⚙️ AWS published a Model Context Protocol (MCP) server for AWS IoT SiteWise in the AWS Labs open-source MCP repository to simplify industrial data modeling. The server embeds domain validation and automated modeling, applying correct units, data types, and quality indicators so models are production-ready. It maintains compatibility with existing SiteWise tools and APIs while adding conversational interfaces to streamline model authoring, asset onboarding, and downstream analytics enablement.

🔷 Microsoft was named a Leader in the 2025 Gartner Magic Quadrant for Global Industrial IIoT Platforms, highlighting its industrial cloud portfolio. Azure’s adaptive cloud—anchored by Azure IoT, Azure Arc, Azure Digital Twins, and Microsoft Fabric—is positioned to unify cloud-to-edge data, enable real‑time intelligence, and scale AI-driven operations. The platform emphasizes security with Microsoft Defender for IoT, Microsoft Sentinel, and Microsoft Entra, while enabling brownfield integration and partner-led solutions to accelerate industrial modernization.

🔧 AWS IoT ExpressLink technical specification v1.3 introduces expanded Bluetooth Low Energy (BLE) capabilities and a new set of I/O control commands that enable host processors to manage module pins. The BLE enhancements make it easier for devices to advertise presence and capabilities and to pair securely within a local Personal Area Network (PAN). The I/O control commands allow an ExpressLink-powered module to act as a flexible digital and analog I/O expander. AWS Partners including Espressif and u‑blox have adopted the update for their Wi‑Fi and BLE qualified modules.

🔍 A research team at SUTD's ASSET group released Sni5Gect, an open-source over-the-air toolkit that passively sniffs early 5G signaling and injects crafted payloads before NAS security is established. The framework can crash UE modems, fingerprint devices, bypass some authentication flows, and force downgrades from 5G to 4G without deploying a rogue gNB, with reported injection success rates of 70–90% at up to 20 m. GSMA recorded the issue as CVD-2024-0096.

🛡️ FortiGuard Labs reports the resurgence of a Mirai-derived IoT malware family, publicly known as “Gayfemboy,” which reappeared in July 2025 targeting vulnerabilities in DrayTek, TP-Link, Raisecom, and Cisco devices. The campaign delivers UPX-packed payloads via predictable downloader scripts named for product families and uses a modified UPX header and architecture-specific filenames to evade detection. At runtime the malware enumerates processes, kills competitors, implements DDoS and backdoor modules, and resolves C2 domains through public DNS resolvers to bypass local filtering. FortiGuard provides AV detections, IPS signatures, and web-filtering blocks; organizations should patch and apply network defenses immediately.

🔒 Researchers have identified a chain of four Bluetooth vulnerabilities collectively named PerfektBlue in the OpenSynergy Blue SDK, used in millions of vehicles. An attacker that pairs via Bluetooth can exploit AVRCP flaws to execute code on the head unit and inherit its Bluetooth privileges, potentially accessing microphones, location data, and personal information. Vehicle owners should update head-unit firmware when patches are available and disable Bluetooth when not in use.

📅 In episode 430 of Smashing Security, host Graham Cluley and guest Dave Bittner examine a range of security stories, led by a proof‑of‑concept attack that weaponises Google Calendar invites to trigger smart‑home actions. They also cover a disturbing incident where ChatGPT gave dangerous advice that led to hospitalization and discuss the new Superman trailer. The episode blends technical detail with accessible commentary and practical warnings for listeners.
