CNN CloudFlare CEO Matthew Prince discusses cybersecurity and threats from hackers at the RSA conference. SAN FRANCISCO (CNNMoney) -- On June 2, hacktivist collective "LulzSec" burst onto the cybersecurity scene with a splashy exploit: It published a trove of data stolen from 1 million user accounts on Sony's website. LulzSec's website immediately crashed under a massive traffic attack from foes seeking to hack the hackers. Within the hour, LulzSec signed up for a website optimization service called CloudFlare -- and nine minutes later, its site was back online. That's how CloudFlare , a Silicon Valley startup with a staff of 30, found itself in the middle one of the year's biggest cybersecurity battles. "Everyone -- from three-letter government agencies to white-hat hackers to black-hat hackers -- spent the next 23 days trying to discover, 'Where exactly is Lulz hosted, and how can we knock them offline?," said CloudFlare CEO
