Create a cyclic pattern (e.g., cyclic 100 ) and input it when prompted for your name.
The binary is a simple 64-bit ELF executable. When run, it simulates a "Blood Hunt" game where you input a name and choose an action. The core of the vulnerability lies in the input handling for the player's name. pwn_bloodh7nt.rar

: There is a hidden function in the code, typically named win() or secret_weapon() , that prints the flag. Your goal is to redirect execution to this address. 2. Finding the Offset The core of the vulnerability lies in the
