BitTorrent Sync: First Impressions and Digital Forensic Implications
With professional and home Internet users becoming increasingly concerned
with data protection and privacy, the privacy afforded by popular cloud file
synchronisation services, such as Dropbox, OneDrive and Google Drive, is coming
under scrutiny in the press. A number of these services have recently been
reported as sharing information with governmental security agencies without
warrants. BitTorrent Sync is seen as an alternative by many and has gathered
over two million users by December 2013 (doubling since the previous month).
The service is completely decentralised, offers much of the same
synchronisation functionality of cloud powered services and utilises encryption
for data transmission (and optionally for remote storage). The importance of
understanding BitTorrent Sync and its resulting digital investigative
implications for law enforcement and forensic investigators will be paramount
to future investigations. This paper outlines the client application, its
detected network traffic and identifies artefacts that may be of value as
evidence for future digital investigations.Comment: Proc. of Digtial Forensics Research Workshop (DFRWS EU 2014
BitTorrent Sync: Network Investigation Methodology
The volume of personal information and data most Internet users find
themselves amassing is ever increasing and the fast pace of the modern world
results in most requiring instant access to their files. Millions of these
users turn to cloud based file synchronisation services, such as Dropbox,
Microsoft Skydrive, Apple iCloud and Google Drive, to enable "always-on" access
to their most up-to-date data from any computer or mobile device with an
Internet connection. The prevalence of recent articles covering various
invasion of privacy issues and data protection breaches in the media has caused
many to review their online security practices with their personal information.
To provide an alternative to cloud based file backup and synchronisation,
BitTorrent Inc. released an alternative cloudless file backup and
synchronisation service, named BitTorrent Sync to alpha testers in April 2013.
BitTorrent Sync's popularity rose dramatically throughout 2013, reaching over
two million active users by the end of the year. This paper outlines a number
of scenarios where the network investigation of the service may prove
invaluable as part of a digital forensic investigation. An investigation
methodology is proposed outlining the required steps involved in retrieving
digital evidence from the network and the results from a proof of concept
investigation are presented.Comment: 9th International Conference on Availability, Reliability and

A Framework for Genetic Algorithms Based on Hadoop
Genetic Algorithms (GAs) are powerful metaheuristic techniques mostly used in
many real-world applications. The sequential execution of GAs requires
considerable computational power both in time and resources. Nevertheless, GAs
are naturally parallel and accessing a parallel platform such as Cloud is easy
and cheap. Apache Hadoop is one of the common services that can be used for
parallel applications. However, using Hadoop to develop a parallel version of
GAs is not simple without facing its inner workings. Even though some
sequential frameworks for GAs already exist, there is no framework supporting
the development of GA applications that can be executed in parallel. In this
paper is described a framework for parallel GAs on the Hadoop platform,
following the paradigm of MapReduce. The main purpose of this framework is to
allow the user to focus on the aspects of GA that are specific to the problem
to be addressed, being sure that this task is going to be correctly executed on
the Cloud with a good performance. The framework has been also exploited to
develop an application for Feature Subset Selection problem. A preliminary
analysis of the performance of the developed GA application has been performed
using three datasets and shown very promising performance
