400% Growth in IoT Malware Attacks

IoT (Internet of Things) and OT (Operational Technology) have transformed how IT teams interact with devices via the Internet. While offering efficiency, insights, and customer experience benefits for organizations, the devices are at significant risk because they lack built-in security measures, thereby making it easier for hackers to exploit their vulnerabilities.


Recently, Zscaler’s ThreatLabz team identified a 400% growth in IoT malware attacks, suggesting organizations still have some work left to do in combating future attacks with appropriate security measures. 


The ThreatLabz 2023 Enterprise IoT and OT Threat Report explores IoT/OT device traffic and malware targeting these devices and offers security best practices for preventing these attacks. It puts the convergence of IoT and OT driven by digital transformation in the spotlight to raise awareness for endangered sectors such as manufacturing and utilities to take action.


The manufacturing sector saw the most substantial surge in malware attacks- more than three times the attacks as any other sector. This surge in adoption underscores the industry’s dedication to embracing advanced automation and digitization, positioning it as a frontrunner in leveraging IoT/OT for enhanced production efficiency, product quality, and innovation.


However, the education sector had the sharpest increase in malware attacks, increasing nearly 1000%. Educational institutions are considered ‘soft targets’ because of the wealth of personal data stored on their networks, leaving both students and educational institutions vulnerable.


Provide a more effective and robust way to protect against cyber threats by assuming that no devices can be trusted and restricting unfettered access to the network. 


Zero trust is grounded on this exact premise — no device, user, or workload is inherently trustworthy, whether they are inside or outside the corporate network. Its architecture is key to preventing unplanned downtime and ensuring maximum productivity in OT industrial processes.
