PDF Insecurity at NDSS 2021
04.03.2021 – Vladislav Mladenov
Recently, we have published two papers on the „NDSS Symposium 2021„.
Our first paper is „Processing Dangerous Paths – On Security and Privacy of the Portable Document Format“ and deals with the security issues in PDF files. In the paper, we answer the question „What could go wrong if you open a PDF file?“.
Our second paper „Shadow Attacks: Hiding and Replacing Content in Signed PDFs“ presents novel attacks on PDF signatures. The attacks allow the manipulation of digitally signed PDF documents without causing any warning by opening the file.
More information can be found on „pdf-insecurity.org„, in our blogposts („Blogpost: PDF Dangerous Paths„, „Blogpost: PDF Shadow Attacks„), and videos („Youtube: PDF Dangerous Paths„, „Youtube: PDF Shadow Attacks„).
