WPA networks cracked in just under a minute, researchers claim

by Ross Miller posted Aug 27th 2009 at 9:42PM

To think it was just a few months ago that we thought taking 15 minutes to crack WPA encryption was a feat. Researchers from Kobe University in Japan are claiming they can best that by a wide margin by cracking any WPA-protected connection using the TKIP algorithm within just one minute flat. The details will be revealed at a tech conference on September 25th. Feeling paranoid? Bump up your encryption to the still-secure AES algorithm or WPA2... and if you're just wanting to live life on the edge, consider downgrading to WEP -- it's as good as open at this point anyway.

WPA cracked in 15 minutes or less, or your next router's free

They always knew it could be done; that a hacker with enough time and processing power could watch your WPA-protected wireless network and, eventually, decrypt your precious datas. In under 15 minutes, though? "Inconceivable!" those hypothetical security experts would say -- but they're about to get a lesson from WiFi wizard Erik Tews. He'll be giving a presentation next week at the PacSec Conference in Tokyo, describing the "mathematical breakthrough" that, he says, enables him to crack WPA-TKIP in 12 to 15 minutes. There are some limitations, as the data sent from a connected device to the compromised router is apparently still safe, but anything headed t'other way is wide open, and could even be supplanted by bogus bits sent from a Cheetos-munching hacker slouching in a rusty Ford Taurus in the parking lot. Don't believe us? Tews was the guy able to crack WEP in under a minute last year, ironically advising people to switch to WPA ASAP at the time. We can only assume WPA2 is next.

Elcomsoft uses NVIDIA GPUs to crack WPA2

by Nilay Patel posted Oct 13th 2008 at 10:58AM

Elcomsoft has been using NVIDIA's CUDA GPU computing architecture to accelerate its Distributed Password Recovery tool for a while now, but it looks like the latest version of the cracking utility takes it to the next level -- it can break a WPA2 password using two GeForce GTX 280-based boards 100 times faster than with just a CPU. It's still a brute-force crack, but only a few packets need be sniffed, and the GPU accelerates the algorithm used to generate keys significantly -- even laptop-grade 8800M and 9800M GPUs speed things up 10 to 15 times. We wouldn't worry too much about wardrivers with trunk-mounted bladeservers going nuts, however -- the base version of the software costs $599, and things ramp up to $5,000 pretty quickly.

Wi-Fi Alliance 802.11n Draft 2.0 testing begins -- certified products soon

by Thomas Ricker posted Jun 25th 2007 at 7:01AM

In a move meant to ensure compatibility across vendors, the Wi-Fi Alliance has started interoperability testing of 802.11n Draft 2.0 products. That means "WiFi Certified" products should hit for retail before summer is out. Besides sporting that swank new logo, the certification should provide some peace of mind related to WPA2 security, WMM QoS for video streaming, and compatibility with legacy 802.11a/b/g regardless of the manufacturer. While cross-platform certification testing of a draft spec is unusual and likely won't guarantee 100% compatibility, it's still a welcome step by the industry given the troubled history of interconnecting disparate 802.11 draft devices in the past. Besides, with the final IEEE spec (already two and half years in the making) not expected until September 2008, what else could Apple, Dell, Sony, Nokia, Cisco and the other 250 or so members do in the face of such mucho demand?

Actiontec unveils range-extending Wireless FMC Router for mobile / WiFi hybrid phones

by Darren Murph posted Jan 12th 2007 at 8:04PM

For those of you who happen to be in the predicament of owning a svelte hybrid cellular / WiFi phone, yet can't get cellphone service back in the boondocks where you reside, Actiontec is kicking out a range-extending router to help you make and receive calls on your mobile handset via WiFi. Touted as a "world's first," the Wireless FMC Router acts a standard four-port 802.11b/g/n router, supports WPA2 / WEP, and comes with a rather robust firewall to keep your conversations guarded from snoopers. Additionally, it facilitates call switching between the mobile and home WiFi networks as users move in and out of the house, giving you the option to connect via your cellular network or over VoIP with the same handset and same number. Aside from acting as a "middleman between the broadband and cellular networks," it can connect / drop from the WiFi / mobile networks on-the-fly while conversing, and can purportedly support "all major carriers" as well. So if you're thinking of consolidating the amount of phone numbers attached to your name, and don't mind picking up a hybrid handset, this multifaceted router will be able to simplify your conversations for $179.99 when it lands in Q2.

SpectraLink unveils NetLink 8000 series of 802.11a/b/g WiFi phones

by Darren Murph posted Jan 11th 2007 at 6:27AM

For those of you who think VoIP just isn't good enough, or you manage an enterprise with hundreds of folks needing to yap it up simultaneously sans wires, you might be interested in SpectraLink's latest duo, which collectively claim the title of "world's first" 802.11a WiFi phones. The VoFi (voice over WiFi) handsets are part of the NetLink 8000 series, and both units feature 802.11a/b/g, WPA2 support for enhanced security, four programmable softkeys, audible / vibrating ringers, backlit displays, text messaging support via Open Application Interface (OAI), military grade shock resistance, speakerphone, and a software configuration tool to boot. The NetLink 8030 ups the ante by including dust / water resistance, rubberized grips for "improved ergonomics and durability," enlarged earpiece for noisy environments, and SpectraLink's "unique PTT feature." Both handsets should begin shipping during the first quarter of this year, and while the NetLink 8020 will run $595, the PTT-enabled NetLink 8030 will demand a whopping $675.
