5G SBA NRF OAuth2 Token Abuse and NF Impersonation
How rogue NFs abuse missing NF Instance ID binding in NRF OAuth2 token issuance to impersonate AMF/UDM and exfiltrate 5G core subscriber data.
CORE CAPABILITIES
Protocol Fingerprinting
Deep packet inspection and state-machine analysis across GPRS, UMTS, LTE, and 5G signaling stacks.
Offensive Validation
Controlled adversarial simulations for RAN air-interface, network slicing, and multi-access edge computing.
Hardened Architecture
Zero-trust blueprints and cryptographic verification schemas for cloud-native core network deployments.
RESEARCH METHODOLOGY
TelcoSec researchers leverage custom-built SDR stacks, protocol fuzzers, and signaling testbeds to simulate real-world attacks. Every reported vulnerability is verified, reproducible, and mapped directly to 3GPP and GSMA standards — not derived from conventional IT scanners.
Coordinated disclosure cycles with global MNOs, equipment vendors, and regulatory bodies ensure vulnerabilities are remediated before active exploitation in production networks.
