KSA: industrial control systems spyware and malicious scripts on the rise in H1 2021

According to Kaspersky ICS CERT, almost one in three industrial computer was subject to malicious activity in H1 2021. During the first half of 2021, cybercriminals intensively used various types of spyware and malicious scripts while performing their attacks. These types of threats are growing for the second six-month period and pose a big challenge to industrial control systems (ICS).

Attacks against industrial organizations are particularly dangerous as cybercriminals might steal data and money and disrupt the established system of production. An increase in the diversity of threats to such networks indicates the growth of the attackers’ interest in them and, consequently, an increase in the need to reliably protect them.

According to the “Threat Landscape for Industrial Automation Systems Report”, Kaspersky security solutions blocked over 20,000 malware variants during the first six months of 2021. To find out more about how the ICS threat landscape changed during the reporting period, Kaspersky researchers analyzed various types of malware used during cyberattacks against industrial systems. They subsequently found that the percentage of spyware and malicious scripts used against ICS has grown continuously over the past half a year. In fact, spyware (Trojan-Spy malware, backdoors and key loggers), which is mostly used to steal money, are up by 0.4 percentage points in Saudi Arabia. At the same time, malicious scripts grew by 0.2 percentage points. Threat actors use such scripts on various websites hosting pirated content to redirect users to sites which distribute spyware or malware designed to mine cryptocurrency without the user’s knowledge.

“Industrial organizations always attract attention from both cybercriminals and politically-motivated threat actors. Reflecting on the previous half year, we have seen among other findings, growth in the number of cyberespionage and malicious credential stealing campaigns. Their success has most likely been the main factor raising the ransomware threat to such a high degree. And I see no reason why some of the APT groups won’t benefit from these credential stealing campaigns as well.” comments Evgeny Goncharov, security expert at Kaspersky.

To keep your ICS computers protected from various threats, Kaspersky experts recommend:

  • Using security solutions for OT endpoints and networks, such as Kaspersky Industrial CyberSecurity to ensure comprehensive protection for all industry critical systems.
  • Regularly updating operating systems and application software that are part of the enterprise’s industrial network. Apply security fixes and patches to ICS network equipment as soon as they are available.
  • Undertaking dedicated ICS security training for IT security teams and OT engineers, which is crucial to improve responses to new and advanced malicious techniques.
  • Conducting regular security audits of OT networks to identify and eliminate security issues.
  • Providing the security team responsible for protecting industrial control systems with up-to-date threat intelligence. ICS Threat Intelligence Reporting service provides insights into current threats and attack vectors, as well as the most vulnerable elements in OT and industrial control systems and how to mitigate them.
  • Using ICS network traffic monitoring, analysis and detection solutions for better protection from attacks potentially threatening technological processes and main enterprise assets.
