VB2017 paper: Crypton - exposing malware's deepest secrets

Posted by   Martijn Grooten on   Oct 27, 2017

Computer scientists are notorious for a specific kind of laziness: the kind of laziness that makes them work really hard in order to avoid some other, often more boring, hard work.

Crypton, a tool developed by F5 Networks researchers Julia Karpin and Anna Dorfman, is a great example of that: it aims to speed up the reverse engineering process by decrypting encrypted content found in a (malicious) binary.

Such a tool can be a great help in itself, but even better is the fact that Julia and Anna wrote a detailed description of the development of the tool in their VB2017 paper – which they then presented at the conference in Madrid.

Today, we publish the paper in both HTML and PDF format; we have also uploaded the video of Julia and Anna's presentation to our YouTube channel.
