5G Interactive Attacks Flow
Step-by-step process of interactive attacks on 5G networks, including diagrams and flowcharts to visualize attack sequences.
Responsible Use Warning
The attack flows presented on this page are for educational and research purposes only. They should only be used in authorized security testing environments with proper permissions. Unauthorized use of these attack techniques against production networks is illegal and unethical.
Understanding Attack Flows
Attack flows provide a structured visualization of how complex attacks against 5G networks unfold over multiple steps. Understanding these flows helps security professionals identify attack patterns and implement effective defenses.
Each attack flow presented here breaks down sophisticated attacks into discrete steps, showing the progression from initial reconnaissance to successful exploitation. This step-by-step approach makes it easier to understand the attack methodology and identify potential intervention points.
Comprehensive Visualization
Detailed diagrams and flowcharts illustrate the attack sequence and component interactions.
Practical Scenarios
Real-world attack scenarios based on actual 5G network vulnerabilities and configurations.
Defense Integration
Each flow includes potential detection and mitigation points to enhance defensive capabilities.
5G Attack Scenarios
Attack Steps
Reconnaissance
Identify legitimate gNBs in the target area
Using SDR equipment to scan for 5G frequencies and identify cell parameters
gNB Impersonation
Configure SDR to broadcast as a legitimate gNB
Set up SDR with open-source 5G stack and configure with captured parameters
Force UE Connection
Broadcast with higher signal strength to attract UEs
Increase transmission power and use jamming to degrade legitimate signals
Capture Authentication
Capture authentication attempts from connecting UEs
Record SUCI/SUPI information and authentication messages
Man-in-the-Middle
Relay communications between UE and legitimate network
Forward modified traffic between UE and legitimate network
Detection and Mitigation
Detection Points
- Anomalous radio signal patterns or unauthorized base stations
- Unexpected authentication attempts or failures
- Unusual traffic patterns or protocol behaviors
Mitigation Strategies
- Implement strong mutual authentication for all network components
- Deploy network monitoring and anomaly detection systems
- Regularly update and patch all network components
