SIGINT Tools

The kit the operator reaches for in SIGINT collection and analysis. Tooling rotates; the headings hold as the capabilities the operator needs covered.

Tool	Purpose
gqrx / sdr++	SDR receivers; demodulation and waterfall display.
gnuradio	SDR signal-processing toolkit; build custom demodulators.
inspectrum	Visual signal analysis for captured RF.
universal-radio-hacker (URH)	Protocol reverse engineering for unknown RF.
rtl_433 / multimon-ng	Decode common ISM-band protocols and pagers.
kismet	Wireless network detector and 802.11 / Bluetooth / Zigbee passive collector.
wireshark + airodump-ng	802.11 capture and analysis.
hackrf, bladerf, usrp	Hardware SDR platforms.
