Timeout mechanisms are a useful feature for web applications. However, these mechanisms need to be used with care because, if used as-is, they are vulnerable to timing attacks. This paper focuses on internal timing attacks, a particularly dangerous class of timing attacks, where the attacker needs no access to a clock. In the context of client-side web application security, we present JavaScript-based...
In this paper we present a new technique able to recover behavioral design pattern instances which combines static analysis, based on visual language parsing, with dynamic analysis, based on source code instrumentation. In particular, the dynamic analysis is performed through the automatic instrumentation of the method calls involved in the candidate pattern instances identified during static analysis...
jPredictor is a tool for detecting concurrency errors in Java programs. The Java program is instrumented to emit property-relevant events at runtime and then executed. The resulting execution trace is collected and analyzed by Predictor, which extracts a causality relation sliced using static analysis and refined with lock-atomicity information. The resulting abstract model, a hybrid of a partial...
