Master Steganography with OpenStego | CyberLabs007 Episode 36 🔒

Welcome to CyberLabs007 — your go-to resource for hands-on cybersecurity labs!

In this episode, you'll use OpenStego, a steganography tool that lets you hide sensitive data inside image files. This technique is used in both offensive and defensive cybersecurity, and understanding it is part of the Operations and Incident Response domain of the CompTIA Security+ (Exam SY0-701).

✅ What You’ll Learn:
What steganography is and why it’s used
How to hide and extract messages with OpenStego
How to detect possible steganographic files in an investigation
How attackers and defenders might use these techniques

🧠 Why This Matters:
Malicious actors use steganography to exfiltrate data or conceal commands, while defenders may use it to verify integrity or track tampering. Knowing how it works helps you think like an attacker — and defend like a pro.
