A 50-year-old lock design was rendered useless last week when a brief post to an internet forum revealed the lock can be popped open with a cheap plastic pen.
On Sunday, bike enthusiast and network security consultant Chris Brennan described opening an expensive Kryptonite bike lock using a ballpoint pen.
Wired: Twist a Pen, Open a Lock
Much to our surprise, we were able to hack our Kryptonite Evolution 2000 U- Lock with a ballpoint pen. This $50 lock is supposed to be one of the best for “toughest bicycle security in moderate to high crime areas”—unless the thief happens to have a Bic pen. We used to use these to lock up our bicycles, but we’re switching to something else ASAP. (Oh, and just to be trite, the pen is mightier than the lock.)
