🇨🇳 Visión Estratégica de China: Fortaleciendo la Autosuficiencia y la Innovación

El Partido Comunista Chino (PCCh) ha delineado recientemente una estrategia integral centrada en un crecimiento económico autosuficiente y de alta calidad. Durante su última sesión plenaria, el PCCh enfatizó el control estatal, la innovación y el avance tecnológico como pilares del futuro de China. Bajo el liderazgo de Xi Jinping, China busca asegurar su posición como líder global en sectores clave como la IA, la computación cuántica y la energía limpia. Estos desarrollos marcan un giro hacia una mayor autosuficiencia, lo que podría desafiar las dinámicas económicas y políticas globales. La estrategia de China prioriza no solo el crecimiento económico, sino también la estabilidad social y la seguridad nacional. Los próximos cinco años serán cruciales mientras el país enfrenta una creciente competencia global y desafíos internos. El compromiso del PCCh con un modelo económico socialista refleja su intención de mantener el control sobre la dirección del país, rechazando la liberalización del mercado en favor de un enfoque más controlado y orientado a la innovación. Esta visión estratégica puede tener profundas implicaciones para las relaciones internacionales y el equilibrio de poder global. #China #EstrategiaEconómica #Innovación #Geopolítica #XiJinping #Tecnología #EconomíaGlobal paper interesante publicado en #IEEE por Xulio Rios

Your Windows Is No Longer Updated!

At BlackHat 2024, researchers unveiled an elegant attack called "Windows Downdate," which exploits a series of vulnerabilities and logical flaws in the Windows update system. The attack targets a poorly controlled phase of the update installation process, allowing attackers to modify the action list (Pending.xml) and use the HardlinkFile directive to install new system files.

Although these files must be signed, preventing the injection of malware, outdated and vulnerable files from Microsoft itself can still be installed.

Once these vulnerable files are in place, attackers can exploit long-known vulnerabilities to gain control of the system, potentially up to the hypervisor level. With some additional manipulations, real updates can be effectively blocked, while standard integrity-checking tools report that all components are up-to-date.

Microsoft has acknowledged the issue but has been unable to resolve it, despite investigating potential solutions since February. The company states that thorough testing is required because the fix affects too many components and files. The vulnerabilities have been assigned CVE-2024-21302 and CVE-2024-38202, but the security bulletin currently only provides general recommendations, such as minimizing user privileges related to backup functions and access to OS backup folders.

It’s worth noting that, according to the description of the attack, administrative privileges are required to carry it out. However, Microsoft's cautious wording suggests that there may also be escalation scenarios from non-privileged accounts.
