4. Distributed Denial of Service (DDoS) Attacks: In DDoS attacks, a network of compromised computers (botnet) overwhelms a target server or network with a flood of traffic, causing it to become unavailable to legitimate users.

5. Man-in-the-Middle (MitM) Attacks: In MitM attacks, an attacker intercepts and potentially alters communications between two parties without their knowledge. This can lead to data theft and unauthorized access.

6. SQL Injection: This is a type of attack where attackers insert malicious SQL queries into web forms or input fields. If successful, they can gain access to a database or manipulate data.

7. Zero-Day Vulnerabilities: Zero-day vulnerabilities are security flaws in software or hardware that are unknown to the developer or vendor. Attackers exploit these vulnerabilities before they can be patched.

8. Insider Threats: Insider threats come from individuals within an organization who misuse their access privileges to compromise security. This can be intentional or unintentional.

9. Social Engineering: Social engineering attacks rely on manipulating people into divulging confidential information or performing actions that compromise security. This includes techniques like pretexting and baiting.

10. IoT Vulnerabilities: Internet of Things (IoT) devices often have weak security, making them vulnerable to attacks. Compromised IoT devices can be used to gain access to the broader network.

11. Credential Theft: Attackers use various methods to steal usernames and passwords, such as brute force attacks, keyloggers, and credential stuffing.

12. Data Breaches: Data breaches involve unauthorized access to sensitive data, which can result in data theft, identity theft, and financial loss. Breaches can occur due to vulnerabilities or human errors.

13. Malicious Code Execution: Attackers can execute malicious code on a victim's system, leading to unauthorized access, data theft, or system compromise.

14. Cryptojacking: Cryptojacking involves using a victim's computer or device to mine cryptocurrencies without their consent, consuming system resources, and slowing down the device.

15. Advanced Persistent Threats (APTs): APTs are long-term, highly targeted attacks by skilled adversaries, often sponsored by nation-states. They are designed to remain undetected and can lead to significant data theft or espionage.

To protect against these cybersecurity threats, individuals and organizations must implement security best practices, regularly update software and systems, use strong and unique passwords, and stay informed about emerging threats and vulnerabilities.
