| RFID hacking tools released |
| Friday, July 30, 2004 at 00:02 by Rich Kavanagh |
Radio Frequency ID, or RFID as it is more commonly known, is being developed without security in mind.
RFID will be used by retailers and stock controllers to improve inventory control and make it easier to track sales. RFID tags have commonly been used to inject into dogs, should they become lost, the tags could contain the owners address or contact details.
Manufacturers are also experimenting with "fabric tags" that can actually be woven into clothes.
There are a number of privacy issues already surrounding RFID however, with some people claiming retailers could "track" customers and the products they bought, even by people simply walking past their shops.
Well today, those fears might become almost a reality.
During the popular Black Hat Briefings security conference today, a new open-source product called RFDump was demonstrated.
RFDump is a tool that allows you to not only read RFID tags within range, but more worringly, you can actually change and alter all the data stored in the RFID tag.
The RFDump project is sponsored by German based DN-Systems.
Lukas Grunwald, CTO of DN-Systems said,
"It is only a matter of time before smart tags replace the good old bar code. It is only a matter of time until everybody will wear at least one RFID tag. But you can exploit nearly all of these benefits."
As RFID can only store 128 bytes of information, the tags have no room for encryption. This means tags can be read by anyone with a suitable RFID tag reader and easily modified using RFDump.
Retailers could easily edit your RFID tags to add or edit any information they see fit and even track your shopping habits or locations.
On the bright however, you could always just overwrite the data on your RFID tags with some random numbers.

| As stated in the articles, RFID can only store 128 bytes of information. There is not really enough room for encryption.

| rfid is a revolutioary break through as demonstrated in the article by e-life, with seriuos finding this could be the next route in retail tech juss imagine its use in the singapore port |

| This RFID thing is crazy, but as far as me, probably the first thing I will do is create something to block the signal because I do not care what anyone says the gov probably has something somewhere that can read those tags from long ways away, believe me when I say our governments are way smarter then you realize. I read the MIT project site and berkleys and other schools and these nuts are coming up with some real far out scifi technology, but it is funny( wink ) that they can't even cure acne or the common code and everyone that even get's close to curing cancer just becomes of the missing, Wow what a world we live in. Sooner or later we will all be little James bond types because these republicans are destroying freedom & I will never be a slave of this crap or any kind of mouse for there crazy gov experiments. |
