Sports fans of locking technology
The Sportsfreunde der Sperrtechnik - Germany eV (short: SSDeV ) is a sports club that deals with the non-violent and non-destructive opening of all types of locks (" lockpicking "). The association was founded in 1997 by Steffen Wernéry, Arthur Bühl (Arthurmeister), Martina Falkenreck, Jürgen Dreeßen, Gunnar Franke, Niels Provs and Johannes Markmann in Hamburg and now has almost 1500 members in Germany, who are divided into 16 local groups (status: February 2008).
Goals and Activities
For lock picking , the club members use a wide variety of techniques and tools, all of which have in common that the lock remains undamaged during the opening process. The focus of the activities is the competitive opening of locks. The SSDeV has been organizing the German championships in lock opening every year since 1997. The association also offers workshops .
The association attaches great importance to the self-imposed code, which makes it clear that the activities may not be misused for criminal purposes. The top priority is that only your own locks may be opened or those with the explicit permission of the owner.
The association also expressly emphasizes that no instructions for break-ins are given. On the one hand, as part of their sporting activities, the members do not handle doors, but only with individual locks or lock cylinders (often clamped in vices ), and on the other hand, burglars do not even bother to learn how to open locks non-destructively (with a lot Experience and dexterity are required), but rather use force.
With their specialist knowledge, the members of the association also support police authorities in the forensic field, although no training for break-ins is given here either. For example, the association made profile cylinders available to the Berlin State Criminal Police Office , which members were able to overcome without being destroyed so that forensic investigations could be carried out. The association also helps to uncover weak points in the locking technology. In 2004 a member of the association discovered a serious security problem with the electronic lock "BlueChip" from Winkhaus . This lock opens with a plastic key, which digitally sends an encrypted code to a receiver built into the lock, which unlocks the lock. The lockpicker had found out that the lock can be unlocked with a sufficiently strong magnet (in this specific case a neodymium magnet with 80 kg pulling force) without a key or code. Winkhaus then stopped production of this model and has only been using BlueChip locks since 2005, which are secured against this type of attack with magnetic protection.
A similar exploit for an electronic lock from Uhlmann & Zacher was described at a lecture at the 11th German Championships in Lock Opening 2008 in Berlin. Here a technique was presented in which the lock could be opened with the help of a rotating magnetic disk without the otherwise necessary code. The manufacturer then released a firmware upgrade that eliminated this vulnerability.
