Threat Hunting (Telecom)

In telecommunications, Threat Hunting is the proactive search for stealthy or low-signal adversary activity that does not trigger existing alerts. In a telecom context this means looking for abnormal MAP, Diameter, GTP, or SBA flows, unexpected NF-to-NF interactions, suspicious global title or PLMN-ID usage, and lateral movement across OAM. It relies on baselining normal signaling behavior and querying telecom-aware telemetry.

Threat Hunting (Telecom) in context

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.

Signaling protocols carry the control-plane messages that set up calls, register subscribers and route SMS. SS7, Diameter, GTP-C and SIP are the four dominant families, and interconnect exposure of any of them is treated by GSMA as top-tier telecom risk.

To place Threat Hunting (Telecom) in the wider telecom-security picture, review Vulnerability Assessment, Telecom Forensics, NTA, 5G SA, 5G SBA and ACL — each entry cross-references back to this page so you can walk the topic in either direction.
