Phishing: Recognizing and preventing cyber threats
Phishing is a social engineering attack in which cybercriminals trick individuals into revealing sensitive information, installing malware, or transferring money. These attacks are typically carried out through emails, messages, or fake websites that appear to come from trusted sources.
It is one of the most common cyber threats, targeting both individuals and organizations. To protect personal data and financial assets, it is essential to recognize phishing tactics and implement security measures.
How does phishing work?
Phishing attacks exploit human trust to deceive victims into taking actions that compromise their security.
Common techniques
- Email phishing – Attackers send emails impersonating legitimate organizations (e.g., banks, service providers) to steal login credentials.
- Spear phishing – A highly targeted attack customized for a specific individual, often using personal details.
- Whaling – A phishing attack aimed at executives or high-ranking officials within an organization.
- Smishing (via SMS) – Fraudulent text messages urging recipients to click malicious links.
- Vishing (via voice) – Phone calls from scammers pretending to be from trusted companies or authorities.
Signs of a phishing attempt
- Unexpected emails requesting urgent action (e.g., “Your account will be locked in 24 hours!”).
- Suspicious links or attachments containing malware.
- Emails with spelling mistakes, unusual formatting, or generic greetings (e.g., “Dear Customer”).
- Requests for login credentials, payment information, or personal details.

How to prevent phishing attacks and protect personal data
Organizations and individuals must take proactive measures to detect and prevent phishing attempts.
1. Verify sender identity and avoid suspicious links
- Check the email address carefully—attackers often use slightly altered domain names.
- Hover over links before clicking to see if they lead to a legitimate website.
2. Enable multi-factor authentication (MFA)
- Even if login credentials are stolen, MFA adds an extra layer of security.
- Use authentication apps instead of SMS-based verification where possible.
