The following analytic detects the suspicious auditd service stop. This behavior is critical for a SOC to monitor because it may indicate attempts to gain unauthorized access or maintain control over a system. Such actions could be signs of malicious activity. If confirmed, this could lead to serious consequences, including a compromised system, unauthorized access to sensitive data, or even a wider breach affecting the entire network. Detecting and responding to these signs early is essential to prevent potential security incidents.

This query was originally published in the threat analytics report, Windows 7 zero-day for CVE-2019-0808
CVE-2019-0808 is a vulnerability that allows an attacker to escape the Windows security sandbox and run arbitrary code with admin privileges. This vulnerability affects Windows 7, Windows Server 2008, and Windows Server 2008 R2.
Exploits for CVE-2019-0808 were first observed as part of highly selective attacks using the Nufsys backdoor. Although the Nufsys-associated exploit was first described as a zero-day, the issue has since been patched.
The following query detects possible CVE-2019-0808 exploitation by reporting network communication associated with the Nufsys attacks.
