Droplets and Puddles

That we have the freedom to instantly and intuitively interact with our data whenever we desire is something that we are starting to take for granted. Michelle Govan explains how to exchange data between devices using the Hydrological Cycle.


Programming the Wetware

Continuing on from the first part of his article Keith Scott suggests how certain aspects of human psychology and behaviour may offer ways to influence a user’s actions in the information realm.


Recovering Passwords from Memory

This article continues the work published in Issue 19 of the Digital Forensics Magazine but this time we focus more on analysis methods. Memory dump files contain a real representation of the machine-state at the time of the memory dump; they can be used to recover user-related data such as usernames, passwords and encryption key-files relying on virtual addresses and/or content analysis. Haider M. al-Khateeb examines and demonstrates the methods available to extract such data from a variety of end-user services running on Windows or accessible online via web browsers.


Mac Memory Forensics

There are a number of tools available to analyse OS X, e.g. Volatility, Volafox, Memoryze for Mac, Mac Memory Reader, MacLockPick and Rekall, however the ability to analyse Mac memory will be complex and disconcerting to the novice. In this article Kelvin Wong demonstrates a fast track method of Mac memory forensic analysis by studying the evidence of a very popular Chinese social networking application ‘WeChat’.


Investigating Steganography in Audio Streams

If criminals are technology-minded and apply audio steganography to protect content, it is difficult for forensic investigators to extract the evidence with support from current digital tools. Brian Cusack and James Lu Yao explain why tool selection is crucial to detecting hidden information in audio streams.


Cyber Security Attributes for Critical Infrastructure Systems

In this article Huge Boyes examines the nature of cyber–physical systems and how they differ from the information processing systems used in administrative or banking functions. It discusses the limitations of the traditional information assurance ‘CIA’ triad when applied to these complex systems and illustrates how, with minor modifications, an alternative assurance model can be used to address both cyber security and systems safety.
