Hey security researchers!
I've released BareMetal-RAM-Dumper — a low-level x86 utility for dumping
physical RAM directly to disk, designed for Cold Boot Attack research.
What it does:
• Custom 512-byte bootloader (no OS needed)
• Boots via BIOS Legacy CSM
• Switches to Unreal Mode to access 32-bit physical memory
• Dumps RAM in 32KB chunks directly to USB drive
• BIOS INT 0x15 E820 for safe memory map parsing
• Real-time progress indicator
Cold Boot Attack Use Case:
Freeze a laptop's RAM to -60°C → quickly reboot from USB →
capture full memory contents for forensic analysis & crypto key recovery
How it works:
1. Stage1: 512-byte boot sector (loads Stage2 via INT 0x13)
2. Stage2: Main logic (memory detection, unreal mode, disk writes)
3. Writes to LBA 64+ on boot drive
Warning: This overwrites data starting at sector 64! Use a dedicated blank USB.
Built with pure Assembly (NASM) — no bloat, direct hardware access
GitHub: https://github.com/pIat0n/BareMetal-RAM-Dumper
License: AGPL-3.0
Perfect for:
Forensic researchers
Security auditors testing cold boot resilience
Students learning low-level x86
Penetration testers
Feedback & improvements welcome!
