We have published two papers on the 26th ACM Conference on Computer and Communications Security in London.
Our first paper is 1 Trillion Dollar Refund -- How To Spoof PDF Signatures and deals with the insecurity of PDF Signatures.
Our second paper is Practical Decryption exFiltration: Breaking PDF Encryption and shows how to extract plaintext out of encrypted PDFs.
More information can be found on PDF-insecurity.org and in our Blogposts "How to Spoof PDF Signature" and "PDFex - Major Security Flaws in PDF Encryption".
