What you'll do
In this lab, we will continue our look at how stack canaries are used to prevent stack based buffer overflows and potential ways that they can be defeated.
- We will be using gdb with the gef plugin to examine the binary and help develop the exploit.
- We will then use python with pwntools to develop an exploit script.
- In this part, we will examine how arbitrary memory reads and writes can be used to defeat canaries.
