[MacTUG] FYI: Apple's Preview app passes on unnoticed data fragments - The H Security: News and Features

[Marlon A. Griffith]

"""
While Preview explicitly notes, when cropping selected areas, that "cropping a PDF document doesn't delete the content outside the selection", but merely hides it, this warning is not displayed when copying the selected area. As a result, users may find themselves inadvertently passing on sensitive content. Until Apple fixes this, users who create or edit PDF files using the Preview app should remember that the entire page is retained and can be viewed with certain applications.
