It has been just over two years since Americans were really introduced to WikiLeaks. The high-profile releases of US State Embassy cables, war logs from Iraq and Afghanistan, and the “Collateral Murder” video turned the organization and its founder Julian Assange into a beat, which journalists or reporters were closely following. One journalist, who has closely tracked the organization and its founder, is Andy Greenberg of Forbes.

His book, This Machine Kills Secrets: How WikiLeakers, Cypherpunks and Hacktivists Aim to Free the World’s Information, covers what he describes as “a revolutionary protest movement bent not on stealing information but on building a tool that inexorably coaxes it out, a technology that slips inside of institutions and levels their defense against the free flow of data like a Trojan horse of cryptographic software and silicon.”
