For this exercise, you are going to start with this site: https://botlab.org.
BotLab is a platform at the University of Washington that continually monitors and analyzes the behavior of spam-oriented botnets.
There are many other locations on the Internet that keep real-time activities of botnets across the globe.
My recommendation is to use your favorite search engine and search "real-time botnet tracking" and you will hit many results on botnet tracking.
Using the information you found, develop a five-slide PowerPoint (seven bullets minimum per page) to describe the status of botnets in the world.
