CISA alert on ICS, SCADA devices highlights growing enterprise IoT security risks

CISA alert on ICS, SCADA devices highlights growing enterprise IoT security risks

  • Written by Hollie Hennessy / Dark Reading
  • 18th April 2022

On April 13, the Department of Energy (DoE), the Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA), and the Federal Bureau of Investigation (FBI) released a joint Cybersecurity Advisory to warn that certain industrial control systems (ICS) and supervisory control and data acquisition (SCADA) devices can be targeted by advanced persistent threat (APT) actors who have the capability to gain full system access.

The alert warned that vulnerable products include Schneider Electric programmable logic controllers, OMRON Sysmac NEX PLCs and Open Platform Communications Unified Architecture (OPC UA) servers.

Once on the operational technology (OT) network, APT actors can utilize certain custom-made tools to scan for vulnerable devices, and then exploit and subsequently take control of them.

The advisory also noted a critical issue with Windows-based engineering workstations. Systems in the OT environment, or even on the IT side, can be compromised using an exploit targeting vulnerable motherboard drivers.

Utilizing these techniques, importantly and worryingly, could allow APT actors to elevate their privileges, move laterally within the OT environment to other devices, and disrupt or crash critical devices.

With recent events, such as the Colonial Pipeline attack, which saw the entire OT environment shut down (despite not even originating with OT devices), plus the rise of ransomware and the threat of politically motivated national state actors, those in critical national infrastructure need to act fast.

DoE, CISA, NSA, and the FBI urge organizations, especially those in the energy sector, to implement detection and mitigation recommendations to detect APT activity and harden their ICS/SCADA devices.

    Late last year, a group of threat actors managed to obtain “verified publisher” status through the Microsoft Cloud Partner Program (MCPP).

    A new shape-shifting robot can reversibly morph between liquid and solid shapes. The novel design was created by a team of engineers from The Chinese University of Hong Kong and Carnegie Mellon University.
