By DNSystems LLC (dnsystemsllc.com) The Cyber Resilience Act (CRA) will soon reshape how embedded device manufacturers approach security. Embedded systems, IoT devices, and hardware products must comply with strict requirements that cover everything from risk assessment to incident reporting.The CRA will change how manufacturers selling into the EU manage device security. With full applicability on 11 December 2027, EU-based makers and any vendors placing products on the Euro

By DNSystems LLC (dnsystemsllc.com) Artificial intelligence is changing how connected products work. It also changes how attackers find and exploit weaknesses. AI increases the attack surface for embedded systems, IoT devices, and hardware. This means more ways for bad actors to cause harm or steal data. At DNSystems, we focus on hardware security, embedded systems, IoT device protection, and penetration testing. We help organizations find and fix vulnerabilities before attac

By DNSystems LLC (dnsystemsllc.com) Introduction I reviewed a public write-up describing tooling intended to process and decrypt shared e‑scooter firmware. I also validated, at a high level, that firmware artifacts may be obtainable through legitimate distribution paths (for example, device-side update mechanisms or vendor-managed delivery infrastructure). This post summarizes risk-relevant observations and vendor recommendations while intentionally omitting exploit-level det

By DNSystems LLC (dnsystemsllc.com) Intro Modern devices, ranging from servers to IoT sensors, operate on firmware that, if compromised, allows attackers to maintain a presence below the OS. NIST SP 800-193 outlines practical resiliency: Protect, detect, recover. DNSystems LLC transforms that guidance into ............................. Quick,actionable services to ensure your fleet remains trustworthy and repairable. Why it matters Firmware lives below traditional defenses a

By DNSystems LLC (dnsystemsllc.com) The Internet of Things (IoT) continues to expand rapidly, connecting billions of devices worldwide. This growth brings convenience and innovation but also creates a vast attack surface for cyber-criminals. In 2026, attackers are no longer focusing on discovering entirely new bugs. Instead, they exploit scale, automation, and supply chain weaknesses to compromise IoT ecosystems. Understanding these trends is essential for security teams to p

By DNSystems LLC (dnsystemsllc.com) Public safety increasingly depends on connected devices and Internet of Things (IoT) technologies. These tools help responders gather real-time data, coordinate actions, and manage emergencies more effectively. Yet, the growing reliance on hardware and IoT systems also introduces new security risks. Vulnerabilities in devices or networks can lead to false data, hijacked commands, or system failures that endanger lives and missions. Strength

By DNSystems LLC (dnsystemsllc.com) The Internet of Things (IoT) has transformed how organizations operate. Embedded systems and connected devices now control critical functions across industries. This connectivity introduces new security risks. A comprehensive IoT penetration test is essential to identify vulnerabilities before attackers exploit them. Booking such a test online streamlines the process and ensures timely, expert assessment. Understanding IoT Penetration Test
