Abstract

In this paper we share our experience in conducting security audits for several different mobile network operators and discuss the difficulties encountered in the process. We also describe successful attacks performed by us on Diameter equipment in these environments. Some of these attacks have not been published previously.

Author Biography

Sergey Mashukov, Positive Technologies, Russia

S. Mashukov attended Lobachevsky State University of Nizhny Novgorod, Russian Federation, receiving his B.Sc. and M.Sc. degrees in Computer Science in 2010 and 2012, respectively. Before joining Positive Technologies in 2016, he worked for 6 years on maintenance and development of a Diameter Base implementation for the one of the most deployed telecom platforms in the world.

As a telecom security specialist, his main point of interest is security of the Diameter protocol. He performs Diameter security audits for international MNOs and conducts research on the protocol weaknesses.

Sergey is also the general developer of the Diameter Vulnerability Scanner tool and member of the Telecom Attack Discovery development team.
