Buffer Overflows
Master the fundamentals of buffer overflow exploitation by building a complete exploit chain against a vulnerable application. You'll start by triggering crashes with malformed input, identify the precise buffer length, and confirm control of the instruction pointer (EIP). From there, you’ll test for bad characters, gauge available shellcode space, and craft a reliable exploit buffer. The final payload will redirect execution into custom shellcode to gain a remote shell, all using WinDbg and hands-on analysis techniques essential for OSCP-level exploitation.

Table of Contents
-
Challenge
Fuzz and Crash the Application
Discover whether the application crashes from malformed input and identify the buffer length that causes it.
-
Challenge
Find and Control the Instruction Pointer
Determine if you can overwrite the instruction pointer (EIP) and control program execution after the crash.
-
Challenge
Identify Available Space and Discover Bad Characters
Determine how much space is available for shellcode, test for bad characters, and prepare a safe exploit buffer.
-
Challenge
Exploit the Buffer Overflow and Get Shell
Craft a final payload that uses your control of the instruction pointer (EIP) to redirect execution to your shellcode.
Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
