Which artifact is commonly used to store image thumbnails and is often checked in forensic investigations?

• A. Malvertising
• B. Hiberfil.sys
• C. Thumbs.db
• D. System Restore Points

Answer: (C)

Thumbnail caches are a key source of evidence because they show what images were present or viewed on a system, even if the originals have been altered or removed. The artifact that directly stores these image thumbnails in Windows is Thumbs.db. This hidden system file sits in folders that contain images and caches small bitmap previews for the files in that folder, making it a common item investigators check to quickly verify image content and reconstruct activity. Other options aren’t about per-folder thumbnail caching: Malvertising is about malicious online ads; hiberfil.sys is a memory image used for hibernation; System Restore Points are backups of system state. So Thumbs.db is the typical thumbnail cache investigators examine.
