Billy Hoffman and Matt Wood of the HP Web Security Research Group are generating serious heat with their upcoming BlackHat USA presentation which will detail their browser-based darknet. Articles on Dark Reading, Forbes.com, and Slashdot are just the beginning. Why the buzz? Well, darknets are virtual private networks where users only connect to other 'trusted' users. Darknets normally require installation of some sort of client-side software, firewall configuration, and all other sorts of rigmarole. What Billy and Matt have done is to create a darknet that gives users a way to communicate and share files anonymously just using a browser. It's impressive stuff. Check out the articles here, and stay tuned for more details:
