Google’s new reCAPTCHA has a dark side

Khormaee won’t share what signals Google uses to determine these scores because he says that would make it easier for scammers to imitate benign users, but he believes that this new version of reCaptcha makes it incredibly difficult for bots or Captcha farmers—humans who are paid tiny amounts to break Captchas online—to fool Google’s system. Google is also now testing an enterprise version of reCaptcha v3, where Google creates a customized reCaptcha for enterprises that are looking for more granular data about users’ risk levels to protect their site algorithms from malicious users and bots. According to two security researchers who’ve studied reCaptcha, one of the ways that Google determines whether you’re a malicious user or not is whether you already have a Google cookie installed on your browser.
