如何破解滑动验证码？

本文通过自动化查询域名或公司的备案信息，来演示其中图片滑动验证码的破解方式，以此来思考验证码的安全性问题，思考如何设计出安全性更高的验证码。

注意：破解验证码进行网络内容抓取可能是一种违规行为，可以以此进行验证码安全性分析研究，不要用于恶意活动。

什么是验证码

现在的 web 应用，在进行重要操作时，比如用户登录、信息修改、重要信息查询等，往往都需要验证码。验证码的主要目的是防止自动化程序或机器人在网站上执行恶意操作。

图片形式的验证码是最常用的一种形式，下面列出几种常见的图片形式验证码：

这里要注意的是，虽然同一个种类的验证码的前端表现可能相同，但是背后实现的方式可能不同。

自动破解验证码

破解验证码是通过各种技术手段来自动识别或者绕过验证码验证，尽管验证码的设计者在不断改进验证码的安全性，但是验证码破解方式也在不断创新，这使得验证码的安全性不断受到挑战。

通过上面的介绍，我们知道验证码的种类很多，因此不同种类验证码的破解方式也不相同，而且由于实现方式的不同，往往需要具体情况具体分析。

图片验证码破解的总体思路是模拟用户的操作进行验证码验证。

举例：

• 针对图片内容识别类验证码，可以识别图片中的内容进行自动验证，这里可能要利用机器学习或图像处理技术来识别内容。
• 针对图片滑动、旋转类验证码，可以模拟用户操作，如计算图片要滑动的距离，要旋转的角度，模拟人类鼠标操作时的轨迹曲线等。
• 或者直接人力破解，针对有价值的目标，也有聘请人工智能平台或工人手动识别并解决验证码的情况。

本文介绍图片滑动验证码的破解方式，这是一种破解起来相对简单的验证码。

图片滑动验证码

图片滑动验证码是一种比较常见的验证码，一般都是通过滑动图片的一部分进行图片拼图，以进行操作验证。示意图像下面这样。

从用户体验来看，用户只需要使用鼠标拖动滑块到指定位置，如果位置正确，则通过验证。这是一种十分好用的验证方式，相比输入形式的验证码，省去了用户键盘的输入过程。

这类验证码的实现过程一般如下：

具体案例分析

我们通过分析一个备案查询网站来演示滑动验证码的破解，目前网站的操作流程是输入一个域名或者公司信息，点击查询，弹出图片滑动验证码，用户滑动图片验证码进行验证，验证通过则返回查询信息。

我们先通过查看网站的网络请求情况，分析操作背后的流程（以下的操作并不是一次完成，所以截图中的某些值可能对不上）。

访问网站

访问网站 beian.miit.gov.cn，发现自动请求了 auth 接口，在请求时携带了两个参数，截图如下。

其中 timeStamp 很明显是一个毫秒时间戳，那么 authKey 值是怎么来的呢？通过分析网站 javascript 代码，可以发现它的生成规则为 MD5('test'+test'+timeStamp)，分析截图如下。

请求后获取到了一个 bussiness 信息，作为后续请求的认证 token。

获取验证码

在网站上搜索一个域名，弹出图片验证码信息，再次查看请求信息。发现发起了一个 POST 请求，并且在请求头中携带了 Token 信息用于认证，这个 Token 就是第一步获取到的 bussiness。

响应信息是 base64 编码后的图片，一个是大图，一个是用于滑动的方块，其中的 uuid 可以认为是图片 id，在图片验证时需要传给服务器。

// 下面的响应信息，为了方便查看，我删去了部分内容，所以不要直接解码，解不出来的。
{
    "code": 200,
    "msg": "操作成功",
    "params": {
        "smallImage": "/9j/4AAQSkZJRgABAQEAYABgAAD/2wBDAA0JCgsKCxxxxxxxxxxxxxx",
        "bigImage": "/9j/4AAQSkZJRgABAQEAYABgAAD/2wBDAA0JCgsKCA0lFAj/2Qxxxxxxxxxxx",
        "uuid": "87db2dbb-4c1d-4633-a624-0045305e61e3",
        "height": "81"
    },
    "success": true
}

如果我们拿 bigImage 内容进行 Base64 转图片，可以看到验证码大图。

验证码校验

我们滑动图片验证码到准确位置，这时会发起验证请求，我拷贝出了这条请求的详细信息。

curl 'https://hlwicpfwc.miit.gov.cn/icpproject_query/api/image/checkImage' 
  -H 'Accept: application/json, text/plain, */*' 
  -H 'Accept-Language: zh-CN,zh;q=0.9'

  --data-raw '{"key":"6af2c1bb-47a4-479d-a9f1-1ab17f86214e","value":"320"}' 
  --compressed

从中可以发现，依旧在请求头中携带了 Token 字段。同时请求体携带了 key 和 value 两个字段，其中 key 就是上一步获取到的图片的 uuid，value 则是滑动验证码滑动的距离。320 也就是表示滑动了 320 个像素位置进行了拼图。

验证通过后得到响应信息，其中 params 是验证后得到的可以用于请求验证的值。

    "code": 200,
    "msg": "操作成功",
    "params": "eyJ0eXBlIjozLCJleHREYXRhIjp7InZhZnljb2RlX2ltYWdlX2tleSI6IjZhZjJjMWJiLTQ3YTQtNDc5ZC1hOWYxLTFhYjE3Zjg2MjE0ZSJ9LCJlIjoxNjg5MDg4NDQ0MTM2fQ.cYPpQya1KiWZgC3T8ZNr9cWAM2aTHDtFUpzPIO-sMhQ",
    "success": true
}

信息返回

验证通过后会自动请求域名备案信息查询接口，下面是复制出的请求信息。

其中 sign 是图片校验通过后的验证信息。token 是第一步获取到的验证信息，uuid 是验证码唯一标识。请求参数中的 unitName 值是要查询的域名 qq.com。

请求后成功响应了域名备案信息，至此，我们完整的分析了备案信息查询的全过程。

图片滑动验证码破解

如何破解验证码呢，通过上面的具体案例分析，我们发现其实在访问网站获取 Token阶段，获取验证码阶段，以及最后的信息返回阶段，都是比较简单的 HTTP 请求，只要能构造相应的 HTTP 请求，并携带具体的请求头信息，就可以模拟请求了。

比较不好办的是验证码校验这个阶段，因为要计算验证码的滑动距离，这里需要涉及到图像处理知识，那么该怎么办呢？

验证码图片分析

我们获取几张验证图片观察，明显看到在要滑动的目标区域有被阴影覆盖，那么这一部分的 RGB 颜色就有所变化，一个正常的图片很少有这种矩形方块的颜色突变。

灰度图片

通过上面的分析，我们发现色彩其实并不重要，图片的灰度变化（或者叫亮度变化）比较重要，因为目标区域有被灰色覆盖。会产生一个矩形突变，那么我们可以把图片转换成灰度图片，这样更有利于观察。

准备验证图片一张，对应的 base64 编码如下：

                int gray = Double.valueOf((color.getRed() * 0.2126 + color.getGreen() * 0.7152 + color.getBlue() * 0.0722)).intValue();
                // 将像素点的颜色设置为非黑即白

}

这样可以把图片转换成下面的这个样子。

其实这时，如果我们输出图片的每个像素点的灰度矩阵，已经可以发现灰色方块处的灰度特点了。可以很明显的看到灰色方块区域的灰度值变化。

如果你检测这个灰度矩阵，你已经有办法找到灰色区域开始的位置了。

图片二值化

为了更方便的分析，我们可以对图片再次转化，我们可以选取一个阈值，**超过指定阈值的像素点直接转换成白色，低于指定阈值的颜色转换成黑色。**这样更方便后续的分析。

改造代码，添加亮度阈值判断，这里选择 100 作为阈值。

for (int y = 0; y < height; y++) {
    for (int x = 0; x  100) {
            gray = 255;
        } else {
            gray = 0;
        }
        
        Color newColor = new Color(gray, gray, gray);
        image.setRGB(x, y, newColor.getRGB());
    }
}

转换后的图片变化如下：

如果我们打印这个二值化后的图片像素矩阵，可以更加清楚的看到灰色矩形区域几乎都是 0 值。

滑动距离计算

对二值化后的图片进行计算，可以非常方便的找到灰色矩形开始的位置，只需判断每个 (x,y) 像素值和前一个像素 (x-1,y)的值变化情况即可。如果某一列出现大量从 255 变化到 0 的像素，这里很大概率是达到了矩形的第一个边界，这列所在的 x 值就是要移动的距离。

简单的计算方式如下：

// lightArray 存储了二值化后的图片像素信息
// 扫描发现 255->0 变化的最大数量
int maxChangeCount = 0;
// maxChangeCount 对应的列值
int index = 0;
for (int w = 1; w < width; w++) {
    int changeCount = 0;
    for (int h = 0; h  maxChangeCount) {
        maxChangeCount = changeCount;
        index = w;
    }
}
log.info("分析得到验证码坐标值：{}" , index);

针对用于测试的熊猫验证码图片，计算得到滑动距离为 127，验证图片发现距离也大概是 127px 左右。

至此，图片滑动验证码自动化破解完成。

由于测试的网站并没有加入拖动轨迹的验证，某些滑动验证码会分析鼠标拖动的轨迹来判断是否是人工拖动。

如果我们模拟 HTTP 请求，串起所有的步骤，那么就可以自动化查询域名的备案信息。下面是我的测试（合规原因，完整代码就不贴了，如果需要完整代码可以找我（公众号或微信））。

总结

本文介绍了常见的图片验证码形式，紧接着具体介绍了图片滑动验证码的实现原理，并选择一个网站进行具体的图片滑动验证码验证流程分析，最后介绍如何破解图片滑动验证码，主要是如何计算图片滑动的距离。
