4) What do we need to do to defend/detect/respond?

• Enhance email security to detect spear-phishing attempts, especially those with region-specific themes.
• Implement strict application whitelisting to prevent unauthorized ClickOnce executions.
• Monitor for unusual network activity, especially geofenced IP communications.
• Conduct regular threat hunting for indicators of compromise related to SideWinder activities.

5) What’s the potential business/regulatory exposure?

• Exposure includes potential data breaches affecting sensitive diplomatic communications.
