While performing a wireless security engagement, you discover that a router is configured with a built-in connection feature that bypasses typical passphrase complexity. Which tactic exploits this design flaw to gain network access?
Force all connected systems offline repeatedly to eventually extract the secret key
Trick an employee via phone into revealing the access credentials
Record a data exchange between a client and the router, then apply a passphrase dictionary
Continuously attempt the short numeric possibilities recognized by the device until the correct one is found
By cycling through a small number of numeric possibilities, an attacker exploits how WPS drastically reduces the potential combinations. Capturing and cracking a handshake uses extensive guessing for standard passphrases. Social engineering involves manipulating someone into revealing credentials, which does not directly target WPS. Disconnecting machines forces reauthentication but does not reveal the administrator’s key.
