During 2H 2020, 449 vulnerabilities affecting ICS products from 59 vendors were disclosed.

"Nation-state actors are clearly looking at many aspects of the network perimeter to exploit, and cybercriminals are also focusing specifically on ICS processes, which emphasizes the need for security technologies such as network-based detection and secure remote access in industrial environments. It is heartening to see a growing interest in ICS within the security research community, as we must shine a brighter light on these vulnerabilities in order to keep threats at arm's length."

The number of ICS vulnerabilities disclosed in 2020 increased by more than 30% compared to 2018 and nearly 25% compared to 2019.

The research team discovered and disclosed 41 vulnerabilities during the 2H 2020, affecting 14 vendors.
