Introduction
The metaverse, as a new frontier for human-digital interactions, is rapidly evolving. This virtual realm—emerging from the integration of virtual reality (VR), augmented reality (AR), and mixed reality (MR) technologies—has the potential to revolutionize various industries, including gaming, commerce, and education. However, the vulnerabilities inherent in this complex digital ecosystem create opportunities for cyber exploitation. From digital identity theft to fraud, money laundering, and more sophisticated attacks like ransomware and infrastructure sabotage, the metaverse provides fertile ground for illicit activities.
Thus, developing a comprehensive framework to investigate and analyze cybercrimes in this space is crucial. Given the rapid growth of users and commercial activities in the metaverse, analyzing and preventing these threats is essential.
The proposed framework, developed based on the guidelines of NIST (National Institute of Standards and Technology), offers the necessary tools for identifying and investigating cybercrimes in this environment. Designed in alignment with NIST standards, this framework enables cybersecurity experts to systematically and efficiently identify, investigate, and analyze crimes occurring in the metaverse.
Metaverse: A Novel Opportunity with Security Challenges
In recent years, the metaverse has grown exponentially, becoming a key focus in the global technology and business landscape. It offers immersive 3D virtual environments where users can engage in various activities through avatars, from purchasing digital real estate to attending virtual concerts and seminars.
However, this rapid advancement comes with significant security challenges:
- Economic Crimes
From money laundering to theft of digital assets, the decentralized nature of the metaverse makes it a breeding ground for such crimes.

Users may become targets of cyberattacks that threaten their digital or personal identity.
- Fraud
Examples include selling fake assets or making false promises in virtual environments.
- Privacy Breaches
Given the metaverse’s reliance on user data, privacy threats are a pressing concern.
Introducing the Cyber Investigation Framework for the Metaverse
The real world and the metaverse are interconnected and influence each other. Therefore, before initiating investigations, inspectors must determine how crimes or issues impact the real world and then define the scope of each investigative phase. The Metaverse Cyber Investigation Framework is a structured tool designed to facilitate evidence identification, collection, and analysis in virtual environments. This framework is based on NIST guidelines and the Cyber Kill Chain (CKC).
The framework categorizes crimes into the following four types:
- Internal-Internal
Crimes that occur entirely within the metaverse, such as hacking digital assets.
- External-Internal
Crimes that originate in the real world and infiltrate the metaverse, such as malware dissemination via email.
- Internal-External
Crimes that start in the metaverse and impact the real world, such as accessing real-world bank accounts using data obtained in the metaverse.
- External-External
Crimes that occur in the real world but indirectly affect the metaverse, such as attacks on the network infrastructure supporting the metaverse.
The Importance of a Cyber Investigation Framework for the Metaverse
- Complexity and Diversity of Threats in the Metaverse
The metaverse, due to its integration of various technologies, has evolved into a highly complex environment. This complexity stems from its multilayered nature, where user interactions occur through virtual avatars in 3D spaces and are directly linked to sensitive user data, financial transactions, and commercial activities. A wide range of cybercrimes, including financial crimes, intellectual property theft, and personal crimes, occur within the metaverse. Threats in this space can arise from personal data breaches, smart contract exploitation, and network vulnerabilities.
- Legal Challenges and Global Standards
Currently, the metaverse lacks a defined legal framework to combat cybercrimes, and there are no global standards for investigating cybercrimes within it. This absence of comprehensive standards and regulations makes addressing cybersecurity threats in this space particularly challenging. Therefore, research and security frameworks must be designed and implemented based on globally recognized principles such as NIST standards.
The Proposed Cybersecurity Framework for the Metaverse
- Leveraging NIST Standards
The proposed cybersecurity framework for the metaverse is based on the well-established NIST model, which consists of five primary phases: identify, protect, detect, respond, and recover. However, to adapt this model to the specific characteristics of the metaverse, we have expanded it to not only address threat identification and response but also emphasize analyzing and collecting cyber evidence.
- Identifying Threats and Vulnerabilities
This phase involves identifying potential threats and system vulnerabilities in the virtual metaverse. These vulnerabilities may include weaknesses in simulation software, blockchain vulnerabilities, or security flaws in virtual avatar designs.
- Protecting Digital Assets and Users
In this phase, measures are implemented to safeguard assets and user information. For instance, advanced encryption can be utilized to protect transaction data and personal information.
- Timely Detection of Attacks
Rapid identification of attacks and threats is crucial. In the metaverse, this entails detecting suspicious activities in real-time, such as unexpected changes in avatar behavior, unauthorized user simulations, or suspicious financial transactions.
- Detailed Investigation and Analysis
Cybercrime investigations in the metaverse require collecting digital evidence, analyzing decentralized data, and simulating events. This phase focuses on thoroughly analyzing cyberattacks, including simulating attacks and tracing digital footprints.
- Response and Recovery
Following the identification and analysis of attacks, the response and recovery phase begins. This phase involves implementing measures to mitigate the effects of the attack and restore damaged systems and information. Additionally, improving systems and implementing security changes to prevent similar attacks in the future is part of this phase.
Classification of Artifacts and Relation to the Cyberattack Lifecycle
This framework identifies various artifacts in the metaverse and associates them with different stages of the cyberattack lifecycle. These artifacts include:
