VoLTE Exploits
Voice over LTE (VoLTE) exploits target vulnerabilities in the IMS architecture and SIP protocol to intercept calls, perform denial of service, or manipulate call routing.
Technical Overview
VoLTE uses the IP Multimedia Subsystem (IMS) and SIP protocol for call setup and management. Vulnerabilities in SIP implementations, IMS components, and the transition between LTE and legacy networks create attack opportunities.
- •Call interception and eavesdropping
- •Denial of service to voice services
- •Call manipulation and redirection
- •Caller ID spoofing
- •Toll fraud and service abuse
- •SIP message injection and manipulation
- •IMS component exploitation
- •Media stream interception
- •Call setup manipulation
- •VoLTE to CS fallback exploitation
- 1Position as man-in-the-middle in IMS path
- 2Intercept SIP signaling messages
- 3Manipulate call setup parameters
- 4Redirect or intercept media streams
- 5Exploit vulnerabilities in IMS components
- 6Perform DoS through malformed SIP messages
- Implement SIP message validation and filtering
- Use IPsec for IMS signaling protection
- Deploy IMS firewalls and security gateways
- Enable SRTP for media encryption
- Monitor for anomalous SIP traffic patterns
- Implement strong authentication for IMS access

Related Attacks
Man-in-the-Middle attacks on LTE networks position the attacker between the device and legitimate network infrastructure to intercept, monitor, and manipulate communications.
Rogue eNodeB attacks involve deploying fake LTE base stations that impersonate legitimate network infrastructure to intercept communications and perform man-in-the-middle attacks.
Denial of Service attacks on LTE networks aim to disrupt service availability by overwhelming network resources, exploiting protocol vulnerabilities, or jamming radio frequencies.
