Poison to Detect: Detection of Targeted Overfitting in Federated Learning
A novel detection method uses targeted poisoning signals to reveal orchestrator-driven privacy attacks in federated learning — relevant for enterprises adopting FL as a privacy-enhancing technology.

arXiv:2509.11974v2 Announce Type: replace Abstract: Federated Learning (FL) enables collaborative model training among clients without centralising data, making it a widely adopted privacy-enhancing technology (PET). Despite its privacy benefits, FL remains vulnerable to orchestrator-driven privacy attacks. In this paper, we study an underexplored threat in which a dishonest orchestrator intentionally manipulates the aggregation process to induce targeted overfitting in local models of specific
Editorial Analysis
Framed for the Security Researcher desk
The paper addresses the under-explored threat of a malicious orchestrator in federated learning, proposing a poisoning-based detection method — a novel angle for privacy-enhancing technology research.
If your research involves federated learning, evaluate the proposed detection technique against orchestrator-driven privacy attacks in your experimental setup.
