Morris, an attacker, wanted to check whether the target AP is in a locked state. He attempted using different utilities to identify WPS-enabled APs…

The wash command-line utility is a component of the Reaver toolset, specifically designed to scan for wireless access points with Wi-Fi Protected Setup (WPS) enabled. It actively surveys the wireless environment and reports on nearby APs, providing crucial details such as their BSSID, ESSID, channel, and WPS version. Most importantly for the scenario, wash indicates the WPS lock status, which directly addresses the attacker's goal of determining if the target AP is in a locked state. This makes it the precise tool for the task described.

B. ntptrace: This is a diagnostic tool for the Network Time Protocol (NTP), used to trace the chain of time servers, not for wireless network analysis.

C. macof: This tool is part of the dsniff suite and is used to flood a switch's MAC address table, not to discover or analyze wireless APs.

D. net view: This is a Windows command used to list domains, computers, or shared resources on a network; it does not perform wireless scanning or WPS detection.

1. Official Vendor Documentation: The wash utility is part of the Reaver project. The official documentation describes its function: "Wash is a utility for identifying WPS enabled access points. It can also estimate the strength of the signal from the AP and whether or not the AP is locked."
