The Pangea Sanitize service allows users to remove objects and text that might be malicious and returns a clean document through a complete breakdown and rebuild processing of the file known as Content Disarm and Reconstruct (CDR). The amount of sanitization completed on the file is customizable via the Settings menu in the Pangea User Console.

Content Disarm and Reconstruct

CDR is a process where a file, such as a document, is sent to a service to be analyzed for any content that might be malicious. This analysis looks for macros, suspicious code, embedded objects, and other items that could hide or contain anything that can be harmful to the user.

After the file has been analyzed and possibly malicious content has been removed, it is then reconstructed as close to the original file as possible. It should retain all of the content and most of the functionality (some functionality might be removed due to possible malicious content) of the original file and be able to be used by the application that created the original file.

Benefits of CDR

CDR retains the data of the original file while removing content (based on settings) that could be malicious, which protects against many attacks, even zero-day attacks. This limits the amount of risk that users and assets are exposed to, providing an extra barrier of protection against threats. It is a valuable addition to a security protocol for various application types that provide file storage and sharing.

Another benefit of CDR is that the file is rebuilt from scratch using the text of the original file. Malformations in the file or its embedded contents are often removed during the reconstruction process, helping prevent exploits of these malformations.
