AI researchers demonstrate 100% success rate in bypassing online CAPTCHAs | Tom's Hardware


reCAPTCHAv2, anyway — newer CAPTCHA methodologies may still work, for now.

Per a research paper appropriately titled " Breaking reCAPTCHAv2" submitted to arXiv on September 13, usage of the existing You Only Look Once (YOLO) object recognition model after training it with 14,000 labeled traffic images enabled it to defeat reCAPTCHAv2 with a 100% success rate. As it turns out, Google's reCAPTCHAv2 is actually a bit outdated compared to reCAPTCHAv3, which uses other metrics to determine whether a user is human or not rather than directly testing them with image recognition challenges... unless the web host chooses to enable the feature. As the conclusion of the original paper says, "By conducting systematic experiments, we have shown that automated systems using advanced AI technologies, such as YOLO models, can successfully solve image-based captchas.
