Next on Insight - a rare chance to hear hackers and 'hacktivists’ talk about what they do and why. They're hacking into computers and defacing or crashing websites. 'LulzSec’ made headlines earlier this year when it claimed to have hacked into Sony accounts, compromising the personal data of thousands of customers. 'Anonymous’ says it was behind attacks on Australian Government websites during debates over internet censorship. But little is known about the hackers themselves and what propels them to act. This week, Jenny Brockie speaks directly with hackers and hacktivists – some of them wearing masks, disguises and using voice distortion devices – to ask them how they choose their targets, and where they draw the line.
