Adversarial Shadows in Digital Forensics: New Insights Into File Fragment Classification Vulnerabilities and Defenses

IEEE Access
The paper is a comprehensive survey of adversarial attacks on file fragment classification (FFC) models - a relatively unexplored area in digital forensics, given the increasing application of machine learning techniques.

File Fragment Classification-The Case for Specialized Approaches [PDF]

2009 Fourth International IEEE Workshop on Systematic Approaches to Digital Forensic Engineering, 2009
Increasingly advances in file carving, memory analysis and network forensics requires the ability to identify the underlying type of a file given only a file fragment. Work to date on this problem has relied on identification of specific byte sequences in file headers and footers, and the use of statistical analysis and machine learning algorithms ...

Fragments‐Expert: A graphical user interface MATLAB toolbox for classification of file fragments [PDF]

Concurrency and Computation: Practice and Experience, 2020
SummaryThe classification of file fragments of various file formats is an essential task in various applications such as firewalls, intrusion detection systems, antiviruses, web content filtering, and digital forensics. However, the community lacks a suitable software tool that can integrate major methods for feature extraction from file fragments and ...

Approaches to the classification of high entropy file fragments [PDF]

Digital Investigation, 2013
In this paper we propose novel approaches to the problem of classifying high entropy file fragments. We achieve 97% correct classification for encrypted fragments and 78% for compressed. Although classification of file fragments is central to the science of Digital Forensics, high entropy types have been regarded as a problem. Roussev and Garfinkel [1]

Bayesian modeling of recombination events in bacterial populations [PDF]

, 2008
Background: We consider the discovery of recombinant segments jointly with their origins within multilocus DNA sequences from bacteria representing heterogeneous populations of fairly closely related species.

o-glasses: Visualizing X86 Code From Binary Using a 1D-CNN

IEEE Access, 2020
Malicious document files used in targeted attacks often contain a small program called shellcode. It is often hard to prepare a runnable environment for dynamic analysis of these document files because they exploit specific vulnerabilities.

Measuring fragmentation of open space in urbanised Flanders: an evaluation of four methods [PDF]

, 2016
The open space in Flanders, the northern part of Belgium, can hardly be seen as really open. From the Middle Ages onward this area has been known for its spread out development pattern, which has even strengthened in recent decades.

Gerstmann-Sträussler-Scheinker disease revisited: accumulation of covalently-linked multimers of internal prion protein fragments [PDF]

, 2019
Despite their phenotypic heterogeneity, most human prion diseases belong to two broadly defined groups: Creutzfeldt-Jakob disease (CJD) and Gerstmann-Sträussler-Scheinker disease (GSS).
