This detection rule identifies potential exploitation of the Foxmail client, an email application, which may occur through vulnerable processes initiated by malicious emails. The rule focuses on Child Process Creation events where Foxmail spawns other processes that point to its temporary directory, which can indicate a successful exploitation attempt. Specifically, it looks for events where the parent process is 'Foxmail.exe' and gathers additional details through arguments suggesting access to user-specific AppData directories. This allows security teams to ascertain whether an attacker is leveraging Foxmail vulnerabilities to gain unauthorized access to systems through crafted emails that lead to malicious payload execution. The rule integrates multiple data sources such as Windows Event Logs, Sysmon logs, Crowdstrike, and Microsoft Defender, aiding in a comprehensive analysis of process creation events for threat detection and response. Additionally, it outlines possible investigation steps and actions for false positives, reinforcing the importance of thorough validation and contextual analysis when dealing with alerts.
