⚙️ Hypervisors: VMware & VirtualBox
Your competition platform explained⏱ ~3 min
CyberPatriot competition images are distributed as VMware files (.vmx, .vmdk). You need a hypervisor to open them. Two main options exist:
VMware Workstation Pro (Recommended for Competition)
- •Now free for personal and educational use (since May 2024, after Broadcom acquired VMware)
- •Download from vmware.com — search for 'VMware Workstation Pro download'
- •Best compatibility with official CyberPatriot image files
- •Supports snapshots, drag-and-drop, shared folders, and VM isolation
VirtualBox (Free Alternative)
- •Made by Oracle, always free and open-source
- •Can open VMware .vmdk disks (with manual setup)
- •Great for practice and learning; use VMware for actual competition images
Important VMware Files — Don't Modify These!
| File Extension | What It Is | Why It Matters |
|---|---|---|
| .vmx | VM configuration file — tells VMware how much RAM, what hardware to simulate | Opening this file in VMware opens the VM |
| .vmdk | Virtual disk file — the simulated hard drive with the OS and all data | Corrupt this = VM won't boot |
| .nvram | VM's virtual BIOS settings | Stores boot order and BIOS config for the guest |
| .vmss / .vmsn | Snapshot files | Stores saved VM states — don't delete |
⚠ WarningNever rename or move individual VM files while the VM is running, and never delete .vmdk files. Always move the entire VM folder together.
Checksums — Verifying Your Download
Before each CyberPatriot round, teams must verify the checksum of downloaded images. A checksum is a mathematical fingerprint of a file.
- •If the downloaded file's checksum matches what CyberPatriot published → file is intact
- •If checksums differ → the file was corrupted or tampered with during download → re-download
- •Common algorithms: SHA-256 (most common today), MD5 (older, still used for verification)

Compare it character-by-character with the hash your system generates. They must match exactly.
