Buffer Overflow Hunter

Three vulnerable C functions. Each one has a buffer that the input writes into without a bounds check. Your job: build the payload bytes that overwrite the saved return address with the win() function. The stack is shown to scale.

Educational training material. This game demonstrates an attack technique inside a sandboxed quiz UI for security learning. Do not apply these techniques against systems you do not own or have explicit written permission to test.
