After testing it against three different ransomware strains (including one that overwrote files with zeros), here is everything you need to know—when it works, when it fails, and how to use it like a forensic analyst. Let’s clear up the biggest misconception immediately.
Most people know Kaspersky for its antivirus engine (and the geopolitical noise surrounding it). Few know about a small, standalone tool quietly sitting in their installation directory that can perform digital necromancy.
File Carving. The Kaspersky Restore Utility scans the raw disk surface—bypassing the file system entirely. It looks for file headers, footers, and structural patterns (magic bytes for JPEG, DOCX, PDF, etc.). When ransomware encrypts a file, it usually writes the ciphertext over the original plaintext. However, due to how SSDs and HDDs handle wear leveling, TRIM commands, and slack space, fragments of the original file often remain.
