Serial-to-IP Devices Hide Thousands of Old and New Bugs
Summary
Operational Technology (OT) devices that convert serial data into IP communication are found to have thousands of vulnerabilities, affecting both older and newer models. These devices are increasingly targeted by attackers due to their critical role in industrial control systems and their often-unpatched state.
IFF Assessment
The article highlights widespread and unaddressed vulnerabilities in OT devices, making them ripe targets for exploitation by threat actors.
Defender Context
Defenders need to pay close attention to the security of serial-to-IP devices within their OT environments, as these are critical points of entry for attackers. Organizations should prioritize inventorying these devices, assessing their vulnerabilities, and implementing mitigation strategies like network segmentation and access controls to reduce their attack surface.
