Riddled with flaws, serial-to-Ethernet converters endanger critical infrastructure
Summary
A new study by Forescout researchers revealed that serial-to-Ethernet converters, crucial for connecting serial devices to TCP/IP networks in critical infrastructure, are laden with numerous vulnerabilities and outdated open-source components. These flaws allow attackers to potentially take control of essential equipment like PLCs, POS systems, and patient monitors, with implications for industrial, retail, and healthcare sectors.
IFF Assessment
The discovery of widespread vulnerabilities in critical infrastructure components like serial-to-Ethernet converters presents a significant threat to operational technology (OT) environments.
Defender Context
Defenders should be aware of the significant security risks posed by serial-to-Ethernet converters, especially in OT environments where these devices are prevalent. Organizations need to prioritize the discovery and secure configuration of these devices, along with implementing robust network segmentation and monitoring to detect any malicious activity targeting them.
