Hackers Clone Passports In Driveby RFID Heist

pnorth writes "A hacker has shown how easy it is to clone US passport cards that use RFID by conducting a drive-by test on the streets of San Francisco. Chris Paget, director of research and development at Seattle-based IOActive, used a $250 Motorola RFID reader and an antenna mounted in a car's side window and drove for 20 minutes around San Francisco, with a colleague videoing the demonstration. During the demonstration he picked up the details of two US passport cards. Using the data gleaned it would be relatively simple to make cloned passport cards he said. Paget is best known for having to abandon presenting a paper at the Black Hat security conference in Washington in 2007 after an RFID company threatened him with legal action." Apparently this is a little unfair — he sniffed the data, he didn't actually make a fake passport.

    Seriously ... not tinfoil hats but around your wallet. These RFIDs seem to have greater range than advertised and that is a huge security risk for sniffing.

    Some sort of Faraday Cage will block RFID, or at least their power supply. I do not know whether ferromatnetics like iron and steel are more effective than non-magnetics like aluminum.

    Anyone with even minimal English fluency would understand this as saying that he collected the data but didn't do anything with it.

    We don't even need an automotive analogy, since the data was collected from one car by reading passport RFIDs in other passing cars.

      I believe the foil sleeve is actually built into the binding. My girlfriend got a new passport, and the cover and back are a lot thicker than the old passports. It seems that there is some extra layer in there.

    A cellphone has a powered transmitter, and a boosted receiver with a specialised antenna. An RFID chip must rely solely on the radio energy it receives to power itself up and transmit back, so I'm not sure that a cellphone is an adequate test.

    The signal power you're talking about for a phone is going to be so much higher, and likely at totally different frequencies.

    I think the only way to test it effectively would be to see if the RFID reader at the airport still works with the wallet, assuming the person working the desk doesn't mind you testing it out.

    I always keep my passport on me. I've stuck some plastic tinfoil (use an emergency blanket) inside the wallet pocket where I keep the passport.

    Note that you're talking about something completely different.

    The US passport CARD is different from the passport BOOK which you use in international travel. The passport card only works when traveling between the US and Canada or Mexico; it's not accepted anywhere else.

    If your passport BOOK is a US-issued one, you don't need the tinfoil because it's already built into the cover. Even if it weren't, the BOOK requires a cryptographic authentication using a key derived from data printed on the inside of the book, so someone has to either see the inside of your book or guess the data.

    The CARD does not require cryptographic authentication and has no closeable cover.

  11. Re:Why do passports need RFID? by swillden · · Score: 4, Informative

    Why not just use a smart card similar to the Common Access Card (CAC) used by the U.S. Department of Defense [wikipedia.org]? Those things can store a lot of data, are very easy to use, and cannot be hacked remotely via RFID equipment.

    The chips in passport books (not cards) ARE the same sort of device that's in the CAC. The old CAC cards are contact-only, which doesn't work well for a passport book because it would be difficult to build a reader. The CACs are being replaced by PIV cards which are dual-interface (contact and contactless).

    Other than the contact vs RF interface, though, these so-called RFIDs in passport books (not cards) are exactly the same sort of technology as CAC cards. The chips have plenty of storage and provide cryptographic authentication capabilities.

    It appears that a different, longer-range technology with no cryptographic authentication requirements was used for the passport cards.

    Don't get one. Get a passport book. It costs a little more, but it can be used for visiting countries other than Canada and Mexico, and it doesn't have these security issues.

  13. *US Passport Cards*, not real passports by lobsterturd · · Score: 2, Informative

    It's absolutely worth noting this is about cloning US Passport Cards, which are completely useless outside the US, not real passports.

    Passport Cards use a simple RFID system (EPC) where the chip simply spits its ID number out.

    Passports, on the other hand, require a reader to authenticate by passing a hash of (passport number, date of birth, date of expiry). I don't think that's nearly enough information to ensure security, but at least it's better than nothing.

      It's also important to note that real U.S. passports actually have shielding (effectively, a Farraday cage) built into the covers so that the RFID chip is only able to be powered and transmit when the passport is opened.

  15. This is exactly why... by Jane+Q.+Public · · Score: 2, Informative

    this kind of technology makes people and their information LESS secure, rather than more. Because it makes it far too easy to read someone else's information and clone it.

    The RFID Nazis will be quick to tell you that there is also a unique encryption key in the passports, but as has been pointed out elsewhere, only 5 of the 45 signatory nations supply their keys to the international database, and as long as any of those 45 nations fail to do so, the keys are meaningless because it is possible to clone passports from any of the non-compliant nations.

    And we KNOW that it is possible to physically duplicate passports effectively... after all, that was the justification for using RFID in the first place. So that isn't an argument.

  17. Re:Tinfoil is the answer. Seriously! by swillden · · Score: 2, Informative

    Assuming the document ID (any identifiable string) can be determined at a distance, yes.

    There are two solutions to this. The first is the fact that the RF technology used by these chips does not work well at long ranges. In lab environments it's possible to get distances of up to a meter, but in the real world the limit is around 10 cm, assuming nothing is between card antenna and reader antenna (and assuming reader antenna is a high-gain type). The super long-range stunts you read about use a battery-powered repeater placed within a few centimeters of the card.

    Note that the above applies to the passport books. I'm not sure what the passport cards use, but it appears to be a different RFID technology which supports longer-range operation. It's highly likely that they also do not contain the same level of personal information that is in the books, simply because the 900 Mhz RFIDs (unlike the 13.56 Mhz contactless smart cards) don't provide the same storage capabilities.

    The other solution is ATR randomization. When powered by the reader field the chip transmits an "Answer To Reset" which includes some unique identifying information. Many researchers have called on the ICAO to specify that this should be randomized, exactly to prevent the sort of thing you describe. Manufacturers produce chips that do randomization. AFAIK, the US state dept. is not yet using them, although it's not unlikely that within a few years there will be no chips on the market that do NOT randomize their ATRs.
