📡 Legacy Wireless Security: WEP Protocol Analysis

WEP (Wired Equivalent Privacy) was the original wireless security protocol, now known to be fundamentally flawed. This challenge introduces you to the cryptographic weaknesses that make WEP trivial to crack with modern tools.

🎯 What You'll Learn
  • ✓ WEP protocol structure and vulnerabilities
  • ✓ RC4 stream cipher weaknesses
  • ✓ IV (Initialization Vector) collision attacks
  • ✓ Wireless packet capture analysis
🔍 Challenge Overview

You'll analyze a captured WEP-encrypted wireless traffic dump to exploit the protocol's inherent weaknesses and recover the network key through statistical analysis of initialization vectors.

Historical Context: WEP was deprecated in 2004 due to fundamental cryptographic flaws, but understanding these vulnerabilities helps security professionals identify legacy systems and appreciate modern wireless security improvements.
