The database administrators machine will be a little tricky as it is already considered to have malware. Good malware will want to stay on the computer and be looking out for forensic type activities. The first part is to assess from the above steps is if the machine is able to be shut down safely and not lose any data. Whatever data that can be attained should be documented and considered before moving forward.
Assuming the machine can be shut down properly and without alerting the malware of the current investigation, the following steps should be taken to image the hard drive:
1. Safely remove the hard drive or at least the outer computer shell to access the hard drive. Use a static guard mat and ground everything, especially after opening up evinced from a static free bag.
2. With the forensic computer off, attach to the evidence hard drive using a professional read only, write-blocker to assure the evidence doesn’t get tampered with or changed in the process of imaging.
3. Start up the computer forensic machine.
4. Before making an image, run a hash value (MD5 or SHA) on the evidence and document everything.
5. Using Encase, FTK Imager or any other

A copy of the image file should be opened in a virtual environment matching the notes of the initial investigation of this computer. From here the most efficient starting point is to look at the Windows registry. A forensic investigator can characterize the valuable data from the Windows registry in five groups; system information, application information, network information, attached devices and history list (Alghafli, Jones, & Martin, 2014). This will give an investigator a good idea of whether the initial assessment of this computer is accurate and more or less time should be spent on this computer. Also, having a physical Windows machine that can be built as a backup is a good idea as some malware can detect
As you can see there is no perfect crime. The littlest piece of hair or paint or anything left behind can be found. Suspects often miss these tiny peieces of evidence and while they looked over it, it is still lurking at the crim scene. It is guarenteed that a Crime Scene Investigator will find this evidence no matter how small and use it to find, prosecute, and convict a criminal.
There is a wide range of Linux forensic software available. There are single tools like file carvers, or there are comprehensive collections of tools. In the following, some of the most popular Linux forensic tools are described. The focus is put on The Sleuth Kit because it is organized according to the different filesystem layers. This provides an interesting insight on how forensics is done on filesystems.
The first finding was a medium priority that was a cryptcat.exe file this program can potentially be used to remote access the program. The second finding was a Psh.exe file that was a very high priority it was a Trojan Horse Dropper named Generic4.BVMA, this really do some damage to the system by crashing it or altering it. Thirdly, I found a medium priority that was a astlog.exe file that is develop by NirSoft, the file can be a harmful program Logger.IAC that is an adware software and attackers can misuse this to get your passwords on your system. The fourth malware I found on the scan was a high priority from the Isadump2...
The book gives a general overview of the field of forensic science. The sections of the book include “The Scene of the Crime; Working the Scene--The Evidence; Working the Scene of the Body Human; Working the Scene--Different Stages; and Working the Scene--Different Skills (Genge vii-viii). Included are instructions on what professionals should do upon arriving at a crime scene, what items to bring with them, how to protect the crime scene, and how to protect the evidence from contamination. In addition to writing about the subject of forensic science, the author also included several appendixes and suggested readings to help the reader learn even more information about the subject. In addition, the author included a list of colleges that offer programs in the field of forensic science.
Carolyn Foster Segal, a Pennsylvanian English teacher, wrote “The Dog Ate My Flash Drive, and Other Tales of Woe.” Segal explains that her students don’t follow her class syllabus and sign on her door about late work. Her students insist on putting their efforts into making excuses rather than doing the work. She mentions that there are certain topics that the excuses fall under. Segal begins to list different scenarios that her students have come up with. She mentions that she has had excuses from coughing up blood, to relatives dying, to a chainsaw accident.
Collection of evidence is usually a term designated to refer to the collection of physical evidence, government agencies such as police or environmental protection departments will have their own methods for the collection, storage and conservation of physical evidence and it is the responsibility of forensic personnel to adhere to these set guidelines. General principles which are shared amongst various agencies include, the creation of contemporaneous notes, recording the collection of evidence via photographing, videotaping and/or audiotapes, preserving the crime scene by sealing off the location and only allowing designated personnel to enter, avoiding contamination of the crime scene by investigators through the use of full body covering and also preventing cross-contamination with the scene and any suspects.
There are various programs that can be used for recovering deleted files such as UndeletePlus, Disk Digger, and EnCase Forensics, which are associated with different success rates and particular functions. UndeletePlus is a program that is available for $29.95 and is very easy to use since it involves selecting a drive and clicking the Scan button. The program will then list any or all deleted files it finds or discover in the recovery process (Easttom & Taylor, 2011, p.287). On the contrary, DiskDigger is a freeware, which has a wizard interface that takes the user through the process. This involves identifying the drive to scan, the type of search to be conducted, and the kind of files to search. EnCase Forensics the leader in digital forensics and available for $2,995 since it incorporates various features such as ...
The data a computer forensics acquisition tool collects is stored as an image file in one of three formats. Two formats are open source and the third is proprietary. Each vendor has unique features, so several different proprietary formats are available. Depending on the ...
What did they do ? Before we talk about it any further, we have to know some definitions that we use in digital forensics and digital evidence, not only two of them but the others too. This chapter will explain about it . Before we talk about it any further, we have to know the definition of what we are talking about. In the introduction we already know what digital forensic and digital evidence shortly are. In this chapter, we will more explore what they are, and some state that we found when we search about digital forensic and digital evidence. Computer forensics is a broad field and applied to the handling of crimes related to information technology. The goal of computer forensic is to securing and analyzing digital
Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
In order to wipe out computer crimes, an agency specialized in computer crimes should be at task to take care of such crimes and special devices provided to them in their lab. The devices they have available is what they will use in curbing the crimes hence the need to provide them with sophisticated devices.
The biggest challenge investigators face and who is involved with high tech crime is the fast-paced constant evolving nature of technology. When companies come out with new devices or new versions of old devices which is almost all the time, and those who gather digital evidence must remain current to be able to locate and preserve all potential evidence. As technology evolves the capacities of these devices will rapidly increase while their form factor grows continually smaller. Investigators must preserve digital evidence to make sure it is suitable for presentation in court as well. Investigators must first never change a crime scene or alter evidence. It is their goal to document and preserve the scene exactly as it was when the crime occurred. Extreme caution and care is needed because the mere act of documenting or cataloging a crime scene means that investigators are interacting with the scene. The second concern is the physical fragility of the evidence. Care must be taken to keep items from getting wet, stepped on etc, this can also be applied to digital evidence. Investigators have been able to examine hard disk drives that have been through fires because the drives are usually air and water tight and impervious to temperatures into the thousands of degrees. The third issue is that digital evidence can be lo...
