In this article, we will explore what a digital twin is, its impact on cyber security, and the strategies to protect it.
What is a digital twin?
A digital twin is a digital representation of a real object, process, or system that allows monitoring, simulation, and optimization of its performance.
This concept, originating in Industry 4.0, leverages real-time data from sensors and IoT devices. The goal is to create a virtual environment that accurately replicates the behavior of the physical entity.
A digital twin is not just a digital copy—it also involves:
- The ability to analyze data;
- Performing advanced simulations;
- Making data-driven predictions.
Thanks to this technology, businesses can reduce downtime, enhance operational performance, and anticipate failures through predictive maintenance.
Digital twin adoption is rapidly expanding across industries such as manufacturing, healthcare, civil engineering, and smart cities. This highlights its enormous potential for process optimization and technological innovation.
How does a digital twin work?
The functioning of a digital twin revolves around a continuous cycle of data collection, analysis, and optimization. The process consists of three main phases:
- Real-time data collection
Digital twins gather information through IoT sensors, telemetry, 3D scanners, and other data sources. These devices continuously monitor the physical object, collecting metrics such as temperature, vibrations, wear, energy consumption, and other key parameters.
- Creation and updating of the digital replica
The collected data is sent to cloud or edge computing platforms, where it is processed to build a real-time updated digital representation. The accuracy of the virtual model depends on the quality and quantity of the data collected.
- Analysis and simulation
Artificial Intelligence (AI) and machine learning analyze historical and real-time data to detect patterns, anomalies, and trends. This enables more informed decision-making, performance optimization, and failure prediction before issues occur.
- Optimization and intervention
After analyzing data, the digital twin allows testing modifications and strategies in the virtual environment before applying them in the physical world. This reduces errors, minimizes downtime, and enhances operational efficiency.
Digital twin: examples and real-world applications
Digital twins are used across numerous industries to improve efficiency and reduce risks. Some concrete examples include:

Cyber security threats in digital twins
The growing adoption of digital twins is bringing significant benefits across various industries, but it also introduces new cyber security vulnerabilities.
Since these digital models rely on real-time data and their connection to the physical world, a cyberattack on digital twins can have devastating consequences—compromising critical infrastructure, causing economic damage, and putting people’s safety at risk.
Cyber threats targeting digital twins can be classified into different categories, including data theft, digital replica manipulation, and attacks that take direct control of the physical system.
Data theft and compromise
Digital twins depend on vast amounts of data collected from IoT sensors, business systems, and real-time analytics. This data may include confidential information, such as industrial designs, operational parameters, access credentials, and even sensitive customer data.
Common cyberattacks related to data theft include:
- Data breach
Cybercriminals infiltrate a digital twin’s system to steal strategic information, selling it on the dark web or using it for future attacks.
- Man-in-the-Middle (MitM)
Hackers intercept communications between the physical world and its digital twin, altering transmitted data and causing errors in the digital model.
- Malware and Ransomware
A malware attack could encrypt a digital twin’s data, blocking access to critical information and disrupting decision-making until a ransom is paid.
Manipulation of the digital replica
A major cyber security threat is the potential for hackers to alter the digital twin, leading to incorrect decisions or concealing impending failures. Since digital twins predict problems and optimize processes, a cyberattack could sabotage these functions, causing serious damage.
Examples of manipulation include:
- Tampering with operational parameters
A hacker could modify an industrial plant’s simulated temperature, making the digital twin appear normal while the physical system overheats.
- Inserting false data
If a digital twin receives inaccurate data, AI algorithms could make incorrect decisions, leading to failures or malfunctions.
- Interfering with updates
Attackers might manipulate updates to the digital twin, injecting vulnerabilities or rendering predictive maintenance data obsolete.
Risks of an unprotected digital twin
If a digital twin is not adequately protected, hackers could gain unauthorized access and even take control of the physical system. This is especially dangerous in critical sectors such as energy, transportation, and healthcare, where an intrusion could have life-threatening consequences.
Possible attack scenarios include:
- Industrial systems under attack
A cybercriminal could infiltrate a factory’s digital twins to sabotage production or disrupt the supply chain. - Compromised connected vehicles
Digital twins are used in the automotive sector to simulate vehicle behavior. If a hacker takes control, they could manipulate autonomous driving parameters, endangering passengers. - Vulnerable critical infrastructure
In smart cities, digital twins are used to monitor energy networks and public transportation. A cyberattack could disrupt power distribution or paralyze urban traffic.

Disruption of decision-making processes and downtime
Digital twins are essential tools for optimizing business operations and managing complex systems. If a cyberattack renders them unusable, companies may suffer massive financial losses.
Some techniques hackers use to disrupt digital twin functionality include:
- DDoS attacks
By overloading the digital twin’s servers, attackers can prevent access and halt business operations. - Sabotage of predictive maintenance
If a digital twin is compromised, it may no longer predict failures accurately, leading to increased downtime and repair costs. - Database corruption
A targeted attack on the digital twin’s databases could erase critical historical data, compromising the accuracy of simulations and forecasts.
Emerging threats: AI and advanced cyberattacks
With the integration of Artificial Intelligence and machine learning, digital twins are becoming increasingly autonomous. However, this evolution also introduces new threats:
