Cyber-Kinetic Attacks: Safeguarding the Physical World from Digital Threats

This is adapted from a paper I submitted last year to a NATO research organization in my role within the Cyber-Physical Systems Security Institute.

Introduction

We are witnessing a growing convergence of cyberspace and the physical world. Computers are no longer confined to data centers or desktops – they increasingly monitor and control critical real-world processes in cyber-physical systems (CPS) like power grids, factories, and even surgery robots. Industrial control systems (ICS) that were once isolated began to connect to corporate networks and the internet. Programmable logic controllers (PLCs) in factories, smart building controls, and even smart weapons and military systems are being networked, raising new security concerns. Technologies that seemed futuristic, from robot-assisted surgery to automated industrial robots, are rapidly becoming a reality. Hundreds of thousands of industrial robots are already in operation worldwide (with Japan leading in adoption), and even surgical robots had entered hospitals.

With such cyber-connected machinery proliferating in critical domains, it became clear that malicious cyber attacks could no longer be treated as mere data breaches or IT disruptions – they have the potential to produce kinetic, real-world consequences.

Amid this backdrop, I introduce the term “Cyber-Kinetic Attacks.” As a researcher within the Cyber-Physical Systems Security Institute, with backgrounds in both cybersecurity and military sabotage, I believe it’s important to highlight this new threat. The proposed term denotes a new category of digital threats that can directly impact life, safety, and the environment – essentially merging cyber warfare with physical harm. In this paper, I define cyber-kinetic attacks, explain why a distinct term and discipline are warranted, and discuss the emerging threat landscape that makes protecting cyber-physical systems a matter of public safety.

Defining Cyber-Kinetic Attacks

Cyber-kinetic attacks are a subset of cyber attacks distinguished by their physical effects. In formal terms, a cyber-kinetic attack is a malicious digital intrusion that targets cyber-physical systems and causes direct or indirect physical damage, injury or death, or environmental impact solely through the exploitation of vulnerable information systems and processes. In other words, the attacker’s actions in cyberspace have kinetic (physical force or motion) outcomes in the real world. This concept merges the domains of information security and traditional kinetic warfare, highlighting that computer commands can now trigger destructive physical events much like bombs or sabotage tools.

It is useful to differentiate cyber-kinetic attacks from related terms. A cyber-physical attack broadly refers to any cyber-originated attack on a cyber-physical system, but not all such attacks cause tangible damage – for example, hacking a future smart meter to fraudulently reduce an electric bill is a cyber-physical attack with economic impact but no physical harm. Cyber-kinetic attacks, by contrast, specifically aim to produce damage or harm. They fall under the cyber-physical umbrella but represent the extreme end where life and property are at stake.

The term “cyber-kinetic” is deliberately chosen to evoke the idea of kinetic warfare, i.e. physical force conflict. Just as kinetic military attacks involve bullets or explosions, a cyber-kinetic attack uses digital means to unleash physical consequences. This nomenclature underscores that a hacker can become a saboteur – causing machinery to fail, mass transit rail to crash, or critical infrastructure to explode – all without ever physically touching the target.

To illustrate, consider a few hypothetical scenarios that fit this definition of cyber-kinetic attack: an attacker infiltrates a power plant’s control network and triggers a generator overload, causing a widespread blackout and equipment fires; a terrorist hacks into the software of an autonomous train control, resulting in a deadly crash; or a state-sponsored group remotely manipulates the controllers at a chemical plant or pipeline, causing a massive explosion and environmental disaster. In each case, the origin of the attack is cyber (malicious code or network intrusion), but the impact is kinetic – tangible destruction, damage or loss of life.

Drivers of the Cyber-Kinetic Threat Landscape

Several technological trends set the stage for the rise of cyber-kinetic risks. First, critical infrastructure and industrial systems became interconnected. Industrial Control Systems (ICS), the computerized brains running utilities like electricity, water, oil and gas, were traditionally kept isolated for safety. But as businesses seek efficiency and real-time data, these systems are increasingly linked with enterprise IT networks and even the internet. Controllers and sensors on factory floors are starting to use standard networking protocols, exposing them to remote access. This convergence means that a hacker across the globe could potentially reach systems that were once accessible only on-site.

Second, the proliferation of embedded computers in all kinds of equipment expanded the attack surface. Not only are power plants and factories controlled by computers, but so are increasingly elevators, building HVAC systems, and traffic lights. Smart appliances are being tested, meaning that even consumer devices will soon have microcontrollers and network connectivity, and therefore could be tampered with. The military domain also has numerous examples of cyber-physical convergence: missiles contained guidance computers that, in theory, could be hacked or fed false data; and as early as the Gulf War, strategists were exploring cyber methods to disable enemy command systems akin to a digital precision strike. This cross-pollination of computing into traditionally mechanical realms created new opportunities for malicious actors to cause havoc remotely.

Third, as mentioned, robotics and automation are surging. Industrial robots had been used since the 1970s, but their numbers ballooned recently. By some estimates there are roughly half a million robots in factories worldwide. Japan in particular embraced robotics, accounting for nearly half of new installations. At the same time, robots began moving beyond factory assembly lines into domains like medicine and public safety. For instance, experimental tele-surgery systems demonstrated that a surgeon could operate on a patient via robotic arms from across a room (or potentially, across a continent). Robots are also being tested for bomb disposal, firefighting, and other dangerous tasks traditionally done by humans. The implication is that a hacker who gains control of such robots or automated systems could redirect them to harmful purposes. One could imagine, for example, a rogue actor taking over an industrial robot on a production line and causing it to malfunction, injuring workers or wrecking products.

Finally, the growing reliance on networked sensors and actuators meant that even mundane services are becoming hackable. Cities are adopting centralized traffic control systems and utilities are deploying remote monitoring (SCADA) for pipelines and grids. While these advancements are improving efficiency, they are introducing single points of failure that a cyber attacker might exploit. A notable U.S. government exercise called Eligible Receiver 97 simulated exactly this: a “red team” of NSA hackers in 1997 tested how they could disrupt critical infrastructure. The result was alarming – using only publicly available hacking tools, they managed to infiltrate and take control of power grid controls and 911 emergency dispatch systems in nine major cities. Though no actual harm was done (it was a controlled exercise), this demonstration proved that adversaries could penetrate systems underpinning public safety. It underscored the reality that cyber attacks could turn off power or disable emergency communications, directly endangering lives. The exercise’s success directly influenced U.S. policy, spurring efforts like the Presidential Directive PDD-63 (May 1998) which identified cyber threats to critical infrastructures as a serious national security concern .

Real-World Incidents and Warnings

There were already real-world incidents foreshadowing cyber-kinetic attacks. Although full-blown cyber-physical catastrophes had not yet occurred, smaller-scale events and discoveries provided a warning of things to come:

• Airport Tower Disruption (1997): In March 1997, a 14-year-old hacker in Massachusetts penetrated a telephone company switching system, causing a crash that knocked out power and phone lines at an airport for six hours. This disrupted all communication between the Worcester airport control tower and aircraft, essentially paralyzing aviation operations during that time . Fortunately, no accidents occurred, but the incident demonstrated that a teenager with a computer could inadvertently achieve effects akin to sabotaging an airport’s electrical and communication systems. A U.S. Attorney noted “These are not pranks… hackers should know they will be prosecuted,” highlighting how seriously this near-miss was taken . The Worcester case is an early example of a cyber intrusion leading to physical-world safety risks (in this case, the inability to coordinate air traffic).
• Pipeline Explosion Story (1982): An apocryphal yet widely-circulated story suggests that the concept of cyber-kinetic attacks actually dates back to the Cold War. According to this account (first revealed publicly in the mid-1990s), the CIA learned of Soviet thieves stealing industrial control software for gas pipelines. In response, CIA operatives reportedly planted a logic bomb in the code. When the Soviets eventually ran the tainted software on a Siberian natural gas pipeline, it allegedly caused the pipeline’s pressure valves to malfunction, leading to a monumental explosion visible from space. While no official source has confirmed this incident, it is often cited as an early instance of digital sabotage causing kinetic devastation – essentially a covert cyber attack used as a weapon against critical infrastructure. True or not, it shows that the military and intelligence community had recognized decades ago that code could be turned into a destructive agent.
• Chernobyl (CIH) Virus (1998): In 1998, a computer virus named CIH (also known as “Chernobyl”) was discovered, and it soon gained notoriety as one of the most destructive malware strains at the time. Unlike typical viruses that merely delete files, CIH was designed to corrupt the flash BIOS of infected computers – effectively bricking the hardware by overwriting firmware critical to booting the PC. The virus activated on April 26, 1999 (the anniversary of the Chernobyl nuclear disaster, hence the nickname) and wiped critical system data on tens of thousands of machines worldwide. While CIH did not directly kill or injure people, it caused physical damage to computer hardware on a large scale. This was a wake-up call that malicious code could inflict tangible, costly damage beyond mere data loss. One might imagine a similar attack tailored for controllers in a factory robot – the result could be life-threatening. CIH thus bridged the gap between cyberspace and physical consequence, albeit in the realm of computer equipment; it foreshadowed how malware could just as well target embedded systems that interface with the physical world.

These cases, along with multiple well-publicized “cyber-terrorism” scares, are moving the conversation beyond hypothetical scenarios. No longer are kinetic cyber threats purely theoretical. Indeed, leaders in government and industry are beginning to acknowledge that protecting cyberspace is about protecting lives and society. As a U.S. Senate testimony observed, an adversary might cripple an enemy nation by attacking its civilian infrastructure via cyber means – blurring the line between an act of war and a criminal hack. It became “vital we secure these systems properly in order to protect lives, well-being and the environment” In short, cybersecurity was no longer just about data – it was about public safety.

Why We Need the Term “Cyber-Kinetic”(and a New Approach)

The introduction of the term cyber-kinetic attacks is not just semantics; it serves to focus attention on a critical subset of security issues that had been largely overlooked. Cybersecurity as a field is primarily concerned with protecting information: keeping data confidential, preventing fraud, or ensuring network uptime. Concepts like the CIA triad (Confidentiality, Integrity, Availability) dominated the discourse. However, when dealing with cyber-physical systems that can kill or injure, traditional security paradigms need to be expanded. Safety and resilience under malicious attack have to become paramount design goals. I argue that a separate term and discipline – cyber-kinetic security – is needed for several reasons:

Clarity of Focus: Using a dedicated term highlights the difference in consequences. Most cybersecurity incidents involve financial loss or data breaches, which, while serious, do not usually put human lives at immediate risk. In contrast, cyber-kinetic incidents directly threaten human safety or the environment (think of a hacker causing a train derailment or poisoning a water supply via a control system hack). By naming this category, we make clear that these are not “ordinary” cyber attacks and should not be lumped in with website defacements or credit card theft. The term thus helps galvanize awareness among stakeholders (governments, engineers, academia) that “bits” can indeed break things in the physical world.

Interdisciplinary Skills: Defending against cyber-kinetic threats requires a blend of expertise that traditional IT security professionals may not possess. For example, securing a power grid substation or a gas pipeline’s SCADA system calls for knowledge of control engineering, physical process safety, and industry-specific protocols – in addition to computer science. It’s a fusion of cybersecurity, engineering, and public safety. By treating cyber-kinetic security as its own domain, we can push for specialized training programs, certifications, and university curricula that produce professionals adept in both IT and OT (operational technology). In the coming years, we may see certifications focusing on industrial control security. Early movement in this direction is already apparent; for instance, the U.S. Department of Homeland Security has identified control system cyber specialists as a distinct workforce category. The new term helps justify why a pipeline control engineer with hacking skills (or vice versa) is as crucial to hire as a network administrator.

Policy and Prioritization: Having a crisp term like cyber-kinetic can influence policymakers to prioritize resources and regulations for this area. It conveys a sense of urgency – these are effectively cyber-enabled weapons we are defending against. Just as governments have safety standards for automobiles and airplanes, they may need to regulate the security of software in cars or medical devices to prevent cyber-kinetic sabotage. Today such regulation is non-existent, but forward-looking discussions suggested that new safety certifications would emerge. For example, one might envision requiring that any network-connected robot undergo a cyber-kinetic risk assessment. Using a distinct term in policy debates (e.g. “We must address cyber-kinetic risks to critical infrastructure”) elevates the issue above the noise of general cybersecurity, which is often associated mainly with viruses and hackers stealing information. Indeed, leaders started warning that the most significant cyber threats were those aimed at critical infrastructure and life support systems, essentially describing cyber-kinetic scenarios.

Strategic Importance: From a national security perspective, cyber-kinetic capabilities blur the line between a hacker and a combatant. By naming and studying this threat, military and defense organizations can develop doctrines and defenses for “cyber warfare” that accounts for physical outcomes. Traditional kinetic war has established norms and deterrence strategies; similarly, acknowledging cyber-kinetic attacks leads to discussions on deterrence (e.g. should a cyber attack that causes deaths be met with a conventional military response?). It also encourages international dialogue on norms – for instance, perhaps an agreement that power plants and hospitals should be off-limits for nation-state cyber operations (akin to protections for civilian facilities in war). While such discussions are nascent, having a term helps strategists conceptualize this new mode of conflict. Some military planners had begun using phrases like “non-kinetic warfare” and considering cyber attacks on par with physical attacks. My terminology choice of cyber-kinetic explicitly bridges those concepts, making clear that cyber attacks can have kinetic effects equivalent to traditional attacks and thus must be taken as seriously.

In summary, coining “cyber-kinetic attacks” is about driving a mindset shift. It compels organizations to consider worst-case scenarios: not just data theft or downtime, but catastrophic outcomes like explosions, vehicle crashes, and loss of life caused by hacking. This, in turn, leads to rethinking security practices. For example, the standard IT security focus on confidentiality is far less important in an electric grid context than integrity and availability of controls – and even those must be balanced with safety overrides. We may need to borrow practices from the safety engineering world (fault-tolerance, failsafes, redundancy) and integrate them with cybersecurity. The term signals that protecting cyber-physical systems is a “whole new ballgame” requiring new frameworks.

Conclusion

As we stand on the cusp of a new millennium, the writing is on the wall: the boundary between cyberspace and the physical world is dissolving. The very technologies enriching our lives carry a dual-use nature. In the hands of adversaries, they become instruments for potential harm. Cyber-kinetic attacks are not science fiction but an emerging reality, as early incidents and government exercises have shown. This paper introduced the term to crystallize the concept that digital attacks can have deadly real-world effects. We have outlined how the rise of connected cyber-physical systems demands a commensurate evolution in security thinking, education, and policy.

Moving forward, stakeholders must treat cyber-kinetic security with the urgency historically reserved for physical terrorism or natural disasters. This means investing in resilient system designs, such as control systems that can gracefully degrade instead of catastrophically fail under attack. It means training a new generation of security professionals versed in both bits and bolts – able to understand a firewall log and a valve diagram alike. It also means establishing clear responsibilities and response plans: if a major cyber-kinetic incident occurs, how do emergency services, cybersecurity experts, and engineers coordinate a response to save lives and restore safe conditions?

Ultimately, cyber-kinetic security is about protecting the kinetic world – the world of people and critical infrastructures – from cyber threats. By introducing this term and framework now, we hope to encourage proactive measures rather than reactive ones. The more we connect the cyber and physical worlds, the greater the cyber threat to our physical safety. It is our responsibility to ensure that the digital revolution of the 1990s and beyond does not inadvertently expose society to new forms of harm. In the future, success in cybersecurity will not be measured only by confidentiality of data, but by the safety and trustworthiness of the automated systems that underlie our very lives. The time to prepare is now.
