Wifi WEP is Hacked in “less than 60 seconds”

wifi WEP hacker

In less than two minutes hackers can defeat the security measures protecting many home wireless internet connections.

Defeating these measures could let them capture passwords, steal confidential information or download illegal pornographic material using the connection.

Many home internet users rely on an encryption system called Wireless Equivalent Protection (WEP) to stop others using their wi-fi link, even though WEP has long been known to be flawed.

In early April three cryptographic researchers at the Darmstadt Technical University in Germany revealed a method of exploiting the flaws far more effectively.

Before now it took at least 20 minutes of monitoring the airwaves before it was possible to break in to a wireless network protected by WEP.

Now, armed with a program iwritten by the researchers, it is possible to break in to the same network far faster.

"Breaking in to a WEP protected network is now very easy to do," said Erik Tews, one of the researchers.

"Doing it in 60 seconds is realistic, or five minutes in the very worst case. We think now that WEP is really dead and we recommend that no-one should use it."

In its place he recommends an encryption system called Wi-fi Protected Access (WPA), introduced four years ago to replace WEP. "We have had a very close look at WPA and we can’t find anything to exploit," he said.

The only known way to defeat WPA encryption – and WPA2, a newer version – is to use what is known as a brute force dictionary attack.

This involves trying millions of different words or combinations of words from in the hope of stumbling upon the correct password.

Dell Set to Sell Ubuntu Linux

Ubuntu on DellLinux has never been a consumer option on mainstream hardware from a name brand manufacturer. Until now.

Dell and Canonical today are announcing that Dell will ship PCs with Ubuntu Linux pre-loaded. The move follows an unprecedented outcry from Dell’s users who demanded that Dell support Linux for consumers and specifically Ubuntu Linux.

"We’re obviously very excited about this. It’s a strong endorsement of Ubuntu and is recognition for the traction and momentum that we’ve been building over the last few years," Jane Silber, director of operations at Canonical, told internetnews.com. "As well it is a true broadening off access and adoption for Linux in general and Ubuntu in particular on the desktop."

Though Linux has been available as an option for servers and business workstations from Dell and other hardware vendors before, consumer-targeted desktop PCs have never had this type of offering.

Initially the Dell Ubuntu pre-load option will be available only to U.S. consumers purchasing through Dell’s Web site. Dell engineers will be installing the recently launched Ubuntu 7.04 Feisty Fawn.

Dell will install the version of Ubuntu that is identical to that which is freely available and not some special version made just for Dell, according to Silber.

Canonical also noted that any demand that the Dell deal may drive toward Ubuntu will not be a problem. Ubuntu updates on a fairly regular basis, with users connecting to the Ubuntu update infrastructure to download patches and updates. In the case of the recent Feisty update, Ubuntu servers were overtaxed with users waiting many hours to download the full update.

"There is a big difference between providing updates, which are generally small, and having people waiting to download 700MB ISO images, which was the release-day issue," Silber explained. "We have a very healthy mirror system already; we have over 100 mirrors around the world and I don’t expect any problems."

Dell will not be offering the KDE Linux desktop variant of Ubuntu, called Kubuntu initially, and will focus only the GNOME Ubuntu version. That said Silber was quick to point out that this is just the beginning.

"We’ll see how it goes, as both companies are interested in serving a market that exists and, clearly right now, it looks like there is a pent-up demand for Ubuntu, and that’s what we’ll be delivering initially," Silber said.

Dell had been soliciting customer feedback since February through its IdeaStorm Web site about what people wanted. Pre-loading Linux became the first customer-requested option adopted by the company, with Ubuntu being the specific Linux version that users were asking for.

Though Silber declined to comment on the revenue arrangement surrounding the deal with Dell, she was quick to note that, as always, Ubuntu will remain free. She explained that Canonical’s business model is around support, certification and training. "With Ubuntu on Dell, commercial support is available for those that want it," Silber said. "For those that opt not to purchase, there is always community support."

Though the deal with Dell marks a significant milestone for Ubuntu and for Linux, Silber noted there are still some challenges.

"We will need to see the demand for the support offering; it’s unknown at this point," Silber said. "There is proven demand for pre-installed Linux this has been a well researched business decision to do this."

Silber added that she expects the Dell rollout to go smoothly but she’s been around long enough to know that there are always surprises.

Beyond Dell, Ubuntu already has a hardware certification deal with Sun. And Silber expects that with the Dell deal in check, Canonical will continue to expand its market share.

"The continued strengthening of the ecosystem both in terms of skills and education and in terms making Ubuntu available and accessible through this major distribution channel will continue the march toward much, much broader adoption of Ubuntu," Silber said.

Making Sure You Are Beautiful

A lot of times web designers, or even people who paid money to get a web design, wonder: "Does my website look good? Does my website look good on Firefox, but does not on Internet Explorer? Other way around? Does my web site look good on Firefox, Internet Explorer, but not on Safari? Does my web site loo…. etc."

Here is a wonderful tool – browsershots – that checks any website against multiple (and here multiple means a lot of) browsers and their versions, and returns screenshots of this website exactly as it appears in those browsers.

Here is a choice of browsers that ‘browsershots’ uses to test a website:

Browsershots Browsers' choice

After a website is entered for testing, it takes up to 30 minutes to get all the screenshots, but this time is definitely worth it, since the creator/owner of the website is sure that "Yes – I am Definitely Beautiful!"

Firefox Rise – IExplorer Dies

According to xitimonitor Firefox is getting 25% share in Europe. That is a huge deal – now every 4th European uses Firefox to browse the www. Here is a chart that shows European Firefox usage per country:

 Firefox Europe Usage

 
    Besides Europe, Firefox wheels spin all over the World, for example in US over 15% of users use Firefox, for Australia it is 25%, almost 12% in South America, over 13% in Africa and around 12% in Asia. Here is a snapshot:
 
Firefox World Usage
 

    There are three more factors that play in favor to Firefox:

  • Everybody wants MAC :)
  • Ubuntu is getting very popular
  • Vista is not exactly going anywhere, while XP is going, but mostly going down

    For somebody who does not do any web development and uses Microsoft Windows products (XP, Vista – well who uses Vista anyway.. ), this may not sound like great news, but for everybody else it is a pleasant "turn around", and it is going towards:

  • Much better browsing experience for people with MAC, Linux, and other non-M$ OSs
  • No more optimizing for IE, including those ugly JavaScript if(IE)/switch(OS) statements, and different CSS

    Yes, the idea is that Internet Explorer will die out the same way it was born – along with Windows
    It will not happen overnight or tomorrow, but it is already happening today…
