I periodically get email from ios users with invisible attachments.
TLDR: view raw, save base-64 to text, uudecode using
certutil --decode(a native tool in Win7+)
Last night I finally figured out what is going on: the attachment is marked as "inline" in the header, but the client (gmail in this case, but can happen with others too) doesn't render the attachment correctly. However since the media is inline it's not visible/extractable like regular attachments are.
- Email says there is in attachment (e.g. has a paperclip), but there is no place to click and save or download the attachment
- broken image icon in message body
- view original/raw message
Content-Disposition: attachment; filename="some_filename.pdf"and save everything between
--Apple-Mail-AAA888...--lines (don't include those lines) to a text file, e.g.
- open command shell and run
certutil -decode some_filename.uue some_filename.pdf
