Abstract:

HLR and HSS are the most important Telecom Equipment in an Operator Core Network.
We are going to see that this so-called “Critical Infrastructure” is not as robust as you could think, by exploring the some weaknesses of the HLR/HSS equipment.

Plan:
* Virtualization of HLR/HSS, for instrumentation purposes
* HLR/HSS system analysis
* SS7/Diameter network fuzzing
* HLR/HSS binaries reverse

We also did another presentation on Worldwide attacks on SS7/SIGTRAN network at HES.
