Image Similarity Using Dynamic Time Warping Of Fractal Features, Ahmed Ibrahim, Craig Valli
Australian Digital Forensics Conference
Hashing algorithms such as MD/SHA variants have been used for years by forensic investigators to look for known artefacts of interest such as malicious files. However, such hashing algorithms are not effective when their hashes change with the slightest alteration in the file. Fuzzy hashing overcame this limitation to a certain extent by providing a close enough measure for slight modifications. As such, image forensics is an essential part of any digital crime investigation, especially in cases involving child pornography. Unfortunately such hashing algorithms can be thwarted easily by operations as simple as saving the original file in a different …

Analysis Into Developing Accurate And Efficient Intrusion Detection Approaches, Priya Rabadia, Craig Valli
Australian Digital Forensics Conference
Cyber-security has become more prevalent as more organisations are relying on cyber-enabled infrastructures to conduct their daily actives. Subsequently cybercrime and cyber-attacks are increasing. An Intrusion Detection System (IDS) is a cyber-security tool that is used to mitigate cyber-attacks. An IDS is a system deployed to monitor network traffic and trigger an alert when unauthorised activity has been detected. It is important for IDSs to accurately identify cyber-attacks against assets on cyber-enabled infrastructures, while also being efficient at processing current and predicted network traffic flows. The purpose of the paper is to outline the importance of developing an accurate and …
Suitability Of Lacunarity Measure For Blind Steganalysis, Ahmed Ibrahim
Suitability Of Lacunarity Measure For Blind Steganalysis, Ahmed Ibrahim
Australian Digital Forensics Conference
Blind steganalysis performance is influenced by several factors including the features used for classification. This paper investigates the suitability of using lacunarity measure as a potential feature vectorfor blind steganalysis. Differential Box Counting (DBC) based lacunarity measure has been employed using the traditional sequential grid (SG) and a new radial strip (RS) approach. The performance of the multi-class SVM based classifier was unfortunately not what was expected. However, the findings show that both the SG and RS lacunarity produce enough discriminating features that warrant further research.
Finding Evidence Of Wordlists Being Deployed Against Ssh Honeypots – Implications And Impacts, Priya Rabadia, Craig Valli
Finding Evidence Of Wordlists Being Deployed Against Ssh Honeypots – Implications And Impacts, Priya Rabadia, Craig Valli
Australian Digital Forensics Conference
This paper is an investigation focusing on activities detected by three SSH honeypots that utilise Kippo honeypot software. The honeypots were located on the same /24 IPv4 network and configured as identically as possible. The honeypots used the same base software and hardware configurations. The data from the honeypots were collected during the period 17th July 2012 and 26th November 2013, a total of 497 active day periods. The analysis in this paper focuses on the techniques used to attempt to gain access to these systems by attacking entities. Although all three honeypots are have the same configuration settings and …
An Overview And Examination Of Digital Pda Devices Under Forensics Toolkits, Krishnun Sansurooah
An Overview And Examination Of Digital Pda Devices Under Forensics Toolkits, Krishnun Sansurooah
Australian Digital Forensics Conference
Personal Digital Assistants most commonly known as PDAs are becoming more and more fashionable and affordable in the working environment. With the advent and rapidly increasing technology these handled devices are now targeted by a lot of person with criminal intentions. But unfortunately crime does not choose its technology and nowadays those ultra light handhelds are getting more and more involved in crimes. This therefore become an onerous task for the forensics examiners who needs the proper forensics tools to investigate the information held on these devices. The purpose of this report will browse the current forensics toolkits available and …
An Approach In Identifying And Tracing Back Spoofed Ip Packets To Their Sources, Krishnun Sansurooah
An Approach In Identifying And Tracing Back Spoofed Ip Packets To Their Sources, Krishnun Sansurooah
Australian Digital Forensics Conference
With internet expanding in every aspect of businesses infrastructure, it becomes more and more important to make these businesses infrastructures safe and secure to the numerous attacks perpetrated on them conspicuously when it comes to denial of service (DoS) attacks. A Dos attack can be summarized as an effort carried out by either a person or a group of individual to suppress a particular outline service. This can hence be achieved by using and manipulating packets which are sent out using the IP protocol included into the IP address of the sending party. However, one of the major drawbacks is …
The Effectiveness Of Investigative Tools For Secure Digital (Sd) Memory Card Forensics, Haitham Al-Hajri, Patricia Williams
The Effectiveness Of Investigative Tools For Secure Digital (Sd) Memory Card Forensics, Haitham Al-Hajri, Patricia Williams
Australian Digital Forensics Conference
There are many freeware based tools that can be downloaded from the World Wide Web. This paper reports the retrieval results of using these tools on digital images which have been deleted from Secure Digital (SD) cards. Since SD cards and USB flash drives are considered solid state technology, the tools selected are specifically for solid state drives. This research helps classify the selection of the most effective freeware tools that could be used to recover lost or deleted images. Further, it includes some of the issues that would face forensic examiners undertaking such investigations. The tools were tested using …
