• Fragmentation attack
• Improved cracking speed
• Capture with multiple cards
• New tools: airtun-ng, packetforge-ng (improved arpforge), wesside-ng, easside-ng, airserv-ng, airolib-ng, airdriver-ng and airbase-ng
• Optimizations, other improvements and bug fixing

Hidden SSID,Ampuh kah?

Salah satu langkah pengamanan yang biasa banyak dilakukan para admin adalah mematikan fungsi dari SSID (non broadcast) tujuannya apalagi agar ssid tidak terbaca oleh para wardriver.

Nah yang jadi pertanyaan cukup efisienkah langkah tersebut? Jawabannya pasti TIDAK.

mematikan SSID biasanya hanya berdampak bagi pemula yang memakai wireless zero windows saja. karena WZC windows tidak mampu menngkap ssid yang terhide, namun sekarang aplikasi wifi monitoring seperti netstumbler sudah mampu menangkap, menganalisa serta mencapture SSID yang terhide sekalipun.

Meskipun demikian Memang ada benarnya juga agar langkah ini tetap dilakukan para admin jaringan disamping merubah default password serta rename kembali SSID dengan nama yang lain selain default pabrik.

Data Recovery For Laptop

A laptop has gradually assumed the role of a mobile office and a pocket diary that is a custodian of one’s personal and professional profile. Sometimes, due to a technical or mechanical mishap, the Laptop becomes the villain of one’s life by going dead and all of a sudden one feels as if one’s life line has been disconnected. Unfortunately, when the laptop goes dead and silent there’s a lot more that goes dead and quiet along with it. It is at such times that one can’t wait to bring it back to life and regain access to all the information stored in it. Every second that passes following a data loss means time and money. It is only after retrieval of data that one can resume one’s work and other activities since admittedly, these machines have become the focal point of one’s existence. Data recovery is the process of retrieving computer data that, for any number of reasons, has become inaccessible using normal methods. Data Recovery specialists help one quickly determine which data recovery approach is the best for one’s situation.

Fortunately, it is now possible to recover 99% of the data stored in a laptop all within the space of 24-48 hours. The Laptop being a much smaller machine compared to a regular PC, its Drives are very small in comparison to Desktop Drives and the internal mechanics too are miniature versions of their desktop counterparts. All the more reason then, that as soon as your laptop makes whining protesting sounds and throws up messages that spell trouble, it’s the right time to call in the experts, and Laptop Data Recovery experts specialists at that. A host of agencies now offers a complete solution for disk diagnostic, data recovery, and file repair needs.

History of Casino

The first official casino dates back to 2300 BC and goes to the credit of the Chinese. Playing cards were invented in France in and the first deck of playing cards was introduced by Johann Gutenberg.
The 17th and 18th century saw the first step towards casino style gaming clubs in England, Italy and Central Europe. The games played then was Hazard, faro, Macao Trente et quarante and Trente et un. Roulette came up only towards the second half of the 18th century. The most popular casino games in the early days was Baccarat, Craps, Hazard and Chuck Slack.
Online casinos can be basically divided into three groups-web based online casino, download based online casino and live based casino. In web based casino gaming, the gambler can play the casino without downloading whereas in download based casino, the gambler will have to download software to play the wager. But the game play is faster than web based other than the initial difficulty of downloading and installation. Live based casino is the latest concept in online gaming. The gamblers can play in an interactive and live environment. The best online casino games usually offered are Baccarat, Blackjack, Craps, Roulette, Slot Machines and Video Poker. Of these, the most famous games are Roulette and Video Poker. Apart from the smoke, drinks and noise, the experience of online gaming is in all other ways as exciting as the in-house casino gaming. And also, the online casinos give away cash as bonus. The gamblers are open to a wagon of information on online casinos and are free to choose their game and gaming house. Today, people from round the world play casinos either for free or for real cash.

Wi-fi packet sniffing on Ubuntu

Packet sniffers let you take a look at the network traffic of a wireless netwo
seeing what websites are people visiting, watch chat conversations, captur
unencrypted passwords, or just see how packets flow through different pro
This tutorial will show you how to discover wireless network and passively
(without interfering) sniff their traffic on Ubuntu (Edgy).

Drivers
Although many WLAN cards are supported by default in Ubuntu, some are not. Try downloading and installing the latest Orinoco or Prism2 drivers. Links are listed in the end of the text
Probably the easiest way to do this is installing a package called Wifi-radar. Wifi-radar will let you see the SSID, signal strenght, mode and type of the 802.11 standard (b, g, etc.) It doesn't provide much details, but for very basic use it's OK. Of course, there are tools that provide more details about wireles s networks.
Kismet is probably the most popular tool among wardrivers who use Linux. It sniffs traffic passively, maki ng it impossible to be detected and it even supports GPS. So go to http://packages.ubuntu.com and download Kismet from the networking
section. Install the package. Before you start, you'll have to modify the kismet.conf file.
Open /etc/kismet/kismet.conf with your favourite text editor and modify the source option to fit your needs. For example: source=orinoco,wlan0,kismet Now start Kismet from the terminal, using the sudo kismet command (root privileges).
