After examining Tom Warner’s workstation, Team 3 forensic team found 7 emails and 6 files that appear to be non-work related. Starting with the emails, there are multiple occurrences of personal conversation between Tom Warner’s email account and Leslie Stowle’s email account. These conversations included discussions about going to lunch, job promotions, and vacation plans. In the emails referring to the job promotion, Toms email states that he “deserves it and can use the extra money”, and an invitation to lunch is placed towards Leslie Stowle account. Leslie sends an email response to Tom’s e-mail and congratulates him on his promotion. An e-mail from Tom’s account to Leslie’s account then shows that Tom had found a memo from Ms. Price claiming that he was not going to get promoted. Tom’s email then states that he will “get even” and that he was traveling back to his residence after the e-mail was sent. Leslie’s email response tells Tom that he can’t be sure about the accuracy of the claim and asks him to lunch to discuss the matter further. Tom sends an email reply, and says he is sure that he will not get promoted because he saw the memo and has proof now. His email talks about how long he had been employed with the company stating he worked there for seven years and helped start the company, and mentions “they owe me so much.” He then sends an email and declines the lunch invitation due to an upcoming meeting but extends an invitation for dinner instead. An e-mail was then found showing Leslie Stowle sending Tom Warner’s account an internet link to a hotel website in Hawaii. Tom email replies “that looks nice, make it happen.” We found an htm file containing hotmail accounts for hotdog918@hotmail.com labeled as the contact “Tom Warner”, and sweetdog918@hotmail.com labeled as the contact “Leslie Stowle”, where they message each other about vacation plans. Upon further examination of Tom Warner’s and Leslie Stowle’s workstation, an executable file called “eraser.exe” was found. An .xml file was also found showing a description of the file and its capabilities. A zip file titled “Earser57Setup.zip” was also found on on the PSC server.

A Cluster is the smallest unit of logical storage that is directly accessible by the operating systems file management system, consisting of one or more sectors. An E01 Image (Encase Image File Format) file keeps backup of various types of acquired digital evidences that includes disk imaging, storing of logical files, etc. When an investigator (or a Forensic Expert) uses Encase to create a backup of data available in the hard disk, a physical bit stream of the data is produced. A File Path is the general form of the name of a file or directory, specifies a unique location in a file system. A path points to a file system location by following the directory tree hierarchy expressed in a string of characters in which path components, separated by a delimiting character, represent each directory. A computer processor executes an instruction, meaning that it performs the operations called for by that instruction.
