What are buffer overflow attacks?

A buffer overflow attack is when too much information tries to fit into a small space and messes things up.

Imagine you have a toy box that can only hold 10 toys. One day, you try to put 20 toys in it, the extra ones spill out and knock over your favorite blocks nearby. That’s like a buffer overflow, too much data goes into a place that wasn’t meant for so much, and it causes problems.

A buffer is like a toy box, it holds information temporarily while something else happens. A computer uses buffers to store things like names, numbers, or messages. But if the buffer gets too full, the extra information can overflow into other parts of the computer’s memory, causing strange behavior or even letting someone take control.

Buffer overflow attacks are used in real life, sometimes by hackers trying to break into computers. They send more data than a program expects, and that little overflow can trick the computer into doing things it wasn’t supposed to do, like letting the hacker log in as you!
