SS7 MAP (pen-)testing toolkit

Get it running

You will need:

• Erlang. Get it from your repo or from http://www.erlang.org

• Rebar. Get it from your repo or from https://github.com/rebar/rebar

• The code (;

   git clone https://github.com/ernw/ss7MAPer   
  

• The dependencies

   cd ss7MAPer   
   rebar get-deps   
  

• Patch the dependencies

   cd deps/osmo_map   
   patch -p1 < ../../patches/osmo_map.patch   
   cd ../osmo_sccp   
   patch -p1 < ../../patches/osmo_sccp.patch   
   cd ../osmo_ss7   
   patch -p1 < ../../patches/osmo_ss7.patch   
  

• Get the deps to build (; This is not as easy as it might sound, I needed to:
  Patch the epacp/rebar.config and replace

   {port_envs, [   
     {"DRV_CFLAGS", "-g -Wall $ERL_CFLAGS"},   
     {"DRV_LDFLAGS", "-lpcap $ERL_LDFLAGS"}   
   ]}.   
  

  with

   {port_envs, [   
     {"CFLAGS", "-g -Wall $ERL_CFLAGS"},   
     {"LDFLAGS", "-lpcap $ERL_LDFLAGS"}   
   ]}.   
  

  Another dependency is not covered by rebar, so you need to fetch it manually:

   cd deps   
   git clone http://cgit.osmocom.org/erlang/signerl/   
  

  Build the ASN.1 source files:

   cd deps/signerl/TCAP/asn_src/ITU   
   make   
  

  Copy the ASN.1 files to osmo_sccp:

   cp deps/signerl/TCAP/asn_src/ITU/*rl deps/osmo_sccp/src/   
  

  Also the osmo libs have dependencies on each other and some other deps are shared, so I created some symlinks:

   mkdir deps/osmo_sccp/deps   
   ln -sd ../../osmo_ss7 deps/osmo_sccp/deps/osmo_ss7   
   ln -sd ../../epcap deps/osmo_sccp/deps/epcap   
   ln -sd ../../pkt deps/osmo_sccp/deps/pkt   
   ln -sd ../../signerl/MAP deps/osmo_sccp/deps/MAP    
   ln -sd ../../signerl/SCCP deps/osmo_sccp/deps/SCCP   
   ln -sd ../../signerl/TCAP deps/osmo_sccp/deps/TCAP   
   mkdir deps/osmo_map/deps   
   ln -sd ../../osmo_ss7 deps/osmo_map/deps/osmo_ss7   
   ln -sd ../../epcap deps/osmo_map/deps/epcap   
   ln -sd ../../pkt deps/osmo_map/deps/pkt   
  

  And copy some files in place:

   cp deps/signerl/SCCP/itu/include/sccp.hrl deps/osmo_sccp/src/   
   cp deps/signerl/TCAP/include/tcap.hrl deps/osmo_map/src/   
  

• Build the code

   rebar co   
  

The config file

The config file is split in 4 section, sctp, m3ua, sccp and target.

In the sctp section source and destination ip as well as source and destination port of the SCTP connection are configured.

In the m3ua section all the M3UA parameters, like local and remote point code are configured.

In the sccp section currently only the local (or source) global title needs to be configured.

Last but not least in the target section information about the tested environment need to be configured, like the global title of the HLR, or the MSISDN of the tested phone.

Be sure to modify it to your needs.

Running the tool

To run the tool one needs to start a rebar shell:

cd ss7MAPer   
rebar shell   

Then the SIGTRAN connection needs to be established:

Pid = ss7test_app:start(1, "./configfile").   

If everything is set up correctly the m3ua connection comes up.

To run the HLR tests, simply enter:

Pid ! {test_hlr}.
