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 .

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: 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. In this specific challenge, many players ran into
