Hackerhotel 2024: Opening electronic safe locks with Ketchup and Lasers

woensdag, februari 21st, 2024

Hi all, I would like to share a presentation I’ve worked on for quite a while. The talks were on electronic safe locks, and a starting point for lockpickers to get into picking electronic locks. For Hackerhotel 2024 I’ve decided to create a summarized version to inspire others to pursuit electronic security research, and apply the knowledge on electronic locks.

The talk, linked below, has two main topics; Opening electronic locks with Ketchup, so-called liquid spiking, and attempts in reading the memory of the 8051 chip in the early Kaba-mas X0 locks. X07 to X09, specifically. When I find time, I’ll work both into a series of blog posts as well, but no promises.

If after this presentation you like an idea of other talks at Hackerhotel, there are some great ones. Walter presented about Lucid dreaming, and Chantal and Nancy discussed what man can do to promote diversity in the workspace. Women in tech, specifically.

Hackerhotel 2024: Safe cracking workshop

vrijdag, februari 16th, 2024

Hugo and I taught Safe cracking to a group of eleven at Hackerhotel 2024. It was great sharing the knowledge and inspiring others. Much respect goes to the attendees, which after a busy conference still had energy to take on this mighty challenge.

Every training needs to start with a good basis. We started with an introduction on what safe locks are about and how they operate, specifically group two safe combination locks. From there, we built knowledge from practical examples and exercises. From simply operating the safe lock by dialing 4L-3R-2L-1R with a known combination, to exploring contact points and graphing.

For this two-hour session, we worked with locks of known combination, and usually only get to complete one and a half graphs in this time. Around six graphs were completed in total, and some even finished all three graphs within the session.

While any training is mostly satisfying a curiosity, we expect this training gave the attendees enough knowledge to give it a try on their own later. Maybe even getting obsessed about it in the process 🙂

Challenge completed!

vrijdag, februari 2nd, 2024

Walter and Jan-Willem successfully completed the UKLS January challenge, and like to share the lessons learned as well as show off the 31 locks. The challenge is to open a lock, every day, for the days of January. This is a good way to get in the consistent lockpicking practice, and challenge yourself to pick more difficult locks. You can find a longer explanation of the challenge in the blog released earlier this year. (https://blackbag.lockcon.nl/?p=4023).

Picking a lock a day has helped me to get use to my new thick acrylic Moki handles, and taught me a few new picking tricks. As the month progressed, I attempted quite difficult locks, of which most didn’t open, at least not right away. For example, I’ve played an hour a day with a particular BKS, which still remains shut. When a lock didn’t open after a while, I frequently tried another lock, if not to keep the streak.

Walter picked a DOM, Pfaffenhain, Nemef, Mul-T-Lock, Wally, Anker, EVVA, ISEO, Gerda, CES, Ivana, Geba, Novoferm, Wilka, FF, Abus, Thirard, Yale, Vachette, Lips, Pratic, S2, Sobinco, Mauer, Corbin, BASI, VBH, Zeiss Ikon, Destil, Kale and an M&C.

On the other hand Jan-Willem picked the Kibb, Dom Sigma, Abus C83, MD, Anker, CAS, Gerda, Lockinox, Nemef, Pfaffenhain, Kraft, Nino, Gaba, (another) Lockinox, Bern, Yale, Axa, S, Era, UAP, Evva, M&C, F (can’t recall, federico? fred?), Iseo, Fake Assa 700, (2nd) gaba, corbin, mila, Ivana, Favour, and a SEZAM cylinder.
