How to solver Captcha With Python and NextCaptcha

gurakuqienrik6 — Tue, 19 Mar 2024 04:35:35 +0000

CAPTCHA, short for Completely Automated Public Turing Test to Tell Computers and Humans Apart, has long been a contentious element in user interfaces. It aims to thwart automated bots but often proves to be an annoyance for users. Over time, CAPTCHA tests have become more complex, yet methods for bypassing them have evolved as well. In this tutorial, we'll explore how to circumvent CAPTCHA using Python and NextCaptcha. This tool allows developers to automate solving CAPTCHA challenges, enhancing user experiences while maintaining security against bots and scripts.

What are CAPTCHAs?

CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart." It is a type of challenge-response test used in computing to determine whether or not the user is human. CAPTCHAs are typically used to prevent automated programs, often referred to as bots or spambots, from performing certain actions on websites, such as creating accounts, submitting forms, or accessing restricted content.

CAPTCHAs usually involve presenting the user with a task that is easy for humans to solve but difficult for automated programs to complete accurately. This task could be identifying distorted letters or numbers, recognizing objects in images, solving puzzles, or performing other simple tasks.

The purpose of CAPTCHAs is to ensure that interactions on websites are conducted by real human users rather than automated scripts or bots, thus helping to prevent spam, fraud, and other malicious activities.

CAPTCHA's Shortcoming

While CAPTCHAs serve the purpose of distinguishing humans from bots, they also come with several downsides:

Accessibility Issues: CAPTCHAs can pose significant challenges for users with disabilities, particularly those with visual impairments who may have difficulty deciphering distorted text or identifying objects in images. This can result in excluding certain individuals from accessing or interacting with websites.
User Frustration: CAPTCHAs can be frustrating for users, especially when they are overly complex or difficult to solve. This frustration can lead to a poor user experience and may deter users from engaging with a website or completing desired actions.
Effectiveness Decline: As CAPTCHA-solving technology advances, some bots and automated scripts have become more adept at circumventing CAPTCHA challenges. This diminishes the effectiveness of CAPTCHAs in preventing automated activities and spam.
Impact on Conversion Rates: Overly intrusive or cumbersome CAPTCHAs can negatively impact conversion rates on websites, such as e-commerce platforms or registration forms. Users may abandon the process altogether if they find the CAPTCHA too burdensome, resulting in lost potential customers or users.
Maintenance Overhead: Websites that implement CAPTCHAs need to continuously monitor and update their CAPTCHA mechanisms to stay ahead of evolving bot technologies. This incurs maintenance overhead and additional costs for website operators.
Security Risks: While CAPTCHAs are designed to enhance security by distinguishing humans from bots, they can also introduce security risks if implemented incorrectly. For example, poorly designed CAPTCHAs or third-party CAPTCHA services may inadvertently expose websites to vulnerabilities or privacy breaches.

Overall, while CAPTCHAs are a commonly used tool for combating automated activities and spam, they come with trade-offs that website operators must consider carefully to balance security, usability, and accessibility.

What is NextCaptcha

NextCaptcha is efficient and reliable captcha solver solution. NextCaptcha employs two primary API endpoints to address a range of CAPTCHA styles. The initial request transmits the necessary data for CAPTCHA resolution and yields either a request ID or a base64-encoded image for image CAPTCHAs. Upon acquiring the request ID, subsequent requests are made to the designated endpoint, which is periodically queried until the solution is provided.

Setup

We need to sign up on NextCaptcha's platform to create an API Key for making requests.

Copy API Key

As shown below, we now have access to the API Key on our dashboard, which we will utilize later in this tutorial.

Step 1 - Create project and initialize

Create project and install nextcaptcha-python sdk

mkdir solver-recaptcha-python-demo
cd solver-recaptcha-python-demo
pip install nextcaptcha-python

Step 2 - Create a file

Create entry file

touch index.py

Step 3 - Demo Site

We'll use official demo website[] to see whether we can bypass the captcha on their submit form.

First, we need to obtain the site/captcha key, which will be incorporated into our request body when sending a request from our application. Let's navigate to the Element tab, depicted below, to copy the key.

or you can input this code in console to get the element attr

$('[data-sitekey]')

Step 4 - Demo

We successfully retrieved the site key in Step 3, so let's head over to our application to submit the infomation and bypass the captcha, which is what we set out to accomplish in this article.

In index.py, let's create a function with the required data to request NextCaptcha to bypass captcha on user submit action as shown in the snippet below:

from nextcaptcha import NextCaptchaAPI

// Get access to solver by passing your API key
CLIENT_KEY = "YOUR_CLIENT_KEY"
WEBSITE_URL = "https://www.google.com/recaptcha/api2/demo"
WEBSITE_KEY = "WEBSITE_KEY"

def main():

    api = NextCaptchaAPI(client_key=CLIENT_KEY)
    result = api.recaptchav2(website_url=WEBSITE_URL, website_key=WEBSITE_KEY)

    if result["status"] == "ready":
        print(f"reCAPTCHA solved: {result['solution']}")

        response = requests.post("https://www.google.com/recaptcha/api2/demo", data={
            "g-recaptcha-response": result['solution']['gRecaptchaResponse']
        })
        print(f"submit bypass: {response.text}") # it will show Verification Success... Hooray!

    else:
        print(f"Failed to solve reCAPTCHA: {result['error']}")

if __name__ == "__main__":
    main()

In the snippet above

We get access to the solver by passing our API key
We send the captcha solution and other data to the server using pythons sdk
We then log the response and wait for NextCaptcha

To run this

python index.py

It will return the solution almost immediately then we could sumit with the return gRecaptchaResponse.

Voila 🥳 We successfully bypassed the captcha during the registration, and now we have a token to log in, as shown above. Let us proceed to submit.

Conclusion

In this article, we've effectively learned how to bypass CAPTCHA and successfully log in, a method applicable to any website employing CAPTCHA security measures.

How to Solve Captcha with Nodejs

gurakuqienrik6 — Thu, 14 Mar 2024 01:59:30 +0000

About reCAPTCHA v2

reCAPTCHA v2 is a CAPTCHA system developed by Google that aims to help websites distinguish between human users and automated programs (such as bots). It verifies a user's human identity by requiring them to click a checkbox before completing actions like submitting a form or logging in. reCAPTCHA v2 determines if a user is a genuine human by analyzing information such as their clicking behavior and browsing patterns.

Type of reCAPTCHA v2

Checkbox

As shown in the image, the "I'm not a robot" checkbox requires the user to click the checkbox indicating that the user is not a robot. This will either immediately pass the user (without a CAPTCHA) or challenge them to verify they are human.

Invisible

As shown in the image, the invisible reCAPTCHA badge does not require the user to click a checkbox. Instead, it is directly invoked when the user clicks an existing button on the site, or it can be invoked via the JavaScript API. After the reCAPTCHA verification is completed, the integration requires a JavaScript callback. By default, only the most suspicious traffic will be prompted to solve a CAPTCHA.

In this article, we will unveil the mystery of CAPTCHAs and walk through the process of building a simple reCAPTCHA v2 solver using Node.js, step by step.

Environment Setup

First, make sure you have Node.js installed on your system. Additionally, install the required libraries:

npm install axios
npm install cheerio

When the target webpage is a static page, we directly use axios to download the relevant webpage, and then use cheerio to parse the webpage and extract the relevant data needed to bypass reCAPTCHA v2.

Before we start the actual bypass, we need to register on the NextCaptcha website. After registering an account, you can obtain an account key from the backend, which is the clientKey. Save it for later use.

After obtaining the relevant clientKey, we will formally begin our journey of bypassing reCAPTCHA v2.

Here we will use the official Demo as an example, and the target URL is https://www.google.com/recaptcha/api2/demo

Obtain the HTML of the webpage

const axios = require('axios');

async function getPageData(url) {
    try {
        const data = await axios.get(url)
        return data.data;  
    }  catch (e) {
        console.error('getPageData error', e.message);
        return null;
    }
}

getPageData('https://www.google.com/recaptcha/api2/demo');

Obtain the reCAPTCHA related parameters

const cheerio = require('cheerio');

function parserData(html) {
    try {
        const $ = cheerio.load(html);

        return $('[data-sitekey]').data('sitekey')

    } catch (e) {
        console.error('parserData error', e.message);
        return null;
    }
}

Construct the bypass CAPTCHA request

const axios = require('axios');

async function createCaptchaTask(url, siteKey, isInvisible) {
    try {
        const data = await axios.post('https://api.nextcaptcha.com/createTask', {
            "clientKey": "clientKey", // clientKey from NextCaptcha dashboard
            "task": {
                type: "RecaptchaV2TaskProxyless",
                websiteURL: url,
                websiteKey: siteKey,
                isInvisible
            }
        });
        return data.data;
    } catch (e) {
        console.error('createCaptchaTask error', e.message);
        return null;
    }
}

Obtain the CAPTCHA solver task result

const axios = require('axios');

async function sleep(time = 500) {
    return new Promise((resolve) => {
        setTimeout(() => {
            resolve();
        }, time)
    })
}
async function getTaskResult(taskId) {
    try {
        const data = await axios.post('https://api.nextcaptcha.com/getTaskResult', {
            "clientKey": "clientKey", // clientKey from NextCaptcha
            taskId
        });
        if (data.data.status === 'processing') {
            await sleep();
            return getTaskResult(taskId)
        } else {
            console.error('createCaptchaTask errorCode', data.data.errorCode);
            console.error('createCaptchaTask errorDescription', data.data.errorDescription);
            return null;
        }
    } catch (e) {
        console.error('createCaptchaTask error', e.message);
        return null;
    }
}

Final Code

const axios = require('axios');
const cheerio = require('cheerio');

async function getPageData(url) {
    try {
        const data = await axios.get(url)
        return data.data;  
    }  catch (e) {
        console.error('getPageData error', e.message);
        return null;
    }
}

function parserData(html) {
    try {
        const $ = cheerio.load(html);

        return $('[data-sitekey]').data('sitekey')

    } catch (e) {
        console.error('parserData error', e.message);
        return null;
    }
}

async function createCaptchaTask(url, siteKey, isInvisible) {
    try {
        const data = await axios.post('https://api.nextcaptcha.com/createTask', {
            "clientKey": "clientKey", // clientKey from NextCaptcha dashboard
            "task": {
                type: "RecaptchaV2TaskProxyless",
                websiteURL: url,
                websiteKey: siteKey,
                isInvisible
            }
        });
        return data.data;
    } catch (e) {
        console.error('createCaptchaTask error', e.message);
        return null;
    }
}

async function sleep(time = 500) {
    return new Promise((resolve) => {
        setTimeout(() => {
            resolve();
        }, time)
    })
}

async function getTaskResult(taskId, tryTimes = 60) {
    try {
        const data = await axios.post('https://api.nextcaptcha.com/getTaskResult', {
            "clientKey": "clientKey", // clientKey from NextCaptcha
            taskId
        });
         if (data.data.status === 'ready') {
            return data.data;
        } else if (data.data.status === 'processing' && tryTimes >= 0) {
            await sleep();
            return getTaskResult(taskId)
        } else {
            if (tryTimes < 0) {
                console.error('getTaskResult out of time');
            } else {
                console.error('getTaskResult errorCode', data.data.errorCode);
                console.error('getTaskResult errorDescription', data.data.errorDescription);
            }
            return null;
        }
    } catch (e) {
        console.error('getTaskResult error', e.message);
        return null;
    }
}

async function mian() {
    const url = 'https://www.google.com/recaptcha/api2/demo'
    const html = await getPageData(url);
    const sitekey = parserData(html);
    console.log(sitekey)
    const task = await createCaptchaTask(url, sitekey, false);
    const result = await getTaskResult(task.taskId);
    console.log(result)
}

mian()

The gRecaptchaResponse in the result obtained in the last step is the token solved by reCAPTCHA v2. We can use this token to submit it to the relevant interface of the website, so that we have completed the entire process of CAPTCHA bypass.

Conclusion

Although the verification code service of NextCaptcha is charged and each verification requires a certain amount of points, its price is relatively affordable compared to other similar services on the market. More importantly, its recognition accuracy is very high and it can crack the verification codes of many websites.
