When locksmiths go bad. Black hat lockpicking has been around forever but it is very rarely spoken about. It is the elephant in the lockpicking room. Using some real-life examples, the murky world of the black hat locksmith is explored. As this talk will be in Finland, it is fitting that I have found myself specialising in Abloy over the last 8 years or so (purely because nobody else had (seemingly) done so). Starting with the 110 year-old Abloy Classic, I have worked my way up the Abloy food chain and now make tools to do open the whole family. Abloy have a mythical status as unpickable locks, so it might be a shock to the average Fin that this is even possible. I will show some weaknesses in Abloy locks and how Abloy have fixed them over the years and why picking Abloy is so difficult. Matt Smith started out as a Software dev (in COBOL no less) and then worked as a SCADA Systems Engineer. His love of subverting security covers his whole life and has taken him from social engineering, to hacking digital systems to hacking physical systems. His locksmithing career started as a black hat, with a taste for vending machines (and not the candy). This morphed into locksmith work, and now he makes bespoke locktools to open very specific, high security locks. When not toolmaking he enjoys finding physical 0-days, especially in Abloy. Any system has its holes, no matter physical, digital, social...you just have to find them and leverage them. He has a Bsc (Hons) Comp Sc from Staffordshire University and has demonstrated the opening of several locks that were previously thought impossible to open without force. Ask him about locks/tools!
