My capture-the-flag team played in the Insomni'hack teaser this year. During the competition, I worked on a single challenge titled "sapeloshop." It was labeled as "Medium-Hard," and it was in the binary exploitation category. The source code for the server wasn't provided, so reverse engineering was necessary. I don't think that having to reverse the binary was supposed to be the hard part, as most of the behavior could have been inferred through some high-level analysis, yet I spent nearly five hours fruitlessly trying to reverse it, and the subsequent burnout was bad enough that I went home early. This wasn't the first time a reversing task had gotten the best of me; there had been a few competitions last year where I felt a similar loss in motivation. Noticing this recurring pattern frustrated me, and that frustration drove me to think about ways to improve myself as a reverse engineer.
