o efficiently bypass BitLocker encryption, a workstation needs to focus on:✅ Live memory acquisition (to extract decryption keys)✅ High-speed password cracking (brute-force, dictionary, or AI-assisted attacks)✅ TPM key extraction & forensic analysis
💻 System Design: The Ultimate BitLocker Decryption Workstation
🚀 Goal: Maximize GPU acceleration for brute-force attacks while integrating memory capture and forensic tools.
🖥️ Hardware Specifications
1️⃣ Processor (CPU) – High-Core Count for Multi-Threading
AMD EPYC 9654 (96 Cores / 192 Threads, 3.7GHz)
Why? GPU-based password cracking still benefits from a strong CPU for managing hashing algorithms like PBKDF2.
2️⃣ RAM – For Memory Dump Analysis
512GB DDR5 ECC
Why? Large memory capacity ensures smooth RAM acquisition and forensic analysis, especially with virtual machines running.
3️⃣ GPU – Password Cracking Power
🔹 8 x NVIDIA RTX 4090 24GB (NVLink Supported)
Why? Parallel brute-force attacks on AES-256 encryption using Hashcat.
Performance: Can attempt billions of password guesses per second.
4️⃣ Storage – High-Speed Data Processing
🔹 Boot Drive: 2TB NVMe Gen4 SSD (Samsung 990 Pro)🔹 Scratch Disk: 8TB NVMe RAID0 (2x 4TB) for real-time cracking🔹 Storage: 20TB HDD (for storing forensic images & case files)
5️⃣ RAID & Data Integrity
RAID Controller: PCIe 4.0 MegaRAID for RAID 1 & RAID 5
Purpose: Data redundancy + fault tolerance during analysis.
6️⃣ Motherboard – PCIe 5.0 Support for GPUs
ASUS Pro WS WRX80E-SAGE SE WIFI
Supports 8 GPUs & full PCIe 5.0 bandwidth.
7️⃣ Power Supply – Extreme GPU Load Handling
🔹 2 x 1600W Titanium PSUs
Why? Each RTX 4090 can pull up to 450W under full load.
🔍 Software Stack – Forensic & Password Cracking Tools
1️⃣ GPU-Accelerated Password Cracking
✅ Hashcat – Open-source brute-force / dictionary attack on BitLocker hashes.✅ ElcomSoft Forensic Disk Decryptor – Commercial-grade BitLocker recovery.✅ Passware Kit Forensic – Can extract BitLocker keys from memory & TPM.
2️⃣ Live RAM Capture (For Extracting Decryption Keys)
✅ Magnet RAM Capture – For on-the-fly memory dumps.✅ Belkasoft RAM Capturer – Specialized for volatile memory acquisition.✅ Volatility Framework – Analyzes memory dumps for BitLocker keys.

4️⃣ Full-Disk Forensic Imaging
✅ Autopsy – Open-source forensic suite for disk & file analysis.✅ X-Ways Forensics – Advanced forensic analysis of Windows systems.
🔌 Additional Features
Liquid Cooling for GPUs (prevents thermal throttling under long cracking sessions).
Dual Workstation Mode: Can be used as a password-cracking rig or a full forensic lab.
Modular Case for easy GPU upgrades (supports RTX 5090 in the future).
💰 Estimated Cost
💲 $45,000 - $50,000 (enterprise-grade components).
🔥 How This Workstation Solves the BitLocker Problem
🚀 Scenario 1: Extract BitLocker Keys from RAM
If the target system is running → Dump memory using Volatility → Extract key instantly.
🚀 Scenario 2: Brute-Force Attack on BitLocker
8x RTX 4090s perform trillions of hash calculations per second.
AI-based dictionary attacks predict passwords faster.
🚀 Scenario 3: TPM Exploitation for BitLocker Bypass
If TPM-only mode is enabled, use DMA attacks to extract the decryption key.
🚔 Who Needs This?
✅ Law enforcement & government agencies handling encrypted evidence.✅ Cybersecurity researchers testing password vulnerabilities.✅ Incident response teams working on ransomware recovery.
