Vulnerabilities in browsers and their extensions have become the primary venue through which cyber criminals compromise the security of Web users and, ultimately, earn money
The browser has become the de facto platform for everyday computation and a popular target for attackers of computer systems. Among the many potential attacks that target browsers, vulnerabilities in browser extensions have received
Semanticss-based program analysis requires one to (1) start from a "friendly" semantics; (2) design a "congenial" lattice of runtime properties; (3) associate a "relevant"
Predictive models are fundamental to engineering reliable software systems. However, designing conservative, computable approximations for the behavior of programs remains a difficult and error-prone process for modern high-level
