Common ICS Cybersecurity Myth #5: Financially Motivated Cyberattacks

Misconceptions about ICS/OT cybersecurity are stubborn. This “mythbusting” blog series dispels five common myths related to ICS cybersecurity. Catch up on previous entries if you’re interested:

Now, let’s dive in.

ICS Cybersecurity Myth #5

Contrary to the common belief that attackers are primarily financially motivated, and that there is not much for them to gain by attacking an industrial network, there could be many reasons why hackers would seek to attack and gain access to industrial networks — especially critical infrastructure such as electricity, gas, and water.

Cybercriminals are financially motivated, but nation states and hacktivists may have different motives beyond the financial. State-sponsored actors and hacktivists may want to gain access to vulnerable critical infrastructure or defense strategy without causing immediate damage, and use their access to other nations’ critical infrastructure to influence policies and negotiations — or they may want to cause damage or outages during potential war situations to bring about economic impacts. (All of these are hypothetical — but feasible — scenarios.)

Stuxnet attack ruined almost 20% of Iran’s nuclear centrifuges

2013

Cyberattack on a German steel mill resulted in massive physical and equipment damages

2015

BlackEnergy3 cyberattack on Ukrainian power utilities caused power loss for more than 225,000 customers

2017

WannaCry attack affected 200,000+ systems in 150 countries — although not explicitly designed to target ICS, it impacted ICS as well

2017

NotPetya attack prevented Maersk from locating and routing shipments, caused up to EUR 300 million in losses (public reports)
