Decompetition is an experimental CTF just for reverse engineers. Test your reversing skills against the systems languages of the twenty-first century: C, C++, Go, Rust, and Swift. Given only a binary and an interactive disassembly diff, how accurately can you recreate the original source code? Come see how your decompilation skills match up!

Prizes

All prizes are Amazon gift cards (values in USD):

First place: $500
Second place: $300
Third place: $200
