MELBOURNE, FL – What seemed like science fiction is today a real and documented vulnerability. Researchers at KIT (Germany) demonstrate that any WiFi network can be turned into an invisible surveillance system—without cameras, without trackers, and without the detected person carrying any device on them.
A conventional WiFi router can identify people, track their movements, and build presence profiles without anyone noticing. This technology converts every router into a potential surveillance medium. If you regularly pass by a coffee shop with WiFi, you could be identified without knowing it.
WiFi turns space into an invisible radar
Most critical: Turning off your phone is not enough. Other people's devices on the same network generate enough activity. Surveillance is passive, uninterrupted, and undetectable.
DID YOU KNOW?
- Turning off your phone does not protect you.
- Any domestic router is sufficient.
A. Sectors at Risk
GOVERNMENT & DEFENSE
- WiFi-exposed command rooms
- Vulnerable classified meetings
- Mapped personnel routines
- Standard hardware is enough
CRITICAL INFRASTRUCTURE
- Power plants and utilities
- Vulnerable mining installations
- Remote operations
- Access without physical entry
- High value
CORPORATE / EXECUTIVE
- Exposed executive boardrooms
- Industrial espionage without a trace
- Trackable personnel mobility
- Office router is enough
B. How the Attack Works
- 1. Router emits WiFi (Normal operation)
- 2. Waves bounce off people and nearby objects
- 3. Devices send BFI automatically to the router
- 4. AI analyzes the data
- 5. Reconstructs presence (Identification achieved - No trace, no alert)
C. TSG Solutions
01 Encrypted RF Networks: Secure communication without exposing WiFi in critical areas.
02 Zero Trust Architecture: Every access verified. No implicit trust on the network.
03 Vulnerability Audits: Proactive detection before being exploited.
04 Operational Training: Personnel trained to recognize the invisible risk.
D. Immediate Checklist
- Audit all routers in sensitive zones
- Eliminate WiFi in command rooms and critical meetings
- Implement encrypted RF or secure cabling
- Activate Zero Trust in your corporate network
- Train your security team

P25 System Upgrade — Seamless Migration
SCENARIO ESCENARIO
A metropolitan public safety agency needs to upgrade its radio fleet from aging P25 Phase 1 infrastructure to Phase 2 without disrupting active operations. Interlink-BK radios support both Phase 1 and Phase 2 simultaneously, allowing a phased transition where legacy units and new units remain fully interoperable throughout the migration.
OUTCOME
Zero-disruption P25 system migration with full interoperability maintained throughout the transition period.

UC-01 SECTOR: Mining — Rescue Operations
Mine Collapse Rescue Operation
SCENARIO ESCENARIO
A roof collapse at a deep underground mine traps 12 workers in a section beyond the reach of any conventional radio. Within 30 minutes of the incident, MineLink rescue teams begin deploying
relay nodes through the accessible tunnels. Within 90 minutes, voice contact is established with the
trapped workers. Command on the surface monitors the location and status of every rescue team member in real time.
OUTCOME
Voice contact and personnel tracking established in less than 90 minutes in conditions where all other communication systems had failed.
UC-01 SECTOR: Defense / Intelligence
Classified Data Transfer in a Denied Environment
SCENARIO ESCENARIO
An intelligence team operating in a fully denied communications environment needs to transfer a classified file package from one isolated device to another without generating any RF emissions,
network traffic, or detectable signal of any kind. Using Obsidian, the transfer is completed using
only the device cameras — completely passive, unidirectional, and invisible to any monitoring system.
OUTCOME
Undetectable file transfer with absolute zero electronic signature — no RF, no network, no trace.
UC-01 SECTOR: Military & Special Operations
SOF Team Communications in a Denied Environment
SCENARIO ESCENARIO
A special operations team operating in a communications-denied environment requires
secure messaging, file sharing, and coordination with a remote command element — without using
public infrastructure or exposing any metadata. Sentra Secure operates in fully disconnected mode, with end-to-end encrypted messaging, secure media transfer, and zero digital footprint on external networks.
OUTCOME
Full operational communications capability with zero exposure to external surveillance or interception.
UC-01 SECTOR: Emergency Response / Disaster
Multi-Agency Hurricane Response
SCENARIO: A Category 4 hurricane makes landfall, triggering a coordinated response across fire departments, law enforcement, National Guard units, and utility crews — all operating on different radio systems. With Nexus II deployed at the incident command post, every agency communicates in real time through their existing equipment, with no additional hardware or network redesign required. Un huracán categoría 4 toca tierra, activando una respuesta coordinada entre bomberos, fuerzas del orden, unidades de la Guardia Nacional y cuadrillas de servicios básicos, todos operando en sistemas de radio diferentes. Con Nexus II desplegado en el puesto de mando, cada agencia se comunica en tiempo real a través de su equipo existente, sin hardware adicional ni rediseño de red.
OUTCOME Seamless inter-agency coordination from hour one, reducing response time and preventing communication blackouts that cost lives.
