China on Monday released its third report on the “Volt Typhoon” investigation. The report not only provides critical new information but also delivers a clearer message to responsible stakeholders concerned with global cyberspace security and governance: A previously underappreciated threat must be taken seriously. This threat originates from US intelligence agencies and security bodies, which, possessing superior technological capabilities, engage in “false flag” operations — activities carried out to deliberately conceal the true origin of cyberattacks while falsely attributing responsibility to someone else, particularly an opponent. To serve their own interests, these organizations openly or tacitly collaborate with high-tech companies.

The Marble Framework mentioned in the latest investigative report was first exposed in 2017 when WikiLeaks claimed to have obtained information from inside the CIA’s Center for Cyber Intelligence. Developed by the CIA as an anti-forensics tool, the primary function of the Marble Framework is to obscure and disguise the true origins of cyberattacks, making it difficult to trace these attacks back to the actual perpetrators. The Marble Framework employs string obfuscation to hide textual information within the malware, as this text often provides forensic experts with clues to identify the developer or country of origin behind the malicious software.

A new all-optical switch uses circularly polarized light and an innovative semiconductor to process data faster and more efficiently in fiber-optic systems.

This technology facilitates significant energy savings and introduces a method to control quantum properties in materials, promising major advancements in optical computing and fundamental science.

Modern high-speed internet relies on light to transmit large amounts of data quickly and reliably through fiber-optic cables. However, when data needs to be processed, the light signals face a bottleneck. They must first be converted into electrical signals for processing before they can continue being transmitted.

Oh my. And here I was about to get Starlink.

Starlink has suspended new subscriptions in Nairobi and neighbouring Kiambu, Machakos, Narok, Murang’a and Nakuru regions, citing a network capacity overload due to increased demand.

WASHINGTON — The Australian Department of Defence announced the cancellation of its JP9102 military satellite program, an estimated $5 billion project awarded to Lockheed Martin just 18 months ago, citing shifts in satellite technology and the market’s pivot toward multi-orbit space communications.

The cancellation of Australia’s JP9102 satellite program is yet another sign of the disruptive impact that low Earth orbit space internet services, led by the rapid growth of SpaceX’s Starlink, are having on the traditional satellite communications industry and government procurement models.

JP9102, or Defence Joint Project 9,102, was launched in 2021 with plans to develop between three to five geostationary satellites and ground systems, marking one of Australia’s most ambitious space infrastructure ventures.

A team including researchers from Seoul National University College of Engineering has developed neuromorphic hardware capable of performing artificial intelligence (AI) computations with ultra-low power consumption. The research, published in the journal Nature Nanotechnology, addresses fundamental issues in existing intelligent semiconductor materials and devices while demonstrating potential for array-level technology.

Currently, vast amounts of power are consumed in parallel computing for processing big data in various fields such as the Internet of Things (IoT), user data analytics, generative AI, large language models (LLM), and autonomous driving. However, the conventional silicon-based CMOS semiconductor computing used for parallel computation faces problems such as high energy consumption, slower memory and processor speeds, and the physical limitations of high-density processes. This results in energy and carbon emission issues, despite AI’s positive contributions to daily life.

To address these challenges, it’s necessary to overcome the limitations of digital-based Von Neumann architecture computing. As such, the development of next-generation intelligent semiconductor-based neuromorphic hardware that mimics the working principles of the human brain has emerged as a critical task.
