TRACE
TRACE Forensic Toolkit is an open-source digital forensic analysis tool designed to simplify the investigation of disk images. The tool offers a user-friendly interface and supports key forensic functions like mounting disk images, extracting EXIF metadata, and file carving. It also provides a registry viewer and integrates with VirusTotal for malware checks. With support for multiple image formats like E01 and dd, TRACE is cross-platform compatible and allows investigators to analyze and verify disk images on Windows, macOS, and Linux.
TRACE includes features such as converting E01 images to raw format and verifying the integrity of disk images. Its modular design and compatibility with various file systems make it versatile for forensic examiners. It is a work in progress, with planned improvements for file search and playback features, but the current version is already a robust tool for digital forensics.
