Threat Intelligence (Telecom-Specific)

Telecom-specific threat intelligence is the curated information about adversaries, techniques, and indicators relevant to mobile and fixed-line operators, interconnect attack patterns, fraud schemes, RAN-targeted exploits, signalling abuse campaigns. Sources include GSMA T-ISAC, vendor research, national CERTs, and dedicated commercial feeds.

Threat Intelligence in context

The radio access network is where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations and downgrade attacks; defenses rest on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.

The mobile core carries subscriber sessions, mobility and policy. In 4G it is the EPC (MME, HSS, S/PGW); in 5G it is the Service-Based Architecture with AMF, SMF, UPF, AUSF, UDM and the NRF.

To place Threat Intelligence in the wider telecom-security picture, review AUSF, Grey Routing, Red Team, SUCI, 5G and 5G SA — each entry cross-references back to this page so you can walk the topic in either direction.
