In the manufacturing sector, 41.2 percent of industrial control systems (ICS) computers were attacked by malicious software at least once.
Conducting an analysis of ICS computers protected by Kaspersky Lab solutions, researchers were able to cull the information for the reported entitled, “Threat Landscape for Industrial Automation Systems in H1 2018.”
The data collected during this time also uncovered the countries most impacted by ICS computer attacks were Vietnam, Algeria and Morocco. The safest region for industrial machines was Denmark.
There was a consistent rise in the percentage of attacks on ICS computers, researchers said in the report.
Data show in 2017, the percentage of ICS computer attacked was 36.61 in the first half of the year and 37.75 percent in the second half. The company’s experts believe this threat is of concern as it continues to grow over time.
The top countries by the number of ICS computers attacked in the first half of 2018 were Vietnam (75.1 percent), Algeria (71.6 percent), and Morocco (65 percent). In regard to the least attacked industrial enterprise facilities, the top three countries were Denmark (14 percent), followed by Ireland (14.4 percent), and Switzerland (15.9 percent).
Developing economies are accounting for the highest number of ICS computers attacked, while developed regions have the lowest number of targeted ICS computers, researchers said.
Kaspersky Lab researchers have also noticed a trend in the source of cyber threats, with the largest number of threats coming from the Internet. This has become the main source of infection for ICS computer attacks – with 27 percent of threats received from the World Wide Web, 8.4 percent received through removable storage media, and 3.8 percent from mail clients.
“The percentage of cyberattacks on ICS computers is a concern,” said Kirill Kruglov, security researcher at Kaspersky Lab. “Our advice is to pay attention to systems’ security from the very beginning of their integration when the systems’ elements are first connected to the internet. Neglecting security solutions at this stage could lead to dire consequences.”
