Certified Ethical Hacker (CEH) Practice Question

While monitoring a corporate WLAN, you see a flood of 802.11 deauthentication frames whose transmitter address does not match any authorized AP. Seconds later, clients reconnect and a 4-way handshake is exchanged. What wireless threat does this activity most likely represent?

  • A deauthentication attack that forces WPA/WPA2 clients to reconnect so the 4-way handshake can be captured for offline cracking

  • A CTS flood that abuses virtual carrier sensing to silence stations and create a denial-of-service condition

  • A KRACK key-reinstallation attack aimed at decrypting traffic by replaying handshake messages

  • A beacon flood that advertises thousands of fake SSIDs to exhaust client resources and confuse users
