Ben Hammersley delves into the dark world of hacking, now home to a new generation of highly organised cybercriminals running complex commercial enterprises, involving leaders, planners, engineers, infantry and hired money mules. In the first episode, the Silk Road was a billion dollar drugs marketplace on the darknet, run by a mastermind called Dread Pirate Roberts. A year ago, the site was closed down by the FBI and its alleged founder was arrested in San Francisco. As his trial approaches Ben Hammersley delves into the world of alter egos, darknets and cryptocurrencies.
