The Spam Email Surge detection rule aims to identify potential spam email attacks targeting individual users in GSuite. By monitoring the number of spam emails received by a user within a specified short timeframe, this rule helps to determine if the user may have been compromised or targeted based on leaks or exposure of their email address. The rule triggers an alert when a user receives more than 20 spam emails in a 60-minute period. The detection leverages GSuite activity event logs to analyze email delivery occurrences that are marked as spam, assessing various attributes such as the sending IP address, message subject, and other relevant log information. It is critical for identifying trends that indicate abuse and potentially malicious outcomes related to certain email accounts, thereby enabling rapid incident response and user protection against phishing tactics and spamming campaigns.
