Performing File Carving with Foremost

When to Use

• When recovering files from unallocated disk space or corrupted file systems
• For extracting evidence from formatted or wiped storage media
• When file system metadata is unavailable but raw data sectors contain evidence
• During investigations requiring recovery of specific file types from raw images
• As a complement to file system-based recovery for maximum evidence extraction

Prerequisites

• Foremost installed on forensic workstation
• Forensic disk image in raw (dd) format
• Sufficient output storage (potentially larger than source)
• Custom foremost.conf for specialized file types (optional)
• Understanding of file signatures (magic bytes) for target file types
• Scalpel as an alternative for performance-critical carving
