Detection rules for SIGRed vulnerability
Elastic Security released detection rules for CVE-2020-1350 (SIGRed), a critical remote code execution vulnerability in Windows DNS Server that was patched by Microsoft on July 14, 2020. The detection logic identifies suspicious child processes of dns.exe, abnormal file modifications by the DNS service, and unusually large DNS responses that could indicate exploitation attempts. Organizations can implement these rules using endpoint security, Winlogbeat, Packetbeat, or network security monitoring platforms such as Zeek or Suricata.
Why it matters: DNS administrators and security teams managing Windows DNS servers (2003 and later) need these detection rules to identify active exploitation attempts, especially for systems that cannot be immediately patched. The vulnerability affects domain controllers and member servers relying on Active Directory and Kerberos, which could enable lateral movement and domain compromise.
