The Study of Physical Hacks at DefCon 299

Posted by Zonk from the old-ways-are-the-best-ways dept.
eldavojohn writes "DefCon usually focuses on electronic security, but Saturday a talk was held that focused on possibly the oldest form of hacking — lockpicking. As software security becomes better and better, the focus may be shifting towards simple hacking tips like looking over someone's shoulder for their password, faking employment or just picking the locks to gain access to the building where machines are left on overnight. From the article: 'Medeco deadbolt locks relied on worldwide at embassies, banks and other tempting targets for thieves, spies or terrorists can be opened in seconds with a strip of metal and a thin screw driver, Marc Tobias of Security.org demonstrated for AFP ... Tobias says he refuses to publish details of 'defeating' the locks because they are used in places ranging from homes, banks and jewelers to the White House and the Pentagon. He asked AFP not to disclose how it is done.' I'm sure all Slashdot readers are savvy enough to use firewall(s) but do you know and trust what locks 'physically' protect your data from hacks like these?"

            You mistake shooting a "burglar" for penalizing said burglar instead of SELF-defense. Defending yourself is not to be confused with lynching.
            A "burglar" (intruder) is a huge risk to the occupant of a house because the intruder has incentive to kill the householder to shut him/her up, and sometimes does.
            Crimes of opportunity in a home invasion include rape, torture, arson to cover up the evidence etc.
            Intruders are not typically like Roger Moore in "The Saint".

            If you don't want to defend yourself, it is your right not to. To say that I cannot defend myself is to say that I don't matter, and those who would violate me do. I respectfully disagree.
            Even in Iraq, the US allows householders one firearm. This is because police response is reactive, not preemptive. All the cops can usually do is collect evidence and maybe arrest the perp for whatever he/she did. This neither does not reverse or prevent damage to the victim.

            When I was TDY to Saudi Arabia, some crackheads decided to party on my property. My wife asked them to leave. They told her to fsck off and made threatening statements. (We lived in an area with light police protection and long response times.) She retreated to the house, got our our Mini-14, and put several warning shots into the ground (not towards the crackheads) where the bullets could be retrieved if required. They promptly left and never returned for the remaining three years we lived there. When the police finally responded, the officer was fine with it. (I love the South!

            The right to violent self-defense is essential to freedom, because if you are forbidden to defend yourself anyone can do their will to you.

              Agreed.

              IMO, any rational burglar will attempt to flee once he or she discovers that the residence is occupied and the occupant is armed.

              Any burglar who does not flee once the occupant announces that he or she is armed loses the benefit of the doubt in my book. The burglar is clearly involved in an illegal act and is not making an attempt to flee when discovered. That is not a good sign, and the occupant is justified in assuming that his or her life is threatened, IMO.

      One summer I was forced to park right in the same neighborhood as crack houses, etc, because of where I had to work. As did my co workers. They all locked their doors and trunks, result, all of them got busted glass and popped trunks. I warned them too, I really did, I said "look at reality, these cars are targets now". Nope, none of them listened. I left my doors unlocked and the trunk slightly open, just eased down. The ride was so old and ratty I wasn't afraid of it getting stolen, albeit that was a chance. There was nothing left in the car to steal, a very cheap in dash radio not even worth a dollar at a pawn shop, but I made it easy for the crooks to ascertain that, because I knew they would look.

      From what the original poster's article said, this appears to be a valid method against the original Medeco and the Medeco Biaxial line [1], but I don't see how this would have any effect at all versus the latest Medeco3 mechanism (well, latest since 2003), which uses side bitting on the key as well as the usual Medeco rotating pins.

      Other than Medeco, there is one type of lock that would be excellent for security, Abloy's Protec line, which from what I read takes 10-12 hours to pick even for the pros at detainer disk type of locks. However, the Protec line isn't sold in the US. Older Abloy lines are decent, but it would take far less time for a pro to pick them open. There are other high security locks out there, and one can read from a lock site what the weaknesses are of each of them.

      Nothing is 100% secure. If some thief is determined enough to bypass something, they can.

      Lastly, high security locks just one tool, in a toolbox of security options. If its worth locking with a high security cylinder, its worth having a centrally monitored alarm system (with a duress code [2] option.)

      [1]: Biaxial isn't that much more secure than the original Medeco, but it allows for (IIRC) 10 times as many key combinations, allowing for more flexible keying options.

      [2]: Yes, home invasions are on the rise, so make sure an alarm system has a duress feature (where it disarms, but silently calls the central station)... and USE the alarm. If at home, use the alarm's "at home" feature which monitors the doors and windows, but doesn't arm the IR detectors. A high security lock is no good when it is opened by the owner at gunpoint.

          The OP's article really didn't have much detail, but there are other sites that one can check out that have more details on attacks on Medeco locks.

          The Medeco reward I've heard about in a number of different forms, so I'm not sure the exact details. Last I heard, if someone can pick 3 Medeco cylinders (the six pin type found in deadbolts, not the four or five that are used as replacement for disk tumbler cylinder replacements.), they get a prize. However I have no clue what the real status of that is.

          Nothing is unpickable by someone who knows their stuff and has the manual dexterity. Its slowing people down, to where even a skilled lock manipulator will take hours to open the lock, which will most likely mean detection. Its also forcing someone to leave a signature (scratches), so if stuff does get taken, one can prove to an insurance company that a lock was defeated or something was broken.

          Mushroom pins help, but are just one security mechanism, forcing locksmiths to jam the pins up, then let them float downward to the shear line, rather than pushing pins up from their resting place. I'm pretty sure the sidebar is pickable by some tool that rotates the pins, as its talked about on various lockpicking sites.

          This is one reason I recommend high security locks. If someone kicks down a door or breaks a window, that leaves a noticable signature where a claim with insurance has more ground. If someone's house is robbed by a bumped lock, there is no trace, and it goes to a word against word thing to prove that stuff was there, and is now not.

          It may be the security has nothing to do with the tumbler mechanism. In some locks are weaknesses that have nothing to do with the cylinder used. For example, one lock I have has a very pick resistant cylinder, but one can use a shim and the lock pops right open.

          Lastly, some people may state security through obscurity, but I'm glad that the methods of opening Medeco deadbolts are not made public. Physical locks can't be updated like most programs can. Every cylinder in a building would need replacing, and that would amount to hundreds of thousands, if not millions of dollars, factoring in parts, labor, the time it takes to deploy a new keying system, getting the new keys to all the employees, etc.

    The cuts in the key are individually angled so they rotate the tumblers as well as lifting them. Slots in the tumblers are lined up by the rotation to unlock a sidebar that fits into a longitudinal slot in the cylinder.

    Bump keys can't even get started opening that.

    More burglars have feet than have lockpicking skills. Step one in physical security is to combat kick-in attacks. Replace your strike plate, which I can almost guarantee is inadequate, with a reinforced model like the Mag-3 and most important, install it with #10 wood screws at least 3" long, so it can't tear out of the studs when subjected to a good kick. Predrill the holes and put soap on the threads so you don't break screws as you install it.

    A block watch is a great idea too. Neighbors are a security mechanism.

    An alarm system also protects you against fire, which depending on where you live can be a bigger threat than burglary.

In Poland criminals didn't even bother to pick locks to apartments half the time, they simply found some old lady carrying groceries to her apartment then offered to help carry them for her. Then as soon as she opened the door they punched her

    That's what encryption is for. Even with physical access, your files are secure as long as the key lives inside your brain.
    Of course they can then be deleted, but someone who would have access to my computer could only "damage" my most precious data, not read it. A computer does not work like a safe, it can be much more efficient.
    • I'm currently managing a transition to using only encrypted file systems, using loop-aes. As the parent says, one reason to use encrypted file systems is protection against burglars. The access keys for the data disappear as soon as the power is disconnected, so the burglar gets the hardware but no data. Thieves have to be unusually smart if they want to copy the plaintext - they'll have to trick you into revealing the key to them somehow.

  • Where I live we've had our share of "be wary of lockpicks" type campaigns. I've had my eyes on the "RFID Digital Door Lock"* from ThinkGeek for some time, and thought that maybe this would be the thing (except I rent my home, so it's not really my door to drill holes in). At least, it ought to be difficult to pick; it would be just as easy as ever to just bust in the entire door.

    Are there any slashdotters out there who have actually bought and tried this lock? Any good/bad reviews to be had?

    The Dell key-logger hoax has probably the best decoy story to move
    professional hackers/security staffers into the wrong direction, as in
    May 2006, USENIX published the following research article :

    In it the authors demonstrate that todays unwarranted wire tapping NSA
    activities, normally don't result in much success as serious internet
    users routinely apply encryption into their communications, like IPSec
    tunneling, ssh, VPN access connections, secure web-traffic https when
    i.e. doing Internet banking activities.

    However, secret service found a clever approach to all this, by
    covertly installing a Keyboard JitterBug into your keyboard. Here's
    how to secure your most trusted keyboard :

    where i may add, that lock picking _ALSO_ has been the best hoax ever
    on public display. Why? How many people today design their _OWN_
    locksmith locks? All installed door-locks worldwide are somehow sold in
    stores, hence its products and replacement keys are in the archives of
    the local secret service.

  • Tobias says he refuses to publish details of 'defeating' the locks because they are used in places ranging from homes, banks and jewelers to the White House and the Pentagon. He asked AFP not to disclose how it is done.

    I remember reading about how most locks can be easily defeated using a technique called bumping [wikipedia.org]. This site [toool.nl] also has PDFs and videos describing how it's done. Also searching Google for "bumping" gives you a lot of information on the subject, so unless this is something radically new, I don't

    See tobias's post on engadget a couple weeks ago: http://www.engadget.com/2007/07/19/the-lockdown-th e-medeco-m3-meets-the-perilous-paper-clip/ [engadget.com]

    Medeco offers several levels of key control to insure that its patent protected blanks cannot be copied, replicated or simulated. In many systems, proprietary keyways are available to further ensure that keys cannot be improperly compromised. Although the m3 is a very secure lock, we were able to simulate Medeco keys that can be made to bypass the keyway and slider protection of almost any system -- all without infringing on any Medeco intellectual property. It turns out that a standard paper clip will depress the slider precisely to the correct position. A wire or paper clip, fashioned as shown, is inserted into the keyway and wedged at the end of the body of the slider.
    So, with a proper paperclip, you can eliminate the additional security and remove its advantages against certain types of attacks.

    I remember buying a Samsonite briefcase with digital lock. Two weeks later I had a bunch of people try to open it over a weekend. Nobody managed to crack the 4 digit lock during the two days despite trying all available combinations and despite me opening it every time when I was handed it.

    Why?

    Because they DIDN'T try all available combinations. I discovered that the Samsonite digital lock with 4 positions from 0..9 can have a total of 11110 combinations instead of 10000 because you do not need to use all positions (which is not even in the little manual). In other words, the number of possible combinations is 10000 + 1000 + 100 + 10. The combination in use was "9" with me pretending to press the remaining 3 digits so there was a little bit of misdirection involved :-)

    Having said that, that specific lock has a more fundamental flaw that allows it to be easily reset, and this type of briefcase is not popular with airport security so I eventually stopped using it.

    Lockpicking is the oldest form of cracking, not hacking. Hacking is best summed up as "unconventional and creative use of technology". It is not a synonym for breaking and entering.

    The thin strip of metal is called a "key" - you insert it into the "lock", and turn it. I'm not sure of the screwdriver's purpose. Perhaps you use it to scratch your head, wondering why you brought it along.
