Spear Phishing: Definition, Examples, Prevention & How It Works in 2026
Spear phishing is a highly targeted cyberattack where attackers impersonate trusted sources to trick specific individuals or organizations into revealing sensitive information, clicking malicious links, or installing malware. Unlike generic phishing, spear phishing relies on detailed research—using sources like LinkedIn, company websites, and social media—to craft personalized and convincing messages. Attackers exploit psychological tactics such as urgency, authority, and familiarity to increase the chances of success. These attacks often target employees with access to financial systems, sensitive data, or privileged accounts. Once the victim interacts with the malicious content, attackers can steal credentials, gain network access, or conduct fraud. Spear phishing is more successful and costly than standard phishing because of its precision and realism. Preventing it requires vigilance, verifying unusual requests, and using phishing-resistant authentication methods like passkeys or security keys.
