Description

What is Buffer Overflow
Buffers are memory storage regions that temporarily hold data while it is being transferred from one location to another. A buffer overflow (or buffer overrun) occurs when the volume of data exceeds the storage capacity of the memory buffer. As a result, the program attempting to write the data to the buffer overwrites adjacent memory locations.

For example, a buffer for log-in credentials may be designed to expect username and password inputs of 8 bytes, so if a transaction involves an input of 10 bytes (that is, 2 bytes more than expected), the program may write the excess data past the buffer boundary.

Buffer overflows can affect all types of software. They typically result from malformed inputs or failure to allocate enough space for the buffer. If the transaction overwrites executable code, it can cause the program to behave unpredictably and generate incorrect results, memory access errors, or crashes.

The primary goal of this course is to provide you with practical exposure to the world of bug hunting. After taking this course, you will have a better understanding of the approaches (reverse engineering, exploit development) that bug hunters use to find security vulnerabilities. You will learn how to exploit Buffer Overflows on Windows systems. This is an initial course and begins from the very basics of exploitation and is beginner-friendly.
