Binary Exploitation Techniques

Can someone break down the basics of binary exploitation, like buffer overflows and code injection?

Binary exploitation involves manipulating a program’s behavior by taking advantage of vulnerabilities in its code. Buffer overflows are a classic technique where you overflow a buffer with more data than it can hold, potentially overwriting adjacent memory. This can lead to code execution. Tools like GDB and PEDA can help you analyze and debug binaries.

To add to that, code injection is another technique where you inject malicious code into a program to make it execute your instructions. Depending on the vulnerability, this could lead to remote code execution or privilege escalation. Learning assembly language (ASM) is invaluable for understanding binary exploitation.

Before diving into advanced techniques, make sure you have a solid understanding of memory layout and stack frames. These concepts are fundamental for many binary exploitation scenarios. Books like “Hacking: The Art of Exploitation” by Jon Erickson provide excellent insights.
