Computers housing the world's most sensitive data are usually "air-gapped" or isolated from the internet. They're also not connected to other systems that are internet-connected, and their Bluetooth feature is disabled, too.
Sometimes, workers are not even allowed to bring mobile phones within range of the computers. All of this is done to keep important data out of the hands of remote hackers.
But these security measures may be futile in the face of a new technique researchers in Israel have developed for stealthily extracting sensitive data from isolated machinesusing radio frequency signals and a mobile phone. The attack recalls a method the NSA has been secretly using for at least six years to siphon data in a similar manner. An NSA catalogue of spy tools leaked online last year describes systems that use radio frequency signals to remotely siphon data from air-gapped machines using transceiversa combination receiver and transmitterattached to or embedded in the computer instead of a mobile phone.
The spy agency has reportedly used the method in China, Russia and even Iran. But the exact technique for doing this has never been revealed. The researchers in Israel make no claims that theirs is the method used by the NSA, but Dudu Mimran, chief technology officer at the Israeli lab behind the research, acknowledges that if student researchers have discovered a method for using radio signals to extract data from hard-to-reach systems, professionals with more experience and resources likely have discovered it, too.
Dubbed "AirHopper" by the researchers at Cyber Security Labs at Ben Gurion University , the proof-of-concept technique allows hackers and spies to surreptitiously siphon passwords and other data from an infected computer using radio signals generated and transmitted by the computer and received by a mobile phone. The attack borrows in part from previous research showing how radio signals.
The researchers in Israel have developed malware that exploits this vulnerability by generating radio signals that can transmit modulated data that is then received and decoded by the FM radio receiver built into mobile phones.
FM receivers come installed in many mobile phones as an emergency backup, in part, for receiving radio transmissions when the internet and cell networks are down.

It's not in a flasy case, but it looks sweet sitting amid my other AV gear, it doesn't create an noise and I just leave the perl scripts running on my MP3 server and forget about it.
Plus I can actually read the VFD from the couch. Oh yeah, I can also control the music from my web browser when I'm out of remote range. So I can be sitting at my computer with the stereo playing in the living room and I can have total control over it.
Way to cool! I was wondering why both the Audiotron and the Rio receivers were so large, when nothing that they do requires much hardware. Disadvantages include: Not available yet. Other reviews Score: 2 , Informative. I did a bit of a search on google, and came across other reviews. The cnet review [netscape. You've got to tell them! Re:You've got to tell them! We Have A Winner!
A much better alternative Score: 2 , Interesting. These guys [slimdevices. Re:A much better alternative Score: 4 , Insightful. Except this devices is hand-made in a garage in lots of a couple hundred each.
This isn't meant to disparage the quality, but as such it might not be available when you want it where you live. In fact the website says "The SliMP3 is not yet ready for sale. If you would like to receive an e-mail when our first units become available, please submit the form below. What is the point in streaming full quality Kbps digitally across my house only to lose that quality in the last few feet due to a cheap-as-you-can-mass-produce DAC?
I'd also like to point out there is a HUGE market for a similar device that can play video files, not just audio files. No one wants to put a computer in their home theater because it is too bulky and noisy. Wouldn't it be awesome to keep all your movies on a server in the computer room and then stream them to some small little elegant and quiet device just like these audio players?
I'd certainly pay for something like that. Parent Share twitter facebook. Re:A much better alternative Score: 2 , Informative. The "quality" difference is going to negligible, especially since you're already compressing it. Re:A much better alternative Score: 1. Everyone's calling this the "Poor-man"'s Audiotron. I wonder about that, since the UI on my Gateway admittedly running very old software is horribly slow, to the point of being unusable.
Same software dev team, btw. Re:A much better alternative Score: 2. It's true the website implies they're not available yet, however I have one since I wrote to Sean and asked nicely : I believe they have sold the hand-soldered batch and are now getting ready for the first contract manufactured batch.
Cheers, Chris Morgan. FYI, we've scaled up production and we expect our first batch of professionally manufactured players to be available by the end of December. It's more expensive because it's better, not because we're making them in smaller qty. Also we're using a high quality 40x2 Vacuum fluorescent display [slimdevices.
You want to target the high end consumer Did you ask your sample group if they'd rather have a plain old backlit LCD display but get the digital port? I know I would. How long is this device supposed to last? True, maybe there aren't a lot of people right now that have digital inputs on their stereo, but what about in a couple years?
Five years? Ten years? The explosive growth of DVD is causing a lot of people to reexamine their home theater systems and upgrade to digital sound. One possibility is maybe find a convenient place on the mainboard for an expansion card? So maybe you could find a place to put a few pins and then offer customers a digital output option? That way the price increase is minimized and those who want the feature can pay extra for it.
Thanks for the feedback. You clipped off the rest of my sentence and took it out of context. Everybody appreciates a high quality display, remote, and UI. Almost nobody would be able to tell the difference between an MP3 played through the player's DAC vs. I am acknowledging, however, that there is a significant portion of the market that would use the digital output. When you're designing cost-sensitive hardware, you have to make calculated decisions, taking into account what your customers want, what they're willing to pay, mechanical considerations, whether it's feasible to make it an add-on card, etc.
Trust me, I researched it very carefully. And the price for the slimp3 is already up there in the hard-to-justify regions. Disparaging flames aside, I think you're spot on about the video tho and there I could see the digital out for AC-3 sound being useful. The Slimp3 guys seem to have that on their roadmap, as this apparently is only the first incarnation of their all-singing all-dancing multimedia firmware. All that from reading between the lines, so YMMV.
Software Not Thought Out Score: 1. You can find out more about it at its website. Here's a picture for your viewing enjoyment Go to the SonicBlue on-line store [sonicblue. Hard coded MAC address? Score: 2. I'm curious as if he has to tell the software the receiver's MAC address or if its hardcoded into the software. Like me, I have a nice system in my living room, and a really nice system in the basement with the big screen.
Re:Hard coded MAC address? Not sure where the MAC address lives However, to address your last question: Yes, you can buy more than one of these units and use them on with a single MP3 server. The software clearly supports this. Score: 3 , Informative. FYI: Diamond Multimedia owns which allows them to have 16,, unique addresses. Why bother buying it. Score: 2 , Interesting. Meanwile this unit will at least set you back If a person is looking for a cheap stationary media player there really is no reason to go all out and get this thing.
The way I see it you have two options one put together a high end or beter with a network card that way you can stream all the mp3's you want from your other computers be they mac's win boxes or 'nixers.
Then conect the box to your hi-fi. For 40 dollars you can even throw in the option for a remote controller [evation. The other option that I came up with is, if your on a buget and you want somthing that plays cds,mp3s and what the hell even mpg video go buy your self a Dreamcast they go for as litle as 70 bucks [cnet.
With that you can do what ever you want even play doom. Re:Why bother buying it. The only reason I see is the box looks like a stereo component and not a computer, so if you can find it for bucks its not bad. I agree that it could do much much more then this.. Ah well though, bucks isn't bad. BUT, you don't get a network adaptor in that, and they are not easy or cheap to find.
They are also pretty noisy, compared to the Slimp3 mentioned elsewhere. It would be good fun to code the UI etc I don't understand. Does the Dreamcast play MP3s? I didn't know it would do that. That would be pretty cool. Can it read from the drive or do you have to make a linux boot and then read from the network? Re:software as w2K service? First, install Terminal Server on the 2K box. Then create a user that will run the audio manager software, and install the software under that user.
Put a shortcut to the audio manager. Then login to that user using Terminal Services; that'll start up the audio manager. As soon as the software is running, close the Terminal Services window -- the user will still be logged in, and the audio manager will continue to run as long as the machine is up. They simplify the process of making ordinary apps run as background services.
If the audio manager software is well behaved and if it doesn't require a user to be logged in for other reasons it might work. Nice review Score: 4 , Informative. I run it from an rlogin session running mp3blaster but, because it also runs Apache, I can set it up to broadcast music to every computer in the house. But wait, it gets better. Want more? Or do it via a news client and the usenet. As a bonus, I can ssh into my firewall, rlogin to the mp3 box, and wake my kids up in time for school from 1, miles away!!
I recommend rap for this. The only thing I haven't done yet is make it into a CD burner; I do that on my wife's machine under, I'm afraid, Windoze. But still, with a little bit of scrounging almost any Linux geek can come up with the same or better system for the same or lower money. The best part is that I'm the first guy on my block to have my kids yell at me, "Dad, will you turn that damn music down? That's cool. I do something similar.
I have an old Pentium with a 6Gig drive as my music server. It's possible those kinds of authorities would be helpful in going after these criminal groups.
However, finding the extortionists is a real challenge. Most of the criminal groups demanding ransoms from broadband providers want payment in the digital currency Bitcoin to help cloak their identities. Posner, the VoIP expert, says he's been thinking a lot over the past month about what needs to be done to defend the communications sector.
So it would be great if there could be some dedicated resources to help protect our infrastructure. On the other side, companies are going to have to come up with a response plan.
