Phishing is a technique used by cyber criminals to trick individuals into revealing their sensitive information, such as passwords or credit card details. Social engineering involves manipulating individuals to gain unauthorized access to systems or data.

1. Definition and examples of phishing

Phishing is a form of cyber attack where attackers impersonate legitimate entities, such as banks or online services, to trick individuals into revealing their personal information. This information can then be used for identity theft or other fraudulent activities. Examples of phishing include receiving an email that appears to be from a bank asking for account details or clicking on a link that leads to a fake login page.

2. Techniques used in social engineering attacks

Social engineering attacks rely on psychological manipulation to deceive individuals and gain unauthorized access to systems or data. These attacks can involve impersonation, pretexting, or baiting. The goal is to exploit human vulnerabilities rather than technical vulnerabilities.

3. Prevention and protection against phishing attacks

To protect against phishing attacks, individuals and organizations should be vigilant and follow best practices. This includes being cautious of suspicious emails or messages, verifying the authenticity of websites before entering sensitive information, and regularly updating passwords.

D. Malware and Ransomware

Malware refers to malicious software that is designed to disrupt computer systems, steal data, or gain unauthorized access. Ransomware is a specific type of malware that encrypts files and demands a ransom for their release.

1. Definition and examples of malware

Malware is a broad term that encompasses various types of malicious software, including viruses, worms, trojans, and spyware. These programs can be designed to steal sensitive information, disrupt computer systems, or gain unauthorized access. Examples of malware include a virus that deletes files on a computer or spyware that monitors a user's online activities.

2. How ransomware works and its impact

Ransomware is a type of malware that encrypts files on a victim's computer or network, making them inaccessible. The attacker then demands a ransom, usually in the form of cryptocurrency, in exchange for the decryption key. Ransomware attacks can have severe consequences, including financial losses, data breaches, and disruption of services.

3. Measures to prevent malware and ransomware attacks

Preventing malware and ransomware attacks requires a combination of technical measures and user awareness. This includes installing and regularly updating antivirus software, being cautious of downloading files or clicking on suspicious links, and regularly backing up important data.
