KRACK vulnerability is associated with which security protocol?

• A. TLS
• B. WPA3
• C. WEP
• D. WPA2

Answer: (D)

KRACK stands for Key Reinstallation Attacks and targets the WPA2 Wi‑Fi security protocol. The flaw lives in the WPA2 four‑way handshake that devices use to establish the session key. By manipulating certain handshake messages, an attacker can reinstall the same key, which can allow decrypting, replaying, or injecting traffic on a protected Wi‑Fi network. TLS operates at the transport layer and isn’t the target of this handshake flaw, and WEP is an older, insecure protocol unrelated to this specific vulnerability. WPA3 is the newer standard designed to address weaknesses in WPA2, but the KRACK issue itself is specific to WPA2.
