A brief walkthrough of the buffer overflow attack known as Attack Lab or Buffer Bomb in Computer Systems course. There are 5 phases of the lab and your mission is to come up with a exploit strings that will enable you take control of the executable file and do as you wish. The first 3 phases include injecting small code while the last 2 utilize ...The address of the function starts at 4018ee but 58 is present on the 5th byte, so we need to add 4 bytes to the address.\nWe just want the bytes starting at that address. \n. 4018ee + 4 = 4018f2 \n.
