🛡️ Cloudflare has begun redacting and hiding domains tied to the rapidly growing Aisuru botnet after those malicious hostnames repeatedly appeared atop its public domain rankings. The botnet — comprised of hundreds of thousands of compromised IoT devices — recently shifted from querying 8.8.8.8 to 1.1.1.1, flooding Cloudflare’s resolver and skewing popularity metrics. Cloudflare says attackers are likely both manipulating rankings and mounting attacks on its DNS service, and the company is refining its ranking algorithm while removing known malicious entries.

🔒 ISO 15118-2-compliant EV charging implementations using the SLAC protocol are vulnerable to spoofed measurements that can enable man‑in‑the‑middle attacks between vehicles and chargers, tracked as CVE-2025-12357 (CVSS v4 7.2). The issue is an improper restriction of communication channel (CWE-923) and may be exploitable wirelessly at close range via electromagnetic induction. ISO recommends using TLS (required in ISO 15118-20) with certificate chaining; CISA advises minimizing network exposure, isolating control networks, and using secure remote access methods.

🤖 AWS announced an open-source AI agent context package for AWS IoT Greengrass that provides ready-to-use instructions, examples, and templates to accelerate edge device application development. The package is published on GitHub under the Creative Commons Attribution Share Alike 4.0 license and is designed to integrate with generative AI tools such as Amazon Q. Developers can clone the repository to jumpstart creation, testing, and fleet-wide deployment workflows across supported Regions.

🛡️ Aisuru, first identified in August 2024, has been retooled from launching record DDoS assaults to renting hundreds of thousands of compromised IoT devices as residential proxies. Researchers warn the change powers a massive proxy market that is being used to anonymize large-scale content scraping for AI training and other abuses. The botnet — roughly 700,000 devices strong — previously produced multi‑terabit attacks that disrupted ISPs and damaged router hardware. Industry and law enforcement are sharing blocklists and probing proxy reseller ecosystems tied to the infections.

🔒 The CloudEdge mobile app (v4.4.2) and associated online cameras contain a credential exposure flaw assigned CVE-2025-11757 that stems from improper MQTT topic handling (CWE-155). Unsanitized topic input allows an attacker to use MQTT wildcards to subscribe to other users' messages and extract credentials and key material, enabling remote access to live feeds and camera controls. CISA calculated a CVSS v4 base score of 8.7 and highlights low attack complexity and remote exploitability. Users are advised to minimize network exposure, isolate devices behind firewalls, employ secure remote access methods such as VPNs with caution, and contact Meari Technologies support at support@mearitek.com.

🛰️ Aisuru, now the world’s largest IoT botnet, is drawing the majority of its attack volume from compromised consumer devices hosted by U.S. ISPs such as AT&T, Comcast and Verizon. In early October the botnet briefly generated a near‑30 terabit-per-second traffic flood, underscoring its rapidly expanding scale and destructive reach. The attacks have targeted gaming-focused networks and protection providers, causing widespread collateral congestion and forcing providers to reassess outbound mitigation. Built on Mirai-derived code, Aisuru is also being marketed as a residential proxy service, complicating attribution and remediation.

🚗 Modern vehicles increasingly rely on interconnected electronics and external services, creating multiple remote attack vectors — from CAN, LIN and OBD ports to Wi‑Fi, Bluetooth and cellular links. The article notes that attackers now often target manufacturer servers (e.g., Toyota’s 2024 data loss) and references UN R155/R156 and ISO/SAE 21434. It describes vehicle risk categories, practical buyer and setup checks, and step‑by‑step advice if you suspect a compromise.

🔒 An authentication bypass vulnerability (CVE-2025-10538) affects LG Innotek camera models LND7210 and LNV7210R (all versions). CISA rates the issue as remotely exploitable with low attack complexity — CVSS v4 base score 8.8 — and warns an attacker could gain administrative access and access user account information. LG Innotek has classified these models as end-of-life and no patch is available; CISA recommends reducing network exposure, isolating devices behind firewalls, and using secure remote access methods such as VPNs while performing risk assessments.

🏙️ Smart cities are expanding rapidly—69% of municipalities report strategic agendas and an estimated 83,000 sensors were deployed in 2024—significantly enlarging the attack surface. High-profile incidents (Dallas alarm hack, Washington, DC ransomware, Florida water-treatment manipulation, and Olsztyn transport disruption) show that networked devices can lead to both digital and physical harm. Experts from Accenture, Zebra Technologies, and S2GRUPO warn that legacy devices, fragmented governance, and IT/OT convergence demand zero-trust, segmentation, and coordinated incident response to reduce systemic risk.

⚙️ 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.
