Amazon WAF Captcha: History, Necessity and Vulnerabilities



In the digital era where technology continues to advance, cybersecurity is becoming increasingly important. One of the key components of web application security is protection against automated attacks such as DDoS or brute force. Captcha (Completely Automated Public Turing test to tell Computers and Humans Apart) is one of the methods used to protect against such attacks. In this article, we will look at the Amazon WAF captcha, find out who created it and when, look at the history of the captcha, and also discuss the difficulties of bypassing this technology.

1. Captcha: Brief overview and necessity
Captcha is a test that allows you to distinguish computers from people. It requires the user to complete a specific task or solve a simple puzzle to confirm they are a human and not a bot or script. The captcha was introduced to prevent automated attacks such as spam, brute force or DDoS. It serves to ensure the security and preservation of website resources.

2. Amazon WAF captcha: Creation and development
Amazon WAF (Web Application Firewall) is a service provided by Amazon Web Services (AWS) that offers tools to protect web applications from malicious requests and attacks. The Amazon WAF Captcha was developed internally by Amazon to provide an extra layer of security when using this service.

Captcha history:
The concept of captcha was first proposed by Louis von Ahn in 2000. He suggested using the problem of recognizing characters in an image, which computers of the time could not solve efficiently, to distinguish people from bots. This prevented automatic registration and other forms of abuse.

3. Necessity of Amazon WAF captcha:
Amazon WAF captcha is one of the mechanisms to protect web applications from automated attacks that can bypass standard traffic filtering methods. It helps prevent DDoS attacks, brute force attempts, spam, or unauthorized requests that can compromise the security and availability of web resources.

4. Difficulty of bypassing Amazon WAF captcha
Bypassing captcha is a difficult task because it requires a high degree of automation and intelligence. In the case of Amazon WAF captcha, it can be even more difficult to bypass, as the service is developed and maintained by Amazon, which is actively working on updates and improvements to its security systems. However, as with any technology, absolute protection cannot be guaranteed. Some advanced captcha bypass techniques may involve using machine learning, image recognition algorithms, or crowdsourcing to solve the problem.


Amazon WAF captcha is an effective way to protect web applications from automated attacks. It helps prevent DDoS attacks, brute force attempts, and other forms of abuse. While bypassing the Amazon WAF captcha is challenging, as technology advances, new attack methods may emerge. Therefore, it is important that companies providing such services constantly develop and improve their security systems to minimize vulnerabilities and ensure reliable protection of web resources.

your tutorial is well done to configure some functions to get a solution from 2Captcha.
Token and Voucher are obtained. But then what??

from other sources, it seems: need to create a cookie and then refresh the page but if you guys could put an example on your website it would be great.

thank you
