LNK files, commonly known as shortcuts, play a crucial role in digital forensics by serving as metadata resources utilized by the Windows shell. These files contain valuable information that can provide insights into user activities and file access history. Understanding the significance of LNK files and how to extract and analyze their metadata is essential for forensic investigators seeking to uncover valuable evidence.
What is Lnk file?
The ".lnk" file is a shortcut file used in Microsoft Windows operating systems. It stands for "Link." When you create a shortcut to a file, folder, program, or website, Windows creates an .lnk file that points to the target item. This allows users to access the target item quickly without having to navigate through the file system.
"During a forensic examination of a hard drive, LNK files can determine what programs and files a user were accessing on their computer."
Location and Command:
To access LNK files, forensic investigators can navigate to the following locations:
Windows Recent Folder: cd C:\Users\<User>\AppData\Roaming\Microsoft\Windows\Recent\
Office Recent Folder: cd C:\Users\User\AppData\Roaming\Microsoft\Office\Recent\
Copy Artifacts: (Manually copying artifact and taking home to analyze)(from live system)
use copy command in cmd (for copying)
Information Contained in LNK Files:
LNK files contain a wealth of metadata, including:
Original path of the target file
Timestamps for the target file and LNK file (modification, access, creation)
Size of the target file
Attributes associated with the target file (read-only, hidden, system)
System name, volume name, volume serial number, and sometimes MAC address of the system on which the LNK file is present
Information indicative of whether the target resource is local or located on a remote computer
Forensic Analysis and Artifact Extraction:
Forensic analysis of LNK files can be conducted using specialized tools such as Kape, which facilitates artifact collection and parsing in real-time. Alternatively, manual extraction and preservation of artifacts enable thorough examination in a controlled laboratory environment.
In conclusion, understanding the significance of LNK files and their role in digital forensics is crucial for uncovering valuable evidence and gaining insights into user behavior and activities.
