Captcha breaking refers to the process of bypassing or circumventing the security measure known as CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart). This is typically done by using automated software or services to solve the challenges presented by CAPTCHA, which are designed to distinguish between human users and bots. The goal of captcha breaking is to gain access to restricted content or perform automated actions, often for malicious purposes. This practice undermines the effectiveness of CAPTCHA in protecting websites and online services from spam, bots, and other forms of automated abuse.
