: 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 program will crash. Check the offset of the value in the $rsp register to determine the padding (usually around 40–72 bytes depending on the local variables). pwn_bloodh7nt.rar

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. : There is a hidden function in the

In this specific challenge, many players ran into a common 64-bit exploitation issue: . The win() function likely calls system() , which requires the stack to be 16-byte aligned. If your exploit crashes at the movaps instruction inside system() , adding a dummy ret gadget (as shown in the script above) before the win_addr usually fixes the issue. Summary for a Blog Post Difficulty: Easy/Beginner. Key Concept: Stack Buffer Overflow & Stack Alignment. Tools Used: pwntools , gdb-pwndbg , checksec . Finding the Offset The program will crash

To control the program's flow, you first need to find exactly how many bytes are required to reach the return address. You can use with the pwndbg or GEF extension.

Once you have the offset and the address of the win() function (found via info functions in GDB or nm binary ), you can write a simple Python exploit using the library:
