Course description
The modern telecoms network is based on key principles that were introduced with SS7 (Signalling System Number 7) in the 1970s. However, it was not designed with a great regard for security, and so many vulnerabilities exist. Although later network architectures introduced more secure protocols, as well as IP-based operation, many vulnerabilities still exist in the overall end-to-end scheme.
In this course, we delve into the vulnerabilities that exist from the perspective of both the network operator and the end user. By examining these concerns, we aim to provide a better understanding of the potential risks associated with modern networks – and mitigation strategies.
These vulnerabilities include issues related to SCCP / Global Titles, Message Flooding, Network Impersonation / Traffic Injection, ISUP Layer Attacks, MAP Attacks, IMSI Catchers, USSD money transfer attacks, DoS, spoofing and scanning attacks, call interception and profile stealing.

  • Access network abuse
  • Circuit and non-circuit related signalling
  • Information needed by an attacker
  • Sources of vulnerabilities
  • SS7 / ISUP security analysis and vulnerabilities
    – Passive scanning, IAM DoS attacks, Malicious early call release, CLI spoofing
  • MTP network management vulnerabilities
  • Cellular network vulnerabilities
    – Collecting Information, Acquiring a subscription profile, MO/MT intercept
    – SMS and fraud
    – USSD money transfer
  • DoS towards the entire network
  • Attack on network resources
  • SIGTRAN vulnerabilities
  • Bombing attack

Who would this course benefit?
Organisations seeking an introduction to network vulnerabilities from the perspective of both the network operator and the end user. This includes network operators, equipment manufacturers, security solution providers, those engaged in cyber security, regulatory bodies, and government agencies.
