Phishing is a technique commonly executed via email, where attackers attempt to deceive employees into revealing sensitive information, such as their credentials, or trick them into installing malicious applications that grant the attackers control over the system.
Phishing is a prevalent tactic used by attackers to gain system access, and penetration testers can exploit it as well. By conducting multiple rounds of phishing campaigns, organizations can assess user awareness, the effectiveness of anti-spam filters, and the potential for threats from both external attackers and internal sources, including the security department.
