Understanding Phishing Attacks

What is Phishing?

Phishing is a cyber attack method where criminals impersonate legitimate organizations or individuals to trick victims into revealing personal information. These attacks often involve emails, websites, or messages that appear authentic but are designed to harvest your sensitive data.

Common Characteristics of Phishing Emails:

  • Unfamiliar sender addresses
  • Urgent or alarming content
  • Requests for personal information

Examples of Phishing Scenarios:

  • A message from a “colleague” requesting passwords or confidential information

Types of Phishing Attacks

Email Phishing: The most common type, where attackers send mass emails hoping to trick some recipients.

Spear Phishing: Targeted attacks on specific individuals, often based on previous research about the victim, making the attempt more convincing.

Whaling: A form of spear phishing aimed at high-profile individuals like executives or celebrities.

Rise in Phishing During Pandemics: Many attackers exploit crises, such as a global pandemic, by sending messages about health updates or financial relief.

Usage of Social Media for Phishing: Attackers use social media platforms to gather information and spread phishing links.

Phishing via Mobile Devices: Increasingly, phishing attacks are being tailored for mobile users, taking advantage of smaller screens and busy lifestyles.
