SS7 MAP (pen-)testing toolkit

As a lot of people run into problems building the tool, there are binary releases which can be found here:https://github.com/ernw/ss7MAPer/tree/master/releases

As people also run into problems using the binary release, there is adocker image with ss7MAPer running on ubuntu 16.04

If you use the binary version, skip right over the next chapter.

You will need:

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

• Rebar. Get it from your repo or fromhttps://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/epcap/deps ln -sd ../../pkt deps/epcap/deps/pkt 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

If all the steps above are too much to do by hand (as for me testing ;) you can use the build script here:https://github.com/ernw/ss7MAPer/blob/master/prepare_n_build.sh

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

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

In them3ua section all the M3UA parameters, like local and remote point code are configured.

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

Last but not least in thetarget 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.

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

cd ss7MAPer   rebar shell

Start the application and its dependencies with:

application:start(sasl).application:start(ss7MAPer).

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

Run the application by starting it from the root directory:

cd ss7MAPer./bin/ss7MAPer console

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

Once the application is started, there are some commands that can be executed from the erlang command line:

• ss7MAPer:test_hlr()
• ss7MAPer:test_msc()
• ss7MAPer:test_smsc()

and each of them does exactly as its called, running MAP tests against the targets defined in the config file.
