Price manipulation is one of the most damaging vulnerability classes in decentralized finance (DeFi) protocols. Existing approaches mainly stop at warning generation or rely on rigid attack templates, and therefore struggle to determine whether a victim protocol is profitably exploitable under a concrete chain state. T...

Generating categorical graphs requires choosing node and edge types that form a coherent structure without depending on node order. Many graph generators encode categories as fixed one-hot vectors, which can impose an artificial geometry in which categories are equidistant. We propose Embedded Graph Flows (EGF), a gene...

SHAQ (shadow query generation), a semantic-decomposition and embedding-decoupling defense against EIAs, is proposed, which uses a generative language model to create diverse shadow queries that capture different semantic aspects of each document.

This work focuses on the early ChatGPT plugin ecosystem, which is in the original plugin store before the transition to the GPT Store, and probes domain reachability, residual configuration files, and API endpoint responses to identify backend services that standard probes miss.
The first large-scale, cross-platform study of plugins from five major web application marketplaces, covering domains from office productivity to software development, indicates that AI-assisted plugins face a range of emerging issues that negatively impact user experience and fail to comply with established AI ethics...
