Automating incident response: scalable & fast, within minutes (hackerhotel2025)
In today's rapidly evolving digital landscape, the increasing frequency and the scale of security incidents pose significant challenges for incident response teams. The traditional approach, rooted in digital forensics, is no longer sufficient nor is it efficient enough. It's time for a shift towards an automated incident response strategy that combines the investigative prowess of a digital detective with a DevOps mindset. In this talk, we will present how the incident response process of acquiring data, processing data, and analyzing information can be automated. Based on how we have built our incident response...
Getting a feel for lockpicking (opening up the world of locksport for the visual impaired) (hackerhotel2025)
Lockpicking is a sport where you open locks without force and mostly without keys. While doing this activity nothing much can be seen of the actual process. In stead you need to rely on sound and feel (tactile feedback from the lock). Therefor a lot of people (including us) think a visual impaired person could be rather good at this (as they are more trained to use the "other" senses) The firsts steps into locksport however are VERY visually heavy (video's, pictures, diagrams) which makes it rather hard for a visual impaired person to get...
De validatiecrisis (hackerhotel2025)
De opkomst van geavanceerde technologie en kunstmatige intelligentie heeft ongekende mogelijkheden gecreëerd, maar ook een sluimerend probleem blootgelegd: de validatiecrisis. In deze lezing neemt Brenno de Winter, gerenommeerd cybersecurity-expert en auteur van De Validatiecrisis, u mee in de wereld van misleidende aannames, ongeteste technologie, en de gevaren van een gebrek aan kritische evaluatie. Hij toont aan hoe deze crisis niet alleen technologie, maar ook maatschappelijke besluitvorming ondermijnt. Een belangrijk deel van de lezing is gewijd aan de MIAUW-methodiek (Methodiek voor Informatiebeveiligingsonderzoek met Auditwaarde). Dit gestructureerde framework biedt een oplossing voor de validatiecrisis in informatiebeveiliging door...

Nerding out over silly machines (hackerhotel2025)
You've maybee seen the raking robot that got a CEH (Certified Estetisch Harker) certificate, the Telex linked to Twitter/Telegram or the ASCII foto booth. They are all made by me. If this talk gets accepted I will do a deep dive on these three contraptions and what I learned building them. Beside Schuberg Philis, DIVD, attending the farm and keeping my bees I als build machines. It is an interesting process and I want to share it with you. Machiens I will be talking about: * The (worlds?) 1st 3d color printer from TNO * The raking robot * AI/Twitter/Telegram/Slack...

Биперная музыка на Arduino
Любимый отечественными энтузиастами компьютерной ретро-техники компьютер «Синклер» ZX Spectrum родом из начала 1980-х годов — восьмибитный. Любимый самодельщиками нынешнего тысячелетия Arduino родом из середины 2000-х годов — тоже восьмибитный. Они похожи, но такие разные. Сегодня попробуем навести мостик между этими мирами, преодолеть пропасть в два десятка лет, и заставить два разных устройства проиграть одни и те же мелодии.
В этой статье сплетаются сразу три темы: как устроены некоторые музыкальные полифонические процедуры на ZX Spectrum, как воспроизвести результат их работы в совершенно иной реализации на Arduino, а заодно немного электроники для начинающих — рассуждения на тему, как можно правильно или неправильно подключить...
