New Controversy over Black Hat Presentation

Posted by Zonk on Tue Feb 27, 2007 12:07 PM
from the black-hat-on-a-white-field dept.
uniquebydegrees writes "InfoWorld is reporting about a new controversy swirling around a planned presentation at Black Hat Federal in Washington D.C. this week. Security researcher Chris Paget of IOActive will demo an RFID hacking tool that can crack HID brand door access cards. HID Corp., which makes the cards, is miffed and is accusing IOActive of patent infringement over the presentation, recalling the legal wrangling over Michael Lynn's presentation of a Cisco IOS hole at Black Hat in 2005. Black Hat's Jeff Moss says they're standing by their speaker. A news conference is scheduled for tomorrow AM." Update: 02/27 20:10 GMT by Z :InfoWorldMike wrote with a link to story saying that the presentation has been pulled from the slate for Black Hat, as a result of this pressure.

    So what is this "hack"? Recording and replaying the serial is nothing new.

        The BlackHat speaker isn't presenting it as new...what he *is* doing, though, is giving away schematics to build devices to do the reading and cloning. That's what's getting HID's attention. Lots of people knew you could do this...not so many had a clear schematic & parts list to actually go *do* it.
      • I may be wrong in assuming this, but it seems likely that the security system would detect a brute force attempt pretty quickly.

        Even if it doesn't, halfway competent security staff would notice the attempt right away. One of the guys here showed me how their monitoring system works once - any time someone uses an invalid card (whether it's deactivated or just doesn't have access to that door) or the door is held open too long, or anything else out of the ordinary happens, the security cameras take snapshots

      Basic HID Prox cards just report a serial number. HID also makes a version that has some cryptographic component, called iClass. When I spec'd a security system last year, I insisted on crypto-enabled cards and readers. (We ended up with HID's iClass.)

      If this is just a tool to clone HID Prox cards, then it's nothing new... but it'll make me look good to my boss. (Sweet!)

      If it's a tool to spoof iClass readers then it's new, a pretty big deal, and I just wasted a few thousand bucks. (Boo!)
       
      • It's not really anymore broken than a regular pin and tumbler key lock. Sure, with this you can copy somebody's key by walking by them, but I bet it would be pretty easy to get an image of a key in somebody's pocket too... Just an IR camera would probably do the trick.

        At least with the RFID system, if you try to brute force the door it can disable access and call the cops after a certain number of failures. You can try keys off a ring, or pick at a physical lock all day as long as nobody happens to see you.
        • Sure, you could make this a lot more secure, but it's not any worse than regular locks. It's basically the same as regular locks but with easy revocation.

          And with a huge false sense of security. Oh, and it costs a lot more.

          So, exactly what's the benefit again? Aside from the fact that employees can act all cool, by waving their badges at a sensor instead of sticking a metal piece in the door?

      I think part of the reason for this (besides the obvious penis-length contest, which is definitely true -- IIRC what's important isn't what's printed on the cards so much as the color, e.g. white for USG employees, pink for contractors, etc.) is because you're told in security training to always keep the cards on your person, and not put them in a laptop bag / briefcase / purse.

        I think the solution is just to issue everyone a metallic container, which slips over the card and covers the portion of it that contains the antenna. Maybe you could even design one that would reveal (through a clear front) the name and picture of the bearer, but cover the back of the card and keep it from being read.

        How about just use magnetic stripe cards? The only way to read it is to physically slide it through a reader.. if you have to 'open' your RFID card to get the reader to recoginize it, then it's just as simple to slide it through a reader on the wall, but probably much cheaper.

            You know, in fifteen years of carrying a credit card, I have never had one fail. The high-coercivity mag stripe cards are darn near indestructible. By contrast, the low-coercivity cards that they use at some hotels... I've had them just suddenly fail on the third or fourth use and have to be reprogrammed multiple times in a single night (and about the fifth time I had the same card reprogrammed, they tossed it in a trash can and programmed a fresh one for me, which never failed again).

            Put simply, low-coercivity cards suck, but high-coercivity cards are pretty solid. Just don't cut corners on your card programmers and you'll be fine.

    This blows me away. Rather than taking the responsibility for having a flawed security system, rather than having the responsibility as a company to say "Hey, yeah we know about this and we are going to fix it after 15 years," the company accuses the security researcher of a lack of responsibility for "revealing" how to exploit these systems.

With Internet-connected servers, anyone who has access to the Internet is a potential attacker, knowledge of a vulnerability (i.e. automated exploit software) can spread extremely quickly, and it's easy to hide behind surrogates (i.e. proxies, botnets, etc). With door locks, the pool of potential attackers is a lot smaller, and the personal risk for an attacker is much greater.

    The article and this guy on the video seem to be confusing RFID and Proximity (125khz).

    Its really odd to hear them mention you'd need to bring the card up to 2-3 inches to the reader, when they keep talking about RFID.
    Its clearly proximity.

    Also the fool on the video mentions this as if its new, numerous websites mention how to do this and have for years.

    Proximity has its draw backs and EVERYONE knows this.

    Which is why HID HAS addressed it with new products. HID iClass readers. 13.56mhz, with Encryption between the card and the reader. After 2 roll-overs of public to private encryption keys, you no longer can just read the card with any reader you actually need to know the private key.

    So:

    RFID not what they are talking about.
    RFID /= Proximity
    RFID should not be used for access control (unlocking doors from 5 feet a way... seriously...)
    Proximity vulnerable (nothing new)
    HID iClass (13.56mhz proximity with Encryption) HID has a solution (makes me wonder why they never mention it though...)

    We're able to make copies of keys, yet they're still widely used as "security" measures in offices worldwide. Why is this any different? I've always been taught that a successful Security strategy is comprised of the 3 concepts:

    What you have - your ID badge/card
    What you know - the PIN associated with that card
    Who you are - a fingerprint/retinal scan/etc to be used with that card

    The point is, ok, someone figured out how to easily clone RFID enabled "access cards". Is it the manufacturer's fault that many places rely SOLELY on those badges for their perimiter/access control? If your facility is truly "secure", there should be at LEAST the requirement of a PIN typed in along with a card swipe as well as cameras, physical security, and other standard procedures. If your facility's management has opted to rely on the cards as the only means of controlling who enters and when, then blame that same management if a problem happens. The term "security" is very subjective. What might pass for your average office building would never pass at a serious Datacenter or other Critical Facility.
