Cookie欺骗 腾讯拍拍秒杀活动的验证码漏洞
请猛击下载：http://blog.csdn.net/wyw308/archive/2011/05/10/6408159.aspx
结合网络上前辈的宝贵经验，配合自己手动抓包分析。发现：
1：再进入倒计时时无论你点刷新有多快，其实页面都是5秒钟才给你提交一次。（可恶的拍拍，蒙了多少朴实鞋童，没分析之前按一到抢拍时间就狂点“刷新”按钮，现在才明白白瞎了）
2：腾讯的验证码来源于第三方服务器，其Set-Cookie并不是保存到本地的cookie，它是一个标志为httponly的cookie，只存储在标头。具体的验证码地址为专门服务器http://captcha.qq.com/getimage，因此可以进行cookie欺骗。
开发思路：
1：考虑人性化效果，利用webBrowser模拟页面登陆进入抢拍界面，利用webBrowser动态生成主要cookie及post数据元素。
2：手动提前获取多组验证码，保存到容器。
3：时间一到，利用提前获取的验证码，手工构造post数据以及cookie数据，利用httpwebrequest进行底层自动提交。
4：查看返回结果。

一：取宝贝的开始剩余时间:注意，拍拍网对于宝贝的开始抢拍时间有延时处理，比如倒计时到了3,2,1，娘的，他不开始，又重新回到了3,3,3。。。然后忽然就开始了，这里需要进行一些技术处理，如自己延时或者直接网上核对，但各有利弊，具体方法大家自己想。这里只给取倒计时by/ http://blog.csdn.net/wyw308
/// <summary>
/// 返回倒计时毫秒by/ http://blog.csdn.net/wyw308
/// </summary>
/// <returns></returns>
private double RemainTime(out string jsonstr)
{
Random ran = new Random();
double c = ran.NextDouble();//随机处理by /http://blog.csdn.net/wyw308
string url = "http://ext.paipai.com/oneaday/comdynum?" + GetInputValue("ComdyId") + "&t=" + c.ToString();//宝贝抢拍上架地址by/ http://blog.csdn.net/wyw308
CookieContainer cc = new CookieContainer();
HttpHelper.NetworkDelay =0 ;
HttpHelper.Encoding = Encoding.GetEncoding("GB2312");
string result = HttpHelper.GetHtml(url, cc);
result = HttpFunction.Regex_str(result, "{.+?}");
jsonstr = result;
Dictionary<string, object> aa = bym.Json.jsonFormat.Deserialize(result); //json格式化返回数据by /http://blog.csdn.net/wyw308
string a = aa["UploadSec"].ToString();
if (a != null && a != "")
return double.Parse(a) * 1000;
else
return -1;
}
二：验证码容器，将提前获取的验证码及cookie值保存到此，然后使用
/// <summary>
/// 验证码cookie极点队容器 by/ http://blog.csdn.net/wyw308

{
}

{

this.vcookie = VCOOKIE;
}

{

{
return this.vcode;
}
set
{

CookieContainer ckcode = new CookieContainer();
pictureBox1.Image = new Bitmap(HttpHelper.GetStream(url, HttpHelper.CookieContainer, out c_v));

三：根据页面动态手工构建post方法，这样比较灵活机动，操作起来交互效果好，by/ http://blog.csdn.net/wyw308

四：动态构建提交需要的cookie by/ http://blog.csdn.net/wyw308
