\section*{Handout 3 (Buffer Overflow Attacks)}+
−
+
−
By far the most popular attack method on computers are buffer+
−
overflow attacks. The popularity is unfortunate since we now+
−
have technology to prevent them. But these kind of attacks are+
−
still very relevant even today since there are many legacy+
−
systems out there and also many modern embedded systems+
−
do not take any precautions to prevent such attacks.+
−
+
−
To understand how buffer overflow attacks work we have to have+
−
a look at how computers work ``under the hood'' (on the+
−
machine level) and also understand some aspects of the C/C+++
−
programming language. This might not be everyday fare for+
−
computer science students, but who said that criminal hackers+
−
restrict themselves to everyday fare? Not to mention the+
−
free-riding script-kiddies who use this technology without+
−
knowing what are the underlying ideas.+
