One evening, you decide to take a look at the website of Awesome Corp., a competitor which you suspect of reverse-engineering parts of your software and using these code pieces in their own product. Unfortunately, you got no proof, so you begin to investigate on your own.

Soon enough (insert random webhacking stuff here), you get access to an administrators inbox. It seems like they use a custom authentication system which manages access to internal resources like SVN servers and such. It is called ‘Secured Range’ and is in use since January 2011, as the logs state. All you manage to retrieve before an administrator throws you out of the system are two binaries of their login system:


The first seems to update masterkeys every few months, the latter produces authentication tokens for the employees. Try to get hold of the system’s current master key to solve this challenge.
