Spear phishing is a highly targeted form of phishing attack where cybercriminals impersonate trusted individuals or organizations to deceive specific recipients. Unlike generic phishing, spear phishing uses personalized information to make fraudulent emails appear legitimate, increasing the likelihood that the victim will open malicious attachments or click on harmful links. These attacks often aim to steal sensitive data, such as login credentials or financial information, or to install malware on the victim's device. Spear phishing is a common tactic in both corporate and personal cyberattacks due to its effectiveness in bypassing standard security measures.
