Just finished “An Army of Bots” whitepaper by SecureState. It is a 13 page document (with larg-ish font) which covers off on botnets at a high level. Personally, while I found some areas interesting, just the emotive language and vagueness left me wandering if this is not a mislabelled marketing paper. Do not get me wrong, it never mentions any services, but it just comes across as the type of thing people send to managers before hitting them up with a proposal a few days later.
So, if you know nothing about botnets give it a read. If you know something, try it anyway and let me know if I am wrong.
