Which of the following is a common wireless network-specific attack technique?

The correct answer is B. IV attack. IV (Initialization Vector) attacks target the WEP encryption protocol used in wireless networks - WEP reuses short 24-bit IVs, which allows attackers to collect enough packets to statistically crack the encryption key, making this an inherently wireless-specific vulnerability.

Explanation

IV (Initialization Vector) attacks target the WEP encryption protocol used in wireless networks - WEP reuses short 24-bit IVs, which allows attackers to collect enough packets to statistically crack the encryption key, making this an inherently wireless-specific vulnerability.

SQL injection (A) and Cross-site scripting (D) are web application attacks that exploit input handling in databases and browsers respectively - they operate at the application layer and have nothing to do with wireless protocols. Phishing (C) is a social engineering technique that works across any medium (email, SMS, voice) and is not specific to wireless networks.

Memory tip: Think "IV = Initialization Vector = Wi-Fi WEP weakness." The acronym IV can remind you of "Insecure Vacuum" - WEP creates a vacuum where the same IVs keep cycling back, letting attackers vacuum up enough data to break the key.
