Vorpal Masters (Web) - PatriotCTF
This writeup reverses a small license binary from PatriotCTF 2025 to recover the valid key CACI-2025-PatriotCTF. By inspecting the format string, strcmp checks, byte-by-byte comparisons, and a simple arithmetic check on the numeric field, the three segments are revealed and assembled into the final license.
