WEP wireless security cracked in 60 seconds
If anyone is still using WEP for wireless security as opposed to WPA (or WPA2), be wary.
Codebreakers have discovered a way to crack a 104 bit key in under a minute. It takes a reasonably well specced PC around 3 seconds to process the accumulated data, and display the key.

Re: WEP wireless security cracked in 60 seconds
yeah, saw this on the real hustle
http://youtube.com/watch?v=pgBHjZUKW54 <-Home Wifi Scam
http://youtube.com/watch?v=ScEaD-SikrM <- Another Wifi Scam
http://youtube.com/watch?v=dltjEnrePxc <- Blue Snarfing
http://youtube.com/watch?v=6vcdt5GQVIw <- Key Logging Scam
It is pretty scary on what people will do. The Key logging is perticullay clever IMO... Log the keys, call them up and ask them to login to their online banking where they feel secure!
The wifi would scare me if they did that to me at my house, there again, i turn down the Router power so it only just works round the house.

Re: WEP wireless security cracked in 60 seconds
I'm still using WEP, what should I change it to...? I have a Linksys WRT54G router with DD-WRT firmware.
These are the options I get:
WPA Pre-Shared Key
WPA RADIUS
WPA2 Pre-Shared Key Only
WPA2 RADIUS Only
WPA2 Pre-Shared Key Mixed
WPA2 RADIUS Mixed
RADIUS
WEP
I'm using WEP at the moment so what should I do?

Re: WEP wireless security cracked in 60 seconds
Depends what your wireless NIC will support...
It should at least cope with WPA Pre-Shared Key

How do I find out what they support?
Which encryption method out of the list is the best?

Re: WEP wireless security cracked in 60 seconds
What make/model is your NIC?
I'm not a wifi security expert but I think WPA2-PSK is the best you'll get for home use.
The radius stuff uses some sort of server I believe...
[Edit] Have a read here...

Re: WEP wireless security cracked in 60 seconds
I have 3 laptops in the house...
The oldest one has a "Intel Pro/Wireless LAN 2100 3B Mini PCI Adaptor"
So what's the difference between WPA2 Pre-Shared Key Only and WPA2 Pre-Shared Key Mixed?

Re: WEP wireless security cracked in 60 seconds
I think mixed just refers to a mixed network, wireless & wired.
From what I can find, that NIC only supports WEP. Should be relatively cheap to get a PCMCIA card that supports WPA though...

Re: WEP wireless security cracked in 60 seconds
It's possible, the spec I found just said hardware support for WEP.
What make/model is the laptop?

Re: WEP wireless security cracked in 60 seconds
Have a read here also.

I use WPA personel with AES as my Xbox 360 wireless adaptor doesn't support WPA2.

Re: WEP wireless security cracked in 60 seconds
The laptop that has the "Intel Pro/Wireless....." is a IBM Thinkpad T41 and I ran the ThinkVantage System Update but it didn't come up with any updates...
I checked on the Intel website too and I have the latest drivers...
How do I find out what software version I have?
http://support.intel.com/support/not.../cs-006109.htm
What's the difference between AES and TKIP?

Re: WEP wireless security cracked in 60 seconds
AES was designed for WPA2 but can be used with WPA if the router/adapter support it. If they do, you'll get given the option. If you can use it, it is more secure than TKIP.
You can find out the driver software version through device manager.
Right click on the NIC & choose properties. Go to the driver tab & the version number will be on there...

Re: WEP wireless security cracked in 60 seconds
OK so I have driver version 1.2.4.41 but it's not on this list so I'm guessing I can only use WEP?
