6 Types of Cyber Adversaries



1. Nation-State Attackers (APTs)

Nation-state attackers, driven by political motives and espionage, target governments, critical infrastructure, defense, technology, and research sectors.

Examples

• Stuxnet: A sophisticated computer worm discovered in 2010 that targeted Iran's nuclear program. It's believed to be a nation-state attack, likely a joint effort, that used multiple zero-day exploits to infect programmable logic controllers (PLCs), causing the centrifuges to malfunction.
• Hafnium: A series of zero-day exploits targeting Microsoft Exchange servers discovered in early 2021. Attributed to a Chinese state-sponsored hacking group, Hafnium allowed attackers to access email accounts, install backdoors, and steal data from numerous organizations worldwide.

Tactics

These well-resourced groups, often operating within government structures, leverage secure communication channels. In addition to custom malware, nation-state attackers aiming for military, economic, or political gain use a variety of techniques, such as:

• APTs: Sophisticated, stealthy cyberattacks that aim for long-term infiltration and data exfiltration rather than quick, smash-and-grab attacks. They are designed to remain undetected for extended periods of time.
• Spear phishing: Highly targeted form of social engineering attack using crafted emails or messages that appear to be from trusted sources. While traditional phishing casts a wide net, spear phishing focuses on specific individuals or organizations.
• Zero-day exploits: Take advantage of previously unknown vulnerabilities in software or hardware. These vulnerabilities are called "zero-day" because the software vendor or developer has zero days to patch the flaw before it's exploited.



Defense Strategies

• Advanced network monitoring: Continuous, real-time monitoring of network activity to detect anomalous behavior, suspicious traffic patterns, and indicators of compromise (IOCs) that might suggest an ongoing or imminent attack
• Layered security: This approach assumes that no single solution is foolproof and implements multiple layers of security controls to protect assets.
• Threat intelligence sharing: The exchange of information about cyber threats between organizations, industries, and even governments. This shared information can include IOCs, TTPs, and information about specific threat actors.

2. Cybercriminals

Cybercriminals, driven by financial gain, target organizations holding valuable data (like banks and retailers) as well as individuals with weak passwords and compromised accounts.

Tactics and Examples

Cybercriminals work alone or in groups, using underground forums and dark web marketplaces to implement various cyberattacks, including:

• Phishing: A social engineering strategy that attempts to obtain sensitive information (usernames, passwords, & credit card details) by masquerading as a trustworthy entity (bank, social media site, coworker, etc.).
• Ransomware: A type of malware that encrypts a victim's files or blocks access to their computer system, demanding a ransom payment to restore access.
• Trojans: Malicious software disguised as legitimate programs that trick users into downloading or installing them, unknowingly infecting their systems.
• DDoS attacks: An attack that floods a target website or network with traffic and overwhelms the target's resources, making it unavailable to legitimate users.



Defense Strategies

• Firewalls and antivirus software: These act as barriers between your network and the outside world (or between different parts of your network), blocking unauthorized access, detecting and removing malware, and scanning files, programs, and network traffic continuously.
• Regular backups and updates: Installing security patches and updates for your operating systems, applications, and hardware is essential to fixing known vulnerabilities before they are exploited. Creating copies of your important data and storing them separately can help mitigate the fallout of a ransomware attack or data loss.
• Security training: Educating employees and users about cybersecurity best practices, especially for popular attack methods like phishing and other social engineering tactics, is essential. Training should cover topics like password security, safe browsing habits, and how to identify suspicious emails and other contact points.
• Incident response plans: A documented set of procedures that an organization follows when a cybersecurity incident occurs. The plan should outline roles and responsibilities, communication protocols, steps for containing the incident, and procedures for recovery.

3. Hacktivists

Hacktivists are motivated by political, social, or religious beliefs, targeting governments, corporations, and organizations considered unjust. Their aim is to promote their ideals, destabilize the supposed oppressors, and raise awareness.

Tactics and Examples

These decentralized groups often take advantage of existing tools coordinated through social networks to achieve maximum impact. In addition to DDoS attacks, other common tactics include:

• Website defacement: Exploiting vulnerabilities in a target website to replace the existing content with messages, images, or videos that promote their cause or criticize the target.
• Data leaks (doxing): Releasing confidential or sensitive information to the public. This can include personal details, internal documents, emails, or financial records.
• Anonymous attacks: Defamatory cyberattacks carried out with the goal of maintaining anonymity. Hacktivists often use tools and techniques (proxy servers, VPNs, etc.) to mask their identities and locations, making it difficult to trace the attack back to them.

Defense Strategies

• Monitoring online activity: Actively monitoring online platforms, social media, and forums (by tracking hashtags and keywords) for mentions of your organization, discussions about potential attacks, or leaked information. Additionally, consider using social listening tools and cyber threat intelligence platforms like KELA.
• Robust system maintenance: Regularly patching vulnerabilities, updating software, and performing security audits to ensure that systems are secure and up-to-date.

4. Terrorist Groups

Terrorist groups leverage online platforms to advance political or social agendas through intimidation and fear, similar to hacktivists.

Tactics and Examples

Terrorist groups target governments, militaries, critical infrastructure, and symbolic organizations. Their tactics include DDoS attacks, defacement, doxing, and hit lists, often spread through social media. They use the internet for recruiting, training, and planning attacks by communicating through social networks and encrypted channels

Examples include:

• Airport website defacement
• Military information dissemination
• Online recruitment



Defense Strategies

In addition to monitoring social media and other online activity, proactive strategies include:

• Employee threat identification training: Training employees to recognize and report suspicious behavior, including potential signs of radicalization or involvement in cyber terrorist activities. Ensure clear reporting channels and written procedures for employees to follow.
• Collaboration with authorities: Establishing and maintaining close working relationships with law enforcement agencies, intelligence communities, and other relevant authorities. This includes sharing threat information, coordinating incident response efforts, and participating in joint exercises.

5. Insiders

Insider threats are those committed by individuals who are affiliated with, or work for, a particular organization. They can occur for a variety of reasons, including financial gain, ideological discontent, personal motives, or accidental mistakes.

Tactics and Examples

Insiders target industries that handle sensitive data, like finance, technology, healthcare, and government. They use legitimate credentials to access and steal data or intellectual property, install malware, exploit privileges, and manipulate others.

Their internal position grants them access to the system, and they may use internal or external channels for communication.

Defense Strategies

In addition to security training and regular audits, defensive strategies for insider threats include:

• Robust access controls: A set of security measures designed to restrict access to sensitive data and systems based on the principle of least privilege. This means that users are only granted the minimum level of access necessary to perform their job duties, and goes hand in hand with tactics like multi-factor authentication (MFA).
• User activity monitoring: Monitoring and analyzing user behavior to detect anomalous activity that might indicate an insider threat. UAM systems track user logins, file access, data transfers, and other actions to establish a baseline of normal behavior.
