This detection rule identifies messages that include 'risky-recover-production' within the message ID header, which serves as an indicator of potentially suspicious or malicious activities. The rule is particularly valuable in combating spam and recognizing evasion techniques that attackers may use to disguise their communications. By employing header analysis, the rule filters inbound messages and flags any that contain the defined string, allowing security teams to investigate further. This proactive measure aims to enhance the organization’s email security posture, ensuring that unusual patterns in message exchanges are closely monitored and addressed promptly.
