会话劫持防范
• 防范会话劫持是一个比较大的工程。 1. 首先应该使用交换式网络替代共享式网络,虽然像Hunt这
• 在通讯过程中,双方的序列号是相互依赖的,如 果攻击者直接进行会话劫持,结果肯定是失败的。 因为会话双方“不认识”攻击者,攻击者不能提供 合法的序列号;所以,会话劫持的关键是预测正确 的序列号,攻击者可以采取嗅探技术获得这些信 息。
jack原理
• 会话劫持(Session Hijack): 就是结合了嗅探以及 欺骗技术在内的攻击手段。例如,在一次正常的 会话过程当中,攻击者作为第三方参与到其中, 他可以在正常数据包中插入恶意数据,也可以在 双方的会话当中进行监听,甚至可以是代替某一 方主机接管会话。

Https会话劫持之SSLStrip (3)
• SSLstrip工作原理:
– SSLstrip通过监视Http传输进行工作,当用户试图 进入加密的https会话时它充当代理。当用户认 为安全的会话已经开始时,SSLstrip也通过https 连接到安全服务器,所有用户到SSLstrip的连接 是http,这就意味着浏览器上警告提示已经被阻 止,浏览器看起来正常工作,在此期间所有的 用户敏感信息都可以轻易被截获。

TCP Session Hijack方法
