Computer antiforensic techniques are a new field in the computer security domain that is expected to grasp more attention in the near future. We also talked about new trends to attack computer forensics tools in order to render their work useless, more difficult, time-consuming, and even debatable in a court of law.
#CHANGE FILE TIME STAMP PORTABLE#
In conclusion, we talk about best practices to reduce our digital footprints by using USB devices, CD/DVDs, and virtual machines in addition to portable applications.

Windows ® usually stores a considerable amount of data as a part of its regular work and such logs can reveal a great amount of detail about previous user actions on a machine. In the next section, we talk about Windows ® antiforensics here we list many techniques and tips to harden your Windows ® installation in order to reduce the amount of digital data created by Windows ® automatically as a part of its normal functions. We also cover how we can eliminate metadata from digital files in addition to changing digital file timestamp attributes to mislead computer forensic tools and investigators. Next, we talk about data destruction techniques, listing three ways in which digital data can be destroyed. It defines its goals and gives the advice to eliminate your traces when using steganographic tools to conceal secret data. It begins by describing the concept of the antiforensic domain in relation to data concealment techniques employed during this book. This chapter is the reverse of Chapter 6. Nihad Ahmad Hassan, Rami Hijazi, in Data Hiding Techniques in Windows OS, 2017 Abstract Besides the questioned image material, PRNU for forensic identification also needs the camera in question for generation of reference data or existing reference data originating from that camera.

PRNU is believed to cause unique fingerprints of imaging sensors ( Alles et al., 2008 Chen et al., 2007). PRNU is primarily caused by varying sensitivity of individual pixels to light due to inhomogeneity and impurities in silicon wafers and imperfections introduced by the sensor manufacturing process. PRNU is a relatively weak pattern of pixel-to-pixel sensitivity differences in digital image sensors. This does not preclude other reasons for an unusual timestamp, however, and should not be accepted in isolation without other testing being undertaken. Using the information in this research, it gives an answer as to how an unusual value can be associated with a file.

For example, if analysis is conducted and a file has a created time of, this would appear to be unusual, especially if it is a Microsoft Word 2010 document, as this version of the software was not available in 1980. This information is important to a practitioner as it may explain unknown file timestamps. These different terminologies are important to understand when examining files. This was further verified with FTK Imager 3.1.0, which displayed the Record Date in the Properties tab (the nomenclature observed for file dates and times for the various forensic programs are listed in Table 7.3). This showed the “Record Change Date” had the same data as the Encase “Entry Modified” information. In a further effort to understand the differing terminology used across the various forensic software programs, we then used Red Wolf Computer Forensics MFT Parser to examine the MFT records from the VMs. įTK 1.81.6 and X-Ways 16.5 did not display an “Entry Modified” time as is listed in Encase.“Last Written” was equal to “Modified” and “Mod Date”

“File Created” was equal to “Created” and “Cr Date” “Last Accessed” was equal to “Accessed” and “Acc Date”
