do these people shop?well a WLAN card is probably that cheap now..
I believe Marshy is our resident expert on this... something about external antennae and a pringles can..
Surprised that No10 are susceptible to such an attack though.. it's not bloody difficult to enable WEP and this 'expolit' has been known for as long as I've had WLAN kit at home (12 months just)..
Muppets..
It'd be interesting to see what's in Tony's favourites though.. probably www.xxx-pregnant-pentagenarians.com

FFS, that is NOT what warchalking is about! It's a simple set of symbols you can chalk up on the wall or pavement, to inform others that there is a wireless LAN nearby and how to connect to it and it's usually put up by the LAN owner.
Of course, the network being used should be secure in the first place, anyone who sets up a wireless link without appropriate security is asking for trouble. Sniffers can be used to detect and log into the LAN even if there is no warchalk marking on the street.

That's the kind of report that you get when journalists comment on things they don't understand ... sounds a bit like "speed kills" reports doesn't it.
Yes if you set up a wireless network you may be able to access it across the street - it's available in a circle around the access point (just like a radio antenna - gee I wonder if that's what the Wi in WiFi means - wireless). If you don't want people to access anything with it then you turn on the encryption (which may not be done which may be a security breach but it's nothing to do with "warchalking").
This I believe,is how Starbucks is putting WiFi into some of their coffee stores, turn up with a laptop and a WiFi card and browse the net over your coffee.
I believe that you can have your WiFi network un-encrypted, so that others can share your broadband connection, but that in itself does not constitute a security breach on your computer. This is the real idea behind warchalking - just some people being generous (foolish?) with the spare capacity on their internet connection.

Warchalking is more like the marking up of where the WLANs are rather than the owners of said wireless networks allowing it. It's because radio leaks outside company premises and because companies are cr*p at securing them, warchalkers are simply showing others where access may be had for free...
I used to work in IT recruitment and Phil Cracknell was one of my candidates. He is a very good IT Security Guy and used to work for Zergo, now Baltimore Securities, then he was head of IT security at Nomura before moving on to Scient in the late '90s. I think he then set up his own security company as the market was crap and he was well up in the 6 figure salary category - and the first figure wasn't a 1.
Basically, he's the dogs b0ll0cks.

Hmmm, Thank god you aren't it recruitment anymore, I wouldn't want you as my Agent!

Sorry richard, do you know me?
It's good to see we're all friends here.

Would like to think so, it was only MY personal opinion.

That's exactly what warchalking is all about - if you find a good bit of unsecured broadband internet access somewhere, mark it up so others can benefit! Best done in chalk, so next time it rains somebody has to check that said access is still there and re-mark it.
A good friend of mine who used to work in the City was moaning to me only last weekend that whenever he fires up his network connection on his WiFi laptop, he usually gets a choice of several networks to join & has to scroll to find the one he actually wants!
Seems to be a lot of unsecured networks out there...

Hmmm... Looks like NetworkWeekly are having network problems. Fills you with joy, doesn't it?

Without reading any of the transmissions, I wonder how our intrepid friends deduced that there was anything sensitive being broadcast? Anyone who has ever worked with the civil service will know that they are acutely paranoid about "official secrets". Sensitive data doesn't go anywhere near unsecure boxes. They use seperate LANs, private telecomm links. It cripples efficiency coz non-classified data goes from normal desktop boxes with internet conectivity and Jo Schmoe's normal e-mail account, but anything vaguely sensitive (like bog roll budget for 1983) goes from the PC in the corner of the room that is covered in padlocks.
I wonder if they meant "packets" when they said data "parcels".

Dead easy to make, Roop has made a few, the last using an empty nescafe coffee tin, the type you get at work. And it actually works.
The Australians have taken it a step further and are "warflying" ie taking the equipment up in a plane and flying round the skyscrapers to find the unsecured networks.
Ahhh so thats why Roop wants his PPL.
I have great fun warwalking/chalking/driving/peddling. Just to see what's out there. Not after connectivity as I have all the bandwidth I need at home on ADSL. Forget Pringles can antennas, I have a waaay better design that'll give you shed loads more gain, but it's pretty directional. I've managed to easily boost the range of my WLAN card by 600% using a bean can. Simple antenna building / RF propogation stuff really.
Planning on a monster gain waveguide antenna built with a four foot length of drainpipe. Also, I have a spare satellite dish hanging about. Can easy get 10km + point to point links with these without any boosting from the cards (they're only 100mW). Can cook yourself at 2.4GHz though so need to be a little creful of over-exposure to RF...!
There's 4 wireless AP's on my small estate alone here in Tewkesbury, not including my own (which is WEP'd, although admittedly crackable if you've got a Linux box and shedloads of time to monitor my traffic).
Just need a mag-mount antenna for my car now
Oh, and an iPaq to strap on my bike

They drove throught the square mile and picked up all sorts of info including unencrypted passwords, sensitive bank info etc..
WLANs are only as secure as the people's ability to set up and configure them correctly. I don't think WLAN's are particularly secure whilst reliant on user level security. Too many sniffed up bankers in winebars wittering on about amazingly clever their passwords are.
