Researchers have developed a new defense mechanism called DF-CAPTCHA to combat sophisticated social engineering attacks that utilize real-time deepfakes. This system actively challenges callers with simple tasks that are easy for humans but difficult for current deepfake technology to replicate convincingly. DF-CAPTCHA evaluates responses based on realism, identity consistency, task completion, and response time, demonstrating significantly improved detection accuracy across both audio and video modalities compared to passive methods.
