Greetings, dear friends! We are all active users of social networks - some use them to communicate and search for information, while others try to use these platforms to earn money . However, regardless of what goals each of us pursues when entering a social network, we all, one way or another, have to deal with such an unpleasant thing as captcha. Agree, sometimes this set of characters interferes with your work so much that you want to give up everything and just close the browser. Today we will talk about how to remove the captcha and thereby save yourself from the need to waste time deciphering the codes.
Captcha: what is it?
So, a captcha is nothing more than a special picture containing a verification code to determine who is trying to perform a certain action on the network - a person or a robot. Most often, they offer to decrypt the code in cases where the same request is executed multiple times on the service. For example, search engines like Yandex or Google regularly offer us to decipher captcha when we ask them the same questions. Captcha cannot be called a rare guest in the environment of scripts: parsers, clickers, posters, and so on.
The main task of captcha is to prevent automated actions by robots . To weed out bots, services ask users to unravel the code encrypted in an ornate design. Only real users can cope with this goal; bots, alas, cannot do this. That is why, when working with scripts, captcha becomes a real problem that does not allow you to interact with a large amount of data. However, do not despair and give up. Every problem can be solved , and entering captcha is no exception.
How to remove captcha in Yandex?
The very first reason why this happens turned out to be banally simple. You have an ad blocking add-on installed in your browser. Something like AdBlock, or, if you use Yandex Browser, then this is most likely Adguard. What’s interesting is that it was the browser developers themselves who introduced AdGuard into it (why did they do it then?).
At the same time, I have had it for several years, along with the blocker. I encountered this problem about 1.5 months ago. I constantly entered captcha, mainly on the Yandex Wordstat service. I kept trying to figure out how to solve this problem, but I just didn’t get around to it.
Why does captcha appear?
As you know, in order to get rid of a disease, you need to know the cause of its occurrence. This rule also works in the case of captcha: in order to get rid of constantly pop-up windows with an encrypted code, we need to understand why the system is so zealously trying to check our “humanity”.
The thing is that identical actions performed one after another arouse suspicion among sites. Therefore, they strive to weed out those performed by robots.
For example, your attempt to send messages containing the same information to your friends is regarded by the social network as spam mailing. That is why VKontakte requires us to perform captcha recognition and confirm that this action was performed by a living person. If the distribution of messages does not stop, the system may even temporarily block your account.
You also have to deal with pop-up windows in cases where the social network’s security system decides to check whether you are using any prohibited programs to promote a group in contact or promote your own page. In this case, we are talking about special software that can automatically generate likes, send out invitations to friends, and so on. Such programs include the popular brobot and sobot , which are actively used to create popular communities and public pages. Just imagine what a dump VKontakte would become if it didn’t filter out hacking, advertising and spam!

Getting the field name
How to hack: just take the name of the captcha field from the code and use the program to intercept its value if it never changes.
How to protect yourself: use a dynamic field name, that is, it changes every time. It must be encrypted so that other programs cannot read it and receive a response. The decryption key will be located on the server; it cannot be obtained without access to the server script.
For example, a captcha is stored in the Captcha field. Then it's very easy to create a program that will read the value from it. You can select a name manually or use the databases of the most popular ones, which are stored in the public domain. However, if the name is constantly called differently and not just a word, but for example, a sequence of letters “fghtn” or “qpvbn”, then it will be more difficult to track it. And the most secure option: encrypt this sequence.
Learning to remove captcha
I am sure that most of you are now seriously puzzled about how to bypass the VKontakte captcha. Unfortunately, it is currently impossible to ignore entering a code . Technologies that protect the service by decrypting the character set are a mandatory security measure for a social network that you cannot hide or simply remove.
All you can do to reduce the frequency of encounters with an intrusive code is to provide VKontakte with maximum information about yourself by filling out the appropriate fields in the user profile. The more “human” your page is, the less often you will have to perform captcha recognition. Make sure that your social network page is linked to your email and real mobile number.
Setting up a VK profile
To protect yourself from possible hacking of your VKontakte page, I would recommend that you visit the “ Security ” tab, which is located in the “ My Settings ” section. Here you can connect the most powerful and reliable protection system, in the form of SMS confirmation codes sent to your specified mobile phone. In addition, I would like to draw your attention to the “ Activity History ” field.
If your account ends up in the hands of fraudsters, you will find out about this by checking the “ Activity History ”. If in the list of addresses you find third-party IPs and browsers that you have never used, this means that your account has been hacked and, most likely, was used for spam mailing. To correct this situation, you should “ End all sessions ” except the current one you are in, and then change the access password to your profile.
As for how to remove the captcha completely, here you have no choice but to unravel the encrypted set of symbols and enter it into a special field located next to the picture. Agree that we do not always have the ability to recognize captcha in real time. This is especially problematic in cases where we run a script and perform large volumes of work. As soon as search engines notice multiple requests, we will immediately begin to deal with captchas that pop up again and again.
This problem is very close to webmasters and those who actively work with posters, spammers and other automated programs. To get rid of annoying codes that interfere with your work, you can use the help of captcha recognition services.
The reason for spam and what to do to prevent captcha from annoying ordinary users
Most often, it is feedback forms that are spammed, since the purpose of this attack is to send an advertising-type message to the site owner. Spam pours in bags directly to the recipient, sometimes even bypassing the captcha by guessing. Extremely annoying and malicious advertisers do not hesitate to work on the weekend: by Monday they can drop several hundred letters into the mailbox.
The negative consequences of this can be not only the loss of time sorting mail. In the process of separating the grains from the husks, you may inadvertently remove an important letter. The worst thing is that there is a real chance of getting blacklisted by the hosting provider on whose site your mailbox is located.
It should be noted that forms are besieged not just by spammers, but also by doorway developers who do not distinguish the feedback form from the message or comment form. Therefore, everything falls under spam. Disabling captcha means getting rid of the protection, so before doing this, think about whether you need it.
To protect your website from spam attacks, but at the same time not irritate ordinary users with constant captchas, you can use the so-called invisible field. To do this, you need to create the simplest input field, but at the same time, hide it through the CSS system. Then an ordinary user simply will not have to fill it out, because this code will be invisible to his eye, but a spam bot will not be able to pass such a check.

Popular automatic captcha recognition services
Today on the Internet you can find many sites that offer their captcha entry services for money. Some of the most popular services in the Runet segment are rucaptcha and anti-captcha. I propose to examine each of them in more detail:
- anti-captcha – many people know this site as anti-captcha. The service has been working stably for 10 years. Here you have to pay in dollars . Every thousand codes solved will cost you 40 cents. You will learn how to work with this site a little later.
- rucaptcha is a popular service where captcha solving is done manually. With its help, you can provide automatic captcha entry on your projects. To do this, you need to have a special key that will be sent through the service to real people working on the site for its subsequent recognition. The cost of such a service is only 40 rubles for every thousand pictures solved. The principle of operation of the service is quite simple: real people register on the site and earn money by entering captcha. That is, over the course of a day, more and more new orders for deciphering codes come to the site, and ordinary Internet users solve them and receive a monetary reward for this

How to bypass captcha using high technology
We have looked at the weak points of CAPTCHA implementations, which are security holes and are the most common in practice. However, in practice, even the most impeccable captchas are sometimes unable to protect the resource that uses them from hacker attacks.
These cases of captcha hacking are a direct consequence of modern progress and the level of development of computer technology, which, as we know, is not always used for good purposes.
So, how to avoid captcha using modern technology?
Bypass captcha using OCR
OCR (Optical Character Recognition) is a technology for recognizing printed or typewritten text for its further use in electronic format. The most well-known software that implements this technology is Adobe FineReader.
It is successfully used in creating automatic captcha entry programs that successfully recognize and solve graphic captchas, to complete which you need to enter the sequence of characters shown in the picture.
Hackers, naturally, do not use Adobe FineReader (although there may be some
