AI-suggested
1. Educate users to avoid opening InDesign files from untrusted or unknown sources, especially unsolicited email attachments or downloads. 2. Implement strict email filtering and attachment scanning to detect and block potentially malicious InDesign files. 3. Use endpoint protection solutions with behavior-based detection to identify suspicious activities related to InDesign processes. 4. Employ application whitelisting to restrict execution of unauthorized code and scripts. 5. Isolate systems used for opening external InDesign files in sandboxed or virtualized environments to limit potential damage. 6. Monitor system and network logs for unusual behavior indicative of exploitation attempts. 7. Maintain regular backups of critical data to enable recovery in case of compromise. 8. Stay informed about Adobe’s security advisories and apply patches immediately once available. 9. Consider disabling or restricting InDesign file handling capabilities temporarily in high-risk environments until a patch is released. 10. Coordinate with IT and security teams to develop incident response plans specific to this vulnerability.
