6类顶级黑客大盘点

????漏洞经纪人

????身份：Endgame公司，Netragard公司，Vupen公司

????目的：把黑客行为当成合法生意

????目标：未可知

????特征：找到所谓的“零天攻击”代码（zero-day exploit）——即攻击新软件的方法，再把它们卖给政府和其他财大气粗的客户。

????经典案例：去年3月举行的一次安全会议上，法国公司Vupen黑掉了谷歌公司（Google）的Chrome浏览器。这家公司并没有（收下6万美元，）把这项技术和谷歌分享，而是把代码卖给了出价更高的客户。

????6. Vulnerability Broker

????Who: Endgame, Netragard, Vupen

????Objective: Hacking as legitimate business

????Targets: Agnostic

????Signature: Finding so-called zero-day exploits -- ways to hack new software, selling them to governments and other deep-pocketed clients

????Classic Case: French firm Vupen hacked Google's (GOOG, Fortune 500) Chrome browser at a security conference last March. Rather than share its technique with the company (and accept a $60,000 award), Vupen has been selling the exploit to higher-paying customers.
