The presentation slides by Bishop Fox at RFID Hacking - Live Free or RFID Hard - 01 Aug 2013 – Black Hat USA 2013 – Las Vegas, NV briefly describes a number of RFID hacking approaches, and ends with a picture and statement about the sleeves that are now distributed with United States Permanent Resident Cards ("Green Cards"):
USA - Green Card Sleeve • Since May 11, 2010, new Green Cards contain an RFID chip • Tested Carl’s “protective sleeve”, doesn’t block anything. • False sense of security
But details are hard to come by.
- Does the official sleeve provide any protection? Has it been quantified?
- What alternative protective shielding alternatives might work better?
- Which RFID technology, protocol, etc is used by Green Cards?
- What are the privacy and security risks of using Green Cards with or without the official sleeve, or others that might be recommended?
