Malware clustering and classification are important tools that enable analysts to prioritize their malware analysis efforts. The recent emergence of fully automated methods for malware clustering and classification that report high accuracy suggests that this problem may largely be solved. In this paper, we report the results of our attempt to confirm our conjecture that the method of selecting ground-truth data in prior evaluations biases their results toward high accuracy. To examine this conjecture, we apply clustering algorithms from a different domain (plagiarism detection), first to the dataset used in a prior work's evaluation and then to a wholly new …

Users of text search engines are increasingly wary that their activities may disclose confidential information about their business or personal profiles. It would be desirable for a search engine to perform document retrieval for users while protecting their intent. In this paper, we identify the privacy risks arising from semantically related search terms within a query, and from recurring highspecificity query terms in a search session. To counter the risks, we propose a solution for a similarity text retrieval system to offer anonymity and plausible deniability for the query terms, and hence the user intent, without degrading the system’s precision-recall …

Unauthorized tracking of RFID tagged assets at the system level, where an adversary tracks movement of RFID tagged assets by eavesdropping network messages or compromising date center servers, has not been well recognized in prior research. Compared to the traditional unauthorized tracking by clandestine scanning at the physical level, unauthorized tracking at the system level could be even more harmful as the adversary is able to obtain tracking information on a global scale and without physical presence. This paper analyzes the threat of unauthorized tracking by a semi-trusted RFID Discovery Service which maintains a database of RFID tag location records …

Malware Detection Based On Structural And Behavioural Features Of Api Calls, Manoun Alazab, Robert Layton, Sitalakshmi Venkataraman, Paul Watters
International Cyber Resilience conference
In this paper, we propose a five-step approach to detect obfuscated malware by investigating the structural and behavioural features of API calls. We have developed a fully automated system to disassemble and extract API call features effectively from executables. Using n-gram statistical analysis of binary content, we are able to classify if an executable file is malicious or benign. Our experimental results with a dataset of 242 malwares and 72 benign files have shown a promising accuracy of 96.5% for the unigram model. We also provide a preliminary analysis by our approach using support vector machine (SVM) and by varying …

Mitigating Cyber-Threats Through Public-Private Partnerships: Low Cost Governance With High-Impact Returns , David M. Cook
International Cyber Resilience conference
The realization that cyber threats can cause the same devastation to a country as physical security risks has taken the long route towards acceptance. Governments and businesses have thrown the glove of responsibility back and forth on numerous occasions, with government agencies citing the need for private enterprise to take up the mantle, and Business returning the gesture by proposing a ‘national’ perspective on cyber security. Ambit claims such as these drain a range of security resources when both sides should work in concert by directing all available energy towards resolving cyber-threats. This paper compares the public-private arrangements through Australasia …

The security of information that is processed and stored in Information and Communications Technology systems is an ongoing problem that, as yet, has not been satisfactorily resolved. Software developers, system architects and managers all aspire to use technology to provide improvements in the protection of information that is processed and stored on these systems. However, they are working in an environment where the threats to the information, the technologies in use and the uses to which the technologies are being employed are changing at a pace which is faster than can be effectively addressed. This paper looks at the underlying …

Small Business - A Cyber Resilience Vulnerability , Patricia A H Williams, Rachel J. Manheke
International Cyber Resilience conference
Small business in Australia comprise 95% of businesses. As a group this means that they contain increasing volumes of personal and business data. This creates escalating vulnerabilities as information is aggregated by various agencies. These vulnerabilities include identity theft and fraud. The threat environment of small business is extensive with both technical and human vulnerabilities. The problem is that the small business environment is being encouraged to adopt e-commerce by the government yet lacks resources in securing its cyber activity. This paper analysed the threats to this situation and found that questions of responsibility by individual businesses and the government …

What Are You Looking For: Identification Of Remnant Communication Artefacts In Physical Memory, Matthew Simon, Jill Slay
International Cyber Resilience conference
Law enforcement has sound methods for investigating and obtaining data about targets that are using traditional communication services such as the Public Switched Telephone Network. The Internet as a data transfer medium is a vastly different paradigm to that of traditional telephony networks. Information about targets using Internet communication technologies cannot be obtained using the same methods used for traditional communication. There has been an identified need for methods to obtain information on targets that have been using Internet communication methods. The acquisition and analysis of physical memory has been proposed as a vector for the recovery of such information. …

Remote access is the means of acquiring access to a computer or network remotely or from distance. It is typically achieved through the internet which connects people, corporate offices and telecommuters to the internal network of organizations or individuals. In recent years there has been a greater adoption of remote desktop applications that help administrators to configure and repair computers remotely over the network. However, this technology has also benefited cyber criminals. For example they can connect to computers remotely and perform illegal activity over the network. This research will focus on Windows mobile phones and the Paraben forensics software …

Which Organisational Model Meets Best Practice Criterion For Critical Infrastructure Providers: An Examination Of The Australian Perspective Based On Case Studies, Andrew Woodward, Craig Valli
International Cyber Resilience conference
While it is recognised that there must be segregation between corporate and process control networks in order to achieve a higher level of security, there is evidence that this is not occurring. Computer and network vulnerability assessments were carried out on three Australian critical infrastructure providers to determine their level of security. The security measures implemented by each organisation have been mapped against best practice recommendations for achieving segregation between process control and corporate networks. One of the organisations used a model which provided a dedicated information security team for provision of security for the process control networks. One of …

Is Cyber Resilience In Medical Practice Security Achievable? , Patricia A H Williams
International Cyber Resilience conference
Australia is moving to a national e-health system with a high level of interconnectedness. The scenario for recovery of such a system, particularly once it is heavily relied upon, may be complex. Primary care medical practices are a fundamental part of the new e-health environment yet function as separate business entities within Australia’s healthcare system. Individually this means that recovery would be reliant on the self-sufficiency of each medical practice. However, the ability of these practices to individually and collectively recover is questionable. The current status of information security in primary care medical practices is compared to the needs of …

As the telegram was replaced by telephony, so to Voice over IP (VoIP) systems are replacing conventional switched wire telephone devices, these systems rely on Internet connectivity for the transmission of voice conversations. This paper is an outline of ongoing preliminary research into malfeasant VoIP activity on the Internet. 30 years ago PABX systems were compromised by hackers wanting to make long distance calls at some other entities expense. This activity faded as telephony became cheaper and PABX systems had countermeasures installed to overcome attacks. Now the world has moved onto the provision of telephony via broadband enabled Voice over …

Theses and Dissertations
Many of the largest technology companies are heavily investing in Cloud Computing technology, making this a major force in the realm of software development. However, this software paradigm brings with it significant data related security issues. This paper discusses some of these security issues and presents a solution. The solution calls for storing data outside of the cloud, and under the control of the cloud consumer. In addition, the solution provides the ability to manipulate data using only the standard HTTP ports that are typically opened at most locations. This solution is implemented using Microsoft's Windows Azure Cloud Computing operating …

A New Hardware-Assisted Pir With O(N) Shuffle Cost, Xuhua Ding, Yanjiang Yang, Robert H. Deng, Shuhong Wang
Research Collection School Of Computing and Information Systems
Since the concept of private information retrieval (PIR) was first formalized by Chor et al., various constructions have been proposed with a common goal of reducing communication complexity. Unfortunately, none of them is suitable for practical settings mainly due to the prohibitively high cost for either communications or computations. The booming of the Internet and its applications, especially, the recent trend in outsourcing databases, fuels the research on practical PIR schemes. In this paper, we propose a hardware-assisted PIR scheme with a novel shuffle algorithm. Our PIR construction entails O(n) offline computation cost, and constant online operations and O(log n) …

Research Collection School Of Computing and Information Systems
In Information Processing Letters (2006), Tan pointed out that the anonymous signcryption scheme proposed by Yang, Wong and Deng (YWD) in ISC 2005 provides neither confidentiality nor anonymity. However, no discussion has been made on how a secure scheme can be made and there is no secure scheme available to date. In this paper, we propose a modification of YWD scheme which resolves the security issues of the original scheme without sacrificing its high efficiency and simple design. Indeed, we show that our scheme achieves confidentiality, existential unforgeability and anonymity with more precise reduction bounds. We also give a variation …

We address the cryptographic topic of proxy re-encryption (PRE), which is a special public-key cryptosystem. A PRE scheme allows a special entity, known as the proxy, to transform a message encrypted with the public key of a delegator (say Alice), into a new ciphertext that is protected under the public key of a delegatee (say Bob), and thus the same message can then be recovered with Bob’s private key. In this paper, in the identity-based setting, we first investigate the relationship between so called mediated encryption and unidirectional PRE. We provide a general framework which converts any secure identity-based unidirectional …
