"Chinese scientists have developed the best shortest-path algorithm in XX years A team from Tsinghua University has broken Dijkstras sorting barrier the first improvement since 1984. The new algorithm runs in O(m log2/3 n) time. Potential applications Faster shorter waits for route calculations fewer traffic jams cheaper deliveries and more efficient computer networks. And of course a need to update computer science curricula :)"

"Chinese authorities allege a 27-month NSA operation against the China's National Time Service Center. Initial credential theft apparently via a smartphone-messaging exploit. They relese technical details including information about 80+ remote logins between April XX and August X 2023 to map the network followed by deployment of a framework and two documented exfiltration runs The stated objective is long-term espionage and pre-positioning inside Chinas national timing infrastructure explicitly moving toward the high-precision terrestrial timing/navigation system. The targets mission"

"In July 2025 the U.S. National Nuclear Security Administration (NNSA) and its Kansas City National Security Campus which produces most of the components for Americas nuclear weapons fell victim to a cyberattack. The attackers exploited vulnerabilities in Microsoft SharePoint (CVE-2025-49704 and CVE-2025-49706) which allowed them to bypass authentication and remotely execute code through specially crafted web requests. The attack may have been carried out by Chinese state-sponsored groups: Linen Typhoon Violet Typhoon and Storm-2603. In the case of the Kansas City facility there is also"

"Hackers start using AI infrastructure to steal data. A malicious Model Context Protocol (AI server) downloaded 1500 times weekly had a single line of code in a new version that secretly stolen every email. MCP servers operate with huge permissions autonomously used by AI assistants hundreds of times daily without any security review creating a massive blind spot in enterprises. Nice way to bypass traditional security systems. Expect a few medium-to-huge apocalypses at several places at some point"

"SOUTH KOREA GOVERNMENT CONFIRMATION OF MAJOR CYBERATTACK. South Korea's National Intelligence Service (NIS) and Ministry of the Interior and Safety officially confirmed a systematic breach of government systems lasting from September 2022 to July 2025. Yes three years of unauthorized access to the nation's administrative backbone. Hackers compromised six GPKI (Government Public Key Infrastructure) certificates and passwords through malware infections on government employees' personal computers used for remote work.

"Whoa. According to a Polish judge IF and this case was not about proving that Ukraine organized an armed mission to destroy enemy pipelines these actions were not unlawful. On the contrary they were justified rational and fair. Its worth noting that todays hearing was not about determining whether Volodymyr Zuravlov actually blew up the pipelines. He will not be handed over to Germany. Oh German prosecutors presented no real evidence just a single A4 sheet filled with vague claims"

"These materials represent a particularly sinister choice for sabotage operations. Thermite burns at 2500C and cannot be extinguished with water or conventional fire suppressants making it capable of melting through metal concrete and aircraft fuselages. Barium nitrate serves as an oxidizer that intensifies combustion and allows fires to burn even in oxygen-poor environments. Together in a remotely-detonated package traveling through courier networks or cargo planes they could trigger catastrophic fires mid-transport potentially causing aircraft disasters or warehouse infernos with significant"
