SS7 Attacks

SS7 (Signaling System 7) attacks exploit vulnerabilities in the SS7 protocol, which is widely used in telecommunications networks. These attacks can lead to severe privacy breaches, financial fraud, and network disruptions.

SS7 Attacks Overview
Key characteristics and mechanisms of SS7 attacks
  • Exploit the trust model of SS7 networks
  • Take advantage of the lack of built-in authentication in SS7
  • Often involve spoofing or impersonation of network elements
  • Can be executed remotely, often from different countries
  • Difficult to detect due to the legitimate-looking nature of SS7 messages
  • Can affect both mobile and fixed-line telecommunications
  • Often target high-value individuals or organizations
  • Exploit interconnections between different telecom operators
  • Can bypass traditional security measures like firewalls and encryption
  • Leverage the global nature of SS7 networks for cross-border attacks
  • Exploit the legacy nature of SS7 protocols in modern networks
