So in my spare time I will sometimes create vuln VM challenges, reverse engineering challenges etc. For me I get to see all the cool ways that different people solve problems etc. In my mind, I have my method of how I go about doing things so it's cool to see how others approach the same things and what their thought process is. Big shout out to vulnhub.com for hosting my latest VM challenges. Here are a couple RE challenges that I have come up with. I have also submitted them to crackmes.de but they are waiting for approval. Feel free to take a crack at these and submit a write up or video on how you solved them!
