Why now
  • Recent research provides the first direct link between real-world attack traffic and mobile operator signaling infrastructure.
  • Covert surveillance campaigns continue unabated despite repeated public exposure.
  • Growing reliance on mobile networks increases the impact of these systemic vulnerabilities.
Why it matters
  • Telecom infrastructure vulnerabilities enable covert surveillance that is hard to detect and regulate.
  • The inter-operator trust model is exploited, threatening global mobile network security.
  • Persistent exploitation despite public reporting highlights regulatory and policy challenges.
