Scalayzer - a portable tool for vulnerability analysis in scala.

In recent years, the Java Virtual Machine (JVM) has become an engaging target for a multitude of functional programming languages, one of which is Scala. However, while the Scala compiler emits plain Java bytecode, the core APIs and security features of Scala programs are not necessarily similar to those of Java programs. Thus, we aim to complement a real-world vulnerability analysis with several standard Scala applications to evaluate the security issues in the language ecosystem using VM-independent metrics subsequently. In this regard, we introduce Scalayzer as a portable vulnerability analyzer that works based on a dynamic taint analysis system (DTA) for identifying various vulnerabilities and security issues in real-life Scala applications. To demonstrate the usefulness of our approach, we evaluated Scalayzer on a real-world security benchmark suite, which includes several popular projects, such as Play Framework, Akka, and Lift. Our tool could successfully identify 29 actual security violations in the benchmark suite.
