The exploit involved the very powerful (500KW) Aspidistra transmitter, coupled to a directional antenna farm. With that power, they could make it sound like a local station in the target area.

With a staff of fake announcers, a fake German band, and recordings of recent speeches from high-ranking Nazis, they would smoothly switch from merely relaying the German network to emulating it with their own staff. They could then make modifications to news broadcasts, occasionally creating panic and confusion.

German transmitters were switched off during air raids, to prevent them from being used as navigational aids for bombers. But many were connected into a network and broadcast the same content. When a targeted transmitter switched off, Aspidistra began transmitting on their original frequency, initially retransmitting the German network broadcast as received from a still-active station. As a deception, false content and pro-Allied propaganda would be inserted into the broadcast. The first such "intrusion" was carried out on March 25, 1945, as shown in the operations order at the right.

On March 30, 1945, "Aspidistra" intruded into the Berlin and Hamburg frequencies warning that the Allies were trying to spread confusion by sending false telephone messages from occupied towns to unoccupied towns. On April 8, 1945, "Aspidistra" intruded into the Hamburg and Leipzig channels to warn of forged banknotes in circulation. On April 9, 1945, there were announcements encouraging people to evacuate to seven bomb-free zones in central and southern Germany. All these announcements were false.

The German radio network tried announcing "The enemy is broadcasting counterfeit instructions on our frequencies. Do not be misled by them. Here is an official announcement of the Reich authority." The Aspidistra station made similar announcements, to cause confusion and make the official messages ineffective.

Jon used a desktop computer attached to a GPS satellite simulator to create a fake GPS signal. Portable GPS satellite simulators can fit in the trunk of a car, and are often used for testing. They are available as commercial off-the-shelf products. You can also rent them for less than $1K a week -- peanuts to anyone thinking of hijacking a cargo truck and selling stolen goods.

In his first experiments, Jon placed his desktop computer and GPS satellite simulator in the cab of his small truck, and powered them off an inverter. The VAT used a second truck as the victim cargo truck. "With this setup," Jon said, "we were able to spoof the GPS receiver from about 30 feet away. If our equipment could broadcast a stronger signal, or if we had purchased stronger signal amplifiers, we certainly could have spoofed over a greater distance."

During later experiments, Jon and the VAT were able to easily achieve much greater GPS spoofing ranges. They spoofed GPS signals at ranges over three quarters of a mile. "The farthest distance we achieved was 4586 feet, at Los Alamos," said Jon. "When you radiate an RF signal, you ideally want line of sight, but in this case we were walking around buildings and near power lines. We really had a lot of obstruction in the way. It surprised us." An attacker could drive within a half mile of the victim truck, and still override the truck's GPS signals.

Italian free space optics test hits 1.2 terabits per second (in Italian, Google translation): Researchers in Pisa, Italy, along with colleagues from two Japanese institutions, crossed 1.2 Tbps in a test. Free space optics typically uses infrared lasers, and can work over a distance of kilometers.

More Canadian Wi-Fi health fears: This time in an island in Montréal. One of the concerned citizens: "This is something that is really under the radar. People do not know that long-term health hazards are associated with wireless technology." They don't know that because all verifiable, repeatable, well-conducted, academic tests so far indicate that there's no such health hazard associated with EMF. The concerned folks are raising an alarm about Wi-Fi being broadcast island wide, but are not paying attention, obviously, to the AM/FM radio, satellite radio, cellular, cordless, and thousand other wireless uses that are bombarding them right now, often at far higher signal levels.

Wi-Fi in a tub: I'm not going to say anything more.

QuickerTek adds antenna to 300 mW ExpressCard for MacBook Pro: Users of Apple's higher-end laptops can drop $200 to get a 300 mW Draft N (802.11n) ExpressCard and 5 dBi external antenna with a mounting clip. That's a lot of power, and it's important to recall that have a louder signal doesn't mean that distant base stations can necessarily hear you better. Draft N devices typically pair better listening (receive sensitivity) with higher transmission power, however.

Mac product ties location settings to Wi-Fi position: Centrix has updated its $29 Mac OS X location preferences program NetworkLocation to take advantage of Skyhook Wireless's Wi-Fi positioning data. You can now tie the package of settings that control what email account you use, iChat status, programs launched, disks mounted, and other factors, to where you're currently at.

Following in the footsteps of social networking projects like Intellipedia, A-Space, an online collaboration environment for intelligence analysts, will go live on September 22. A-Space allows analysts to share information, form communities, and work together all under one environment. The analysts from sixteen intelligence agencies will have access to shared and personal workspaces, wikis, blogs, widgets, RSS feeds and other tools, as well as be able to search for content on other agencies’ data sources and even on data that allied countries might share.

Karen Sage, Cisco’s director of product management for network management, said that it’s “actually a good thing when network management is struggling, because is say that innovation is really happening at a fast rate”.

Joe Weinman, Strategic Solutions Sales VP for AT&T Global Business Services, created The 10 Laws of Cloudonomics. Weinman expands upon his laws by comparing public utility cloud services, traditional data center environments and private enterprise clouds.

I’m not making this up. HP has a new reality show coming out. “Engine Room” will be broadcast on MTV and on the Web and will feature teams of designers from around the world who understake a series of challenges with the help of HP computers. Can’t hardly wait.

Apple added access for iPhone and iPod touch users to a subset of its iTunes Store over Wi-Fi--the awkwardly named iTunes Wi-Fi Music Store--more than a year ago, along with the ability to access that store at no cost from handhelds and laptops via Starbucks outlets in New York, Seattle, and throughout the San Francisco Bay Area. (Chicago and Los Angeles have been "coming soon" for a year, but the new AT&T/Starbucks deal may have delayed opening up those markets.)

Terrestrial AM/FM radio stations would like to figure out how to remain meaningful in a world of streaming Internet radio. Their latest strategy is to embed information that allows a listener to mark a song they want, potentially getting a piece of music sold in this fashion. With FM tagging, Zune players tap into an existing very low-data-rate encoding protocols that allow stations to push out their call letters and current song information. By adding a very short code, broadcasters can allow Zunes to look up the appropriate song.

At launch, 450 stations from major networks, including Clear Channel, Entercom, and others, will broadcast tagging details. Note that Microsoft includes KEXP, a Seattle independent and alternative radio station, in its sample image, for the new models. KEXP, given a boost a few years ago through significant short-term funding by Paul Allen--funding that involved changing its call letters to his Experience Music Project museum initials--has an enormous listenership over the Internet ironically enough. KEXP will be a programming partner creating channels of music for the subscription-based Zune Pass service. (Zune Pass is $15 per month, all you can eat.)

This option could allow Microsoft to ink partnerships with hotspot networks to brand them with Zune compatibility, lets radio stations promote something other than iPods that they would have a direct relationship with (and, potentially, some kind of revenue stream from?), and may be part of breaking Apple's digital music hegemony. May be. Nobody's gotten rich betting against Apple for the last several years. (Details of revenue sharing with radio stations hasn't been discussed.)

Apple opted for a partnership with HD Radio broadcasters and equipment makers that has a relatively elaborate process of tagging songs. HD Radio is digital AM/FM, a patented and licensed method that has provoked a lot of controversy, and has lagged enormously in the marketplace, despite well over 1,000 stations (including many public radio stations) broadcasting in this digital format, some for over three years.

HD Radio tagging requires an HD radio receiver with a Tag button; pressing that button stores the song's tag information. The radio must also have an iPod dock. Docking an iPod syncs the tag information, and the next time the iPod is sync with iTunes, you can see which songs were tagged. Kind of tedious compared to "press a button while listening to an FM station and buy the song over Wi-Fi." (I've been writing about HD Radio for years, and even launched a blog that's gone moribund; the technology is interesting, but Internet radio on mobile devices coupled with on-demand music purchasing over cell and Wi-Fi may simply make HD Radio unnecessary for listeners.)

Microsoft has a more compelling "marketing story" for this feature than Apple, that's for sure. On the other hand, do you really need to tag songs from stations that play only the most popular music in a given format?

"consumers hate tokens."

"Everyone wants to be the single federation platform for everyone else."

"Federation will never work. It won’t work because the single most important consumer Web applications in the world are scared of it. Banks hate the concept because it becomes a weakest link in the chain problem."

"Tokens don’t actually solve most security problems, like man-in-the-middle, phishing, and keystroke-logging malware."

"Oh yes, and finally, consumers are going to have to carry around 13 of them just to make sure they can log into whatever they need to log into since no one will federate."

"Global federation is nowhere near a solid concept in the consumer space, despite what the vendors will try to sell you."

"This is a long term problem. If you work on it and make any progress against it, you'll find yourself much smarter at the far end, than you were at the near end.

When I was in Norway about 5 years ago, I was there very close to the summer solstice. I was wandering around town at 2 o'clock in the morning and there was plenty of light out. You come to a sign that says New Minsk about 60 km and it points south.

And I ask the lady "what country is this?"

She scratched her head for a bit, and said "well I think its Norway"

I said "well who plows the roads?"

"well Norway does, but he have to pay them."

There is a triple boundary in this town that I was in between Norway, Finland and Russia.

But what I did there, was, I had a card about wallet size, I stuck it into a machine, I punched in four digits, and it gave me about 2,000 krone, whatever the hell that is.

Now there are a lot of participants in that transaction. When I put a card into that machine, punch in a pin, and it gurgles for awhile, and finally gives me, a fairly large amount of money. There are a lot of participants in that transaction. The bank that owned the machine that gave me the money, it gave some money away -- that bank wants it back. The pin is necessary to convince my own bank that I'm me. But I don't want my pin to be broadcast all over the world. My bank in the us, it hasn't really given out or taken in any money, really. But there is a lot of credits involved here. Somebody needs to charge somebody else for having more money available. Even though there was actually no cash transfer.

And the problem that I have in mind is
- who are all the participants in an ATM transaction?
- what do those participants need to satisfy their problems?
- how is that in fact done?

In a general way, does the atm system actually work in some reasonable sense? To which the answer is by the way: yes. The atm system damn well works. With extremely high reliability and accuracy. It surprises me. Its quite a bit different than voting machines.

Buying a lemon is always a bad thing – but when you pay $1 billion for it?! Back in 2005, Google bought a 5% stake in AOL for $1 billion and now is calling that investment “impaired”. That’s one way of putting it, so it’s a good thing Google has money to burn.

At LinuxWorld this week, Bob Sutor, VP of open source and standards at IBM, said that the next 10 years is “do or die” for open source software designed for specific industries. 10 years? That’s like 70 years in open source development time.

And finally…8/8/08…the Olympics are here! Network administrators around the world, except for Terry Childs, will be eyeing office network bandwidth closely as people go online to watch streaming video of the games. NBC and Microsoft will offer 2,200 hours of live video coverage with up to 20 simultaneous live streams of different events. Plus NBCOlympics.com will offer 3,000 hours of on-demand video content. The time difference means that much of the primetime events will be broadcast while the Western hemisphere is supposed to be hard at work. Me – I’m just glad it’s the weekend, and I can get the Olympics fix I’ve been waiting years for.

Who doesn't remember the cone of silence from the original Get Smart TV series.  Whenever Max and the Chief had something important to discuss they would lower the cone of silence so that no one else could hear them or eavesdrop. So it is only fitting with the recent release of the Get Smart movie, Meru Networks has released a wireless cone of silence.

Meru is one of few stand alone wireless companies still hanging on out there.  So they need to be innovative to survive.  Their latest product, RF Barrier puts antennas around a physical plant to dampen and make it impossible to to listen in on wireless data exchanges.  They claim this is a first of its kind.  Thinking about it though, I don't see a big barrier to other companies having similar technology. I don't think you have to be a genius to broadcast traffic that puts out "noise" to hide legit traffic. I think the real special sauce is that this works in conjunction with Meru's other security products like wireless firewalls and secure access points.

With Motorola's recent purchase of AirDefense is having wireless IPS soon going to be table stakes in the wireless provider game?  I think it is and while Meru's RF barrier is a nice story, they are going to need to have some sort of IDS/IPS in their product line to keep up.
