This is a post in a series where I complete every Flare-on challenge. The landing page for all of these posts can be found here
The first challenge in the 2015 season on Flare On was a pretty easy enter the password type of challenge. I started off by opening the extracted file in IDA and running it in the debugger. I stepped to the section of code that evaluates the input versus the input
I extracted the encoded key from memory
Then I re-implemented the XOR encryption in python and generated the key from the data.
Which successfully worked!
