INTELLIGENCE FEED: Telecom Security Research Reports & Articles

The TelcoSec Intelligence Feed aggregates security vulnerability advisories, network protocol reviews, and configuration guidelines across cellular networks. This database is updated continuously by our core analysts and community contributors, serving as a tactical reference for mobile network operators (MNOs), enterprise telecommunication teams, and hardware manufacturers.

Every item in the directory is cross-referenced with active 3GPP technical specifications, detailing potential impacts on core components like the Home Subscriber Server (HSS), Unified Data Management (UDM), and Access and Mobility Management Function (AMF). Researchers and defensive architects can query the database to identify threat vectors relevant to their specific infrastructure deployments.

Additionally, the feed includes references to security guidelines from the GSMA (FASG, SECAG) and ENISA. We map theoretical vulnerabilities to real-world scenarios, offering actionable mitigation strategies and rule templates for signaling firewalls (SMS, SS7, and GTP firewalls) to help operators defend their systems in real time.

Threats are triaged using a specialized Telecom Common Vulnerability Scoring System (T-CVSS) variant. Ratings reflect potential impact on cellular service availability, subscriber identity confidentiality, and interconnect routing stability:

• CRITICALBaseband RCE, unauthenticated core bypass, or global roaming loops.
• HIGHTargeted subscriber tracking, IMSI catchers, or localized DoS.
• MEDIUMInformation disclosure, weak cryptographic suites, or bypasses.
• LOW / INFOConfiguration anomalies, general industry advisories, or auditing logs.
