Types of Threat Actors and Their Motivations
A threat actor is any individual, group, or entity that poses a cybersecurity threat by attempting to exploit vulnerabilities in an organization's systems, networks, or data. Threat actors vary in their skills, goals, and resources, and understanding their motivations helps organizations defend against them effectively.
In this lesson, we will explore different types of threat actors, their objectives, and real-world examples of their attacks.
Categories of Threat Actors
Threat actors can be broadly categorized into the following types:
- Script Kiddies
- Hacktivists
- Cybercriminals
- Insider Threats
- Nation-State Actors (State-Sponsored Attackers)
- Advanced Persistent Threats (APTs)
Each of these actors operates with different intentions, techniques, and resources.
1. Script Kiddies
Definition: Script kiddies are amateur hackers who lack deep technical knowledge and rely on pre-built tools and scripts to launch cyberattacks.
Motivations:
- Thrill-seeking – Hacking for fun, recognition, or to prove a point.
- Vandalism – Defacing websites or disrupting services for amusement.
- Bragging Rights – Competing with peers in online hacker forums.
Techniques Used:
- Using freely available hacking tools (e.g., LOIC for DDoS attacks).
- Exploiting known vulnerabilities with automated scripts.
- Defacing websites by injecting malicious code.
Example:
A 16-year-old script kiddie downloads a tool to launch a DDoS (Distributed Denial-of-Service) attack against a gaming server, temporarily taking it offline.
Threat Level: Low to Moderate (Dependent on the tools used).
2. Hacktivists
Definition: Hacktivists are politically or ideologically motivated hackers who use cyberattacks to promote their beliefs or expose corruption.
Motivations:
- Political activism – Attacking government websites to protest policies.
- Corporate revenge – Targeting organizations they believe engage in unethical practices.
- Awareness campaigns – Leaking sensitive data to expose wrongdoing.
Techniques Used:
- Doxing – Exposing personal or confidential information.
- Defacement attacks – Replacing website content with political messages.
- DDoS attacks – Overloading servers to disrupt online services.
Example:
The hacktivist group Anonymous has conducted numerous cyberattacks against governments and corporations to protest censorship and human rights violations.
Threat Level: Moderate to High (Depending on the sophistication of the attack).
3. Cybercriminals
Definition: Cybercriminals are financially motivated attackers who use cybercrime to steal money, data, or other valuable assets.
Motivations:
- Financial gain – Stealing banking credentials, credit card information, or cryptocurrencies.
- Ransom demands – Encrypting files with ransomware and demanding payment.
- Fraud – Using phishing, identity theft, or business email compromise (BEC) scams.
Techniques Used:
- Phishing attacks – Tricking users into revealing sensitive information.
- Malware distribution – Deploying keyloggers, trojans, and ransomware.
- Dark web transactions – Selling stolen data or hacking tools.
Example:
A cybercriminal deploys ransomware, encrypting a company's critical files and demanding a $1 million Bitcoin payment to restore access.
Threat Level: High (Sophisticated, well-funded, and persistent).
4. Insider Threats
Definition: Insider threats come from employees, contractors, or business partners who misuse their access privileges for malicious intent or negligence.
Motivations:
- Financial incentives – Selling company secrets or customer data.
- Revenge – Disgruntled employees damaging systems before quitting.
- Negligence – Unintentionally exposing sensitive information (e.g., sending confidential emails to the wrong recipient).
Techniques Used:
- Data theft – Copying sensitive files onto USB drives.
- Privilege abuse – Misusing admin rights to bypass security controls.
- Sabotage – Deleting databases or deploying malware.
Example:
An IT administrator leaving a company disables security controls and deletes customer records out of revenge.
Threat Level: High (Difficult to detect and prevent).
5. Nation-State Actors (State-Sponsored Attackers)
Definition: Nation-state actors are government-backed hackers who conduct cyber-espionage, sabotage, or warfare.
Motivations:
- Espionage – Stealing classified intelligence from other nations.
- Disruption – Attacking critical infrastructure (power grids, financial systems).
- Political manipulation – Spreading disinformation to influence elections.
Techniques Used:
- Zero-day exploits – Exploiting unknown vulnerabilities before vendors patch them.
- Supply chain attacks – Compromising software vendors to infiltrate targets.
- Sophisticated malware – Custom-built trojans, rootkits, and backdoors.
Example:
The Stuxnet worm, allegedly developed by the U.S. and Israel, was designed to sabotage Iran’s nuclear facilities by disrupting industrial control systems.
Threat Level: Very High (Advanced resources, long-term strategies).
6. Advanced Persistent Threats (APTs)
Definition: APTs are highly skilled, organized groups that execute long-term, stealthy cyberattacks against targeted organizations, often linked to nation-states or sophisticated cybercriminal groups.
Motivations:
- Long-term espionage – Gaining persistent access to sensitive information.
- Stealthy sabotage – Undetectable manipulation of critical systems.
- Economic disruption – Damaging financial markets or corporate rivals.
Techniques Used:
- Multi-stage attacks – Gaining footholds, escalating privileges, and exfiltrating data.
- Polymorphic malware – Adapting to avoid detection.
- Fileless attacks – Leveraging legitimate processes to avoid leaving traces.
Example:
APT29 (Cozy Bear), believed to be linked to Russian intelligence, conducted cyber-espionage campaigns targeting government agencies and research institutions.
Threat Level: Critical (Extremely persistent, resourceful, and dangerous).
Comparison of Threat Actors
| Threat Actor | Motivation | Common Targets | Attack Methods | Threat Level |
|---|---|---|---|---|
| Script Kiddies | Fun, bragging rights | Websites, gaming servers | DDoS, website defacement | Low to Moderate |
| Hacktivists | Political/ideological | Governments, corporations | Doxing, DDoS, defacement | Moderate to High |
| Cybercriminals | Financial gain | Individuals, businesses | Phishing, ransomware | High |
| Insider Threats | Revenge, negligence | Employers, competitors | Data theft, sabotage | High |
| Nation-State | Espionage, disruption | Governments, industries | Zero-days, malware | Very High |
| APTs | Long-term access | Critical infrastructure | Fileless malware, stealth | Critical |
Conclusion
Threat actors vary in skill level, motivations, and attack methods, ranging from amateur hackers to sophisticated nation-state-sponsored attackers. Understanding their tactics enables organizations to develop proactive defense strategies and mitigate cyber risks effectively.
