Attachments

Acrobat products allow you to open and save attachments to PDF files. However, attachments represent a potential security risk because they can contain malicious content, open other dangerous files, or launch applications. Certainly file types such as .bin, .exe, .bat, and so on will be recognized as threats by most users and are not allowed as attachments. Adobe applications maintain attachment black and white lists that can be modified and locked by the administrator.

For related preferences associated with blacklisting and whitelisting filetypes, see the Attachments key details.
