Sophos analysts are investigating a persistent, multi-stage malware distribution campaign targeting WhatsApp users in Brazil. First observed on September 24, 2025, the campaign (tracked as STAC3150) delivers archive attachments containing a downloader script that retrieves multiple second-stage payloads. In early October, Counter Threat Unit™ (CTU) researchers detailed activity associated with a separate Brazil-based campaign in which the threat actors leveraged WhatsApp to deploy the Maverick banking trojan for credential theft. In STAC3150, the second-stage payloads include a script that collects WhatsApp contact information and session data, and an installer that deploys the Astaroth (also known as Guildma) banking trojan (see…

In many cases, industrial composting has been required to break down biopolymers. Biodegradable plastics are emerging as an alternative to conventional plastics to address microplastic pollution. Unlike conventional plastics, biodegradable plastics are designed to break down over a faster timescale under specific conditions, potentially reducing long-term persistence in the environment. Although regulations are driving the market to adopt biodegradable alternatives, their role in tackling microplastic pollution can be contentious. Dr Shababa Selim, a senior technology analyst at market intelligence firm IDTechEx, explores whether biodegradable plastics can address microplastic pollution, previewing the findings of a new report.1 Biodegradability of biodegradable plastic…

SwiftIO is an electronic circuit board that runs Swift on the bare metal. It can control sensors, displays, lights, motors and more. The SwiftIO boardMadMachine’s SwiftIO board is an Arduino-like system, but it can run Swift code natively on the hardware. Swift is a great programming language for education purposes, it is a modern language with a JavaScript-like syntax that is easy to learn and understand. Swift is safe and efficient, this combination makes it a perfect candidate for embedded systems. The SwiftIO board enables us regular Swift / iOS developers to build IoT projects using our favorite programming language.The…

The Connectivity Standards Alliance (CSA) has released Zigbee 4 and Suzi to standardise secure, interoperable, and scalable IoT connectivity.Managing enterprise IoT has long been a balancing act: IT leaders want data visibility, but they often get stuck managing fragmented and congested networks. The CSA’s latest update, underpinned by the core R23 specification, targets these friction points by harmonising traditional device profiles with Smart Energy standards and formalising sub-GHz networking under a new brand identity.This release signals a maturation of wireless mesh networking. The focus has drifted away from novel consumer features toward the stability, range, and security architecture required for…

What exactly does word2vec learn, and how? Answering this question amounts to understanding representation learning in a minimal yet interesting language modeling task. Despite the fact that word2vec is a well-known precursor to modern language models, for many years, researchers lacked a quantitative and predictive theory describing its learning process. In our new paper, we finally provide such a theory. We prove that there are realistic, practical regimes in which the learning problem reduces to unweighted least-squares matrix factorization. We solve the gradient flow dynamics in closed form; the final learned representations are simply given by PCA. Learning dynamics of…

For many businesses, the promise of data-driven decision-making is out of reach – held back by manual processes across specialized tools and teams, and a shortage of technical expertise to manage them all. It’s time to finally focus on what matters most: using your data to drive better results, faster. That’s why we’re thrilled to announce new conversational AI and intelligent automation in the Precisely Data Integrity Suite: Gio AI Assistant is an AI assistant that makes data management conversational and accessible – removing barriers to data and enabling faster action A Data Catalog Agent that strengthens governance by automating the identification…
