2. Organized Crime Syndicates: Many cyberattacks are executed by large, well-funded organized crime groups that operate across borders, utilizing specialized roles (e.g., malware developers, phishers, money mules) and employing sophisticated tactics.
3. State-Sponsored Hacking: Nation-states engage in cyber warfare for espionage, intellectual property theft, political disruption, or to target critical infrastructure. These attacks are often highly advanced and persistent (Advanced Persistent Threats – APTs).
4. Hacktivism: Groups or individuals use hacking to promote a political or social agenda, often through website defacement, denial-of-service attacks, or data leaks (e.g., Anonymous).
5. Insider Threats: Disgruntled employees or individuals with legitimate access can pose significant risks by intentionally or unintentionally compromising data or systems from within an organization.

B. Common Cyber Threats and Attack Vectors

Understanding how these malicious actors operate involves recognizing the most prevalent types of cyber threats.

1. Malware (Malicious Software): A broad category of software designed to cause damage, gain unauthorized access, or disrupt operations.
   • Viruses: Attach themselves to legitimate programs and spread when the program is executed.
   • Worms: Self-replicating malware that spreads across networks without human intervention.
   • Trojans: Disguise themselves as legitimate software to trick users into installing them, then provide backdoors for attackers.
   • Ransomware: Encrypts a victim’s files, demanding a ransom (usually cryptocurrency) for decryption. Its impact is often devastating, crippling businesses and even public services.
   • Spyware: Secretly monitors and collects user information (e.g., Browse history, keystrokes) without their knowledge.
   • Adware: Displays unwanted advertisements, often bundled with free software.
2. Phishing and Social Engineering: Manipulating people into divulging confidential information or performing actions they wouldn’t normally do.
   • Phishing: Deceptive emails, messages, or websites designed to trick recipients into revealing sensitive data (e.g., login credentials, credit card numbers) by impersonating trusted entities.
