Portable Timestomp-GUI is a lightweight, freeware Windows application designed to easily modify or completely delete the timestamp metadata of files and folders. Originally built as a graphical user interface (GUI) wrap-around for command-line timestomping utilities, it allows users to alter core file attributes without requiring an installation process. Core Capabilities and Features
MACE Attribute Modification: The utility allows users to manipulate the standard Windows file system timestamps: Modified (Last Written) Accessed (Last Read) Created Entry Modified (MFT Metadata Change)
Zero-Installation Portability: As a portable app, it runs directly out of an executable (.exe) file. It can be operated from a USB drive, cloud storage, or any local folder without altering the Windows registry or leaving operational traces.
Instant and Batch Editing: It offers an intuitive visual interface where users can select individual files or load multiple objects to apply uniform time attributes simultaneously.
Time Blanking: Some variations of the tool feature the capability to wipe the timestamps entirely, causing traditional forensic suites to show them as completely blank. Dual-Use Scenarios
Like many metadata editors, Timestomp-GUI serves two entirely different purposes depending on who is using it:
Administrative and Defensive Use: System administrators, developers, and photographers use timestamp utilities to correct metadata errors. Common scenarios include fixing timestamps corrupted by changing time zones, correcting files modified by unintended automated backups, or synchronizing project deployment dates.
Anti-Forensics and Offensive Security (Red Teaming): In cybersecurity, “Timestomping” is a recognized technique (categorized by MITRE ATT&CK as Sub-technique T1070.006). Threat actors or penetration testers use these tools to hide malicious payloads by mimicking the exact creation and modification dates of legitimate OS files in the same folder, thereby evading timeline analysis and basic forensic sweeps. Forensic Detection Realities
While tools like Timestomp-GUI instantly change what a standard user sees in Windows File Explorer (the \(STANDARD_INFORMATION</code> or <code>\)SI attribute), they often fail against modern digital forensics. Indicator Removal: Timestomp, Sub-technique T1070.006
