Adversaries may move onto systems, such as those separated from the enterprise network, by copying malware to removable media which is inserted into the control systems environment. The adversary may rely on unknowing trusted third parties, such as suppliers or contractors with access privileges, to introduce the removable media. This technique enables initial access to target devices that never connect to untrusted networks, but are physically accessible.
Operators of the German nuclear power plant, Gundremmingen, discovered malware on a facility computer not connected to the internet. The malware included Conficker and W32.Ramnit, which were also found on eighteen removable disk drives in the facility. The plant has since checked for infection and cleaned up more than 1,000 computers. An ESET researcher commented that internet disconnection does not guarantee system safety from infection or payload execution.
Platforms: ICS
Determine if the target ICS/SCADA environment is susceptible to Replication Through Removable Media by examining operational technology systems and network architecture.
Review whether mitigations for T0847 are in place. If defenses are absent or misconfigured, this technique may be exploitable in the ICS environment.
Harden the system through operating system controls to prevent the known or unknown use of malicious removable media.
Enforce system policies or physical restrictions to limit hardware such as USB devices on critical assets.
