by

In a series of blog posts throughout 2013, we emphasized on the lowering of the entry barriers into the world of cybercrime, largely made possible by the rise of managed services, the re-emergence of the DIY (do-it-yourself) trend, and the development of niche market segments, like the practice of setting up and offering bulletproof hosting for a novice cybercriminal’s botnet generating platform.
