Almost every second industrial computer was subjected to malicious cyber activity in 2018

In 2018, Kaspersky Lab detected and prevented activity by malicious objects on almost half of Industrial Control System (ICS) computers protected by the company’s products and defined as part of an organization’s industrial infrastructure. 

The most affected countries were Vietnam, Algeria and Tunisia. These are some of the main findings of the Kaspersky Lab ICS CERT report on the industrial threat landscape in H2 2018.

Malicious cyber activities on ICS computers are considered an extremely dangerous threat as they could potentially cause material losses and production downtime in the operation of industrial facilities.

In 2018, the share of ICS computers that experienced such activities grew to 47.2% from 44% in 2017, indicating that the threat is rising.

According to the new report, the top-3 countries in terms of the percentage of ICS computers on which Kaspersky Lab prevented malicious activity were the following: Vietnam (70.09%), Algeria (69.91%), and Tunisia (64.57%). The least impacted nations were Ireland (11.7%), Switzerland (14.9%), and Denmark (15.2%).

Despite the common myth, the main source of threat to industrial computers is not a targeted attack, but mass-distributed malware that gets into industrial systems by accident, over the internet, through removable media such as USB-sticks, or e-mails. However, the fact that the attacks are successful because of a casual attitude to cybersecurity hygiene among employees means that they can potentially be prevented by staff training and awareness – this is much easier than trying to stop determined threat actors,” said Kirill Kruglov, security researcher at Kaspersky Lab ICS CERT.

Based on the same report, Kaspersky Lab has detected and blocked infections on 42.9% of ICS machines in Thailand. Overall, the Southeast Asia region recorded the second highest proportion of industrial computers on which malicious activity was prevented, with 57.8% of ICS machines affected during the second half of 2018. Internet remains the main source of threats in the region, with 39.5% of ICS computers on which internet threats were blocked.

“Southeast Asia is still among the regions most affected by ICS infections last year. For Thailand, we have found out that almost six-in-ten ICS machines in the country were subjected to threats during the last six months of 2018. Attacks against systems that control manufacturing processes can cause significant financial losses and disruption of crucial operations. We urge ICS operators to use adaptive solutions for these critical systems and networks. Most importantly, better threat awareness and improved habits should be observed by the entire workforce working in these companies,” commented Yeo Siang Tiong, General Manager for Southeast Asia, Kaspersky Lab.

Kaspersky Lab ICS CERT recommends implementing the following technical measures: 

  • Regularly update operating systems, application software on systems that are part of the enterprise’s industrial network.
  • Apply security fixes to PLC, RTU and network equipment used in ICS networks where applicable.
  • Restrict network traffic on ports and protocols used on edge routers and inside the organization’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, such as Kaspersky Industrial CyberSecurity. This solution includes network traffic monitoring, analysis and detection to secure OT and industrial infrastructure from both random malware infections and dedicated industrial threats.
  • Make sure security solutions are up-to-date and all the technologies recommended by the security solution vendor to protect from targeted attacks are enabled.
  • Provide dedicated training and support for employees as well as partners and suppliers with access to your network.
  • Use ICS network traffic monitoring, analysis and detection solutions for better protection from attacks potentially threatening technological process and main enterprise assets.
