ICS Computers in Western Countries See Increasing Attacks: Report

Industrial control system (ICS) computers in the Western world have been increasingly attacked, but the percentages are still smaller compared to other parts of the globe, according to Kaspersky’s latest ICS threat landscape report.

In the first half of 2023, Kaspersky blocked threats on 34% of the ICS computers protected by its products, with the second quarter seeing the highest quarterly level since 2019. 

Industrial systems from which Kaspersky collected data include SCADA servers, historians, OPC systems, engineering and operator workstations, HMIs, computers used to manage industrial networks, and devices that are used to develop industrial automation software.

In the first half of the year, Western Europe, the US and Canada, Australia and New Zealand, and Northern Europe saw the highest increase in attack percentage points. This is interesting because, as Kaspersky pointed out, these are the regions that historically have had the lowest percentages of ICS devices on which malicious elements were blocked. 

The biggest increase was seen in Western Europe, where the percentage of attacked ICS devices increased from 14.2% in H2 2022 to 18.8% in H1 2023. 

On the other hand, Western countries still saw the lowest attack percentages. The highest percentages of attacked devices were in Africa, Southeast Asia, Middle East, Central Asia, East Asia, Latin America and Russia.
