Re: VeriChip hack? (Sorry if this posts twice)

[Shawn Fitzgerald <sargon97 () gmail com>]

I don't know anything about this specific hack but a lot of the RFID  
attacks that have been surfacing are not very interesting and/or new.  
They generally have to do with how the RFID is used rather than some  
problem with the tech itself. For example if some system implements a  
key by just broadcasting a code, well thats just stupid and it can be  
sniffed. If the system is using some sort of challenge response,  
thats different.

That being said some of the older protocol attacks such as relay  
attacks (i.e. grand-master chess problem) are VERY relevant for the  
typical RFID system. Also it still is not clear if RFID is less  
vulnerably to your typical side channel attack (e.g. DPA/SPA type).

bottom line is that one can look at the design and determine if the  
RFID is vulnerably to the typical attacks being published.

Cheers, Shawn
