In this paper, we give an overview of the BitBlaze project, a new approach to computer security via binary analysis. In particular, BitBlaze focuses on building a unified binary analysis platform and using it to provide novel solutions to a broad spectrum of different security problems. The binary analysis platform is designed to enable accurate analysis,(More)
Malicious programs spy on users' behavior and compromise their privacy. Even software from reputable vendors, such as Google Desktop and Sony DRM media player, may perform undesirable actions. Unfortunately, existing techniques for detecting malware and analyzing unknown code samples are insufficient and have significant shortcomings. We observe that(More)
The increasing popularity of Android apps makes them the target of malware authors. To defend against this severe increase of Android malwares and help users make a better evaluation of apps at install time, several approaches have been proposed. However, most of these solutions suffer from some shortcomings; computationally expensive, not general or not(More)
The prevalence of mobile platforms, the large market share of Android, plus the openness of the Android Market makes it a hot target for malware attacks. Once a malware sample has been identified, it is critical to quickly reveal its malicious intent and inner workings. In this paper we present DroidScope, an Android analysis platform that continues the(More)
As reverse engineering becomes a prevalent technique to analyze malware, malware writers leverage various anti-reverse engineering techniques to hide their code. One technique commonly used is code packing as packed executables hinder code analysis. While this problem has been previously researched, the existing solutions are either unable to handle novel(More)
Protocol reverse engineering, the process of extracting the application-level protocol used by an implementation, without access to the protocol specification, is important for many network security applications. Recent work [17] has proposed protocol reverse engineering by using clustering on network traces. That kind of approach is limited by the lack of(More)
Spyware is a class of malicious code that is surreptitiously installed on victims’ machines. Once active, it silently monitors the behavior of users, records their web surfing habits, and steals their passwords. Current anti-spyware tools operate in a way similar to traditional virus scanners. That is, they check unknown programs against signatures(More)
The drastic increase of Android malware has led to a strong interest in developing methods to automate the malware analysis process. Existing automated Android malware detection and classification methods fall into two general categories: 1) signature-based and 2) machine learning-based. Signature-based approaches can be easily evaded by bytecode-level(More)
WebView is an essential component in both Android and iOS platforms, enabling smartphone and tablet apps to embed a simple but powerful browser inside them. To achieve a better interaction between apps and their embedded "browsers", WebView provides a number of APIs, allowing code in apps to invoke and be invoked by the JavaScript code within the web pages,(More)
Installing various hooks into the victim system is an important attacking strategy employed by malware, including spyware, rootkits, stealth backdoors, and others. In order to defeat existing hook detectors, malware writers keep exploring new hooking mechanisms. However, the current malware analysis procedure is painstaking, mostly manual and error-prone.(More)
