More than 40% of industrial control systems computers attacked in 1H2018-Kaspersky

12 Sep 2018

More than 40% of all industrial control system (ICS) computers protected by solutions by cybersecurity firm Kaspersky Lab were attacked by malicious software at least once during the first half of 2018, said the firm.

The most affected countries were Vietnam, Algeria and Sri Lanka, while the safest region for industrial machines was Denmark, according to the Kaspersky Lab ICS CERT report on the industrial threat landscape in 1H2018.

Cyberattacks on industrial computers are considered to be an extremely dangerous threat as they cause material losses and production downtime for a whole system. Moreover, industrial enterprises knocked out of service can seriously undermine a region’s social welfare, ecology and macroeconomics. 

Statistics collected by Kaspersky Lab researchers show that this kind of threat is of growing concern. In 1H2018, 41.2% of ICS computers were attacked at least once. Moreover, this is a continuation of a trend: in 2017, the figure increased from 36.61% in the first half of the year to 37.75% in the second half.

Trends reveal that developing economies account for highest numbers of ICS computers attacked, while developed regions have the lowest number of targeted ICS computers.

Top countries by the number of ICS computers attacked in 2018 were Vietnam, where 75.1% of ICS computers were attacked, Algeria, with 71.6% and Morocco with 65%. The least attacked computers turned were in Denmark with 14% attacked computers in industrial enterprises, followed by Ireland with 14.4% and Switzerland close behind, accounting for 15.9%.

The largest number of threats come from the Internet, which over the years has become the main source of infection for ICS: 27% of threats are received from the world wide web; while removable storage media is ranked second with 8.4%. Mail clients occupy third place in terms of volume– they represent 3.8% of threats.

“The percentage of cyberattacks on ICS computers is a concern. 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,” said Kirill Kruglov, a security researcher at Kaspersky Lab.

Kaspersky Lab ICS CERT recommends implementing the following technical measures:

  • Regularly update operating systems, application software and security solutions on systems that are part of the enterprise’s industrial network.
  • Restrict network traffic on ports and protocols used on edge routers and inside the organisation's OT networks.
  • Audit access control for ICS components in the enterprise’s industrial network and at its boundaries.
  • Deploy dedicated endpoint protection solutions on ICS servers, workstations and HMIs to secure OT and industrial infrastructure from random cyberattacks; and network traffic monitoring, analysis and detection solutions for better protection from targeted attacks.
  • Provide dedicated training and support for employees as well as partners and suppliers with access to your network.
