Concerned with Data Contamination? Assessing Countermeasures in Code Language Model
Jialun Cao, Wuqi Zhang, Shing-Chi Cheung
Various techniques have been proposed to leverage the capabilities of code language models (CLMs) for SE tasks. While these techniques typically evaluate their effectiveness using…
Combatting Front-Running in Smart Contracts: Attack Mining, Benchmark Construction and Vulnerability Detector Evaluation
Wuqi Zhang, Lili Wei, Shing-Chi Cheung +4
Front-running attacks have been a major concern on the blockchain. Attackers launch front-running attacks by inserting additional transactions before upcoming victim transactions t…
Finding Deviated Behaviors of the Compressed DNN Models for Image Classifications
Yongqiang Tian, Wuqi Zhang, Ming Wen +4
Model compression can significantly reduce the sizes of deep neural network (DNN) models, and thus facilitates the dissemination of sophisticated, sizable DNN models, especially fo…
WFDefProxy: Modularly Implementing and Empirically Evaluating Website Fingerprinting Defenses
Jiajun Gong, Wuqi Zhang, Charles Zhang +1
Tor, an onion-routing anonymity network, has been shown to be vulnerable to Website Fingerprinting (WF), which de-anonymizes web browsing by analyzing the unique characteristics of…
Characterizing Transaction-Reverting Statements in Ethereum Smart Contracts
Lu Liu, Lili Wei, Wuqi Zhang +3
Smart contracts are programs running on blockchain to execute transactions. When input constraints or security properties are violated at runtime, the transaction being executed by…
