FDIFormer:Protocol-Aware Transformer Learning for False Data Injection Attack Detection in Smart Grid Networks
Sandara Sathsarani Wijethunga, Muneeb Ul Hassan, Nasrin Sohrabi
Smart grids use communication networks and intelligent electronic devices for reliable, automated power system operation. As these systems become more interconnected, they are incr…
Multi-Round Visibility: A Post-Consensus Ordering Layer for DAG-Based BFT
Pengkun Ren, Dong Hai, Nasrin Sohrabi +1
Directed acyclic graph (DAG)-based Byzantine Fault-Tolerant (BFT) protocols achieve high throughput by decoupling dissemination from agreement and allowing many vertices to be comm…
Evaluating the Vulnerability Landscape of LLM-Generated Smart Contracts
Hoang Long Do, Nasrin Sohrabi, Muneeb Ul Hassan
Large language models (LLMs) have been widely adopted in modern software development lifecycles, where they are increasingly used to automate and assist code generation, significan…
How To Cook The Fragmented Rug Pull?
Minh Trung Tran, Nasrin Sohrabi, Zahir Tari +1
Existing rug pull detectors assume a simple workflow: the deployer keeps liquidity pool (LP) tokens and performs one or a few large sells (within a day) that collapse the pool and…
Proof-Carrying Fair Ordering: Asymmetric Verification for BFT via Incremental Graphs
Pengkun Ren, Hai Dong, Nasrin Sohrabi +2
Byzantine Fault-Tolerant (BFT) consensus protocols ensure agreement on transaction ordering despite malicious actors, but unconstrained ordering power enables sophisticated value e…
Slow is Fast! Dissecting Ethereum's Slow Liquidity Drain Scams
Minh Trung Tran, Nasrin Sohrabi, Zahir Tari +3
We identify the slow liquidity drain (SLID) scam, an insidious and highly profitable threat to decentralized finance (DeFi), posing a large-scale, persistent, and growing risk to t…
