Critical Warning (Digital Forensics)

🚫 NEVER analyze on live systems
Always use verified forensic images.
🔗 Maintain chain of custody
Document every transfer, access, and action taken.
💾 Preserve evidence integrity
Use write blockers to prevent modification of original media.
⚖️ Follow legal requirements
Consult with legal counsel when required.
📝 Document everything
Maintain detailed notes for potential legal proceedings.

Best Practice Reminder

Work from forensic copies, not originals.
Validate images using hash values (MD5/SHA-256).
Store evidence securely with controlled access.
