SS7 Attack Simulator based on RestComm's jss7.

Introduction

This project is currenlty not maintained and may not build, I've made available the latest build here.

Open Source Java SS7 attack simulator that makes it possible to simulate some publicly disclosed attacks on the SS7 network.

This project is part of an ongoing Master Thesis at NTNU Gjøvik, Norway.

The simulator supports two modes:

• Simple mode: Used to demonstrate some SS7 attacks.
• Complex mode: Includes a full network simulation containing 3 operators, where one of the subscribers is the victim of attacks by an adversary with access to the SS7 network. In this mode several nodes communicate using 13 standard procedures per the 3GPP MAP standard. After a mercy period, there will be launched attacks against the subscriber with the goal of obtaining the subscribers location and intercept SMS originally sent to this subscriber.

Traffic is generated using the SCTP protocol and all data is sent on the lo interface.

Instructions

How to run the simulator:

• The simulator needs a working Java environment.
• Make sure you have SCTP support installed on Linux:
  • Fedora: lksctp-tools and kernel-modules-extra.
  • Ubuntu: libsctp1 and lksctp-tools.
• Download latest build here.
• Unzip the file.
• The simulator is launched with the script:

RELEASE_FOLDER/ss7/restcomm-ss7-simulator/bin/run.sh

• Run

run.sh help 

or

run.sh attack_simulator help 

for help on how to run the simulator.

The currently supported simple attacks are:

• location:ati
• location:psi
• intercept:sms
