Intelligraphics.com Bloodhound Wi-Fi Packet Sniffer/Injector for Network Characterization, Surveillance, and Law Enforcement

802.11-based Wi-Fi is the leading communication mode in homes, public areas, offices, and in industrial sites

In 2017 and beyond, analysts, agencies, and security experts are all in agreement that threats to public safety, critical infrastructure, and data will rapidly escalate. The widespread proliferation of IoT and other wireless devices create enormous numbers of vectors and entry points for malicious activities including keylogging, malware, DDoS, IP spoofing, man-in-the middle (MiTM), and other attacks.

As criminals become more sophisticated in their means and methods, agencies and law enforcement face even greater challenges protecting lives and property. What’s needed is a specialized tool to add to the law enforcement and IT arsenal, one that provides a way to wirelessly collect and inject data into Wi-Fi-based traffic. Such a tool, a Wi-Fi sniffer/injector would enable agencies and IT to become their own MiTM.

A Wi-Fi sniffer is a device that passively listens and records information exchanged in a targeted Wi-Fi channel. A Wi-Fi injector actively transmits data into a Wi-Fi channel, then records and analyzes the response. Intelligraphics provides a mobile Wi-Fi device driver for TI WiLink™ and select Qualcomm® chipsets that enables customers to create a solution stack for a truly portable, mobile wireless sniffer/injector. It features a single Wi-Fi driver that can either act as a Wi-Fi sniffer/injector, or as a regular Wi-Fi driver.
