AI-suggested

1. Monitor Adobe's official channels for patches addressing CVE-2023-44365 and apply updates promptly once available. 2. Until patches are released, implement strict email filtering and attachment scanning to block or quarantine suspicious PDF files. 3. Educate users about the risks of opening unsolicited or unexpected PDF attachments, emphasizing caution with emails from unknown or untrusted sources. 4. Employ application whitelisting and sandboxing techniques to limit the execution context of Acrobat Reader and contain potential exploitation. 5. Restrict user privileges to the minimum necessary to reduce the impact of arbitrary code execution. 6. Use endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts. 7. Consider disabling JavaScript execution within Acrobat Reader if not required, as this can reduce attack surface. 8. Maintain regular backups and incident response plans to quickly recover from potential compromises.
