Learning about artifacts in Windows is crucial for digital forensics examiners, as Windows accounts for most of the traffic in the world (9. Windows as their operating system as of 2. Windows and will have to collect evidence from it in almost all cyber- crime cases. Below, we will discuss several places from which evidence may be gathered and ways to collect information from Windows. Windows actually provides a great abundance of artifacts and being aware of these artifacts is helpful not only for examiners but for companies and individuals (just to name a few reasons) trying to permanently and irrevocably erase sensitive information or perform informal investigations. Before we start, we have to mention that collecting evidence is not the sole challenge to examiners; the challenge is to locate and identify, collect, preserve, and interpret the information; whereas collecting it is only one piece of the puzzle. In this paper, we will only be able to have a glimpse of this wealth of artifacts but its forensic significance will be immediately unveiled to us. The things you will find in this article. In the first part of this series we are going to discuss the Windows registry, its structure, backups and supporting files, examples from case files which reveal how instrumental the registry might be in prosecuting suspects, and some open source tools. Registry. What is the Windows registry and what is its structure? The Windows registry is an invaluable source of forensic artifacts for all examiners and analysts. The registry holds configurations for Windows and is a substitute for the . INI files in Windows 3. It is a binary, hierarchical database and some of its contents include configuration settings and data for the OS and for the different applications relying on it. The registry not only keeps records of OS and application settings but it also monitors and records user- specific data in order to structure and enhance the user’s experience during interactions with the system. Most of the time users do not interact with the registry in a straightforward manner, but they interact indirectly with it via installation routines, applications, and programs, such as Microsoft Installer files. Nonetheless, system admins have the capability of interacting directly with the registry via regedit. Windows. Figure 1: How the Windows registry looks like through the eyes of the registry editor, along with the registry’s nomenclature. Figure 1 gives the impression that the structure of the registry is the much familiar folder- based one, but this is merely an abstraction designed by the registry editor. In reality, the registry is just a collection of files located on the user’s hard drive. The registry files in charge of the system and the applications on the user’s machine are located in the following path: Local Disk: \Windows\system. Windows user profile directory called ntuser. Furthermore, Figure 1 reveals that the binary structure of the registry is based on cells, the notable ones being keys and values. Although additional cell types exist, it can be said that they act as pointers to other keys (subkeys) and values. Values encompass data and they do not direct to other keys. Registry hives and their supporting files as a useful additive for forensic analysts. Keys, subkeys, and values are typically part of different hives, which are logical groups of the former and have a set of supporting files that encompass backups of their data. User profile hives can be found in the HKEY. Each user on a machine has his/her own hive, which is responsible for his/her user profile. Below, we have enumerated some extensions of supporting files and have shown what information to expect from such a file extension: No extension = a thorough replica of the hive’s data. Extension . alt = a duplicate of the HKEY. It should be noted that the system key is the sole key whose backup files use this file extension as it is a crucial hive. Extension . log = a record of modifications in the hive’s keys and values. Extension . sav = a backup replica of a hive. After discussing the types of supporting files and what data they hold, we can move on to show what file names the supporting files of the standard hives have. Below is a graphic (Figure 2) that illustrates the standard hives and their supporting files. Points of interest for forensic analysts in the registry’s key cell structure. Deleting a registry key would not make it “go” somewhere but it would rather cause its size value to be set to a positive one while undeleted keys have a negative value. Essentially, the space consumed by the registry keys gets labeled as available and it becomes possible to overwrite it. From the point of view of a signed integer, a registry key has a negative value but from a hexadecimal point of view, the key structure is indeed positive. The code “Unpack(“l”,$dword)” may be employed to parse the DWORD value as a signed integer using Perl. Keys contain the useful Last. Write time, which pinpoints when the last modification of the key took place. Modification may consist of changes to an existing subkey or value, the deletion of existing subkeys or values, or the creation of new ones. Figure 3 reveals the most notable key cell structure elements from the point of view of a forensic analyst. Their size in bytes and their offset are also included in the illustration. Some preliminary information: Registry keys typically begin with a four- byte double word that contains the size of the particular key. After the double word, there is a key node identifier “nk,” which tell us that what we are looking at is a key and not a value. Subsequently, there is a two- byte value that reveals the node type. The suspects were a man and his wife who bought goods from the Internet with pilfered credit card numbers. They were detained as a result of a controlled drop of commodities ordered from the Internet. When ntuser. dat, the registry, and the protected storage system provider were scrutinized, a list of numerous names, addresses, and credit card numbers were found. It turned out that the information in the list was applied online to purchase goods as well, and after an additional investigation it was concluded that these credit card numbers were used illegally, without any permission from their owners. The data retrieved from the registry was sufficient to exact more search warrants which led to the arrest of 2. The development of the events turned out to be the following: All defendants pled guilty to organized crime accusations and served time in jail, which may have not been possible without the help of the Windows registry. Child pornography. Guests at a hotel located in a little town near Austin, Texas, called the law enforcement authorities after seeing a person, who looked intoxicated, walking around the hotel naked. When the law enforcement officials arrived after the 9. The picture was projected through a laptop that had a projector attached to it. In close proximity to the laptop, there were two external hard drives. The individual who was already in the room was surprised by the entry of the police and he asserted that the laptop was his but that the external drives belonged to his intoxicated fellow and had nothing to do with him. The equipment was immediately confiscated and sent for analysis. Forensic clones were created from the laptop and the two external hard drives without delay. The initial analysis of the external hard drives revealed the existence of pictures and movies of child pornography on them. Consequently, the forensic analysts had to find out whether any of these external drives were connected to the laptop of the individual asserting that he had nothing to do with them. Thus, the laptop’s system registry file was examined to match any entries in the USBStor key with the external drives. This turned out to be a fruitful examination, as listings for the external drives were found as well as their hardware serial numbers. Following these steps, the forensic analysts had to determine whether their results were authentic, so they linked the suspect’s external drives to their lab’s computer system, using a freshly installed version of Windows. To avert any alteration to the clones of the EHDs a write blocker was linked between the two drives and the system. Lastly, they examined the clone’s system registry file and the USBStor keys and came to the same conclusion, that the EHDs listings were identical to the defendant’s, in addition to having the same hardware serial numbers, and this proved that at some point in time the EHDs were connected to the suspect’s laptop. Ultimately, the culprit was sentenced for possessing child pornography. Using open source tools for the examination of the Windows Registry. Modules. The Win. Tie. Registry is a Perl module that digs out data not only from local systems but also from remote ones. It can be used on live Windows systems. Equivalent to this is the Python module winreg, which is presented for the achievement of the same goal. However, tools like Win. Tie. Registry are not cross- platform and will not work on default OS X or Linux installations, as they depend on the native Windows API. There are many Perl scripts that take advantage of the Win. Tie. Registry Perl module, such as regscan. You may also want to create your own Perl scripts that will collect the Last. Write time from the registry hives so you can sort and parse the information in any way you like. Considering you have images collected from the system, the Perl module Parse: :Win. Registry seems like a good choice, partially because it is cross- platform. The Win. 32: :Tie. Registry rests on the shoulders of the API offered by Windows systems and grants us entry into the registry information on the live systems, while the Parse: :Win.
