Perfidy, Deception, Fraud - How Much Trust Should We Put in a PDF? (gpn23)
In our daily life, we often think of PDF documents as static and immutable. This mental model is wrong.
In this presentation, we give a brief overview of PDF (in-)security and describe a novel kind of attack where a malicious PDF document can
* change its displayed content with time (while the file stays the same)
* display different content to different people
We publish details and a proof of concept at https://github.com/vlkl-sap/perfidy-deception-fraud
