The author is examining Model Context Protocol (MCP) implementations by Anthropic, which standardize communication between AI models and external tools. While this protocol simplifies integration, it has significant security vulnerabilities. A major concern is that the natural language descriptions of tools, provided by MCP servers, are used directly by AIs to interpret commands. If an attacker controls the MCP server, they can manipulate these descriptions, tricking the AI into performing unintended actions, such as data exfiltration, without users being aware

An open letter addressed to Samsung expresses concern over the pre-installed AppCloud application on its A and M series smartphones in West Asia and North Africa (WANA). Users have reported that AppCloud, created by the Israeli-founded company ironSource, collects sensitive personal data without consent and cannot be removed without compromising device security. The letter calls for Samsung to provide transparency regarding AppCloud’s privacy practices, opt-out options, and to reconsider the pre-installation of such applications, especially in light of privacy rights amid

The introduction outlines a new series focused on Abstract Algebra, particularly Galois Fields (or Finite Fields), and their relevance to computer science. The author expresses frustration over the limited and often inaccessible resources available for computer scientists seeking to understand this topic, especially since Abstract Algebra isn't typically covered in computer science curriculums beyond the basics like Discrete Math and Linear Algebra. This series aims to bridge that gap by providing a detailed, step-by-step approach that includes practical code implementations. The author highlights the

In a blog post, Vincent D. Warmerdam shares his excitement about Mojo, a compiled language that can now be called from Python, which he sees as an opportunity for faster function execution. He notes that setting up Mojo has become simpler and demonstrates this with code examples for factorial and prime number counting functions. While he encounters some issues, like overflow when increasing the factorial number, he finds the performance promising when comparing it to a numpy implementation for prime counting. Although the modular stack is still in its

Klarrio has uncovered a significant malware network on GitHub, identified by CTO Bruno De Bus through his research. This investigation revealed that 2,400 repositories contain malware, supported by 15,000 fake accounts promoting these infected repositories with ratings. The discovery highlights an increase in cloned open-source GitHub repositories used to install malware on unsuspecting users. In response to rising concerns over malicious clones, Klarrio enhanced its open-source intake process to include stricter security measures, screenings, and automated

YouTube has been testing new anti-adblock measures, including a feature known as "fake buffering," where video loading times simulate buffering at the start of a video, mirroring the length of ads that would typically play. A user has developed a filter for uBlock Origin and Brave browser to partially bypass this fake buffering, which is included in default filter lists. The content also discusses YouTube's internal API, InnerTube, which the web client and mobile apps use to retrieve video data. GVS

In a recent meeting held in the Arctic Circle, mathematicians discussed new concepts of infinity, sparked by Juan Aguilera from the Vienna University of Technology. Despite the harsh winter environment, the group engaged in debates about the implications of these new infinities, which Aguilera believes could have significant consequences, although their nature remains unclear. Since the 1870s, when Georg Cantor demonstrated that different sets of infinity exist – such as the set of real numbers being larger than that of whole numbers – mathematic

Scientists have discovered a new dinosaur species, Khankhuuluu mongoliensis, in a Mongolian museum, which they believe alters the evolutionary timeline of tyrannosaurs, including T.rex. This species, identified from two 86 million-year-old skeletons, is the closest known ancestor of all tyrannosaurs and represents a transitional form between small, agile predators of the Jurassic period and the massive tyrannosaurs that later dominated. Weighing about 750 kg, Khankhuulu
