We've decided to publish our findings and tools, in hope that someone will find it useful, interesting or will continue our research. We will describe the vulnerability, and how we improved our decryptor computational complexity and performance to reach an almost practical implementation.

The Artemis vulnerability scanner is now open source! Artemis is a tool developed by the CERT Polska team and initiated by the KN Cyber science club of Warsaw University of Technology.
