Unsophisticated Cyber Actors Targeting Critical Infrastructure: A Growing Threat

TL;DR

Unsophisticated cyber actors are increasingly targeting ICS/SCADA systems in critical infrastructure sectors, particularly in the Oil and Natural Gas industries. These attacks, though basic, can lead to significant disruptions due to poor cyber hygiene and exposed assets. CISA urges asset owners and operators to implement mitigation strategies to reduce risks.

Unsophisticated Cyber Actors Targeting Critical Infrastructure

The Cybersecurity and Infrastructure Security Agency (CISA) has observed an alarming trend of unsophisticated cyber actors targeting Industrial Control Systems (ICS) and Supervisory Control and Data Acquisition (SCADA) systems within critical infrastructure sectors in the United States. These sectors, particularly Oil and Natural Gas under the Energy and Transportation Systems, are increasingly vulnerable to basic and elementary intrusion techniques¹.

The Threat Landscape

While the methods employed by these actors are often rudimentary, the impact can be severe due to poor cyber hygiene and exposed assets. These vulnerabilities can escalate threats, leading to consequences such as:

• Defacement: Unauthorized modifications to digital interfaces.
• Configuration Changes: Alterations to system settings that can disrupt operations.
• Operational Disruptions: Interruptions in critical processes.
• Physical Damage: In severe cases, physical harm to infrastructure.

Mitigation Strategies

CISA strongly urges critical infrastructure asset owners and operators to review and implement the following mitigation strategies to reduce the risk of potential intrusions:

Conclusion

The increasing threat of unsophisticated cyber actors targeting critical infrastructure highlights the need for robust cybersecurity measures. By implementing the recommended mitigation strategies, asset owners and operators can significantly reduce the risk of intrusions and protect essential systems from potential disruptions and damage.
