DocBleach is a Content Disarm and Reconstruction (CDR) software designed to sanitize Office documents by removing potentially malicious dynamic content. The tool processes Office files to identify and eliminate misbehaving elements that could pose security risks, including macros, embedded objects, and other active content that might be used for malicious purposes. DocBleach operates by reconstructing documents in a safe manner, preserving the original content while stripping away potentially dangerous components that could be exploited by attackers. The software is particularly useful for organizations that regularly receive documents from external sources and need to ensure these files are safe before opening or distributing them internally. By implementing content disarmament techniques, DocBleach helps prevent document-based attacks and reduces the risk of malware infections through seemingly legitimate Office files.
