What Is Phishing?

Definition: Phishing

Phishing is a cyber attack that uses disguised email as a weapon. The goal is to trick the email recipient into believing that the message is something they want or need — a request from their bank, for instance, or a note from someone in their company — and to click a link or download an attachment.

Understanding Phishing

Phishing is one of the oldest types of cyberattacks, dating back to the 1990s, and it’s still one of the most widespread and pernicious, with phishing messages and techniques becoming increasingly sophisticated.

The Evolution of Phishing

Originally, phishing scams were largely carried out via email. However, with the evolution of technology and the proliferation of social media platforms, phishing attacks have found new avenues, including SMS (Smishing), voice calls (Vishing), and even social media platforms. These attacks often leverage current events, crises, or popular trends to increase their success rates.

Types of Phishing Attacks

• Spear Phishing: Targets a specific individual or organization with tailored messages.
• Whaling: A type of spear phishing that targets senior executives and other high-profile targets.
• Clone Phishing: Involves creating a nearly identical replica of a legitimate message previously sent, but with malicious links or attachments.
• Pharming: Redirects users from legitimate websites to fraudulent ones for the purpose of extracting confidential data.

How Phishing Works

1. Initial Contact: The attacker sends out a fraudulent message that appears to be from a trusted source. This can be via email, social media, SMS, or any electronic communication channel.
2. Lure: The message includes a lure, often in the form of an urgent or enticing request, to provoke the recipient into action.
3. Deception: The recipient is deceived into clicking a malicious link, downloading a malicious file, or providing sensitive information under the guise of necessity.
4. Exploitation: Once the action is taken, the attacker can exploit the access or information for malicious purposes, such as stealing identities, funds, or sensitive data.

Mitigating Phishing Attacks

Protecting against phishing requires awareness, education, and the use of technology:

• Education and Awareness: Regular training and awareness programs can help users recognize and avoid phishing attempts.
• Email Filters: Advanced email filtering solutions can detect and quarantine phishing emails before they reach the inbox.
• Multi-Factor Authentication (MFA): Even if credentials are compromised, MFA can provide an additional layer of security.
• Regular Updates and Patches: Keeping systems and security software updated can help protect against known vulnerabilities that phishing attempts may exploit.
