Ray is an independent security researcher from Germany. He is active member of the European hacker organization CCC as well as of the world's oldest lock-picking club SSDeV. He created the first 3D printed key in 2009 and replicated high security handcuff keys with a laser cutter. His practical lock picking skills earned him a DEFCON Black Badge before moving to analyzing and breaking electronic locking systems. In 2016 he was the first to break a BTLE lock which actually uses real encryption, showing that "AES128 encrypted" doesn't mean anything without looking at the whole system.
