The study introduces Bad-Deepfake, a pioneering strategy targeting deepfake detectors with backdoor attacks. By exploiting vulnerabilities in detection systems, the authors achieve remarkable success rates against deepfake detectors. The research highlights the importance of trigger construction and sample selection for effective backdoor attacks.

Recent advancements in deep generative models have led to the creation of high-quality deepfakes that challenge the integrity of digital media. Despite efforts to develop robust detection mechanisms, vulnerabilities persist, especially against adversarial example attacks during testing phases. The study introduces "Bad-Deepfake," a novel approach using backdoor attacks to manipulate training data and achieve a 100% attack success rate against popular deepfake detectors.

The proliferation of deepfakes has raised concerns about disinformation and trustworthiness in digital content. Current research focuses on enhancing technologies to combat deceptive alterations through advanced methodologies centered around deep neural networks (DNNs). However, these methods are susceptible to adversarial attacks targeting neural networks directly, allowing forged images to evade detection mechanisms.

The study explores an innovative paradigm by integrating backdoor attacks into deepfake detection strategies. By clandestinely embedding hidden Trojans within DNNs during training phases, attackers can manipulate model predictions with specific triggers. This approach aims to address vulnerabilities in current detection systems and enhance defenses against sophisticated attacks.
