How secure is your WEP key?

How secure is your WEP key?
At this point I find it amazing the amount of unsecured wireless networks out there. It is totally frustrating as there are not only leaving his home network open or worse, Internet service providers offer routers with keys laughably weak. Am I the only one who thinks that WEP should be buried under three meters of land?
That is why we propose to test our network. In our experiment we decided to put a router with a WIFI network protected by a 128bit WEP key alphanumeric. Our idea is to be our own attackers. For this we need:

1. PC Laptop: Compaq Presario CQ50-100ES

2. Linux : Ubuntu Lucid 10.04 (although WifiWay is a good choice)

3. Wifi Adapter powerful: AWUS036H ALFA USB

We can use the card wifi bringing our laptop. It may happen that you have a Broadcom chipset card or your Atheros this incompatibility that prevents you from working a hundred percent. Also, you want to use an external adapter that enables use higher gain antennas to using your laptop.

The reason I decided on the ALFA AWUS036H to be an adapter with one watt of power, has an interchangeable antenna 7dBi gain and we can change for any other antenna compatible with the RP-SMA connector. The Alfa ALFA AWUS036H has a Realtek RTL8187L chipset that is compatible with almost any distribution. I think we have more economic models with chipset RT3070 Can be found for about 20 euros in shops, with shipping included for free from Microcubo.com Spain.

Before we go on the hunt for our own network, we have to install aircrack as a basic tool. I would add john the ripper and weplab, but not necessary for this occasion.

Sudo apt-get install aircrack-ng

Armed with all this and the battery charged I went to the plaza in front of my house. I turn on my laptop, I start my session and everything connected run the terminal .

Step 1: List our interfaces wireless

The command iwconfig to show us information about available adapters. In my case it appears like this:

misha @ twiki: ~ $ iwconfig

I no wireless extensions.

eth0 no wireless extensions.

wlan0 IEEE 802.11bg ESSID: XXXX

wlan0 is our wireless network card. This may change, it may be ath0, wlan0, wlan1, etc …

Step 2: Put our card in monitor mode:

sudo airmon-ng start wlan0

This will create the mon0 to be working from now.

 

Step 3: Start capturing packets.

Sudo airodump-ng – ivs-w 11-c data mon0

This game with little advantage.

- Ivs indicates that we want to capture only ivs (initialization vector, a block of bits that is required to allow a stream cipher or block cipher in a cipher modes, with a result independent of other figures produced by the same key). If we define all traffic is captured.

-W indicates the name of the file to save the information.

-C define the radio channel by which we are listening. If we define capture all the traffic network in all possible channels.

Broadcom
Start the party. Here’s to have a little patience, we need a lot of valid ivs to start hacking your network. But there are little tricks to expedite it. Injecting packets.

Note: Do not close the terminal tab, or open other new instances. Throughout this process should be running.

Step 4: Adding salsa to the mix:

sudo aireplay-ng -1 10-e My RED-AP-h MAC MAC ATTACKING mon0

This command makes a false authentication. An attempt to associate to the network in order to generate large amounts of extra traffic in the future.

e is the MAC from our BSSID (our router)

h is the MAC of your PC

The MAC (English acronym for media access control, in Spanish “media access control”) is a 48-bit identifier (3 blocks hexadecimal) corresponds uniquely to a card or device network. Also known as physical address, and is unique for each device. This can change it using false macs, but the goal of this guide is that we can assess both the WEP key is safe today.

If you do not know what your MAC, you can omit this value even if the ifconfig command can also help;)

sudo aireplay-ng -3-b MAC-h AP MAC-x 600 mon0 ATTACKING

With this line, we define that inject traffic obtained from the previous step above a rate of 600 packets per second. Imagine the number of valid packets that are going to get.

If all goes well, soon began to rise the number of packets and begin to decipher your own key. It is recommended from 500,000 packets but the more the better. You can start long before the hack to achieve this figure, although our chances of success are lower.

Step 5: Crack your own code:

sudo aircrack-ng – 128 0-n-01.ivs data

Where-n defines the robustness of our key, in our case 128 bits. The other option is -64 bits, hopefully not for you.

If all goes well, in a few minutes (can be longer) you have your wifi key on your screen. Did you find it easy? In the market there is a device called Wifi Robin does all this and more automatic. It costs about 66 euros, battery, leave it at the window and within minutes is the key to your network. Given all this …. You really do not want to change your network password for something at least WPA-PSK?

 

I insist that this is not a hack to use guide. We have not gotten into complicated issues or talk to break the neighbor’s network. This is to see how easy it is to break the WEP key that our ISP is determined to get by default. In my case it was needed 15 minutes to lose the innocence.

Calligra Suite platform office suite, free and open source KDE project

Calligra Suite (created from KOffice) is a multiplatform office suite, free and open source KDE project, but is independent of this

Calligra Suite (created from KOffice) is a multiplatform office suite, free and open source KDE project, but is independent of it.

Calligra Suite uses the open document format standard OASIS OpenDocument natively. It also includes import filters to work with some file formats other office suites.

Suite Calligra partially takes into account internationalization documents use the Unicode encoding and allows you to write texts in languages ​​written from right to left (Arabic or Hebrew), though not yet in languages ​​written from top to bottom.

To automate Calligra Suite allows programming of D-BUS scripts in various programming languages ​​like Python, Ruby and JavaScript.

Calligra Suite was originally designed to run on Unix-like operating systems, but since version 2.0 is possible to execute Calligra Suite on Mac OS X as well as Windows .

It is a processor free word, for the KDE desktop environment, able to handle style sheets and frames.

 

Calligra Words.

Despite the name, Words is not just a clone of Microsoft Word, in some important respects different from it. The scheme of the arrangement of texts is based in frames, similar to Adobe FrameMaker.

These frames can be located anywhere on the page, and can incorporate text, graphics and embedded objects. The differences with respect to OpenOffice.org are several, among them that requires fewer resources and greater integration with KDE.

KWord was created as part of the KOffice project in 1998, using different ideas of FrameMaker, as the approach to the frames. In 2000, KWord became a state in which it was very difficult to fix the problems and no one was working in the known issues.

There was no release of an official in that time. The same year, a new maintainer started working on the application, working throughout 2000 and early 2001 to correct the structural problems of the application.

Many desktop publishing applications using frameworks such as KWord does, but these applications use a concept called ‘Master Pages’ that allow the user to design the structure of the document.

Unfortunately, this concept has a tremendous toll on usability, while most users do not understand the latent concept behind the master pages.

The developers of KWord frames designed to be a usable version of the master pages, with a clever copy of the frames and their position when they are created, for example, when there is too much text for a page.

 

Calligra Tables.

Tables (KSpread above) is a free editor spreadsheet, supports multiple sheets per document, templates, series and more than 100 mathematical formulas.

The functions of KSpread are the multi-sheet for document formatting qualified, support for over 100 built-in functions, templates, graphics, spell check, hyperlinks, support series, conditional coloring sets, scripting and data classification.

KSpread is capable of importing different formats using filters spreadsheets, including Microsoft Excel, Applix Spreadsheet, Quattro Pro, CSV and OpenOffice.org Calc

 

Calligra Stage.

Calligra Stage (above KPresenter ) is a free presentation software, allows you to insert images and effects.

The native file format is the format for KPresenter OpenDocument presentations, whose extension is. Odp.

In addition KPresenter is able to work with Microsoft Powerpoint presentations, Magicpoint and OpenOffice.org Impress.

 

Krita.

It’s a free program for manipulating and editing raster graphics, focused on the issue of digital paintings, unlike Adobe Photoshop or GIMP, that specialize in photo editing.

Formerly the name was then Krayon KImageShop, but legal problems should change the name Krita.

The name “Krita” comes from the Swedish word for crayon.

On the other hand, “Rita” in Swedish means drawing.

 

Karbon .

Is a vector graphics editor with a user interface easy to use and highly customizable.

This program is the same use as CorelDRAW, Adobe Illustrator, Freehand and Macromedia Freehand.

Formerly the name was Kontour, then KIllustrator.

Karbon14 name comes from a play on words between KDE and the radioactive isotope carbon-14.

 

Calligra Plan.

Ex-KPlato, is an application for managing multiple projects with moderately large resources.

Is able to generate Gantt charts to show the timing of tasks, task dependencies can be used, use work breakdown structures in a tree, etc..

Fa progetto part of Calligra Suite (above KOffice ), a software suite di di produttività originally personale per il desktop environment progettata KDE porting divenuta sulle multipiattaforma Librerie grazie to Qt4.

 

Kexi.

It is an integrated development environment for managing databases.

Allows you to design and implement databases, insert and process data and make queries on them. Kexi can connect to different database servers such as PostgreSQL and MySQL.

You can also work without a server engine using the embedded SQLite database, which allows users to store data and the design of the database in one computer file. Forms can be created to provide an interface to the user as to work with the data.

With Kexi can query data in graphical form, print or preview reports, schedule scripts with Python and Ruby languages, and has a macro language similar to Microsoft Access. All database objects (tables, queries, forms, etc..) Are stored in the database, providing full application sharing, data and design as a single ordinary file.

Kexi tries to occupy a place between spreadsheets and complete solutions for databases that require a more elaborate design. The idea of ​​this development appeared due to the lack of applications that have the features of Microsoft Access, FoxPro, or FileMaker, but they were free, powerful, open standards and were using portable to other operating systems and / or hardware.

KOffice 2 is planned in merging Kugar, a generator of business quality reports Kexi.6

 

Calligra Flow.

Calligra Flow (Kivio above) and an semplice programma per Disegnare diagrammi, organigrammi, and diagrammi di fluss delle Applicazioni, integrate applicativi nei vari progetto della Calligra Suite suite (KOffice above), a software suite di di produttività per il personale originally progettata KDE desktop environment, divenuta sulle multipiattaforma Librerie grazie to Qt4 porting.

È software release, the cui è stabile latest version 1.6.3 of 7 june 2007. Faceva della part of the KOffice 2.0.0 Pacchetto. nel rilasciata Maggio 2009, an office suite to the desktop environment KDE Integrata.

I Lavori his iniziati sono nel Kivio 2004.

The first version was part rilasciata 2004 nell’Aprile di KOffice 1.5. Il team di Kivio Volontari fencing sta per per il soon render it agli altri assieme componenti rilascio della suite, più impegnativi. Turner disponibile dalla versione 2.4, eat dal risulta ufficiale site.

Braindump Calligra.

It is a tool for representing graphs and diagrams.

You can run independently or used to create graphics for KWord, KSpread, etc..

The application is relatively simple compared to other office applications such as OpenOffice.org, designed for small data sets, and using only the most common types of charts (histograms, pie charts, line charts, etc.)..

SEO, or the danger of one-way optimization

Questions. I wonder. I go and come back for a while the emotional side of my troubled head rational crazy. And I get for questioning, reflecting on everything I see, read, listen, I believe, understand, I feel as if my life depended it: What is the use internet?

Of course this is not a question that I lose sleep or set the course of my life, but since this is a blog about technology and education, I think I used to use this space to think and attempting a sketch of an answer to that question.

In any case, as to start running a little more coherently the train of thought, the specific question would be ‘What is the use today internet? ‘ . What’s more, ‘What will the Internet in the future ? ‘

Sorry to be somewhat pessimistic, but I firmly believe we are headed for ruin everything again.

The trigger for the decline in trading today my faith in the technological developments of mankind has to do with a short note in Microserfs , about Inframutt , or what they themselves call “the Google vice versa ‘

This is such a crazy project that swarm over the network, but never pulled any marks left by the strange or, as in this case, particularly the idea which was conceived. To quote the article’s author,

This does not even work, but the concept is intriguing. Some time ago someone thought it would be quite an idea to create a Google vice versa, the less relevant the pages were the first. This will also avoid all basurilla “artificially placed by positioning” messing certain searches. And so was born Inframutt, who apparently stayed in alpha and was never heard.

The idea of artificially placed trash positioning , which in some cases we may attach perfectly to the definition of SEO ( Search Engine Optimization , Search Engine Optimizer and SEO ), I immediately recalled a presentation by Eli Pariser , director of MoveOn , in a conference TED . Pariser spoke there, briefly, about how the segmentation of the information for the user , based on their usage habits of the network, complete isolation from the global to allow you to receive only what you can-you- should know.

More on
Tim Berners-Lee
Google
The equation is simple: if by SEO select us what someone decides that we like to see / buy, and the search engines determine what we read / know how to find what is really valid, which help us to be anything but buy-things, data, lies and even revolutions or wars, ‘the network to find what was its essence, its rationale, that is, the sum of all human knowledge?

One of the milestones in the history of the Internet has to do with the companies began to see the 90 the mother lode of online advertising . Before Windows , before Tim Berners-Lee and the Web, before the search engines and above all, the BBS does not pay : it is known that 999 words or more is not worth what a picture, so I could write much without a banner or annoying spam bother pretending to sell something sight. It was not worth getting into where you could display.

That internet-or rather, its predecessor Arpanet – the boring, black and green or amber screens boring nor paid – in a few years wove the fabric of a network that developed much of the best and most lucid in communication the history of mankind.

All that now supports tissue, mostly, spam, pornography, targeted advertising, analysis of information obtained, to use a soft-term without our permission, imposed ideologies, networks and other harmless delights of our distraction, for the sole purpose of telling us what to think , to buy, what to believe, who want and who to hate.

This is a one-way optimization: optimizes the way to get you to purchase but no real experience and successful navigation for their own interest and benefit.

I do not like the internet. I do not like wasting time looking for what I want because I have to scavenge someone decides that I need. I do not like when I speak of optimization to sell more, as if the only reason why there is this way.

I began this post promising a sketch of an answer to that question of ‘to serve the Internet?’. But it is clear that for the moment, there is no answer.

Or maybe it is in our hands but we do not know what to do with it.
