New GraphToxin Attack Reconstructs Deleted Data from GNNs

Researchers have developed GraphToxin, a novel attack capable of reconstructing entire unlearned graphs from graph neural networks (GNNs). This method goes beyond previous membership inference attacks by not only recovering deleted individual data but also sensitive information of their neighbors. GraphToxin utilizes a curvature matching module for fine-grained guidance and has demonstrated effectiveness in both white-box and black-box scenarios, highlighting the limitations of current graph unlearning verification standards. AI

IMPACT This research highlights significant vulnerabilities in current graph unlearning techniques, potentially impacting data privacy and security in AI systems that handle graph data.

    GraphToxin: Reconstructing Full Unlearned Graphs from Graph Unlearning

    arXiv:2511.10936v3 Announce Type: replace-cross Abstract: Graph unlearning (GU) has emerged as a promising solution to comply with "the right to be forgotten" regulations by enabling the removal of sensitive information upon request. However, this solution is not foolproof. The i…
