Talk Title

Comprehensive hacker techniques in mobile networks

Abstract

It's not a closed world anymore. Nearly all operators now admit that attackers have penetrated SS7 networks by exploiting a whole range of signaling network vulnerabilities.

Tracking subscriber location, obtaining call details, tapping, intercepting text messages that contain security codes - all that we hear over the last years. Security measures are being built but the hackers do not sit back.

Our researches alongside with security monitoring and audits show that attackers have learned how to skillfully bypass most of the known protection measures. In the presentation the following issues will be addressed:


  • What refined techniques and tricks do malefactors use
  • What unusual attack scenarios we came across in terms of security monitoring
  • How should security network specialists respond to fight newly learned hackers effectively
