New attack embeds undetectable backdoors in neural networks

Researchers have developed a novel attack mechanism that can embed undetectable backdoors into modern neural networks, including ResNet and Vision Transformer architectures. This method exploits the inherent geometry of learned representations within the network's latent space, rather than introducing foreign structures. The attack achieves high success rates with minimal degradation to clean accuracy and proves resistant to standard post-training defenses, suggesting that cryptographic backdoor guarantees may be practically unattainable for current state-of-the-art models.
