Design and implementation of robust systems for secure malware detection

Malicious software (malware) have significantly increased in terms of number and effectiveness during the past years. Until 2006, such software were mostly used to disrupt network infrastructures or to show coders’ skills. Nowadays, malware constitute a very important source of economical profit, and are very difficult to detect. Thousands of novel variants are released every day, and modern obfuscation techniques are used to ensure that signature-based anti-malware systems are not able to detect such threats. This tendency has also appeared on mobile devices, with Android being the most targeted platform. To counteract this phenomenon, a lot of approaches have been developed by the scientific community that attempt to increase the resilience of anti-malware systems. Most of these approaches rely on machine learning, and have become very popular also in commercial applications. However, attackers are now knowledgeable about these systems, and have started preparing their countermeasures. This has lead to an arms race between attackers and developers. Novel systems are progressively built to tackle the attacks that get more and more sophisticated. For this reason, a necessity grows for the developers to anticipate the attackers’ moves. This means that defense systems should be built proactively, i.e., by introducing some security design principles in their development. The main goal of this work is showing that such proactive approach can be employed on a number of case studies. To do so, I adopted a global methodology that can be divided in two steps. First, understanding what are the vulnerabilities of current state-of-the-art systems (this anticipates the attacker’s moves). Then, developing novel systems that are robust to these attacks, or suggesting research guidelines with which current systems can be improved. This work presents two main case studies, concerning the detection of PDF and Android malware. The idea is showing that a proactive approach can be applied both on the X86 and mobile world. The contributions provided on this two case studies are multifolded. With respect to PDF files, I first develop novel attacks that can empirically and optimally evade current state-of-the-art detectors. Then, I propose possible solutions with which it is possible to increase the robustness of such detectors against known and novel attacks. With respect to the Android case study, I first show how current signature-based tools and academically developed systems are weak against empirical obfuscation attacks, which can be easily employed without particular knowledge of the targeted systems. Then, I examine a possible strategy to build a machine learning detector that is robust against both empirical obfuscation and optimal attacks. Finally, I will show how proactive approaches can be also employed to develop systems that are not aimed at detecting malware, such as mobile fingerprinting systems. In particular, I propose a methodology to build a powerful mobile fingerprinting system, and examine possible attacks with which users might be able to evade it, thus preserving their privacy. To provide the aforementioned contributions, I co-developed (with the cooperation of the researchers at PRALab and Ruhr-Universität Bochum) various systems: a library to perform optimal attacks against machine learning systems (AdversariaLib), a framework for automatically obfuscating Android applications, a system to the robust detection of Javascript malware inside PDF files (LuxOR), a robust machine learning system to the detection of Android malware, and a system to fingerprint mobile devices. I also contributed to develop Android PRAGuard, a dataset containing a lot of empirical obfuscation attacks against the Android platform. Finally, I entirely developed Slayer NEO, an evolution of a previous system to the detection of PDF malware. The results attained by using the aforementioned tools show that it is possible to proactively build systems that predict possible evasion attacks. This suggests that a proactive approach is crucial to build systems that provide concrete security against general and evasion attacks

A Model-driven Approach for the Automatic Generation of System-Level Test Cases

Systems at the basis of the modern society, as the as the homeland security, the environment protection, the public and private transportations, the healthcare or the energy supply depend on the correct functioning of one or more embedded systems. In several cases, such systems shall be considered critical, since the consequences of their failures may result in economic losses, damages to the environment or even injuries to human life. Possible disastrous consequences of embedded critical systems, suggest that discover flaws during systems development and avoid their propagation to the system execution, is a crucial task. In fact, most of the failures found during the usage of embedded critical systems, is due to errors introduced during early stages of the system development. Thus, it is desiderable to start Verification and Validation (V&V) activities during early stages of a system life cycle. However such V&V activities can account over the 50% of times and costs of a system life cycle and there is therefore the need to introduce techniques able to reduce the accounted resources without losses in term efficiency. Among the methodologies found in scientific and industrial literature there is a large interest in the V&V automation. In particular, automatic verification can be performed during different stages of a system development life cycle and can assume different meanings. In this thesis, the focus is on the automation of the test cases generation phase performed at the System level starting from SUT and test specifications. A recent research trend, related to this, is to support such process providing a flexible tool chain allowing for effective Model Driven Engineering (MDE) approaches. The adoption of a model-driven techniques requires the modelling of the SUT to drive the generation process, by using suitable domain-specific modelling languages and model transformations. Thus, a successful application of the MDE principles is related to the choice of the high-level language for SUT specification and the tools and techniques provided to support the V\&V processes. According to this, the model-driven approach define in this thesis relies on three key factors: (1) the definition of new domain-specific modelling languages (DSMLs) for the SUT and the test specifications, (2) the adoption of model checking techniques to realize the generation of the test cases and (3) the implementation of a concrete framework providing a complete tool chain supporting the automation process. This work is partially involved in an ARTEMIS European project CRYSTAL (CRitical sYSTem engineering AcceLeration). CRYSTAL is strongly industry-oriented and aims at achieving technical innovation by a user-driven approach based on the idea to apply engineering methods to industrially relevant Use Cases from the automotive, aerospace, rail and health-care sectors. The DSML that will be presented in this thesis, emerged as an attempt to address the modelling requirements and the design practices of the industrial partners of the project, within a rigorous and well-founded formal specification and verification approach. In fact, the main requirement that a modelling language suitable for the industry should have is to be small and as simple as possible. Thus, the modelling language should provide an adequate set of primitive constructs to allow for a natural modelling of the system of interest. Furthermore, the larger the gap between the design specification and the actual implementation is, the less useful the results of the design analysis would be. The test case generation is supported by model checking techniques; the SUT and test models are in fact translated in specifications expressed by the language adopted by a model checker. The thesis discusses all the issues addressed in the mapping process and provides their implementations by means of model transformations. A class of test specifications is addressed to exemplify the generation process over a common class of reachability requirements. The model-driven approach discussed in the thesis is applied in the contest of the railway control systems, and in particular on some of the key functionalities of the Radio Block Center, the main component of the ERTMS/ETCS standards for the interoperability of the railway control systems in the European Community. The thesis is organized as follows. The first chapter introduces embedded critical systems and outlines the main research trends related to their V&V process. The Chapter 2 outlines the state of the art in testing automation with a particular focus on model-driven approaches for automatic test generation. The same Chapter 2 provides also the necessary technical background supporting to understand the development process of the supporting framework. The Chapter 3 describes the context of the CRYSTAL project and the proposed model-driven approach partially involved in its activities. The Chapter 4 describes the domains pecific modelling languages defined for the modelling of the SUT specifications and of the test generation outcomes. Moreover the guidelines defined for modelling test specifications are discussed. The Chapter 5 focuses on the mapping process that enable the translation of the high-level language for the modelling of the SUT specification to the language adopted by the chosen model checker. The implementation of the overall framework is addressed in Chapter 6. Here model transformations realizing the defined mappings and the architecture of the Test Case Generator (TCG) framework are described and discussed. The Chapter 7 shows the results of the application of the approach in the context of the railway control systems and in particular to the Radio Block Centre system, a key component in the ERTMS/ETCS standard. Chapter 8 end the thesis, giving some conclusive remarks
