Researchers have developed a new strategy called Augmented Model Manipulation (AugMP) to attack federated fine-tuning (FFT) of large language models (LLMs). This method uses graph representation learning to identify correlations in legitimate LLM updates, which then guides the creation of malicious updates. An iterative algorithm optimizes these malicious updates to embed adversarial objectives while appearing similar to benign updates, making them difficult to detect. Experiments show AugMP can significantly degrade global LLM accuracy and local agent performance while evading standard defense mechanisms. AI
