Unlocked: PICing a wireless door access system
Mainframe, Oldenburg's Hackerspace, needed a wireless door lock solution. We do not trust vendors advertising promises about the device security and had a closer look.
Attend this talk for a presentation about an unusual variant of lock picking, which does not involve any wrenches, hooks or half-diamond picks. Instead the used tools are a software defined radio, PIC programmer and some self-developed software to gain access without using the original key remote control.
If you had fun watching the Hörmann BiSecur talk at 34C3, this talk is for you! If you haven't watched it, it is highly recommended to catch up on it before attending this talk. While it is about a different product from a different vendor, there are many parallels and it can be seen as a sequel talk.
The plan for this talk is to first have a look at the radio signals from the door lock using a SDR. After making sense of the used message protocol, the hardware is analyzed to understand how it works and how to get access to the used micro-controllers (PIC18LF45K80 & PIC16LF1829). In the next step, the firmware from the read-protected PIC microcontroller is extracted by extending the existing PIC attacks. Last but not least the results will be demonstrated.

Hardware hacking tooling for the new iPhone generation If you've followed the iPhone hacking scene you probably heard about cables such as the Kanzi Cable, Kong Cable, Bonobo Cable, and so on: Special cables that allow access to hardware debugging features on Lightning-based iPhones such as UART and JTAG. However with the iPhone 15, all of those tools became basically useless: USB-C is here, and with that we need new hardware and software tooling. This talk gives you a brief history of iPhone ...

Tesla's driving assistant has been subject to public scrutiny for good and bad: As accidents with its "full self-driving" (FSD) technology keep making headlines, the code and data behind the onboard Autopilot system are well-protected by the car manufacturer. In this talk, we demonstrate our voltage-glitching attack on Tesla Autopilot, enabling us root privileges on the system.

Imagine discovering a zero-click attack targeting Apple mobile devices of your colleagues and managing to capture all the stages of the attack. That’s exactly what happened to us! This led to the fixing of four zero-day vulnerabilities and discovering of a previously unknown and highly sophisticated spyware that had been around for years without anyone noticing. We call it Operation Triangulation. We've been teasing this story for almost six months, while thoroughly analyzing every stage of ...

Elektronische Arbeitsunfähigkeitsbescheinigungen (eAU), Arztbriefe, medizinische Diagnosen, all diese sensiblen Daten werden heute mittels KIM – Kommunikation im Gesundheitswesen – über die Telematikinfrastruktur (TI) verschickt. Aber ist der Dienst wirklich sicher? Wer kann die Nachrichten lesen, wo werden die E-Mails entschlüsselt und wie sicher ist die KIM-Software? Im Live-Setup einer Zahnarztpraxis haben wir Antworten auf diese Fragen gesucht.

This talk will present details of the TETRA:BURST vulnerablities - the result of the first public in-depth security analysis of TETRA (Terrestrial Trunked Radio): a European standard for trunked radio globally used by government agencies, police, military, and critical infrastructure relying on secret cryptographic algorithms which we reverse-engineered and published in August 2023. Adding to our initial disclosure, this talk will present new details on our deanonymization attack and provide ...

We present an analysis and recovery method for files encrypted by Black Basta, the "second most used ransomware in Germany". We analysed the behaviour of a ransomware encryptor and found that the malware uses their keystream wrongly, rendering the encryption vulnerable to a known-plaintext attack which allows for recovering affected files. We confirmed the finding by implementing tools for recovering encrypted files. We have made our tools for decrypting files without access to the actual key ...
