Which network attack refers to sending huge volumes of email to an address in an attempt to overflow the mailbox, or overwhelm the server where the email address is hosted, to cause a denial-of-service attack?

• A. Email spamming
• B. Mail bombing
• C. Phishing
• D. Email spoofing

Answer: (B)

Flooding a mailbox or mail server with an enormous number of emails is a denial-of-service technique known as mail bombing. By inundating the target with messages, the mailbox fills up or the mail processor becomes overloaded, causing legitimate emails to be delayed or rejected. This intentional overflow disrupts normal email service and can cause downtime for the target. This is distinct from general spam, which is bulk emailing for advertising and may not aim to crash a specific mailbox or server. Phishing focuses on deceiving users to reveal sensitive information, while email spoofing forges the sender’s identity. Mail bombing specifically targets service availability by overwhelming the system with volume. Defense includes mailbox quotas, rate limiting, robust filtering, and monitoring for spikes in inbound mail.
