You may have heard of the term artifacts but perhaps not when it applies to Microsoft Windows. Artifacts are not traditional user data that people may be familiar with — artifacts are system created data. Artifacts are areas in a computer that gather information about relevant user activities that the user is executing. To recognize that the system creates its own data about the user, is to understand the vastness of computer forensics. I do not plan on covering every known artifact and its purpose.
I believe it is more beneficial to focus on the forensically important ones and to provide you with a basic understanding of them. When it comes for forensics, there is a few things artifacts can tell us about a user on a system. However, artifacts can tell us about account usage, browser usage, file downloads, network activity, and program execution as well.
Most information I will be talking about cannot be put to true forensic use without proper software. Forensic software parses through everything you could need for most part.
However, much like anything, an understanding of key concepts is the place to begin. Just like you should know how to do basic arithmetic before punching numbers in a calculator! Enough of that though, lets get right to it! Computers constantly track activities that the user is executing and forensic examiners use that to their advantage. Artifacts are not native to the Windows OS. These areas in other systems can differ by the types of artifacts present, its location in the system, and its naming convention.
In a separate article, I will cover details about the Windows Registry, what it is, and the stash of amazing artifacts it holds for forensic examiners. The Registry belongs with this topic but I want to avoid making this article too long. There is no particular order of importance here but for the most part, the artifacts that I will cover are what we want to look for in general.
It contained file information such as file names, file paths, dates, and sizes. The naming convention appears to be random and takes some logic to determine what file is what. Forensic tools can parse through this area and recover deleted files for you. However, once files are overwritten in unallocated space, not even forensic software can ertugrul season 3 episode 36 english subtitles it back—its gone gone.
Unallocated space can get tricky to explain, but I found a good example here. So, forensically you can see what files were up for deletion, at what time, and how many at a time. Every account has their own SID, which generally appears as S, followed by a string of numbers.
Otherwise known as LNK files, link files are essentially shortcuts that point to executable files. Lnk files are both user created and system generated. Windows creates lnk files when a user opens local files. A file can be removed, copied over to a USB, or shared over a network. Link files show that the original file existed at some point on the system. The original file may no longer be available, but the link file tied to it has pertinent information. In the case of being stored on a machine or network, those details are available as well; serial numbers, mac addresses, volumes, etc.
Important Artifacts In Windows-I
This is very important metadata that forensic examiners do not overlook most of the time. This would be a good time to delve into ShellBags. Windows Shell Bags have been around only since Windows XP but are interesting in the way they function. Shellbags retain information about user activity on the system. They track positions of windows that are opened on a system as well as if someone burrowed into a directory.
This is tracked on the local machine and attached devices.Drawing errors made by video cards are refered to as visual artifacts.
These artifacts can be caused both by software and hardware problems. If you see artifacts during the power-up screens before your operating system loads then you know it has nothing to do with drivers.
There are any loaded yet. If you're seeing visual artifacts in just one program then it may be a software problem with that program. But if you have artifacts in many programs then you may have a driver problem or bad hardware.
If you're seeing artifacts only after the operating system loads then the first thing you should do is the standard "update your drivers" drill: update your motherboard chipset driversand uninstall your display drivers and then reinstall the latest display drivers. Updating your drivers can sometimes fix your problems and you should always do this even if you think that your hardware is responsible.Getting Started with the SIFT Workstation Webcast with Rob Lee
You should exhaust the easy software solutions before guessing that you have bad hardware. It's also a good idea to open up your computer and make sure all the fans are working. Overheating is a common cause of artifacts so you should check that any fan on your video card is rotating. The temperature of your video card depends on what kind of program you are running. Most video cards are relatively cool when you are running 2D programs.
The temperature of the video card increases when running 3D programs like games. If your artifacts only show up after a few minutes of playing games then overheating is usually the cause. The silicon chips on your video card run slower at higher temperatures. The hotter the chips get the more trouble they have keeping up at their standard clock rates.
You can prove that it's an overheating problem by running your computer with the case open and aiming a desk fan at the video card. If the artifacts go away then you know that you have an overheating problem. Another thing you can try to reduce artifacts is to underclock your video card. Reducing clock rates lowers the temperature of the chips and often allows weak ones to work properly.
There are instructions on how to underclock your video card on this page. And if you're overclocking your video card then you should back off on your overclock. Overclocking often causes artifacts.Keep in touch and stay productive with Teams and Officeeven when you're working remotely.

Windows Systems and Artifacts in Digital Forensics, Part II
In reply to DaveM's post on May 22, This site in other languages x.The login workflow was far from the only change in this anniversary update, however. In this blog, Training Director Jamey Tubbs describes other Windows operating system changes that could affect your forensic examinations. InMicrosoft announced that Windows 10 will be the last operating system they produced:. With this announcement, it appeared that Microsoft would be taking a page from Apple and OSX on how it does updates.
This could be a good thing for examiners…or it could be a bad thing. Microsoft announced it will be releasing two major updates a year and has been naming them YYMM, as Wikipedia details :. Perhaps most importantly to forensic investigations, when Microsoft updates Windows, file locations and registry keys move or change, and new registry keys are created. It can be used to restore your system to the old version of Windows, should something go wrong with the new version. Windows will automatically delete the Windows.
In addition, new registry hives are created and artifacts, such as the operating system install date, are changed to reflect the upgrade date and time. If the Windows. If, however, you look at the Windows. The takeaway from this is: if the Windows.
However, if the Windows. This registry key will reflect the current version of Windows This is important to know, as different versions of Windows 10 have different features, registry keys, etc. Of course you do. But is what Windows tells you is the install date and time accurate to what you think it is? This registry key will tell you when the current version of Windows 10 was installed. But, is this really the date and time of the original installation?
These registry keys will tell you when the operating system was upgraded FROM and the date and time it took place. In the figure below, you can see the registry keys are easily identifiable:. Within this key, you can see the ProductName key has the value Windows 8.

What Happens During a Win 10 Upgrade? Related Posts Blog. Industry News April 15, Industry News April 13, Linux and Windows Server both implement similar technologies within their kernel and core operating systems. The difference comes from the platform and workloads that run within the containers.
When a customer uses Windows Server containers, they can integrate with existing Windows technologies, such as. NET, and PowerShell. Containers were introduced to the platform with Windows Server To use containers, you'll need either Windows Server or the Windows 10 Anniversary update version or newer. Read the System Requirements to learn more.
Windows Server container image usage is determined by reading the number of virtualization guests supported for that edition. Additional terms and restrictions in the Windows IoT Commercial Agreements apply to your use of Container Image in a production environment.
Please read the container image EULA to understand exactly what is permitted and what is not. Windows container images are common across both Windows Server containers and Hyper-V isolation.
The choice of container type is made when you start the container. From a developer standpoint, Windows Server containers and Hyper-V isolation are two flavors of the same thing.
They offer the same development, programming, and management experience, and are open and extensible and include the same level of integration and support with Docker. A developer can create a container image using a Windows Server container and deploy it in Hyper-V isolation or vice-versa without any changes other than specifying the appropriate runtime flag.
Windows Server containers offer greater density and performance for when speed is key, such as lower spin-up time and faster runtime performance compared to nested configurations. Hyper-V isolation, true to its name, offers greater isolation, ensuring that code running in one container can't compromise or impact the host operating system or other containers running on the same host. This is useful for multitenant scenarios with requirements for hosting untrusted code, including SaaS applications and compute hosting.
Aside from on IoT Core and IoT Enterprise hosts after accepting additional terms and restrictionsthis feature is only meant for development and testing. You should continue to use Windows Server as the host for production deployments.
By using this feature, you must also ensure that your host and container version tags match, otherwise the container may fail to start or exhibit undefined behavior. Windows container base images contain artifacts whose distribution is restricted by license.As Windows has evolved over time several artifacts have appeared that can highlight when programs or applications were executed, and which user executed them.
The information provided by these artifacts can illuminate a timeline of events that occurred on the Windows system answer questions such as:. The Actionable Intel tab has been redesigned to provide easier access to all of the artifacts parsed.
All of the artifacts displayed in Actionable Intel from previous version of BlackLight R2 and earlier are available, as well as the newly parsed items. BAM controls the activity of background applications. DAM, which moderates desktop processes, was created to ensure consistent long battery life for devices that support connected standby you know when the screen is off, but the device is still on.
A folder for each user named by SID provides the following information:. The information is stored in registry. SRUM monitors desktop applications, services, window apps and network connections. SRUM data is stored in the registry, with historic information contained in a database.
The information tracked includes:. Some of this information may be of use forensically, specifically for data theft investigations or when looking for malicious applications responsible for data exfiltration. Data stored can also shed light on peer-to-peer application usage.
Forensically, SRUM data can be used to determine:. UserAssist allows investigators to see which programs were recently run on the Windows system. Forensically, UserAssist can help determine the following:. You can also see an executable launched from a removable device. Examining these Windows artifacts provides insights into programs executed on the computer, network activity, and ties this information to specific user accounts.
