"Ausgereifte" Hintertüren: Nvidia muss sich gegenüber Chinas Regierung erklären
Die Cyberspace Administration of China macht Nvidia schwere Vorwürfe. Die Firma muss beweisen, dass sie keine Hintertüren einsetzt.

So....let's talk 2nd season of #Pantheon and cyberspace fight scenes.
The show needed to depict AIs in a universe that shouldn't need to obey any laws of physics. Yet they chose to depict them as superheroes in an earth-like world. This already limits things.

Check out my latest CSO piece that examines how the Iranian cyber threat has been overhyped, and even in the face of a supposed cease-fire between Israel and Iran, security leaders need to stay alert and ready.
Many thanks to Tom Hegel of SentinelOne, Alexis Rapin of ESET, Pascal Geenens of Radware, Pete Nicoletti of Check Point and others for their insight.
Iranian cyber threats overhyped, but CISOs can’t afford to let down their guard

Iranian cyber threats overhyped, but CISOs can’t afford to let down their guard
Fears of Iranian retaliation in cyberspace surged after US and Israeli military strikes on Iran, but experts say the risk is overstated. Still, security leaders should stay alert and ready.

Game Theory Meets LLM and Agentic AI: Reimagining Cybersecurity for the Age of Intelligent Threats
Protecting cyberspace requires not only advanced tools but also a shift in how we reason about threats, trust, and autonomy. Traditional cybersecurity methods rely on manual responses and brittle heuristics. To build proactive and intelligent defense systems, we need integrated theoretical frameworks and software tools. Game theory provides a rigorous foundation for modeling adversarial behavior, designing strategic defenses, and enabling trust in autonomous systems. Meanwhile, software tools p…

Damn.
Most of the Bureau of Cyberspace and Digital Policy team that handles U.S. engagement with partner countries to prevent China from prevailing in AI and 5G wireless technologies, and in global data policy, were fired from the State Department.

Collaborative governance of cyber violence: A two-phase, multi-scenario four-party evolutionary game and SBI1I2R public opinion dissemination
Cyber violence severely disrupts public order in both cyberspace and the real world. Existing studies have gradually advocated collaborative governance but rely on macro-level theoretical analyses. This study integrates micro- and macro-level perspectives to propose a two-stage, multi-scenario governance mechanism for cyber violence. In the first phase, a multi-scenario evolutionary game model with four parties involved in cyber violence was developed based on evolutionary game theory. Matlab s…

Military AI Cyber Agents (MAICAs) Constitute a Global Threat to Critical Infrastructure
This paper argues that autonomous AI cyber-weapons - Military-AI Cyber Agents (MAICAs) - create a credible pathway to catastrophic risk. It sets out the technical feasibility of MAICAs, explains why geopolitics and the nature of cyberspace make MAICAs a catastrophic risk, and proposes political, defensive-AI and analogue-resilience measures to blunt the threat.

DTHA: A Digital Twin-Assisted Handover Authentication Scheme for 5G and Beyond
With the rapid development and extensive deployment of the fifth-generation wireless system (5G), it has achieved ubiquitous high-speed connectivity and improved overall communication performance. Additionally, as one of the promising technologies for integration beyond 5G, digital twin in cyberspace can interact with the core network, transmit essential information, and further enhance the wireless communication quality of the corresponding mobile device (MD). However, the utilization of milli…
