Asahi Linux - Porting Linux to Apple Silicon (en)

sven

In this talk, you will learn how Apple Silicon hardware differs from regular laptops or desktops. We'll cover how we reverse engineered the hardware without staring at disassembly but by using a thin hypervisor that traces all MMIO access and then wrote Linux drivers. We'll also talk about how upstreaming to the Linux kernel works and how we've significantly decreased our downstream patches in the past year. As an example, we will use support for the Type-C ports and go into details why these are so complex and required changes across multi subsystems. In the end, we'll briefly talk about M3/M4/M5 and what challenges we will have to overcome to get these supported.

Security of Cardiac Implantable Electronic Devices (en)

dilucide

Cardiac Implantable Electronic Devices (CIED), such as cardiac pacemakers and defibrillators, are a fairly niche target for security researchers, in part due to a lack of manufacturer cooperation and device accessibility. This talk aims to provide insights into the challenges in device development and methods with which to research device security. Data accessibility to patients will be touched upon.

“End Of 10”: How the FOSS Community is Combatting Software-Driven Resource and Energy Consumption (en)

Joseph P. De Veaugh-Geiss, Carolina Silva Rode, Bettina Louis

The end of free support for Windows 10 was 14 October 2025. Well, sort of. Microsoft moved the date to 2026, one more year the FOSS community can introduce users to sustainable software. 14 October is also KDE's birthday, International E-Waste Day, with International Repair Day following on 18 October. The irony is deep, but what is not ironic is that millions of functioning computers will end up becoming security risks or discarded as e-waste. This means manufacturing and transporting new ones, the biggest waste of all: hardware production accounts for over 75% of a device's CO2 emissions over its lifespan. The FOSS community had an opportunity and we took it! In 2024, KDE Eco's Opt Green project began a global, unified campaign across FOSS and repair communities to upgrade unsupported Windows 10 computers to Linux. We held BoFs at SFSCon, CCC, and FOSDEM. We thought big and acted boldly. In this talk End Of 10 contributors will discuss the campaign, what has worked and what the challenges have been, and how FOSS provides a solution to software-driven resource and energy consumption.

Laser Beams & Light Streams: Letting Hackers Go Pew Pew, Building Affordable Light-Based Hardware Security Tooling (en)

Patch, Sam. Beaumont (PANTH13R)

Stored memory in hardware has had a long history of being influenced by light, by design. For instance, as memory is represented by the series of transistors, and their physical state represents 1's and 0's, original EPROM memory could be erased via the utilization of UV light, in preparation for flashing new memory. Naturally, whilst useful, this has proven to be an avenue of opportunity to be leveraged by attackers, allowing them to selectively influence memory via a host of optical/light-based techniques. As chips became more advanced, the usage of opaque resin was used as a "temporary" measure to combat this flaw, by coating chips in a material that would reflect UV. Present day opinions are that laser (or light) based hardware attacks, are something that only nation state actors are capable of doing Currently, sophisticated hardware labs use expensive, high frequency IR beams to penetrate the resin. This project demonstrates that with a limited budget and hacker-and-maker mentality and by leveraging more inexpensive technology alternatives, we implement a tool that does laser fault injection, can detect hardware malware, detect supply chain chip replacements, and delve into the realm of laser logic state imaging.
