Frontier: [Skills] 'Explain this presentation' built in skill in PPT Copilot (Web)

🚨 The Signal: PowerPoint Copilot for Web gains an 'Explain this presentation' skill, summarising entire decks. This feature can expose sensitive information if not properly governed, increasing data spill risk.

The Impact

Users with Copilot licenses are affected, increasing the risk of inadvertent sensitive data disclosure.

• End users: Risk of over-reliance on AI summaries, potentially missing critical details.
• Security team: Increased risk of sensitive data exposure through AI processing.
• Data owners: Potential for unauthorised summarisation of restricted content.
• Compliance officers: Challenges in auditing AI-generated summaries for data integrity.

The Action

1. Review and enforce Microsoft Purview Data Loss Prevention (DLP) policies for Copilot interactions.
2. Implement sensitivity labels for presentations containing sensitive information via Microsoft Purview.
3. Educate users on responsible AI use, emphasising not to summarise highly sensitive data.
4. Monitor Copilot usage logs for unusual activity or summarisation of restricted content.
