====== How to defend ourselves? ======

We can use MITRE Att&ck framework to asses defensive capability across your security architecture.

The MITRE ATT&K® framework helps provide context to the Sunburst campaign. The following represent known tactics and techniques:

  *        Query Registry [T1012]
  *        Obfuscated Files or Information [1027]
  *        Obfuscated Files or Information: Steganography [T1027.003]
  *        Process Discovery [T1057]
  *        Indicator Removal on Host: File Deletion [T1070.004]
  *        Application Layer Protocol: Web Protocols [T1071.001]
  *        Application Layer Protocol: DNS [T1071.004]
  *        File and Directory Discovery [T1083]
  *        Ingress Tool Transfer [T1105]
  *        Data Encoding: Standard Encoding [T1132.001]
  *        Supply Chain Compromise: Compromise Software Dependencies and Development Tools [ [T1195.001]
  *        Supply Chain Compromise: Compromise Software Supply Chain [T1195.002]
  *        Software Discovery [T1518]
  *        Software Discovery: Security Software Discovery [T1518.001]
  *        Create or Modify System Process: Windows Service [T1543.003]
  *        Subvert Trust Controls: Code Signing [T1553.002]
  *        Dynamic Resolution: Domain Generation Algorithms [T1568.002]
  *        System Services: Service Execution [T1569.002]
  *        Compromise Infrastructure [T1584]

====== Mitigation steps ======

  * Implementing multi factor authentication.
