Diameter Attack Vectors
Comprehensive analysis of attack vectors targeting the Diameter protocol in 4G and 5G networks.

- Diameter Interfaces
S6a, S6d, S13, Gx, Rx, and other Diameter-based interfaces between network elements
- Diameter Routing Infrastructure
Diameter Routing Agents (DRAs), Diameter Edge Agents (DEAs), and routing tables
- Network Elements
HSS, MME, PCRF, and other core network elements that use Diameter for communication
- Interconnection Points
Interconnection points between different operator networks where Diameter signaling is exchanged
- Subscriber Privacy
Unauthorized access to subscriber data, location tracking, and identity theft
- Network Security
Compromise of authentication mechanisms, bypass of security controls, and unauthorized access
- Service Availability
Disruption of network services, denial of service, and degradation of service quality
- Financial Impact
Revenue loss, fraud, regulatory penalties, and increased operational costs
Key Attack Vectors
Attacks targeting the S6a interface between the MME and HSS to extract sensitive subscriber information without proper authorization.
Manipulation of Diameter protocol messages to inject malicious commands that can compromise network elements, modify subscriber data, or disrupt services.
Exploitation of vulnerabilities in Diameter routing infrastructure to redirect, intercept, or modify signaling traffic, potentially leading to service disruption or information disclosure.
Impersonation of legitimate Diameter nodes by spoofing node identities, allowing attackers to gain unauthorized access to network resources and sensitive information.
