reCAPTCHA V2 Invisibleの突破方法

Posted at
  1. ブラウザでデベロッパーコンソールを開き、data-sitekey属性を持つ要素を見つけます。

    <button class="g-recaptcha" data-sitekey="6LdO5_IbAAAAAAeVBL9TClS19NUTt5wswEb3Q7C5" data-callback="onSubmit" id="recaptcha">Check</button>
    
  2. sitekeypageurlAPIに送信します。

SDK を使用する場合 (推奨):

PHP
    // https://github.com/2captchacom/2captcha-php

    require(__DIR__ . '/../src/autoloader.php');

    $solver = new \TwoCaptcha\TwoCaptcha('YOUR_API_KEY');

    try {
        $result = $solver->recaptcha([
            'sitekey'   => '6LdO5_IbAAAAAAeVBL9TClS19NUTt5wswEb3Q7C5',
            'url'       => 'https://{{ hostname }}/demo/recaptcha-v2-invisible',
            'invisible' => 1,
        ]);
    } catch (\Exception $e) {
        die($e->getMessage());
    }

    die('Captcha solved: ' . $result->code);
Python
    # https://github.com/2captchacom/2captcha-python

    import sys
    import os

    sys.path.append(os.path.dirname(os.path.dirname(os.path.realpath(__file__))))

    from twocaptcha import TwoCaptcha

    api_key = os.getenv('APIKEY_2CAPTCHA', 'YOUR_API_KEY')

    solver = TwoCaptcha(api_key)

    try:
        result = solver.recaptcha(
            sitekey='6LdO5_IbAAAAAAeVBL9TClS19NUTt5wswEb3Q7C5',
            url='https://{{ hostname }}/demo/recaptcha-v2-invisible',
            invisible=1)

    except Exception as e:
        sys.exit(e)

    else:
        sys.exit('solved: ' + str(result))
Java
    // https://github.com/2captchacom/2captcha-java

    package examples;

    import com.twocaptcha.TwoCaptcha;
    import com.twocaptcha.captcha.reCAPTCHA;

    public class reCAPTCHAV2Example {
        public static void main(String[] args) {
            TwoCaptcha solver = new TwoCaptcha("YOUR_API_KEY");
            reCAPTCHA captcha = new reCAPTCHA();
            captcha.setSiteKey("6LdO5_IbAAAAAAeVBL9TClS19NUTt5wswEb3Q7C5");
            captcha.setUrl("https://{{ hostname }}/demo/recaptcha-v2-invisible");
            captcha.setInvisible(true);
            try {
                solver.solve(captcha);
                System.out.println("Captcha solved: " + captcha.getCode());
            } catch (Exception e) {
                System.out.println("Error occurred: " + e.getMessage());
            }
        }

    }
C#
    // https://github.com/2captchacom/2captcha-csharp

    using System;
    using System.Linq;
    using TwoCaptcha.Captcha;

    namespace TwoCaptcha.Examples
    {
        public class reCAPTCHAV2Example

                reCAPTCHA captcha = new reCAPTCHA();
                captcha.SetSiteKey("6LdO5_IbAAAAAAeVBL9TClS19NUTt5wswEb3Q7C5");
                captcha.SetUrl("https://{{ hostname }}/demo/recaptcha-v2-invisible");
                captcha.SetInvisible(true);
                try
                {
                    solver.Solve(captcha).Wait();
                    Console.WriteLine("Captcha solved: " + captcha.Code);
                }
                catch (AggregateException e)
                {
                    Console.WriteLine("Error occurred: " + e.InnerExceptions.First().Message);
                }
            }
        }
    }
Go
    // https://github.com/2captchacom/2captcha-go

    package main

    import (
        "fmt"
        "log"
        "github.com/2captcha/2captcha-go"
    )

    func main() {
        client := api2captcha.NewClient("API_KEY")
        cap := api2captcha.reCAPTCHA{
            SiteKey: "6LdO5_IbAAAAAAeVBL9TClS19NUTt5wswEb3Q7C5",
            Url: "https://{{ hostname }}/demo/recaptcha-v2-invisible",
            Invisible: true,
        }
        code, err := client.Solve(cap.ToRequest())
        if err != nil {
            log.Fatal(err);
        }
        fmt.Println("code "+code)
    }
C++
    // https://github.com/2captchacom/2captcha-cpp

    #include <cstdio>

    #include "curl_http.hpp"
    #include "api2captcha.hpp"

    int main (int ac, char ** av)
    {
    api2captcha::curl_http_t http;
    http.set_verbose (true);

    api2captcha::client_t client;
    client.set_http_client (&http);
    client.set_api_key (API_KEY);

    api2captcha::recaptcha_t cap;
    cap.set_site_key ("6LdO5_IbAAAAAAeVBL9TClS19NUTt5wswEb3Q7C5");
    cap.set_url ("https://{{ hostname }}/demo/recaptcha-v2-invisible");
    cap.set_invisible (true);

    try
    {
        client.solve (cap);
        printf ("code '%s'\n", cap.code ().c_str ());
    }
    catch (std::exception & e)
    {
        fprintf (stderr, "Failed: %s\n", e.what ());
    }

    return 0;   
    }

結果は次のようになります。

手動:

2.1 API URL: https://{{ hostname }}/in.phpにGETまたはPOSTリクエストを送信し、methoduserrecaptchaに設定して、前のステップで見つかった値をgooglekeyとして、フルページURLの値としてpageurlを提供します。 リクエストの例:

    `GET https://{{ hostname }}/in.php?key=YOUR_API_KEY&method=userrecaptcha&googlekey=6LdO5_IbAAAAAAeVBL9TClS19NUTt5wswEb3Q7C5&pageurl=http://{{ hostname }}/demo/recaptcha-v2-invisible`

2.1.1 何も問題がなければ、サーバーはキャプチャのIDを返します。

    `OK|2122988149`

それ以外の場合、サーバーは エラーコード を返します。

2.1.2 15-20秒後にGETリクエストを送信して結果を取得します。

    `GET https://{{ hostname }}/res.php?key=YOUR_API_KEY&action=get&id=2122988149`

CAPTCHAを突破済みの場合、サーバーは回答トークンで応答します。

    `OK|03AHJ_Vuve5Asa4koK3KSMyUkCq0vUFCR5Im4CwB7PzO3dCxIo11i53epEraq-uBO5mVm2XRikL8iKOWr0aG50sCuej9bXx5qcviUGSm4iK4NC_Q88flavWhaTXSh0VxoihBwBjXxwXuJZ-WGN5Sy4dtUl2wbpMqAj8Zwup1vyCaQJWFvRjYGWJ_TQBKTXNB5CCOgncqLetmJ6B6Cos7qoQyaB8ZzBOTGf5KSP6e-K9niYs772f53Oof6aJeSUDNjiKG9gN3FTrdwKwdnAwEYX-F37sI_vLB1Zs8NQo0PObHYy0b0sf7WSLkzzcIgW9GR0FwcCCm1P8lB-50GQHPEBJUHNnhJyDzwRoRAkVzrf7UkV8wKCdTwrrWqiYDgbrzURfHc2ESsp020MicJTasSiXmNRgryt-gf50q5BMkiRH7osm4DoUgsjc_XyQiEmQmxl5sqZP7aKsaE-EM00x59XsPzD3m3YI6SRCFRUevSyumBd7KmXE8VuzIO9lgnnbka4-eZynZa6vbB9cO3QjLH0xSG3-egcplD1uLGh79wC34RF49Ui3eHwua4S9XHpH6YBe7gXzz6_mv-o-fxrOuphwfrtwvvi2FGfpTexWvxhqWICMFTTjFBCEGEgj7_IFWEKirXW2RTZCVF0Gid7EtIsoEeZkPbrcUISGmgtiJkJ_KojuKwImF0G0CsTlxYTOU2sPsd5o1JDt65wGniQR2IZufnPbbK76Yh_KI2DY4cUxMfcb2fAXcFMc9dcpHg6f9wBXhUtFYTu6pi5LhhGuhpkiGcv6vWYNxMrpWJW_pV7q8mPilwkAP-zw5MJxkgijl2wDMpM-UUQ_k37FVtf-ndbQAIPG7S469doZMmb5IZYgvcB4ojqCW3Vz6Q`

CAPTCHAが未解決の場合、サーバーは「CAPCHA_NOT_READY」の結果を返します。 その後5秒以内にリクエストを繰り返してください。何か問題が発生した場合、サーバーは エラーコード を返します。

  1. デベロッパーコンソールで、id="g-recaptcha-response"textareaを見つけて、そこに受け取ったコードを置きます。次に、「確認」ボタンをクリックします。
