Sub-GHz SDR Agent

Your radio frequency security expert that analyzes IoT wireless protocols and identifies RF vulnerabilities.

What is Sub-GHz SDR Agent?

The Sub-GHz SDR (Software Defined Radio) Agent specializes in analyzing radio frequency communications used by IoT devices, smart home systems, industrial sensors, and wireless protocols operating below 1 GHz. It identifies security vulnerabilities in RF protocols, replay attacks, and insecure wireless implementations.

Problems It Solves

IoT RF Security Gaps

Smart home devices, car key fobs, garage door openers, and industrial sensors use proprietary RF protocols with weak or no encryption. Attackers can intercept, replay, or spoof these signals.

Invisible Attack Surface

RF communications are invisible to traditional security tools. You have no visibility into what RF devices are transmitting or how secure their protocols are.

Replay & Jamming Attacks

Many RF protocols lack anti-replay protection. Attackers can capture and replay signals to unlock cars, open garage doors, or control industrial equipment.

Unencrypted Sensor Data

Industrial IoT sensors, medical devices, and building automation systems often transmit unencrypted data over RF. Sensitive information is exposed to anyone with an SDR.

How Sub-GHz SDR Agent Works

RF Protocol Analysis

Analyzes sub-GHz wireless protocols (315MHz, 433MHz, 868MHz, 915MHz). Decodes transmissions, identifies protocol weaknesses, and validates encryption.

Replay Attack Testing

Captures and replays RF signals to test for replay vulnerabilities. Identifies devices vulnerable to signal replay attacks.

Encryption & Security Validation

Validates RF protocol encryption, rolling codes, and anti-replay mechanisms. Identifies weak or missing security controls.

RF Device Discovery

Scans RF spectrum to discover all transmitting devices. Identifies unauthorized RF devices and shadow IoT deployments.

User Benefits

IoT Security Visibility

Understand what RF devices are deployed, what they're transmitting, and how secure their communications are.

Prevent RF Attacks

Identify replay vulnerabilities, weak encryption, and insecure protocols before attackers exploit them.

Smart Home Security

Test security of smart locks, garage doors, alarm systems, and other RF-controlled smart home devices.

Industrial IoT Protection

Secure wireless sensors, SCADA systems, and industrial automation that rely on sub-GHz RF communications.

Compliance Requirements

Meet security requirements for healthcare (HIPAA), critical infrastructure, and industrial IoT deployments.

Physical Security

Validate security of RF-based access control, vehicle immobilizers, and physical security systems.

Real-World Use Cases

Smart Building Security

Discovered building HVAC sensors transmitting unencrypted temperature and occupancy data. Implemented encryption to prevent corporate espionage.

Vehicle Key Fob Replay

Captured and replayed car key fob signals—successfully unlocked and started vehicle. Manufacturer upgraded to rolling code protocol.

Industrial Sensor Security

Found factory sensors using fixed RF codes without encryption. Attackers could inject false sensor readings to disrupt production.
