What is Binary Exploitation
Binary exploitation is a technique used in cybersecurity to take advantage of weaknesses in software at a very basic level. Binary exploitation focuses on manipulating the machine's code, to perform actions it wasn't designed to do.
- Binary exploitation focuses on vulnerabilities in compiled programs, often called binaries. These are the machine code instructions that the computer directly executes.
- By manipulating the code, attackers (or ethical hackers) can make the program do things the developers never intended, such as granting unauthorized access or stealing data.
Techniques:
- Stack Buffer Overflow
- Format String Vulnerabilities - When the parameter count to
printf()is less than the number of format specifiers in the format string you can read from and write to the stack, including the return instruction pointer.
