Harnessing Predictive Models For Assisting Network Forensic Investigations Of Dns Tunnels, Irvin Homem, Panagiotis Papapetrou
Harnessing Predictive Models For Assisting Network Forensic Investigations Of Dns Tunnels, Irvin Homem, Panagiotis Papapetrou
Annual ADFSL Conference on Digital Forensics, Security and Law
In recent times, DNS tunneling techniques have been used for malicious purposes, however network security mechanisms struggle to detect them. Network forensic analysis has been proven effective, but is slow and effort intensive as Network Forensics Analysis Tools struggle to deal with undocumented or new network tunneling techniques. In this paper, we present a machine learning approach, based on feature subsets of network traffic evidence, to aid forensic analysis through automating the inference of protocols carried within DNS tunneling techniques. We explore four network protocols, namely, HTTP, HTTPS, FTP, and POP3. Three features are extracted from the DNS tunneled traffic: …

Does Isis Satisfy The Criteria Of An Apocalyptic Islamic Cult? An Evidence-Based Historical Qualitative Meta-Analysis, Diane Maye Zorri, Bruce Barron
Publications
The U.S. has been battling ISIS and its forerunners for over two decades; however, ISIS continues to endure and expand. While described as a death cult by some political leaders and other key stakeholders, this assertion received little consideration in the scholarly literature. The purpose of this study was to ascertain whether ISIS satisfied the criteria of an apocalyptic Islamic cult through the application of a historical qualitative research design and meta-analysis. Based on the results, the null hypothesis that ISIS does not satisfy the criteria of an apocalyptic Islamic cult was rejected, and the hypothesis that ISIS satisfies the …

Autarky Or Interdependence? U.S. Vs. European Security And Defense Industries In A Globalized Market, Diane Maye Zorri
Publications
Globalization theorists show how downward pressure to compete and/or
save costs in global markets will lead producers and consumers to source
goods and services in the cheapest and most efficient manner. However, in
certain sectors, such as the defense industry, security concerns and politics
can overshadow economic logic when it comes to making procurement
decisions. These political and security concerns keep the U.S. defense
industry from using the most cost-effective supply chains and
manufacturing centers, whereas in Europe, post-Cold War socioeconomic
and political realities allowed for more transnational cooperation on
defense procurement. Three cases serve to illustrate the spectrum between …
Spaceways: Airspace In Outer Space, Scott Haeffelin
Spaceways: Airspace In Outer Space, Scott Haeffelin
Space Traffic Management Conference
Forecasted future demand in space travel is driving the need for the development of space traffic management. Currently, orbital space traffic is mostly unregulated with internationally agreed upon best practices and self-interest driving space operators to avoid collisions with other spacecraft. This paper explores the future of space travel by presenting a concept of creating “airspace in space” or spaceways to manage the ever growing volumes of space traffic. Spaceways are analogous to airspace for aircraft with the goal of increasing levels of safety and reducing probabilities of collision. These goals can be achieved by creating traffic rules, defining valuable …

Assessing The Gap: Measure The Impact Of Phishing On An Organization, Brad Wardman
Annual ADFSL Conference on Digital Forensics, Security and Law
Phishing has become one of the most recognized words associated with cybercrime. As more organizations are being targeted by phishing campaigns, there are more options within the industry to deter such attacks. However, there is little research into how much damage these campaigns are causing organizations. This paper will show how financial organizations can be impacted by phishing and present a method for accurately quantifying resultant monetary losses. The methodology presented in this paper can be adapted to other organizations in order to quantify phishing losses across industries.

Inferring Previously Uninstalled Applications From Residual Partial Artifacts, Jim Jones, Tahir Khan, Kathryn Laskey, Alex Nelson, Mary Laamanen, Douglas White
Annual ADFSL Conference on Digital Forensics, Security and Law
In this paper, we present an approach and experimental results to suggest the past presence of an application after the application has been uninstalled and the system has remained in use. Current techniques rely on the recovery of intact artifacts and traces, e.g., whole files, Windows Registry entries, or log file entries, while our approach requires no intact artifact recovery and leverages trace evidence in the form of residual partial files. In the case of recently uninstalled applications or an instrumented infrastructure, artifacts and traces may be intact and complete. In most cases, however, digital artifacts and traces are al- …
One-Time Pad Encryption Steganography System, Michael J. Pelosi, Gary Kessler, Michael Scott S. Brown
One-Time Pad Encryption Steganography System, Michael J. Pelosi, Gary Kessler, Michael Scott S. Brown
Annual ADFSL Conference on Digital Forensics, Security and Law
In this paper we introduce and describe a novel approach to adaptive image steganography which is combined with One-Time Pad encryption, and demonstrate the software which implements this methodology. Testing using the state-of-the-art steganalysis software tool StegExpose concludes the image hiding is reliably secure and undetectable using reasonably-sized message payloads (≤25% message bits per image pixel; bpp). Payload image file format outputs from the software include PNG, BMP, JP2, JXR, J2K, TIFF, and WEBP. A variety of file output formats is empirically important as most steganalysis programs will only accept PNG, BMP, and possibly JPG, as the file inputs.

Covert6: A Tool To Corroborate The Existence Of Ipv6 Covert Channels, Raymond A. Hansen, Lourdes Gino, Dominic Savio
Annual ADFSL Conference on Digital Forensics, Security and Law
Covert channels are any communication channel that can be exploited to transfer information in a manner that violates the system’s security policy. Research in the field has shown that, like many communication channels, IPv4 and the TCP/IP protocol suite have been susceptible to covert channels, which could be exploited to leak data or be used for anonymous communications. With the introduction of IPv6, researchers are acutely aware that many vulnerabilities of IPv4 have been remediated in IPv6. However, a proof of concept covert channel system was demonstrated in 2006. A decade later, IPv6 and its related protocols have undergone major …

Acceleration Of Statistical Detection Of Zero-Day Malware In The Memory Dump Using Cuda-Enabled Gpu Hardware, Igor Korkin, Iwan Nesterow
Annual ADFSL Conference on Digital Forensics, Security and Law
This paper focuses on the anticipatory enhancement of methods of detecting stealth software. Cyber security detection tools are insufficiently powerful to reveal the most recent cyber-attacks which use malware. In this paper, we will present first an idea of the highest stealth malware, as this is the most complicated scenario for detection because it combines both existing anti-forensic techniques together with their potential improvements. Second, we will present new detection methods which are resilient to this hidden prototype. To help solve this detection challenge, we have analyzed Windows’ memory content using a new method of Shannon Entropy calculation; methods of …
Using Computer Behavior Profiles To Differentiate Between Users In A Digital Investigation, Shruti Gupta, Marcus Rogers
Using Computer Behavior Profiles To Differentiate Between Users In A Digital Investigation, Shruti Gupta, Marcus Rogers
Annual ADFSL Conference on Digital Forensics, Security and Law
Most digital crimes involve finding evidence on the computer and then linking it to a suspect using login information, such as a username and a password. However, login information is often shared or compromised. In such a situation, there needs to be a way to identify the user without relying exclusively on login credentials. This paper introduces the concept that users may show behavioral traits which might provide more information about the user on the computer. This hypothesis was tested by conducting an experiment in which subjects were required to perform common tasks on a computer, over multiple sessions. The …

Child Abuse Material (CAM) is widely available on P2P networks. Over the last decade several tools were made for 24/7 monitoring of peer-to-peer (P2P) networks to discover suspects that use these networks for downloading and distribution of CAM. For some countries the amount of cases generated by these tools is so great that Law Enforcement (LE) just cannot handle them all. This is not only leading to backlogs and prioritizing of cases but also leading to discussions about the possibility of disrupting these networks and sending warning messages to potential CAM offenders. Recently, investigators are reporting that they are creating …

The risk of fatigue on pilot performance and safety is well recognized in aviation. In response to increased safety concerns, the Federal Aviation Administration addressed fatigue risk for passenger airline pilots in Title 14 Code of Federal Regulations Part 117, which included accommodations to address fatigue related risk-factors such as circadian rhythm and the phenomenon commonly described as jet-lag. The rule became effective in January 2014. A survey was conducted in March and April of 2014 to better understand pilot perceptions of the new Part 117 rule. This study analyzed survey responses from 92 self-identified pilots to determine the effect …
