Which of the following is a passive wireless packet analyzer that works on Linux-based systems?

OpenVAS is a vulnerability scanner used to detect security weaknesses in networked hosts, not a wireless packet analyzer.

Burp Suite is a web application security testing proxy and scanner focused on HTTP/HTTPS traffic, not wireless packet capture.

tshark is the CLI version of Wireshark and captures general network traffic on wired or wireless interfaces, but it is not designed specifically as a passive wireless reconnaissance tool.

Kismet operates passively by listening to wireless traffic without transmitting any packets, enabling covert wireless reconnaissance. It runs natively on Linux, captures raw 802.11 frames across channels, and never associates with an access point, making it the definitive passive wireless analyzer for Linux.
