一、Wappalyzer介绍
Wappalyzer 是一款浏览器插件，通过 Wappalyzer 可以识别出网站采用了那种 web 技术。它能够检测出 CMS 和电子商务系统、留言板、javascript 框架，主机面板，分析统计工具和其它的一些 web 系统。The company behind Wappalyzer 还能够收集 web 程序的一些信息用于统计分析，揭示出各种 web 系统的使用率即增长情况。实际 Wappalyzer 就是一个指纹识别工具。
例如：
二、设计原理
系统通过构造HTTP请求与目标Web服务器交互，从其响应数据包信息中提取提取指纹特征信息，然后通过与指纹数据库（Wappalyzer）进行比对，从而获取到Web服务器及应用的组件信息和版本信息。通过发现这些特征信息并对它进行识别可以帮助我们快速地制定渗透策略，是渗透环节中关键的一步。
