    Analysis avoidance techniques of malicious software

    Anti Virus (AV) software generally employs signature matching and heuristics to detect the presence of malicious software (malware). The generation of signatures and determination of heuristics is dependent upon an AV analyst having successfully determined the nature of the malware, not only for recognition purposes, but also for the determination of infected files and startup mechanisms that need to be removed as part of the disinfection process. If a specimen of malware has not been previously extensively analyzed, it is unlikely to be detected by AV software. In addition, malware is becoming increasingly profit driven and more likely to incorporate stealth and deception techniques to avoid detection and analysis to remain on infected systems for a myriad of nefarious purposes. Malware extends beyond the commonly thought of virus or worm, to customized malware that has been developed for specific and targeted miscreant purposes. Such customized malware is highly unlikely to be detected by AV software because it will not have been previously analyzed and a signature will not exist. Analysis in such a case will have to be conducted by a digital forensics analyst to determine the functionality of the malware. Malware can employ a plethora of techniques to hinder the analysis process conducted by AV and digital forensics analysts. The purpose of this research has been to answer three research questions directly related to the employment of these techniques as: 1. What techniques can malware use to avoid being analyzed? 2. How can the use of these techniques be detected? 3. How can the use of these techniques be mitigated

    Command & Control: Understanding, Denying and Detecting - A review of malware C2 techniques, detection and defences

    Full text link
    In this survey, we first briefly review the current state of cyber attacks, highlighting significant recent changes in how and why such attacks are performed. We then investigate the mechanics of malware command and control (C2) establishment: we provide a comprehensive review of the techniques used by attackers to set up such a channel and to hide its presence from the attacked parties and the security tools they use. We then switch to the defensive side of the problem, and review approaches that have been proposed for the detection and disruption of C2 channels. We also map such techniques to widely-adopted security controls, emphasizing gaps or limitations (and success stories) in current best practices.Comment: Work commissioned by CPNI, available at c2report.org. 38 pages.

    An Assessment of North Korean Threats and Vulnerabilities in Cyberspace

    This thesis answers the fundamental questions of what North Korean capabilities and intent in cyberspace are and what North Korean threats and vulnerabilities are associated with these. It argues that although North Korea’s cyberspace resources and capabilities have increased and reached a level that represents an advanced persistent threat, its cyberspace operations have remained restrained and regional. It also argues that North Korea’s valuable assets include its ability to control cyberspace within North Korea and its ability to engage in cyberspace activities and operations from abroad. The thesis recommends that the United States government exploit these assets by denying and disrupting the use of cyberspace by covert cyber units outside of North Korea, as well as by enabling and ensuring the less monitored and less controlled use of cyberspace by civilians inside of North Korea

    So You Think Your Router Is Safe?

    A home router is a common item found in today’s household and is seen by most as just an Internet connection enabler. Users don’t realize how important this single device is in terms of privacy protection. The router is the centerpiece through which all the household Internet activities including ecommerce, tax filing and banking pass through. When this central device is compromised, users are at risk of having personal and confidential data exposed. Over the past decade, information security professionals have been shedding light on vulnerabilities plaguing consumer routers. Yet, most users are unaware of all the different ways a router can be compromised and tend to focus only on setting up a strong password to stop the neighbor from piggy backing on the Internet

    Deregulation Using Stealth “Science” Strategies

    Get PDF
    In this Article, we explore the “stealth” use of science by the Executive Branch to advance deregulation and highlight the limited, existing legal and institutional constraints in place to discipline and discourage these practices. Political appointees have employed dozens of strategies over the years, in both Democratic and Republican administrations, to manipulate science in ends-oriented ways that advance the goal of deregulation. Despite this bald manipulation of science, however, the officials frequently present these strategies as necessary to bring “sound science” to bear on regulatory decisions. To begin to address this problem, it is important to reconceptualize how the administrative state addresses science-intensive decisions. Rather than allow agencies and the White House to operate as a cohesive unit, institutional bounds should be drawn around the scientific expertise lodged within the agencies. We propose that the background scientific work prepared by agency staff should be firewalled from the evaluative, policymaking input of the remaining officials, including politically appointed officials, in the agency
