Cyber threats refer to malicious activities that target or exploit computer systems, networks, and digital devices. These threats are typically aimed at stealing data, disrupting operations, damaging digital assets, or gaining unauthorized access to sensitive information. Common types of cyber threats include:
1. Malware: Software designed to disrupt, damage, or gain unauthorized access to computer systems. Examples include viruses, ransomware, and spyware.
2. Phishing: Fraudulent attempts to trick users into revealing personal information, such as passwords or credit card numbers, often through deceptive emails or websites.
3. DDoS Attacks: Distributed Denial-of-Service attacks flood a network or website with excessive traffic to make it unavailable to users.
4. Man-in-the-Middle (MitM) Attacks: When attackers intercept and potentially alter the communication between two parties to steal data or inject malicious code.
5. SQL Injection: A technique where attackers insert malicious code into a database query to access or manipulate the database.
6. Zero-Day Exploits: Attacks that target software vulnerabilities that are unknown to the software developer or vendor.
7. Insider Threats: When someone within an organization, such as an employee or contractor, intentionally or unintentionally compromises security.
Cyber threats can come from various actors, including individual hackers, organized crime groups, and even nation-states. These threats pose significant risks to both individuals and organizations, necessitating robust cybersecurity measures to detect and prevent them.
