The developers of hCaptcha, in turn, reported that they have already implemented in their CAPTCHA methods proposed by experts to mitigate the consequences of such attacks. In this post, we will learn how this captcha test works and what can we do to pass it without having to answer whats inside the pictures test. The company said that “hCaptcha is just one of various methods Cloudflare uses to detect and potentially block automated traffic.” Cloudflare claims that they have additional systems to detect automated attacks, and there is no need to worry about a new attack method. The Record turned to Cloudflare for comment as the University of Louisiana’s findings alarmed many site owners. The authors of the report warned that the method they developed could help attackers bypass hCaptcha on live sites and carry out automated attacks, including posting spam on forums, scraping content, and so on. Moreover, the attack could have worked even faster if the researchers replaced their own image classifier with services such as Google Cloud Vision, Amazon Rekognition and Microsoft Azure Cognitive Vision. ![]() ![]() Researchers write that their attack works with an accuracy of 95.93%, and on average it takes only 18.76 seconds to crack hCaptcha. Go to Browser settings and in the search box type proxy then select open proxy settings > In connection tabs > Lan settings > Tick Use a proxy. ![]() Moreover, unlike other attacks on various CAPTCHA systems, this method does not require much computing power: the researchers’ equipment consisted of a simple Docker container running Ubuntu, with a tri-core processor and 2 GB of memory. Experts have developed an attack that uses browser automation tools, image recognition, image classifiers, and machine learning algorithms to download hCaptcha tasks, recognize image content, classify images, and then solve problems. In March 2021, researchers at the University of Louisiana at Lafayette presented a paper on a new hCaptcha bypass method that replaced reCAPTCHA in Cloudflare and Google last year.
