Can MD Core process the attached files in a PDF file?

Adobe Acrobat allows users to attach additional files to a PDF, which can be exploited to deliver hidden threats to a system. These attachments often remain undetected, as they are only visible when the PDF is opened with Adobe’s PDF readers.

MetaDefender Core is capable of processing these embedded files. It extracts the attachments and sanitizes their contents to eliminate potential threats.
