Who runs the www? WSIS+20 and the future of Internet governance (en)

Sophia Longwe

Abbreviations such as WSIS+20, IGF, IETF, DIEM, ICANN, PDP, ITU or W3C regularly appear in discussions about the Internet, yet often remain vague. This talk provides an update on the current state of Internet governance and explains why decisions made in United Nations processes have direct implications for technical standards, digital infrastructure, and power asymmetries.
Von Groschen und SpurLos - GNU Taler auch auf eurem Event! (de)

Mikolai Gütschow, signum

Willkommen in der Zukunft: Beim LUG Camp in Wipperfürth und bei den Datenspuren in Dresden wurde digital bezahlt - mit GNU Taler als Event-Bezahlsystem. Noch einfacher als Bargeld, billiger als Kartenzahlung und ohne Eingriff in die Privatsphäre der Besucher*innen. Wir zeigen euch, wie auch ihr das bei eurer nächsten (Chaos-)Veranstaltung anbieten könnt!

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.
Battling Obsolescence – Keeping an 80s laser tag system alive (en)

Trikkitt

Keeping old projects working can be an uphill battle. This talk explores how the laser tag system Q-Zar (Quasar in the UK) has been kept alive since the company behind it failed in the 90s. The challenges encountered, the lessons learnt, and how those can be applied to our own future projects to maximise the project lifetime.
