A cyber attack refers to a deliberate and malicious attempt to breach the security of computer systems, networks, or digital devices, with the intention of stealing, altering, or destroying data, disrupting operations, or causing harm to individuals or organizations. Cyber attacks can take various forms, including but not limited to:
1. Malware Attacks: These involve the use of malicious software, such as viruses, worms, Trojans, ransomware, or spyware, to gain unauthorized access or control over a system.
2. Phishing Attacks: In this type of attack, cybercriminals send deceptive emails or messages to trick individuals into revealing sensitive information, such as passwords, credit card details, or social security numbers.
3. Denial-of-Service (DoS) Attacks: These attacks aim to overwhelm a system or network with a flood of traffic, rendering it inaccessible to legitimate users.
4. Man-in-the-Middle (MitM) Attacks: In a MitM attack, an attacker intercepts and alters communication between two parties without their knowledge, allowing them to eavesdrop, steal information, or manipulate data.
5. SQL Injection Attacks: This type of attack exploits vulnerabilities in a website or application's database by injecting malicious SQL code, potentially allowing unauthorized access or manipulation of data.
6. Advanced Persistent Threats (APTs): APTs are sophisticated and targeted attacks that involve a prolonged and stealthy infiltration of a network or system, often carried out by state-sponsored actors or highly skilled hackers.
7. Social Engineering Attacks: These attacks exploit human psychology and manipulate individuals into divulging sensitive information or performing actions that compromise security.
