Analysis Summary
# Tool/Technique: Thorium Platform
## Overview
Thorium is a platform open-sourced by CISA designed to facilitate advanced malware and forensic analysis. Its purpose is to empower the broader cybersecurity community to orchestrate sophisticated analysis of binaries and other digital artifacts to better understand and address software vulnerabilities.
## Technical Details
- Type: Tool (Malware/Forensic Analysis Platform)
- Platform: Not explicitly stated, but implies environments used for malware analysis (likely supporting Windows/Linux binaries)
- Capabilities: Orchestrated use of advanced tools for malware and forensic analysis; scalable analysis of binaries and digital artifacts.
- First Seen: Implied release around July/August 2025 based on context with other CISA releases.
## MITRE ATT&CK Mapping
*(Note: Since Thorium is an analysis tool and not an adversary tool, it does not typically map directly to adversary TTPs. However, it supports defensive analysis.)*
* **Defense and Analysis Support:** Tools like Thorium support analysts in defeating adversary techniques.
