Power Automate - Automate PowerPoint presentations in desktop flows

🚨 The Signal: Power Automate desktop flows can now automate PowerPoint, enabling programmatic creation and modification of presentations. This introduces new vectors for data manipulation and exfiltration via automated processes.

The Impact

Security teams and administrators are affected by new automation capabilities that could be misused for data exfiltration or integrity compromise.

• Security teams: Increased risk of data exfiltration via automated PowerPoint content.
• Administrators: Need to review Power Automate policies for desktop flows and data access.
• End users: Potential for inadvertent data exposure through misconfigured automations.

The Action

1. Review existing Power Automate DLP policies to ensure they cover desktop flows and sensitive data handling.
2. Implement or update Power Automate environment segregation strategies to limit data access for desktop flows.
3. Monitor Power Automate desktop flow activity for unusual access patterns to sensitive PowerPoint files.
4. Educate users on secure automation practices and the risks associated with handling sensitive data in flows.
