Certified Ethical Hacker – CEH – 312-50 – Question266

In 2007, this wireless security algorithm was rendered useless by capturing packets and discovering the passkey in a matter of seconds. This security flaw led to a network invasion of TJ Maxx and data theft through a technique known as wardriving.
Which Algorithm is this referring to?


A. Wired Equivalent Privacy (WEP)
B. Wi-Fi Protected Access (WPA)
C. Wi-Fi Protected Access 2 (WPA2)
D. Temporal Key Integrity Protocol (TKIP)

Correct Answer: A

Explanation:

WEP is the currently most used protocol for securing 802.11 networks, also called wireless lans or wlans. In 2007, a new attack on WEP, the PTW attack, was discovered, which allows an attacker to recover the secret key in less than 60 seconds in some cases.
Note: Wardriving is the act of searching for Wi-Fi wireless networks by a person in a moving vehicle, using a portable computer, smartphone or personal digital assistant (PDA).
