Today, Julian Assange is known as the creator and public face of Wikileaks, the online organization that publishes leaked government and corporate documents. But before all that, way back in the late 80’s at the young age of 16, he was known as Mendex and together with two other hackers formed International Subversives, what they consider to be an ethical hacking group.

He went on to hack into several high-profile targets such as the US Department of Defence, NASA, Lockheed Martin, just to name a few. He was eventually caught while hacking into Nortel in 1991 at the age of 20. He pleaded guilty to 35 charges. He managed to avoid heavy penalties due to perceived non-malicious intent and a disrupted childhood, caused by his mother being part of a controversial New Age group and frequently moving about.
