WebApr 20, 2024 · Hence, we consider a novel form of node injection poisoning attacks on graph data. We model the key steps of a node injection attack, e.g., establishing links between the injected adversarial nodes and other nodes, choosing the label of an injected node, etc. by a Markov Decision Process. WebGraph Neural Networks (GNNs) have achieved promising performance in various real-world applications. However, recent studies have shown that GNNs are vulnerable to …

WebApr 7, 2024 · State estimation plays a vital role in the stable operation of modern power systems, but it is vulnerable to cyber attacks. False data injection attacks (FDIA), one of the most common cyber attacks, can tamper with measurement data and bypass the bad data detection (BDD) mechanism, leading to incorrect results of power system state … WebFeb 3, 2024 · GraphQL injection attacks can lead to a few different scenarios: DoS (overloading the parser or resolver to a point they crash) Extract data Manipulate data dade county court map
TDGIA:Effective Injection Attacks on Graph Neural Networks
Webattack. Most previous attacks on Graph Neural Networks focus on node classification tasks, and all of them made non-practical assumptions on the attacking scenario. In this work, we will propose a non-targeted Hard Label Black Box Node Injection Attack on Graph Neural Networks, which to the best of our knowledge, is the first of its kind. Weba dense graph.
