What term describes a scenario where a large volume of junk email is sent automatically without human involvement?

The term that best describes a scenario where a large volume of junk email is sent automatically without human involvement is "mail bombing." This refers to a deliberate action where an overwhelming number of emails are sent to a specific email address, often with the intent to disrupt services or overwhelm the recipient's inbox. This can lead to various issues such as account lockouts, server slowdowns, or denial of service for legitimate users.

While "mail storming" might suggest a similar concept of many emails being sent, it is not the established terminology used in the field of cybersecurity or incident handling. "Identity theft" relates to unauthorized use of someone's personal information, which is not relevant to the email scenario described. "Malware distribution" involves sending malicious software, which is a different form of cyber threat than the mass sending of irrelevant or unwanted emails.

Understanding the correct terminology helps in recognizing and addressing specific types of cyber incidents effectively.
