Researchers have developed new methods to enhance distributed backdoor attacks in federated learning, making them more stealthy and efficient. One approach, Fractal-Triggerred Distributed Backdoor Attack (FTDBA), uses fractal properties to strengthen sub-triggers, requiring less poisoned data while reducing detection rates. Another method, a fine-grained distributed backdoor attack framework (FDBA), employs dynamic trigger generation and embedding vector optimization to achieve similar goals with fewer poisoned samples. Additionally, a lattice-based reconstruction attack has been proposed that exploits the structural leakage in decentralized federated learning's secure aggregation to reconstruct individual model updates and potentially private training data.
