Kodak Color management for Windows file Hint FILE START

Hunt Hypothesis

This rule identifies the presence of Kodak Color Management for Windows files, which may indicate the use of legitimate software for file staging or as a cover for malicious payloads. Proactively hunting for these files helps the SOC team distinguish between benign color management utilities and potential living-off-the-land techniques used by adversaries to blend into the environment.

False Positive Guidance

• Kodak Print Manager Installation/Update: When IT administrators deploy or update the Kodak Print Manager or related Kodak software (e.g., via SCCM, Intune, or manual MSI installation), the installer may extract or create configuration files, license keys, or hint files that match the “FILE START” signature.
  • Filter/Exclusion: Exclude files located in standard Kodak installation directories (e.g., C:\Program Files\Kodak\, C:\Program Files (x86)\Kodak\) or exclude processes associated with Kodak installers (msiexec.exe, setup.exe from Kodak paths).
• Legacy Application Dependency: Older enterprise applications (e.g., specific CAD, medical imaging, or retail POS systems) that rely on Kodak color management libraries may load or create temporary hint files during initialization or color profile calibration.
  • Filter/Exclusion: Exclude files created by known legacy application processes (e.g., AutoCAD.exe, DICOM viewer executables) or files located in application-specific temporary directories (e.g., %TEMP%\Kodak\, C:\Users\<user>\AppData\Local\Kodak\).
• Scheduled Color Profile Sync Job: A scheduled task (e.g., via Windows Task Scheduler or a custom script) that synchronizes ICC profiles or color management hints across a fleet of workstations or print servers.
  • Filter/Exclusion: Exclude files created by specific scheduled tasks (e.g., task name containing “KodakColorSync” or “ProfileUpdate”) or exclude files in the Windows Color Management system directory (C:\Windows\System32\spool\drivers\color\ or C:\Windows\Color\).
• Backup/Restore Operations: During full system backups or restores (e.g., using Veeam
