By implementing proactive measures and staying vigilant, you can safeguard your valuable assets and navigate the ever-changing threat landscape with confidence. To help you get started, this blog delves into the nature of cyber threat actors, explores their prevalent techniques, and offers actionable insights to bolster your organisation’s security posture.
What is a Cyber Threat Actor?
A cyber threat actor is an individual or group that targets vulnerabilities in digital systems and networks with malicious intent. Their objectives often include stealing confidential information, causing financial damage, or disrupting services.
They use various techniques, such as ransomware, phishing, and credential stuffing, to achieve these goals. Due to their focus on digital environments, cyber threat actors employ sophisticated methods, requiring advanced strategies to effectively counter their ever-evolving threats.
What is the difference between a Threat Actor and a Cyber Threat Actor?
A threat actor is any individual or group that engages in malicious activities with the intent to cause harm or gain an advantage. In contrast, a cyber threat actor operates specifically within the digital realm, targeting computer systems, networks, and data. While threat actors can encompass a range of malicious entities involved in physical sabotage or espionage, cyber threat actors focus solely on exploiting vulnerabilities in digital systems.
This distinction underscores the specialised nature of cyber threat actors, who use techniques such as hacking, malware distribution, and phishing to compromise IT infrastructure, whereas general threat actors might employ a broader array of tactics across various domains.
What are the most common types of Cyber Threat Actors?
The 8 most common types of cyber threat actors are:
- Career cybercriminals
- Nation-state actors
- Hacktivists
- Insider threats
- Script kiddies
- Cyber terrorists
- Thrill seekers
- Organised crime groups
1. Career Cybercriminals
Career cybercriminals are among the most prevalent types of threat actors, driven primarily by financial motives. These individuals or groups exploit vulnerabilities in digital systems to steal sensitive information, commit fraud, or carry out ransomware attacks.
Their methods often involve phishing, data breaches, and malware, which enable them to extort businesses, institutions, and individuals. Constantly evolving, these cybercriminals refine their tactics to avoid detection, ensuring they remain effective and profitable in their illicit activities.
2. Nation-State Actors
Nation-state actors are government-backed entities that pursue political, economic, or military objectives through cyberattacks. They typically target government agencies, critical infrastructure, and large corporations, focusing on espionage and data theft. Unlike financially motivated cybercriminals, these actors employ advanced techniques and maintain persistent access, making them difficult to detect and trace.
3. Hacktivists
Hacktivists are cybercriminals motivated by ideological, political, or social causes rather than financial gain. They seek to advance their agendas, challenge perceived injustices, or sway public opinion.
Unlike traditional cybercriminals who pursue monetary rewards, hacktivists focus on high-profile targets, using methods such as defacing websites, leaking sensitive data, or disrupting services. Their goal is to attract attention to their causes, often achieving significant impact by amplifying their message and gaining widespread visibility.
4. Insider Threats
Insider threats are posed by individuals within an organisation, including employees, third-party contractors, or partners, who misuse their access to systems, data, or information for personal gain, data theft, sabotage, or espionage. Unlike external attackers, insiders have legitimate access, which makes their actions more challenging to detect.
5. Script Kiddies
Script kiddies are inexperienced hackers who rely on publicly available tools and pre-written scripts, often developed by more skilled cybercriminals, to execute attacks. Despite their limited technical knowledge, they can still cause significant harm by exploiting known vulnerabilities in poorly secured systems.
Motivated by curiosity, disruption, or a desire for recognition, their attacks, though generally unsophisticated, can result in serious breaches, particularly for smaller businesses with outdated defences.
6. Cyber Terrorists
Cyber terrorists launch digital attacks to advance political or ideological goals, aiming to create fear and widespread disruption. By targeting critical infrastructure such as power grids and government systems, they seek to destabilise nations and incite panic.
Unlike financially driven hackers, their primary goal is to cause chaos and undermine public trust, making them one of today’s most dangerous cyber threats.
7. Thrill Seekers
Thrill seekers are driven by excitement and challenge rather than financial gain or ideology. They hack for the adrenaline rush or to demonstrate their skills. While their motives may appear less malicious, their actions can still cause significant damage.
With no clear objectives, their unpredictable behaviour poses a risk to anyone unprepared for these impulsive attacks.
8. Organised Crime Groups
Organised crime groups are a significant cyber threat, motivated by financial gain. They employ a range of sophisticated techniques, including developing and selling ransomware and malware. They also profit from selling stolen data, such as credentials, bank account details, and social security numbers.
Additionally, they commit fraud using this stolen data for identity theft, financial fraud, and account takeovers. Their well-funded and coordinated operations make their attacks highly targeted and capable of causing substantial damage.
What techniques and tactics do Cyber Threat Actors use?
Malware
Malware is malicious software designed to damage or disrupt computers and network resources. It manifests in various forms, such as trojans, worms, stealers, rootkits, cryptojacking tools, keyloggers, and ransomware. Each type enables cyber threat actors to infiltrate systems, steal data, or inflict other damage.
Ransomware
Ransomware is a form of malicious software that locks a victim’s files and demands a payment to restore access. Extortionist ransomware intensifies this threat by threatening to publish or release stolen data to force payment.
Social Engineering
Threat actors often employ social engineering tactics to gain initial access to networks or resources by exploiting human vulnerabilities. These methods manipulate individuals into disclosing sensitive information or taking actions that jeopardise security.A common approach is phishing, where attackers send deceptive communications, such as emails, that seem to come from legitimate sources. Their aim is to trick recipients into revealing credentials or providing access, thus compromising the IT infrastructure.
Cloud
Threat actors often exploit common vulnerabilities and misconfigurations in cloud resources soon after they are disclosed. After gaining access, they may exfiltrate data for sale on illicit marketplaces or move laterally within the cloud environment to expand their reach.
DDoS
A Distributed Denial of Service (DDoS) attack overwhelms a server, service, or network by flooding it with excessive internet traffic from multiple compromised systems. This approach interrupts regular activities and can render the target inaccessible to authorised users.
Besides causing disruptions, DDoS attacks can also serve as a smokescreen, allowing attackers to steal data or exploit other vulnerabilities.
Third-party
Threat actors frequently target third-party software or technology providers to reach a broader network of customers. By compromising managed service providers, cloud service providers, and other IT services that are embedded in corporate environments and handle organisational data, attackers can gain access to multiple downstream systems and data sets, amplifying the impact of their attacks.
Brute Force and Credential Stuffing
Brute forcing involves attempting all possible combinations to crack passwords, while credential stuffing uses stolen password lists to gain access to accounts. Both methods are commonly grouped under the term “brute forcing.” Variations include reverse brute forcing, where a single common password is tested against many usernames, and the use of automated tools to try multiple combinations simultaneously.
How can your organisation protect against Cyber Threat Actors?
To effectively defend against cyber threat actors, organisations must focus on both proactive measures and ongoing vigilance. Establishing comprehensive security policies and providing regular training for employees to recognise threats like phishing and social engineering is essential.
Human error often serves as a key vulnerability, and a well-informed workforce can significantly lower the risk of such attacks. Alongside this, deploying and maintaining advanced security technologies, such as firewalls, threat detection solutions, and anti-malware tools, is critical. Ensuring these tools are consistently updated and patched addresses known vulnerabilities that could be exploited by cybercriminals.
Moreover, continuous monitoring and analysis of network activity are vital for early detection of anomalies and potential breaches. Regular vulnerability assessments and penetration testing help uncover and fix weaknesses before they can be exploited. Implementing a robust incident response plan and maintaining secure backups ensure that organisations can quickly recover from attacks and minimise damage.
