Microsoft’s agentic security system found four critical Windows RCE flaws

Help Net Security

Microsoft's new agentic security system has identified 16 vulnerabilities in the Windows networking and authentication stack, including four critical remote code execution (RCE) flaws. Among these, CVE-2026-40361 and CVE-2026-40364 are particularly concerning due to their higher likelihood of being exploited by attackers. These vulnerabilities could allow unauthorized users to execute arbitrary code on affected systems, potentially leading to severe security breaches. Organizations using Microsoft Windows should prioritize addressing these vulnerabilities to protect their systems from potential exploitation, especially as the threat landscape evolves. The discovery of these flaws underscores the importance of continuous security assessments in software development and deployment.

Researchers open-source a Wi-Fi cyber range for security training

Help Net Security

Researchers from the Norwegian University of Science and Technology and the University of the Aegean have developed a new open-source Wi-Fi cyber range designed specifically for security training. Unlike typical training programs that treat Wi-Fi as just another component alongside other wireless technologies, this new resource focuses solely on the IEEE 802.11 standard, which is crucial as Wi-Fi is often the primary entry point for cyber attackers targeting corporate networks. This initiative addresses a significant gap in hands-on training environments, providing a dedicated platform for professionals to enhance their skills in defending against Wi-Fi related security threats. By making this tool freely available, the researchers aim to improve the overall security posture of organizations that rely heavily on wireless networks.

Canvas Hackers ShinyHunters Say Their Official Domain Was Suspended

Hackread – Cybersecurity News, Data Breaches, AI and More

The hacking group ShinyHunters has reported that their domain, shinyhunte.rs, was suspended following a series of attacks on the Canvas Learning Management System (LMS). As a result, they have moved their operations entirely to their dark web site, which uses the .onion domain. This shift highlights the ongoing challenges in combating cybercriminal activities, especially those targeting educational platforms. The suspension of their domain could hinder their ability to communicate and distribute stolen data, but it also indicates the persistent nature of such groups in adapting to law enforcement actions. Users of Canvas and other educational institutions should remain vigilant as these incidents can impact the security of sensitive student information.
