How Hackers Exploit Weak Encryption Keys 🔓 | Cryptography Failures Uncovered

In this video, we explore Cryptographic Failure — one of the OWASP Top 10 vulnerabilities — and show you real-world demos of how weak cryptography can lead to serious data breaches.

🔍 You’ll learn:
- How MD5 hash cracking can reveal passwords in seconds.
- How a weak JWT signing key lets attackers forge tokens and bypass authentication.
- Real-world case studies like MSI’s leaked firmware key (2023) and Freecycle.org’s MD5 breach.
- Simple and effective remediation steps to prevent cryptographic failures.

🧠 Key Takeaways:
Weak encryption = easy data breach
Avoid weak algorithms like MD5, SHA-1
Always verify algorithm in headers and rotate keys regularly
Use short TTL (token expiry) and secure key storage
