Email flood is a type of cyberattack in which a malicious actor sends a large number of emails to a specific email address or server in order to overwhelm it and prevent legitimate users from accessing their accounts or using the service. Email floods can be used to disrupt businesses, organizations, and individuals, and can cause significant financial and reputational damage.
Email floods are often used in conjunction with other types of cyberattacks, such as phishing and malware attacks. By overwhelming a target with a large number of emails, attackers can make it more difficult for users to identify and respond to legitimate emails, increasing the chances that they will click on malicious links or open attachments that contain malware.
