Contextal Platform: Open-source threat detection and intelligence

Contextal Platform is an open-source cybersecurity solution for contextual threat detection and intelligence. Developed by the original authors of ClamAV, it offers advanced features such as contextual threat analysis, custom detection scenarios through the ContexQL language, and AI-powered data processing—all operating locally to ensure data privacy. “We created Contextal Platform to address the stagnation in the cybersecurity market for advanced threat detection tools, particularly in the open-source domain. Existing solutions are often based on outdated … More → The post Contextal Platform: Open-source threat detection and intelligence appeared first on Help Net Security.

Using cognitive diversity for stronger, smarter cyber defense

In this Help Net Security interview, Mel Morris, CEO of Corpora.ai, discusses how cognitive biases affect decision-making during cybersecurity incidents. Morris shares insights on the challenges of designing user-friendly cybersecurity tools that consider human cognitive processes. How do cognitive biases impact decision-making in cybersecurity incidents? Cognitive biases significantly influence decision-making during cybersecurity incidents by framing how individuals interpret information, assess risks, and respond to threats. Common biases, like favoring information that aligns with our assumptions … More → The post Using cognitive diversity for stronger, smarter cyber defense appeared first on Help Net Security.

Cybersecurity is stepping into a new era of complexity

Cybersecurity is entering a new era of complexity, according to the World Economic Forum’s Global Cybersecurity Outlook 2025 report. Growing complexity intensifies cyber inequity This complexity arises from the rapid growth of emerging technologies, prevailing geopolitical uncertainty, the evolution of threats, regulatory challenges, vulnerabilities in supply chain interdependencies and the growing cyber skills gap. Growing complexity further intensifies cyber inequity, deepening the divide between developed and emerging economies, expanding sectoral disparities, and widening the gap … More → The post Cybersecurity is stepping into a new era of complexity appeared first on Help Net Security.

Researchers invent soft, bioelectronic sensor implant

Scientists describe their construction of complementary, internal, ion-gated, organic electrochemical transistors that are more amenable chemically, biologically and electronically to living tissues than rigid, silicon-based technologies. The medical device based on these transistors can function in sensitive parts of the body and conform to organ structures even as they grow. The result is a biocompatible sensor that can monitor brain functions in pediatric patients as they develop and grow.

New training technique for highly efficient AI methods

AI applications like ChatGPT are based on artificial neural networks that, in many respects, imitate the nerve cells in our brains. They are trained with vast quantities of data on high-performance computers, gobbling up massive amounts of energy in the process. Spiking neurons, which are much less energy-intensive, could be one solution to this problem. In the past, however, the normal techniques used to train them only worked with significant limitations. A recent study has now presented a possible new answer to this dilemma, potentially paving the way for new AI methods that are much more energy-efficient.
