Exam 312-50v11 topic 1 question 400 discussion

Actual exam question from ECCouncil's 312-50v11

Question #: 400
Topic #: 1

In this attack, an adversary tricks a victim into reinstalling an already-in-use key. This is achieved by manipulating and replaying cryptographic handshake messages. When the victim reinstalls the key, associated parameters such as the incremental transmit packet number and receive packet number are reset to their initial values.
What is this attack called?

A. Evil twin
B. Chop chop attack
C. Wardriving
D. KRACK

Selected Answer: D

Authentication Attacks - Key Reinstallation Attack (KRACK) The key reinstallation attack (KRACK) exploits the flaws in the implementation of the four-way handshake process in the WPA2 authentication protocol.The attacker exploits the four-way handshake of the WPA2 protocol by forcing Nonce reuse. In this attack, the attacker captures the victim’s ANonce key that is already in use to manipulate and replay cryptographic handshake messages. (P.2233/2217)

KRACK vulnerabilities: WPA2 has a significant vulnerability to an exploit known as key reinstallation attack (KRACK). This exploit may allow attackers to sniff packets, hijack connections, inject malware, and decrypt packets. The key reinstallation attack (KRACK) exploits the flaws in the implementation of the four-way handshake process in the WPA2 authentication protocol, which is used to establish a connection between a device and an AP. All secure Wi-Fi networks use the four-way handshake process to establish connections and to generate a fresh encryption key that will be used to encrypt the network traffic.
