Cyberattacks have long been associated with data breaches, financial theft, and reputational damage. When an organization falls victim to such an attack, the immediate concerns usually revolve around stolen information, loss of customer trust, and the financial burden caused by system downtime and recovery efforts. However, this traditional view of cyber risk is rapidly becoming outdated.
A recent report by Deloitte South Asia highlights a far more alarming reality: cyberattacks are no longer confined to the digital realm. Instead, they are increasingly capable of causing real-world physical harm, including loss of human life. According to cybersecurity experts, the evolution of technology has significantly expanded the potential impact of these attacks.
One of the key drivers behind this shift is the growing integration of Information Technology (IT) with Operational Technology (OT). Industries such as transportation, public utilities, and aviation now rely heavily on interconnected systems that bridge digital networks with physical operations. While this integration improves efficiency and automation, it also creates new vulnerabilities. A breach in a digital system can now directly influence physical machinery, leading to potentially catastrophic consequences.
Consider, for example, a connected vehicle traveling at high speed. If hackers manage to gain control of its systems and disable critical functions such as steering or braking, the result could be a fatal accident. In such a scenario, the attack goes far beyond financial theft—it becomes a direct threat to human life.
Similarly, public infrastructure systems are increasingly at risk. Modern water treatment facilities rely on automated controls to regulate chemical levels. If cybercriminals infiltrate these systems, they could manipulate the composition of substances like chlorine in drinking water. An excessive increase could turn a vital resource into a toxic hazard, endangering entire communities.
The scale of this risk is further amplified by the rapid growth of connected devices. As noted by Gaurav Shukla, there are an estimated 30 billion Internet of Things (IoT) devices serving a global population of around 8 billion people. This means that, on average, each person is surrounded by multiple connected sensors and systems. While these devices enhance convenience and efficiency, they also present countless entry points for cyberattacks.
In this new landscape, cyber threats must be viewed not just as technical or financial risks, but as serious safety concerns. Strengthening cybersecurity is no longer optional—it is essential for protecting both digital assets and human lives.
