An email subscription bomb is a malicious tactic where an individual uses a script or program to bombard a target email address with a massive number of subscription requests, overwhelming the recipient’s inbox and causing significant disruption.
This technique is often employed as a form of cyberbullying or harassment, or to disrupt the operations of an organization by flooding its email servers with excessive traffic. Email subscription bombs can also be utilized in phishing scams to trick recipients into providing sensitive information. Historically, this tactic has been used for political activism and to target specific individuals or groups.
