Buffer Overflow Attack Demo

Memory Exploitation Lab

Master the fundamentals of buffer overflow exploitation. Learn how attackers corrupt memory, overwrite return addresses, and inject shellcode to gain control of vulnerable applications. Understand stack-based exploits and modern protection bypasses.

Buffer Overflow Attack Demo

Interactive terminal demonstration with step-by-step walkthrough

📚 What You'll Learn

Understand stack memory layout
Identify buffer overflow vulnerabilities
Calculate offset to return address
Craft and inject custom shellcode
Use pattern generation for offset discovery
Bypass basic stack protections

🛡️ Defense Takeaways

Enable ASLR (Address Space Layout Randomization)
Compile with stack canaries (-fstack-protector)
Use non-executable stack (NX bit)
Implement bounds checking in code
Use safe string functions (strncpy, snprintf)
Deploy modern compilers with CFI

⚡ Exploitation Steps

Step 1: Analyze vulnerable binary
Step 2: Find buffer size and offset
Step 3: Locate return address
Step 4: Generate shellcode payload
Step 5: Craft exploit string
Step 6: Execute and gain shell
