So what are Phishing emails?

Phishing is a type of cyber attack where malicious actors impersonate legitimate entities, such as banks, government agencies, or reputable companies, in order to deceive individuals into providing sensitive information like passwords, credit card numbers, or personal data.
This is typically done through deceptive emails, text messages, or websites that appear authentic but are actually designed to trick recipients into divulging confidential information. Phishing attacks often exploit human psychology, relying on urgency, fear, or curiosity to manipulate victims into taking actions that compromise their security.
Phishing poses a significant threat to individuals and businesses alike, as falling victim to these attacks can result in identity theft, financial loss, or unauthorized access to sensitive data. Vigilance, education, and the use of security measures like anti-phishing software are crucial in combating this pervasive threat.
