Researchers crack WPA encryption

Pair break code used on half of all wireless traffic.
Two researchers have apparently cracked a part of the Wi-Fi Protected Access (WPA) encryption protocol.

Erik Tews and Martin Beck claim to have broken the Temporal Key Integrity Protocol in under 15 minutes. The breakthrough means that data sent from the router to the PC can be scanned, but not the other way around.

Access to this traffic could also enable a hacker to send false information to a client on the network.

The researchers developed a way to get the router to send out large volumes of traffic, thereby giving them a large data set to work with, in order to break the key using a mathematical formula the pair developed.

WPA's predecessor, Wired Equivalent Privacy (WEP), which was developed as one of the first wireless security systems in the 1990s, is now considered almost completely unsecure as it can be hacked in just a few minutes using tools easily available on the internet.

WPA2, an advanced version of the protocol, is not susceptible to the new attack and is still considered secure.

But WPA2 is a relatively new platform and was only made mandatory in all new products from March this year, meaning that many users may have routers that do not support the standard.

Experts believe that this latest development could open the door for a host of new wireless network attacks, forcing many businesses to upgrade their systems to remain protected.

Full details about the WPA hack will be revealed and discussed next week at the PacSec Applied Security Conference in Tokyo.

WPA2 is, apparently. Just don't broadcast your ESSID and you'll be a lot safer.

What and not be "cool"!!!:shock:

A check into the bowels of your wireless router will tell you what IP's are sucking down your sacred bandwidth, or you could just look out the window to check out any "strangers" lurking in vehicles staring intently at their screen while they download illegal stuff, or not.
Or am I just being paranoid???:shock: :shock: :shock:

no wirelss isnt cool. interfernce lag (if your a gamr of course). not just the privacy issues here but ur right mal it doesnt take much to watch and see whos potentially getting into your wireless. i like wireless for the convinience but sometimes but well...just not my option if i can help it.

Beyond the issue of the theft of bandwidth, the compromising of one's wireless security is really not that big of a deal as far as looking at my stuff is concerned.
The only issue I have and it is not a proven thing, is the hyjacking of my IP to use as a shield for not so nice activities.
There have been several cases where child porn sites were being accessed through a compromised IP connection and the real ownwer of the IP had not a clue until the Law came aknocking.
Of course, if you have nothing on your hard drive that is incriminating, you don't have a problem, except for all the hassle involved in the ensuing process.Meanwhile, the real offender has driven out of the area if they are mobile, or shut down their puter and are invisible.

That, for me is the real "worry" about compromised wireless connections.

I've set up my wireless router to not broadcast the network name, use WPA2 with a nice long pass phrase and only talk to mac addresses that I tell it it can.
And yet8-[

Yep, it's all still open ended, still a bit scary. A bit like waiting for the "Sword of Damacles" to fall.8-[

another bout of procrastination has gripped me again so i decided i would plug in my wireless USB thingo just to see what was out and about in my street. picked up mine and the neighbours wireless so i attempted to connect to hers and found the password was indeed left blank :o
but it wasnt happy with my IP address so i manually configured it to suit. could get in no problems even bridge the connections. next time i see her ill let her know, maybe offer to configure a safer option. was WPA. iv changed mine to WPA2 now.

**Please note this was purely for research i didnt use her internet at all or use it maliciously i have my own connection for that:P **
