”In the physical world criminals require hiding places (underground). Cyber criminals, on the other hand, do need hiding places for their online offering. In short, they need: bulletproof hosting services. Actually, Bulletproof Hosting Service providers know that criminal activities are taking place on their servers: Drugs are being sold. Stolen credit card data is being deposited. Even child pornography is being stored and dealt with.
