Industroyer: the biggest threat to industrial control systems since Stuxnet

ESET has discovered a malware that represents the biggest threat to critical infrastructure since Stuxnet. Named Industroyer, the malware has been designed to disrupt industrial processes.
Industroyer is a particularly dangerous threat, since it is capable of controlling electricity substation switches and circuit breakers directly. To do so, it uses industrial communication protocols used worldwide in power supply infrastructure, transportation control systems, and other critical infrastructure systems (such as water and gas).
These switches and circuit breakers are the digital equivalents of analogue switches; technically they can be engineered to perform various functions. Thus, the potential impact may range from simply turning off power distribution, cascading failures and more serious damage to equipment. The severity may also vary from one substation to another, as well. Needless to say, disruption of such systems can directly or indirectly affect the functioning of vital services.
Industroyer’s seriousness lies in the fact that it uses protocols in the way they were designed to be used. The problem is that these protocols were designed decades ago, and back then industrial systems were meant to be isolated from the outside world. Thus, their communication protocols were not designed with security in mind. That means that the attackers didn’t need to be looking for protocol vulnerabilities; all they needed was to teach the malware ‘to speak’ those protocols.For more details read this ESET white paper (PDF).
