ENGINEERING_TOOLS: Protocol & Telecom Security Engineering Analysis Tools

Advanced protocol analyzers, specialized fuzzers, and injectors for carrier-grade network auditing.

Core_Protocol_Auditing

The TelcoSec Engineering Suite is designed for the rigorous demands of Interconnect Security Auditing. Our tools allow researchers to probe the resilience of the signaling planes that connect global mobile operators.

From legacy SS7 (Signaling System No. 7) networks to modern Diameter (LTE/EPC) and HTTP/2 (5G SBA) stacks, our suite provides deep visibility into protocol handshakes, routing anomalies, and security control bypasses.

A critical component of our research focuses on SCTP (Stream Control Transmission Protocol) Multi-homing. By intelligently scanning for multi-homed associations, researchers can discover hidden network paths and internal interface topologies that standard scanners often miss, revealing the true surface area of a core network.

SS7 MAP Auditing

Probing Mobile Application Part (MAP) vulnerabilities including SMS/Call interception, location tracking (AnyTimeInterrogation), and profile manipulation.

Diameter / GTP Analysis

Comprehensive inspection of S6a/Gx interfaces and GTP-U/C tunneling vulnerabilities to ensure user-plane isolation and data integrity.

Interconnect_Audit_Methodology

Effective telecom security auditing requires a structured approach that mirrors how real interconnect attacks unfold. The TelcoSec toolset is designed around a four-phase methodology: discovery, where target network interfaces and node identifiers are mapped; enumeration, where subscriber presence and routing topology are confirmed; exploitation, where protocol-level vulnerabilities are exercised; and validation, where findings are confirmed against live signaling responses.

The SCTP ORD SCAN component is particularly critical at the discovery phase. Unlike conventional port scanners, it understands SCTP multi-homing — the ability of a single SCTP association to span multiple IP addresses simultaneously. Many core network nodes are configured with multi-homed SCTP associations for redundancy. By scanning for secondary SCTP paths, auditors can discover internal IP address ranges, backup interfaces, and out-of-band management networks that would be invisible to standard TCP/IP scanning tools.

All tools are instrumented to produce structured output compatible with common SIEM and ticketing integrations. Findings include the full protocol exchange (raw TCAP or Diameter AVP-level detail), the attack vector classification per GSMA FS.11 / GSMA FS.19, and recommended signaling firewall rule signatures to block each demonstrated attack path.

Deployment & Technical Requirements

All tools in the suite are containerized and ship as Docker images targeting Linux x86-64 and ARM64 hosts. For SS7 and Diameter tools, an SIGTRAN or Diameter interconnect is required — either a direct M3UA/SCTP link to a target STP/DEA, or a test environment built with Osmocom components. The suite includes pre-built Osmocom HLR and MSC configurations for isolated lab deployments.

For 5G SBA tools, a reachable NRF discovery endpoint is sufficient. The HTTP/2 inspection components operate transparently via mTLS certificate injection and support both standalone NF testing and full end-to-end service mesh auditing via a configurable egress proxy mode.
