Kryptonite U-Lock Security Flaw
An anonymous reader writes "Once upon a time, a magic marker was able to defeat the Key2Audio copy protection scheme of older Sony CDs. Now, it has been shown that a Bic pen can easily open several models of Kryptonite U-locks. Please patch your systems, or install a tracking device on your bikes!"
sure this site will be /.ed soon....

From their home page:
"Canton, MA September 17, 2004 - Kryptonite today announced it will provide free product upgrades for certain locks purchased since September 2002, in response to consumer concerns about tubular cylinder lock technology. Consumers can visit the company's Website (www.kryptonitelock.com) on Wednesday afternoon, September 22, 2004, to learn how they can participate in the security upgrade program."

They probably figured that would be theives wouldn't know how to write anyway. I'm sure it was found ver secure against a crayon.

I tried it out with my own lock. 30 seconds and it was open. I called the Kryptonite company. At the time they were aware of the problem and are rushing their next generation of cylinders into production.
Interestingly enough, the problem was first reported in Britain in 1992. But it didn't go anywhere. Hurray for the age of fast information dissemination. And fast technology transfer to the bad guys.

... with a Garmin GPS receiver, and a Cell phone, I am looking for a bit of hardware to interconnect them so that if the bike takes off it will call me and I can report it's tracks to the local constabulatory.
Of course with my luck the thief will think the cell phone and GPS are a more attractive theft item than the Bke...

You never know...
at least one person won't be able to open this lock: Superman.
I used to be a bike messenger and I would have always told you, use a New York
Lock, which by the way, isn't vunerable to this attack. It's the best lock in
the world, but at $50, only bike messengers seem to care enough/or know enough
to pay the money. Honestly, I can't count the number of times I've seen
expensive 1K and up bikes locked up with a $20 lock. If that.

This is a flaw in the barrel style key system. I'm hardly a locksmith, but I've tried this on several of my locks and others just to prove the point, and the majority are not kryptonite locks. All of them have opened without more than 30 seconds of effort.
The sick part is the problem has been well known to manufacturers since 1992, and nothing has been done about it.

For less than the cost of a decent bike lock, you can buy a bike that's not worth stealing.

Tubular locks are usually designed so you have to turn it at least a quarter turn to open it, which would involve picking the lock several times. The Kryptonite they show releases the shackle in an intermediate position -- bad design there. A real tubular lock pick should open those locks; a simple plastic cylinder of the right diameter should not.

Kryptonite today announced it will provide free product upgrades
From what I have read, the upgrade will replace the lock core with one of a smaller diameter. This isn't really a long term fix - someone will probably discover a different brand of pen that will open the new locks as well.
I have tried the Bic pen on my own Krypto lock - and it's really easy. The strange thing is, this isn't some design flaw with the lock. Everyone (hopefully) knows that all locks can be picked. But, it should be hard, requiring specialized tools and some skill. The Bic pen seems to have just the right magical combination of size, and balance of hard/soft plastic, that it makes an astonishingly effective lock pick. After opening my lock, the pen barrel had divots in it from the pins that looked just like my key. The plastic seems hard enough to push the pins down until they set, but then soft enough to hold the pin in that position.
Also, this isn't exactly breaking news.
Quick! Sue BIC under the DMCA as a device that can defeat a security lock
The pins in the lock are vunlerable to being raked because they're all set in roughly the same position. If they were disparate, you couldn't successfully rake them (except if you were very lucky and could bite chunks out of your bic pen to match the right key :)
The solution to the problem, THAT is the issue. Let's gather around and think of what the big organizations/individuals would do to solve a problem such as this.
US goverment: Liberate bike from thief using a squadron of B2 bombers. At one point or another, several brits die, even if Rhumself has to find them and kill them himself. Bic pens linked to Al-Qaida.
Australian goverment: Send in Steve Irwin. If he gets killed, it's a good thing. If catches the thief, it's a better thing.
Brittish goverment: Sod the thief, fancy a scone, dear chap?
United Nations: Convene in an emergency session, go into recess after 10 minutes for cookies and tea. In the end, they condemn the theft but none of them manages to do fuck all.
European Union: The French and the Brits start bitching at eachother about which country has superior Bic pens. Germany and Spain wonder since when the damn Brits are part of Europe. The rest of Europe tried to talk tough before getting bitchslapped into submission by Germany and France.
RIAA: Claim that people who open locks use it to fund terrorism. Randomly sue locksmiths.
Microsoft: Vehemently deny existence of faulty locks. Release hotfix for existing locks, which consists of pouring glue in keyhole.
SCO: Sue Bic, 3M, Canada, a random seagull and the tooth fairy for copyright infringement on their proprietary way of opening locks with ballpoints.
Richard Stallman: Proudly proclaim the bike simply wanted to be free.
Eric S Raymond: Something irrelevant that contains a plug for "The Cathedral and the Bazaar".
Larry Wall: Make all locks so confusing that thieves don't know how to open them. Nor do the owners. Or manufacturers, for that matter.
George Lucas: Make a movie about bikes being stolen with Bic pens. Milk this movie out until 2050.
Bruce Willis: Get a bunch of oil drillers to find the thief and shove a nuke up his ass. And for the love of Eris, someone PLEASE screw Liv Tyler!
Pass a law declaring Bic pens to be "burglary tools", which can only be carried by "licensed professionals", and arrest anyone found in possession of one without a license. It works so well for lock pick kits...

"This is an extremely big deal. Kryptonite is the Microsoft of locks," said Brown, who estimates hundreds of thousands of the U-locks have been sold over the years. Kryptonite will not divulge sales numbers.
Well, they certainly are more like Microsoft now. Good for them

Kryptonite today announced it will provide free product upgrades for certain locks purchased since September 2002
What they don't mention is that the flaw was first documented in the trade publication "Bicycle Business" magazine in 1992. So they've been knowingly selling defective locks for 12 years since then hoping that this day would never come.
I've got five Krytonite locks:
Two KryptoLok ATB U-Locks, one of which was never taken out of the package.
One KryptoDisco-C motorcycle disc brake lock.
One 6' x 5/8" Kryptonite Flex Security cable lock.
One Kryptonie Flex Security U-Lock.
All of the locks are in very good to new condition and all of them are older than two years old. That means I get no replacement locks from Kryptonite nor do I get any upgrades. I hear tell that I might get coupons for rebates on new Kryptonite locks. But it will be a cold day in hell before I ever buy another Kryptonite product if they don't fix or replace the locks I have at no charge to me.
I am not being unreasonable. A lock, if well-cared for, is a lifetime investment. A well cared for lock that's five years old is no less useful than one which is 1 year old. Why should Kryptonite customers suffer because Kryptonite chose to knowinging, and deceptively, sell a defective product for over a decade? Anyone who bought a Krytonite lock with this flaw since the original article was published in 1992 should get a free upgrade/replacement.
I have a vending machine to try this on. It is a GIII Royal Vendors unit similar to all machines used by Coca Cola for about the past 10 years (though the faces have changed). First, The tumbler takes a 270 degree turn of the key to unlock. Every time you turn it past a set of pins, you'd have to re-pick the lock. To open this lock, you'd have to pick it proably upwards of 15 times -- Due to the design of the machine, it would be easier to physically pop or drill the cylinder itself. If you just want to steal the money out of it, you can just go through the lexan and use a crowbar to get at the coin changer and overflow box. Accessing the bill changer storage will require the lock to be removed.
Royal Vendors sells high security versions of these machines, though that put a large steel bar over the normal cylinder that can be locked with a padlock. They can also replace the lexan front with sheet steel and add plating around the front door to make it impossible to wedge a pry bar in there easily. My machine has the padlock bar and the side plating, but not the steel front.
Coke machines aren't really worth breaking into for the ~$100 or less that you could get out of them..
When stationed at Kunsan AB korea, circa 1993, the only transportation option open to enlisted people was a bicycle. You could buy one at the base BX for about $100 bucks. For an additional $4.oo dollars, you could buy a chain with a built in combination lock. The biggest problem with the entire system was this.......EVERYONE had the same model bike, and the same chain/lock. You could literally spend a half hour trying to find the bike and chain that belonged to you. This was quite a problem for some of us, untill we learned that with a bit of tension on the lock, and a bit of manual dexterity, you could open any of the locks in about 45 seconds. After that, we all adopted the idea that those of us that had purchased a bike, but couldnt find it anymore, could just go ahead and ride what ever bike was handy. After all, EVERYONE had the same bike and lock, so really...........all bikes were secretly the one you bought. Therefore, if you were able to pick the lock, you were entitled to ride the bike. This Utopia breaks down when you consider that in most cities, not everyone buys the same bike and lock. Therefore, it is incumbent on the government to provide everyone with a bike, thus insuring that there is no need for anyone to steal a bike. I will be putting this idea to my senator soon.....hopefully everyone will have a new bicycle in time for the novemeber elections
