None of the 315 international contendants managed to send in a full crack of the encryption scheme. Between May 15th and June 2nd, they were requested to hack the protected game and prove they could run it without the provided dongle and without any Internet connection to a jury consisting of IT security scientists and independent from the challenge partners (Wibu-Systems, Karlsruhe Institute of Technology, and FZI ResearchCenter for Information Technology). The contenders were delivered a game application protected with Blurry Box cryptography that came with its license stored in a CmDongle. The underlying principle of Blurry Box is the exact opposite of “security through obscurity” based on Kerckhoffs’ Principle, Blurry Box cryptography uses published methods that greatly increase the complexity and time required for an attack to be successful. To test the validity and strength of the newly patented encryption method Blurry Box, integrated with the anti-debug and obfuscation methods of CodeMeter Protection Suite, we launched a new contest, open to all hackers around the globe.
