Which of the following tools is a wireless sniffer and analyzer that works on the Windows operating system?

Kismet is an open-source wireless network detector and sniffer that runs primarily on Linux and Unix-like systems, not Windows.

AirSnort is a Linux-based tool historically used to recover WEP encryption keys by passively monitoring transmissions.

Void11 is a Linux-based tool used to perform deauthentication and disassociation attacks against 802.11 wireless networks, not a sniffer.

AiroPeek, developed by WildPackets (later Savvius), is a Windows-native wireless LAN analyzer capable of capturing and decoding 802.11 frames, measuring signal quality, and diagnosing WLAN issues. It was widely referenced in security certifications as the primary Windows-compatible wireless sniffer, in contrast to the Linux-centric alternatives.
