Crashing A Nokia Phone Via SMS
Atryn writes "An article at the Register reports that a recent Black Hat conference presenter demonstrated how to crash Nokia cell phones using malformed headers in SMS messaging protocols. Though the SIM card can be recovered by moving to a new phone, this is perhaps an interesting preview of security issues as data goes wireless." Of course, when you live in the US, where your wireless services are about eight years behind the curve, this is less of an issue. *grin*
I just got back from India and Europe and am thoroughly embarrassed by our government's and wireless carriers' inability to play ball with the rest of the world. At least AT&T finally got the clue, I hope.
This talks about crashing a phone via SMS, but what about devices on CDPD or GPRS like those road signs or weather telemetry, or even electric meters in some locales. That's not only on the wireless network but on the IP network. Has anyone tried to muck with those devices yet? On most CDPD and GPRS plans the customer pays for each byte transmitted, what if someone just streams data towards a customer to run up their bill?
It's time to code firewalls and applicative filtering proxies for mobile phones...

So I guess the HandSpring Visor GSM phone I have with GSM service via Voicestream dosen't exist???
I thought nokia phones already shipped worms out-of-the-box.
Just like any technology, it can be used and abused. If I were the type who didn't like the word asshole, I might be justified in lamenting:
.. would you prefer to crack down on these people, and drive their activities into the underground where you are upable to keep an eye on them?
Is it at all possible to have any sort of message board without people coming along and using the word asshole?
Any other way, and you wouldn't be on planet earth, bub. Stop whining about it, and start questionting which you value more: crashable cell phones, or no cell phones?
Society must accept the inevitability of technology as an unbiased tool. Technology CANNOT be created for good. Like it or not, as a society, we must accept that when we adopted cell phones, we accepted the possibility that they may not always work, in the same way that as a society we value the use of cars more so than the lives of the thousands upon thousands of people who die as a result of them every year.
Anyone who thinks technology puts powers only in the hands of the righteous (whatever the hell that is) is a fool. In the case of Black Hats, I'd rather the concaine junkies in my neighbourhood congregate and do their thing in the middle of daylight in the park rather than at night, in allys, if you catch my drift. The fact that this was demonstrated at a conference is a good thing

Security through Inertia. Hmm...
Napster-to-go says "Fill and refill your compatible MP3 player", which is a lie. It's not MP3. It's WMA with DRM.
but in real life most of the US has just as good of coverage as Europe.
You obviously haven't tried using the same phone in both the U.S. and Europe. Get a tri-band GSM phone, take it to any large city in Europe, and you'll see you get much better coverage than in NYC/someother U.S. city.
Hi Slashdotters,
We here at Slashdot would like to advise you to use the following format when submitting bug-related stories.
"Crashing a [product] with [method used to crash it]"
"An article at [source] reports that [security expert] demonstrated how to crash [product] using [Pick one: buffer overflow; malformed headers; Javascript]." [insert wizened statement about how this will affect future direction of products in this category] [attach silly remarks by Slashdot writer like "Well, that's why I use [competing product]!"]
Also, please use the following template when replying:
"Those @(#&@! bastards! Who do they think they are, making [product] so buggy! Why do they have to include [useless feature that no one wants/uses anyway]?? I'll never use a [company] [product] again! Please, fellow Slashdotters, I urge you to boycott [company]!"
This will save us a lot of time and moderation points.
Thank you,
The Slashdot Team
"This phone has performed an illegal operation and will be shut down...if the problem persists, please call the vendor"....
Hahahahahaha...{sniff}....hehehe.
What is with the Grey screen of death comment being modded as overrated?
Geez, you'd think you would have to be rated first.
Maybe that should be submitted as a bug?
You can't fix the moderators who do that kind of stuff (maybe spayed or neutered) but can you fix the system?
Oh, well, don't worry, be happy..la la laaa
Have you read the moderator guidelines? Well, have you, PUNK? (and I want a Karma: Gnarly option)
It's probably not true that Europe is ahead because they have a standard system; as far as I can tell, they are ahead because it became fashionable in the boom of the late 80's in London particularly to have a cell phone; partly because it was a way of doing more business for the brokers- it quickly became a status symbol. A fairly affordable it became too as it grew rapidly among the city and top businessmen and filtered its way down to basically everyone.
The fashion made the economics look better, and that in turn drove more manufacturers to enter the market and compete, driving the price down further.
The other feature that killed off the other mostly non-digital systems was security. After the 'squidgy' tape loads of people would only get digital, particularly Prince Charles- and the GSM phones were a convenient digital standard to go for at that time.
Britain is an ideal place for cell phones- the population density is pretty high, so less cells are required; most people I know have a cell phone in britain. Many of them don't have a fixed line at all anymore.
Incidentally, there IS a satellite phone system- Iridium, last time I checked it was very expensive, didn't work indoors or in cities, had low quality; and the handsets are really heavy.
The military loves them.

"Gravity is only a theory, not a fact!"CDMA is a better standard than GMS overall
What I find funny about this statement is that these two are not necessarily comparable. CDMA is a radio protocol, used by both Sprint PCS and Verizon here in the USA. GSM, on the other hand, fully describes a wireless network, from the radio protocol (TDMA), to the included services (voice, 9600bps data, SMS), all the way to the SIM chip.
While CDMA may be a better radio protocol than TDMA, it is definitely not a wireless network. You can't use a Sprint phone on the Verizon network can you? As far as I know, these are separate networks with their own definitions. They just happen to share a common radio protocol.
So when someone brings up the ancient war: CDMA vs TDMA vs GSM, be sure to reorganize this into: Sprint vs Verizon vs AT&T vs GSM. This is a much more sensible comparison. Anyhow, perhaps in the future GSM's radio protocol can be replaced with a CDMA incarnation.
I concur!
Nostalgia was better when I was young too, I might add.
It's interesting that the people who have phones with text messaging find it extremely useful where as those who don't have it shrug it off with "I don't need no stinkin' text-messaging WAP shit", not even seeming to know what they are talking about, since WAP has absolutely nothing to do with text messaging and SMS messages.
Personally, I find SMS messages extremely convenient in very much the same way as email is convenient. It's a lot less intrusive than a phone call since it doesn't demand the receivers attention RIGHT NOW. It's quiet and more private, you can write and read SMS's anywhere without disturbing other people or other people disturbing you. You can use it for services. Send "FIND Joe Sixpack" to number 400 and you get the address and phone number of Joe Sixpack in return. Send "WEATHER Helsinki" and you get the latest weather forecast for the Helsinki area.
I worked in Singapore for six weeks last summer and it was extremely convenient to just bring my normal cell phone with me from Finland and everything working without any reconfiguration. Phone book entries, caller id, text messages, data. I used the phone to check my email with my Palm Pilot, Finnish news, Forumla 1 results riding home from work in a cab in the night etc.
I'm not saying that everything should be crammed into a cellular phone. Some things work better in a laptop or a PDA if you want it mobile. The point is that things like SMS and WAP, which are totally basic features of GSM phones, are quite useful and have their own place. Instead of silly "I don't need no stinkin' text messaging WAP shit on my phone" outbursts, you might want to try it out. You just might discover how nice it is and how well it works!
