Research: Hybrid VLM-YOLO system solves CAPTCHAs with learning, raising security concerns

New research demonstrates a CAPTCHA-solving system that pairs a fine-tuned YOLOv8 detector with an open-weight vision-language model, using confidence-based routing to improve with exposure. This marks a shift from static solvers to adaptive ones, potentially undermining CAPTCHA-based bot defenses. The effectiveness against major CAPTCHA providers and real-world deployment remain unverified.
