Understanding Cyber Threat Actors: Types and Classifications

Cybersecurity is a critical field where understanding the nature and motives of threat actors is essential. Threat actors are individuals or groups involved in cybercrime, and they can be classified based on their characteristics and behaviors. This article will explore the common types of threat actors, their motivations, and the risks they pose.

Common Types of Threat Actors

1. State Actors and State-Sponsored Actors
   • Operations: These actors work covertly, targeting organizations, public sectors, and critical infrastructures.
   • Activities: They engage in cyber warfare (disrupting infrastructure) and cyber espionage (gathering intelligence for national security or economic advantage).
2. Terrorists in Cyberspace
   • Activities: Utilize cyberspace for spreading propaganda, recruitment, radicalization, planning attacks, and financing terrorism.
3. Professional Criminals or Organized Crime
   • Subtypes:
     • Crime Facilitators: Provide technical support, such as renting botnets or offering remote access tools.
     • Scammers and Fraudsters: Focus on defrauding victims through identity theft and fraud.
     • Information Brokers: Collect and sell personal data.
     • Ransomware Groups: Use ransomware to extort money, sometimes offering ransomware as a service.
     • Hackers-for-Hire: Offer hacking services for a fee.
4. Hacktivists
   • Motive: Driven by social or political change.
   • Activities: Engage in website defacements, redirects, distributed denial of service (DDoS) attacks, and data leaks.
5. Script Kiddies and Crackers
   • Profile: Use readily available tools to hack, often out of curiosity or for fun, causing disruption without sophisticated skills.
6. Insiders
   • Profile: Employees or individuals with elevated access rights within an organization.
   • Motive: Often motivated by personal events, they can cause significant damage.

Dimensions for Categorizing Threat Actors

1. Motivation and Intent
   • Factors: Financial gain, ideology, revenge, curiosity, peer pressure.
2. Resources Available
   • Factors: Skills, finances, and other resources.
3. Impact Level
   • Factors: Financial losses, reputational damage, operational impact.
4. Modus Operandi
   • Factors: Methods and ways in which actors conduct their operations.
5. Overall Activities
   • Factors: Specific actions and operations they engage in.

Motivations of Threat Actors

• Financial Gain: Monetary incentives.
• Ideology: Driven by beliefs or political motives.
• Revenge: Personal vendettas.
• Curiosity/Recreation: For fun or challenge.
• Peer Pressure/Status: To gain prestige within a group.

Risks and Impact

• Financial Losses: Direct monetary impact.
• Reputational Damage: Harm to the organization’s or individual’s reputation.
• Operational Impact: Disruption of operations.

Categorizing Threat Actors Using a Circumflex

• Sophistication: Ranges from low to high as we move outward from the center.
• Motivation: Includes categories like status/prestige, ideology, financial gain, events, and curiosity/recreation.

Examples of Threat Actors in Categories

• Coders: Highly skilled, motivated by curiosity or financial gain.
• Hacktivists: Ideologically driven, moderate skills.
• Nation-State Actors: Highly skilled, often motivated by national interests.
• Organized Crime Groups: Skilled, financially motivated.
• Insiders: Employees with access, often motivated by revenge.
• Script Kiddies: Low-skilled, motivated by curiosity.
• Cyberpunks: More sophisticated than script kiddies, motivated by fun or status.

Application in Real-World Scenarios

Different groups can fit into multiple categories depending on their activities. For example, the group Anonymous conducts operations that can classify them as hacktivists or even cyberpunks. The ongoing Ukraine-Russia conflict also illustrates the involvement of various nation-state actors in cyber operations, showcasing the complexity and reach of these threat actors.

Understanding the typologies and motivations of threat actors is crucial for developing effective cybersecurity strategies. By recognizing the different categories and their associated risks, organizations can better prepare and defend against potential cyber threats.
