Introduction to Phishing Attacks
Phishing attacks are a prevalent form of cybercrime where attackers impersonate legitimate entities to deceive individuals into revealing sensitive information. These attacks can lead to unauthorized access to personal data, financial loss, and compromised security.
Understanding the mechanisms of phishing attacks is crucial for individuals and organizations to implement effective preventive measures. This guide delves into the various types of phishing attacks, their indicators, and strategies to safeguard against them.
Common Types of Phishing Attacks
