Malware stands for malicious software. It is software that is designed with a harmful intent. A malware detector is a system that attempts to identify malware using Application Programming Interface (API) call graph technique and/or other techniques. API call graph techniques follow two main steps, namely, transformation of malware samples into an API call graph using API call graph constructio...

An application programming interface (API) is a specification intended to be used as an interface by software components to communicate with each other. An API may include specifications for routines, data structures, object classes, and variables. An API specification can take many forms, including an International Standard such as POSIX or vendor documentation such as the Microsoft Windows AP...

A common way to get insight into a malicious program’s functionality is to look at which API functions it calls. To complicate the reverse engineering of their programs, malware authors deploy API obfuscation techniques, hiding them from analysts’ eyes and anti-malware scanners. This problem can be partially addressed by using dynamic analysis; that is, by executing a malware sample in a contro...

Software developers often encapsulate reusable code as Application Programming Interfaces (APIs). The co-evolution of applications and APIs may motivate an API migration: the replacement of application dependencies to an original API by dependencies to an alternative API that provides similar functionality and abstractions. In this dissertation, we investigate issues associated with API migrati...

Electronic Health Records (EHR) offer patients the opportunity to access their own medical records. Google and Microsoft recently extended their public services by introducing internet-based personal healthcare information platforms – Google Health and Microsoft HealthVault. Over one hundred thousand people have registered at the two services since they were launched. Both companies invite othe...
