Locks restrict access to anyone lacking the correct key. As security components, we depend on locks to secure our most valuable possessions. Most attacks demonstrated in recent years involve manipulation of the lock components with special picking tools, but what if we focused on using incorrect or blank keys to make a variety of tools? Bumping is a good example, but there are many other ways incorrect or modified keys can be used to defeat locks. Like the cryptography world, physical Keys are vulnerable to attack in even the highest security locks.
This talk focuses on using modified keys and key blanks to open, decode, and bypass several locking mechanisms, including many high security locks. We demonstrate and discuss the security implications of key-based attacks on modern lock designs.
