Leak and Learn: An Attacker's Cookbook to Train Using Leaked Data from Federated Learning

no code implementations26 Mar 2024 Joshua C. Zhao, Ahaan Dabholkar, Atul Sharma, Saurabh Bagchi

We demonstrate the effectiveness of both GI and LLL attacks in maliciously training models using the leaked data more accurately than a benign federated learning strategy.

The Resource Problem of Using Linear Layer Leakage Attack in Federated Learning

no code implementations CVPR 2023 Joshua C. Zhao, Ahmed Roushdy Elkordy, Atul Sharma, Yahya H. Ezzeldin, Salman Avestimehr, Saurabh Bagchi

We show that this resource overhead is caused by an incorrect perspective in all prior work that treats an attack on an aggregate update in the same way as an individual update with a larger batch size.

LOKI: Large-scale Data Reconstruction Attack against Federated Learning through Model Manipulation

1 code implementation21 Mar 2023 Joshua C. Zhao, Atul Sharma, Ahmed Roushdy Elkordy, Yahya H. Ezzeldin, Salman Avestimehr, Saurabh Bagchi

When both FedAVG and secure aggregation are used, there is no current method that is able to attack multiple clients concurrently in a federated learning setting.
