IoT Malware Protection Strategies

Your biggest cybersecurity threat might not be your employees — it might be your coffee machine. Everyone’s worried about employees clicking phishing emails… …but who’s worried about the smart thermostat leaking your sensitive data? (You should be.) When we talk about human cyber risk, it’s not just laptops and emails. It’s the people who plug in devices they don’t understand — or don’t think about — that open the backdoor. The truth is: The Internet of Things (IoT) is your weakest (and most ignored) security link. 📺 Smart TVs. 🏅 Fitness trackers. ☕ Coffee machines. 🔔 Video doorbells. 💡 Smart lighting. 🌡️ Even that “harmless” Wi-Fi-enabled fish tank thermometer in your lobby. (Yes, that actually happened to a casino in 2019 where the whole high roller database was exfiltrated through an IoT connected fish tank thermometer. Ouch.) If it connects to the internet, it can connect a threat actor to you. ACTIONABLE TAKEAWAYS: ✔️ Audit your IoT Devices: List everything in your business and home that’s internet-connected. If you don’t track it, you can’t protect it. ✔️ Segregate Networks: Keep IoT devices on a separate Wi-Fi network from business operations and sensitive information. ✔️ Change Default Credentials: Most IoT breaches happen because devices are left on factory settings. Change all passwords — immediately. ✔️ Update Firmware: Your smart devices need updates just like your computer does. Patch regularly or retire them if they’re no longer supported. ✔️ Train Your People: If they’re plugging it in, they’re opening a portal. Awareness matters. Train users to think before they connect. Bottom line: Human risk isn’t just about bad passwords and phishing clicks. It’s about our instinct to trust technology we don’t fully understand. If you employ humans, if you use IoT, you have risk. Manage your humans. Manage your tech. Or someone else will. #HumanRisk #Cybersecurity #IoTSecurity #InsiderThreat #CyberHygiene #Leadership #SecurityAwareness

Arm PSA Certified 2024 Security Report found that security is a rising team priority. To help you better comply with security regulations, here are a few recommendations from interviewing Memfault CEO François Baldassari: 1) Implement Secure OTA Updates Ensure that your IoT device supports secure over-the-air (OTA) updates with signed firmware. This is critical for addressing vulnerabilities and complying with regulations that mandate the ability to update devices remotely. 2) Encrypt All Communications Encrypt all data transmitted to and from the IoT device. This protects against unauthorized access and is a key requirement in both the Cyber Resilience Act (CRA) in the EU and the Cyber Trust Mark in the US. 3) Maintain a Software Bill of Materials (SBOM) Keep an up-to-date record of all software components and dependencies used in your device, including their versions and known vulnerabilities. Regularly check this against a vulnerability database to ensure any issues are promptly addressed. 4) Monitor and Track Device Behavior Implement observability in your IoT devices by monitoring network traffic, IP connections, and other key metrics. This helps in detecting anomalies that could indicate security breaches or vulnerabilities. 5) Engage with Security Best Practices and Standards Stay informed and align your practices with recognized security frameworks like PSA Certified from ARM. Engage with open-source communities and leverage security-focused tools and libraries to ensure your device meets regulatory requirements. Are you and your team ready for IoT Security Compliance?

Secure critical IoT/PT and ICS deployments with device and network security testing including breach and attack simulation - Securing critical infrastructure including ICS/OT and IIoT/IoT deployments requires solutions that emulates cyberattacks to protect connected devices and the networks of which they are connected. Safety, up-time/continuity and security, are critical for organizations operating large fleets of mission-critical connected devices, such as manufacturing, complex global and regional operations, healthcare and utilities. Yes, device manufacturers are responsible for security fixes, however these typically lag actual risks/attacks and zero days…enterprises need time to take vulnerable devices offline or replace them before they are compromised. Often these updates must be tested…and tested over time. Our personal experience is that some of these updates can be mission affecting with negative results. Therefore, testing networks and devices against multi-stage attacks — including ransomware infections, lateral movement, phishing attempts, protocol fuzzing, and data exfiltration — is vital. BLUF: To harden IIoT/IoT devices, use a device security test tool to subject them to low-level protocol fuzzing and upper-layer application attacks. Thoroughly test chipsets and network stacks to find flaws in Ethernet, Wi-Fi®, Bluetooth®, Bluetooth® Low Energy, LoRa, CAN bus, and cellular interfaces. Utilize specialized field and lab testing for OT devices that can ‘break’ if tested see our blogs on OT/ICS testing. At the same time, network security teams must continuously assess firewalls, endpoint security, and properly correlated SIEM/SOAR tools to prevent configuration drift and detect alerts. Use a breach and attack simulation(s) tool(s) to emulate multi-stage network attacks, reveal gaps in coverage, and identify remediations. Without these, security tool updates can inadvertently cause blind spots or vulnerabilities. Critical infrastructure and IIoT/IoT deployment security solutions require enterprises to secure critical OT/ICS/IIot/IoT deployments with both manual (RedTeam/PurpleTeam) and automated security testing and breach and attack simulation. These ideally should emulate multi-stage cyberattacks with your teams, scan for vulnerabilities, and mitigate risk with a systematic and  ever-expanding list of security assessments, audits, and test plans.
