APT Cyber Tools Targeting ICS/SCADA Devices

APT actors could elevate privileges, move laterally within an OT environment, and disrupt critical devices or functions.

The Department of Energy (DOE), the Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA), and the Federal Bureau of Investigation (FBI) are releasing this joint Cybersecurity Advisory (CSA) to warn that certain advanced persistent threat (APT) actors have exhibited the capability to gain full system access to multiple industrial control system (ICS)/supervisory control and data acquisition (SCADA) devices, including:

  • Schneider Electric programmable logic controllers (PLCs),
  • OMRON Sysmac NEX PLCs, and
  • Open Platform Communications Unified Architecture (OPC UA) servers.

The APT actors have developed custom-made tools for targeting ICS/SCADA devices. The tools enable them to scan for, compromise, and control affected devices once they have established initial access to the operational technology (OT) network. Additionally, the actors can compromise Windows-based engineering workstations, which may be present in information technology (IT) or OT environments, using an exploit that compromises an ASRock motherboard driver with known vulnerabilities. By compromising and maintaining full system access to ICS/SCADA devices, APT actors could elevate privileges, move laterally within an OT environment, and disrupt critical devices or functions.

DOE, CISA, NSA, and the FBI urge critical infrastructure organizations, especially Energy Sector organizations, to implement the detection and mitigation recommendations provided in this CSA to detect potential malicious APT activity and harden their ICS/SCADA devices.
