Nowadays, cybercrimes are grown exponentially which is consistent with the growth of technology. During digital forensic investigations, investigators are facing various kinds of issues while solving the stuff of cybercrime cases. Moreover, the task to solve case stuff has become critical for forensic teams as the volume of data to be examined is huge for the particular cyber investigation project that needs to complete with success.
Therefore, to speed up the examination process and help digital forensic investigators to extract the evidence, investigators can opt for the advanced feature of “Filtering”. It can bring all the factual details of the crime to the surface. For this, digital forensic experts need a powerful forensic application such as MailXaminer Email Examiner Tool which hosts a variety of features to simplify the very complex nature of data elements. It enables to filter of the suspected data in a convenient and risk-free manner.
In digital forensics, filtering can be used to separate out the required data based on filters, so that users can examine suspected data easily without wasting the time in examining whole data. Filters, which are inbuilt within the tool are created on the basis of GREP expressions that can be used to search desired data by matching the data strings. The GREP filter search also enables the investigators to create new filters during the process of investigation. These advanced filters can filter out data items that contain particular GREP expressions or sequences of words.
MailXaminer is an efficient forensic software with a wide variety of amazing features including filtering search. The filtering search feature of the tool provides several filters that are Credit Card Numbers, Dates and Times, Deleted, Domain Name, Email, Evidence Files, Internet patterns, Keywords, Others, Personal Identifiers, Phone Numbers, Saved Searches, Suspected Images, etc. Along with these inbuilt filters, users can create or define any filter for their own searches. Filters also have sub filters wherein users can search the required data accordingly.
To get the deleted files, investigators can use the filter named “Deleted Files”, which can easily filter out the deleted data files. In most cases, some data files may get missed because they have been deleted by the user/cybercriminal, either accidentally or intentionally at the time of crime or post-crime. All the files that were deleted by the criminal are stacked in a folder called “Deleted Files”. As a result, the tool can easily identify them for investigation purposes.
