爆破带有验证码认证的请求

  • 本地ocr ddddocr
  • 多线程
  • 支持payload自定义二次处理(插件)2022.06.10更新
  • 支持用id检查验证码的类型 2022.06.13更新

使用方法

初始

  1. 拉取和配置环境
git clone https://github.com/AbelChe/BlastWithCaptcha.git
cd BlastWithCaptcha

pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple
  1. 请求文件

以账号密码登录认证为例

  • blast.txt

从burpsuite等工具中复制登录的请求包到blast.txt

在get或post参数中标记需要爆破的参数位置,如下所示,爆破username password 以及验证码 validCode

使用$<index>$标记,注意这里需要按照index的顺序设置config.yaml字典列表的顺序

设置字典列表时,验证码位置忽略顺延即可

这里1 2 3位置的对应关系:1、2对应config.yml的target.WORDDICT_LIST,3对应target.CAPTCHA_INDEX

POST /api/login HTTP/1.1
Host: example.com.test

Connection: close

{"username":"$<1>$","password":"$<2>$","validCode":"$<3>$"}
  • captcha.txt

直接复制burpsuite中请求验证码的数据包即可

GET /captcha.jpg HTTP/1.1

另外,无需考虑blast.txtcaptcha.txt的cookie对应关系,程序会自动生成新回话

  1. 配置

配置文件config.yml

system:
  PROXY: # 上行代理 例如 127.0.0.1:8080
  REQUEST_RETRIES: 5 # requests 的重试
  ONCETIME_THREAD_POOL_SIZE: 1 # 并发数

  TRYAGAIN_TIMES: 3 # 验证码识别失败重试次数

  LFLAG: '$<' # 左标志符号
  RFLAG: '>$' # 右标志符号
  SSL_VERIFY: FALSE # requests verify配置,默认即可

  CAPTCHA_REGEX: '.*(\w{4})' # 对ocr识别的结果进行提取 例如 .*(\w{4}) .*(\d{4}) (.*?) ......
  CAPTCHA_REGEX_GETVALUE_INDEX: 1 # 搭配CAPTCHA_REGEX使用,获取其正则表达式结果位置,从1开始

target:
  BLAST: blast.txt # 爆破的请求文本文件,默认即可
  CAPTCHA: captcha.txt # 验证码请求文本文件,默认即可
  CAPTCHA_LENGTH: 4 # 验证码位数,用于鉴别ocr识别结果准确与否 例如4 6...... 设置为0的话则为不验证验证码位数
  CAPTCHA_DATATYPE: CUSTOM # 验证码返回数据类型,可选择 原始图片:RAW base64编码:BASE64 自定义获取数据:CUSTOM
  CAPTCHA_CUSTOM_GETFLAG: 'code"\:"(.*?)"' # 搭配CAPTCHA_DATATYPE值为CUSTOM使用,正则表达式提取数据
  CAPTCHA_ID_INDEX: 4 # 验证码id位置,标志位从1开始
  CAPTCHA_ID_GETFLAG: '"codeId"\:"(.*?)"' # 提取验证码id的正则表达式
  CAPTCHA_INDEX: 3 # 验证码的位置,标志位从1开始
  WORDDICT_LIST: # 字典设置,需要注意顺序与BLAST文件中标记的顺序对应
    - 
      file: /Users/AbelChe/SecTools/worddicts/fuzzDicts/userNameDict/top500.txt # 字典文件位置
      plugin: # payload插件配置 数组格式 留空即为使用字典原始数据
        - ['upper']
    - 
      file: /Users/AbelChe/SecTools/worddicts/Blasting_dictionary/top100password.txt # 字典文件位置
      plugin: # payload插件配置 数组格式
        - ['md5'] # 格式为[插件名称(与plugins目录下文件名称对应), 参数1, 参数2, ......] 参数要与插件代码中的args=[]对应, 映射关系为 args=[参数1, 参数2, ......]
        - ['suffix', 'xxxxxxxxxx']
  SSL: False # 使用https与否
  CAPTCHA_ERROR_FLAG: # 判断验证码错误的文本标志,正则表达式
    - 验证码错误
    - 请输入正确验证码
    - 验证码异常
  CAPTCHA_ERROR_CODE: # 判断验证码错误的状态码
    - 500
    - 502
    - 403
  LOGIN_ERROR_FLAG: # 判断认证失败的标志,正则表达式
    - 账号不存在或密码错误
  LOGIN_ERROR_CODE: # 判断认证失败的状态码
  LOGIN_SUCCESS_FLAG: # 判断登录成功的文本标志,正则表达式
    - 登录成功
  LOGIN_SUCCESS_CODE: # 判断登录成功的状态码

关于插件:

类似burp爆破的payload processing,可以自定义,使用方法见上方target.WORDDICT_LIST的解释,插件目录为plugins/

自定义插件:

如下代码为添加前缀(如果你写过sqlmap tamper插件,那你也应该会写这个):

class PayloadProcessor: # 类名称不要更改
    name = __name__ # 不用修改
    description = '添加前缀' # 插件描述
    def __init__(self, payload, args=[]): # 不用修改
        self.payload = payload # 不用修改
        self.args = args # 不用修改 从config.yml的target.WORDDICT_LIST[1].get('plugin')[1]传进来的, 故这里args值为['XXXXXX']

    def __str__(self): # 不用修改
        return self.name # 不用修改

    def genterPatload(self): # 不用修改
        #>>>>>>>>>>>>自定义代码段>>>>>>>>>>>>>
        try:
            # return 返回payload字符串即可
            return self.args[0] + self.payload
        except Exception as e:
            print(e)
        #<<<<<<<<<<<<自定义代码段<<<<<<<<<<<<<
  1. 启动

需要python>=3.7

python BlastWithCaptcha.py
  1. 结果

如果有爆破成功的,会保存到BlastWithCaptchaResult.txt

类型1 session验证验证码

配置

参考使用方法-初始

效果

类型2 带有id的验证码

配置

以如下数据包为例:

  • captcha.txt

Connection: close

{}
