Which of the following is a wireless network detector that is commonly found on Linux?

Kismet is a widely used Linux-based wireless network detector and packet sniffer that passively captures 802.11 traffic without transmitting, making it suitable for covert reconnaissance and network auditing. It supports multiple wireless interfaces and can detect hidden SSIDs by analyzing probe responses. It is a staple tool in wireless security assessments on Linux platforms.

Abel (as in Cain and Abel) is a Windows-based password recovery and network sniffing tool, not a wireless network detector and not Linux-native.

NetStumbler is a Windows-based active wireless network scanner that transmits probe requests, and it is not commonly available or used on Linux.

Nessus is a vulnerability scanner used for network and host-based vulnerability assessment, not a wireless network detector.
