What you'll learn

Many aspiring penetration testers find themselves overwhelmed by the multi-step process of exploiting buffer overflow vulnerabilities under exam conditions, struggling to move from a simple crash to a full, reliable shellcode attack. In this course, Buffer Overflow for Offensive Security Professionals, you’ll learn to systematically exploit Windows buffer overflow vulnerabilities from fuzzing to shellcode delivery. First, you’ll explore fundamental concepts like stack layout, DEP, ASLR, EIP, bad characters, and the basics of Immunity Debugger. Next, you’ll discover the critical workflow of fuzzing a vulnerable application, replicating crashes, finding EIP offsets, controlling execution flow, expanding padding space, and pinpointing bad characters. Finally, you’ll learn how to locate a JMP ESP gadget, craft and encode shellcode with msfvenom, and deploy a complete exploit from your Kali Linux machine. When you’re finished with this course, you’ll have the skills and knowledge of Windows buffer overflow exploitation needed for the OSCP exam.
