By Eduard Kovacs on February 24, 2021 A total of 15 threat groups have been observed targeting industrial organizations, according to industrial cybersecurity firm Dragos. Dragos on Wednesday released its ICS Cybersecurity Year in Review report for 2020, which covers the industrial control systems (ICS) threat landscape and vulnerabilities disclosed last year. It also shares insights from the lessons learned by Dragos as a result of its work in 2020, and provides recommendations for industrial organizations on securing their networks. In 2018, Dragos reported seeing five groups that had either attacked ICS directly or had shown an interest in gathering information on these types of systems. The next year, the company reported that the number had grown to nine, and now there are a total of 15 activity groups.
