Microsoft Copilot (Microsoft 365): Language expansion coming in Microsoft 365 Copilot

🚨 The Signal: Microsoft Copilot will support six new languages, expanding its global reach. This broadens the attack surface for prompt injection and data exfiltration in new linguistic contexts, requiring vigilance in data governance and AI policy enforcement.

The Impact

Users in new language regions are affected, increasing the risk of prompt injection and data exfiltration.

• Security teams face increased risk of prompt injection attacks in new languages.
• Data owners must extend data loss prevention policies to new linguistic contexts.
• Compliance officers need to ensure AI usage policies cover new language users.
• Incident responders may see new types of incidents related to multilingual Copilot use.

The Action

1. Review and update Data Loss Prevention (DLP) policies to account for new languages in Copilot.
2. Communicate updated AI usage guidelines to users in newly supported language regions.
3. Monitor Copilot usage logs for unusual activity or potential prompt injection attempts in new languages.
4. Assess existing prompt engineering guidelines for applicability to new linguistic contexts.
