Researchers have introduced a novel type of adversarial example that, unlike typical attacks, uses large, visible perturbations that fool AI models while remaining recognizable to humans. This new method was tested on datasets like MNIST, CIFAR-10, and ImageNet, revealing a significant gap where models maintain high accuracy while human recognition drops considerably. Standard out-of-distribution detection methods failed to identify these examples, though a feature-space Mahalanobis detector was effective, albeit vulnerable to adaptive attacks. Existing defenses, including adversarial training, did not effectively mitigate the attack's success. AI
