Phishing is a malicious cyber attack in which attackers use deceptive tactics to trick individuals into revealing sensitive information, such as login credentials, financial data, or personal details. This social engineering technique targets human vulnerability rather than technical vulnerabilities, making it a prevalent and effective method used by cybercriminals to gain unauthorized access to valuable information. Recognizing and defending against phishing attacks are essential for safeguarding personal and organizational data and preventing financial losses and identity theft.
Phishing attacks rely on exploiting the trust that people have with legitimate organizations and/or contatcs. Cybercriminals craft messages that appear to be from a legitimate source and include deceptive links or attachments. When clicked or opened, these links or attachments can install malware or ransomware, or trick people into revealing sensitive information such as usernames, passwords, and credit card numbers.
5 Most Common Types of Phishing Attacks
- Email Phishing: Attackers send deceptive emails, often posing as legitimate entities like banks, social media platforms, or reputable organizations, to lure recipients into clicking malicious links or downloading harmful attachments.
- Spear Phishing: More targeted than regular phishing, spear phishing tailors the attack to a specific individual or organization, leveraging personal information to appear more convincing.
- Whaling: Targeting high-profile individuals, such as CEOs or executives, whaling aims to steal sensitive business information and gain access to critical systems.
- Vishing (Voice Phishing): Using phone calls or voicemail messages, vishing attempts to trick individuals into disclosing personal information or performing specific actions.
- Smishing (SMS Phishing): Phishing attacks conducted through text messages, smishing aims to deceive recipients into clicking malicious links or providing sensitive data.
How to Identify a Phishing Attack
